I don't have enough time to finish reviewing my own games, so I have to be contented with Chessbase 15's 1-click Tactical analysis will have to do for now. As a "value-add" to fellow players at Siglap South CC, I'm sharing the moves of all games captured on my DGT Board today.

Back to Playing Slower Chess
Admittedly, I have been playing and enjoying my role as a chess arbiter and partial organiser / facilitator. I still have the passion to play as well. It is not that I have not been playing much chess, hence my less recent sharing of games played. Rather, I have been playing quite a bit of unrecorded blitz games. To my surprise, my personal blitz results have improved A LOT compared to my past year(s) -- my personal chess friends could testify that my blitz play was "a joke" -- with the exception of my games played with William at Siglap South CC. (I have been whitewashed recently, but that'll be another chess story ^o^).
I have been lamenting that my play these days felt superficial. Hence, all the more these slower games felt even more precious and valuable. I have consolidated 2 such games played over the past few weeks, recording a win and a very painful loss. In both games, I play with opponents who we are very familiar with each other's play.
Again, I need to qualify that I'm just a chess enthusiast seeking to improve my game through reviewing my own thought process and decision making. In no way am I trying to give (bad) advice. But if you have any (good) advice for me, please feel free to drop a comment or PM me. Thanks ahead!
I first attempt analysing/reviewing the game on my own, followed by guessing the things I missed based on the Engine (Stockfish 10's) evaluation numbers. Corrections / Insights from the Engine will be marked in red bold.
Game 1: Adult Opponent (similar profile) v.s. newbie_learner
Time control: 45 minutes initial time, with 30 seconds increment per move starting from move 1.
1.e4 c6
1.e4 c6
2.d4 d5
3.e5 Bf5
4.h4 Diagram
What is worth mentioning in this position? My current view of the position as follows: The main reason for Black to bring the Bishop to f5 (or choose to play the Caro Kann defence in general), is so that Black can continue with ...e6 so that the light square Bishop is developed outside the pawn chain (to avoid having the bad Bishop problem present in other openings like the French Defence). After 4.h4, Black needs to be a bit cautious. Black cannot play 4...e6 immediately, because of 5.g4 and the light square Bishop will run out of squares. This suggests a need for Black to consider either 4...h5 or 4...h6 to give an escape square for the Bishop. Which one will I choose, and why?
Perhaps worth mentioning is that if White insists on forcing Black change a plan, he can play an immediate 4.g4 first. Then Black must be prepared to consider a chance of plan as Black has no time for ...e6 while keeping the light square Bishop outside the pawn chain. But that's another story.

4...h5
Objectivity aside (whether 4...h6 or 4...h5 is better), this is the only move that denies White from playing g4, to kick the light square Bishop. This assures Black that he can still play the usual play of ...e6 with the light square Bishop outside the pawn chain. Of course, this is not without any drawbacks. First, the Black pawn on h5 could be more vulnerable compared to placing it on h6. Second, the g5 square is potentially weak as the only way to control it using a pawn move is ...f6.
5.Ne2 e6
6.Ng3 Bg6
7.Bg5!? Diagram
An interesting idea. White is trying to defend the h4 pawn weakness before working on attacking h5.
An interesting idea. White is trying to defend the h4 pawn weakness before working on attacking h5.
7...Be7!?
Here, my thinking during the game, is to gain tempo if White initiates Bxe7 (If necessary, I will place my Knight from e7 to f5 to encourage an exchange of Knights on f5, so that the more natural ...g7-g6 can eventually be played. In addition, my thinking was to clarify White's intention before I consider some Queenside moves/development like ...Qa5+ or Bb4+. I had wrongly considered the possibility for White to play f4, which would have failed to ...f6! which the Bishop on g5 seems to have run out of squares (unless he gambits a pawn with f4-f5).
During our post-game review, my opponent suggested an easy and seemingly good 7...Qb6! which seems much better than my 7...Be7 that was played. Black attacks the b2 pawn while developing his Queen. I have thought of it, but I think I was misled by irrational fear-- I had been making bad Queen placements in the past. Hence, I have been avoiding early Queen development for a while in all my games.
Engine: Indeed, 7...Qb6! is the best, and the engine deems this as "Black is clearly better". I must cast aside my irrational fear based on past bad experience of misplacing the Queen to improve!
8.Bxe7 Nxe7
9.c3 Nd7
10.Nd2 Qb6!? Diagram
With 9.c3, I thought that White has already blunt Black's ...Qb6 significantly. Hence, I chose 9...Nd7 over ...Qb6 (I don't find it very good, as stated above) and 9...Nf5 (I feel that 10.Nxf5 Bxf5, Black spent a couple of moves just to exchange Knights is not acceptable from a development point of view.) After 10.Nd2, I have some concerns. Earlier, I always had the option to play ...Bxb1. My fear is that either by light square Bishop will end out being misplaced, or that the h5 weakness becomes a liability. In any case, I felt that I ran out of meaningful waiting moves, which justified my choice of 10...Qb6 -- I have developed all my minor pieces already, so by the order of development, I should be working on my major pieces -- first the Queen and then try to connect the Black Rooks.

11.Qb3 Qxb3
12.axb3 c5!? Diagram
After 11.Qb3, again, I feel that Black doesn't have much choice of non-committal moves. I initiated 11...Qxb3 based on the thinking that I have some potential playing against White's damaged pawn structure on the Queenside, and that my natural follow-up seems to be ...Ne7-f5, but I do not want to face Qa3 which is a "messy" position I do not enjoy. Hence, the decision to simplify through exchanging the Queens off the Board. I do note the drawback that the a7 pawn is pinned, and White enjoys a semi-open a-file without the need to spend a move to develop the Rook on it's original square of a1.
After 11.Qb3 Qxb3 12.axb3, I played 12...c5!? because I felt that I cannot afford to allow White to play b4 first to repair his pawn structure and lock down my ...c5 pawn break. I was prepared for some discomfort / complications arising after something like 13.dxc5 Nxc5 14.Bb5+ or 14.b3. A more ambitious wish is to initiate ...cxd4 and make White suffer with the double-isolated pawns on the b-file.
Engine: The whole business arising from 11...Qxb3 12.axb3 c5!? even though not outright losing, does not seem too good for Black. White could've accepted Black's challenge to enter into complications after 13.dxc5 Nxc5 14.b4 Nd3+ 15.Bxd3 Bxd3 16.Nb3! with space advantage AND freedom of piece development, with at least a small advantage.
Black could've avoided initiating the exchange of Queens and went for 11...c5 immediately (and wait for White to consider initiating the exchange of Queens. Something like 12.Qxb6 axb6 13.Bb5 is quite equal.
13.Nf3 cxd4
14.cxd4 Nf5
15.Nxf5 Bxf5 Diagram
After 13.Nf3, 13...cxd4 was according to Black's intention to double-isolate White's pawns. 14.cxd4 seems better than 14.Nxd4 as 15.Nxe5 Nb5!? 0-0 seems quite good for Black. I chose 14...Nf5 because I wanted to play another "waiting" move -- the Rook on h8 was doing a decent job defending the pawn on h5, and I wasn't sure whether I want to castle at all. I find ...a6 meaningless as if White wants, he could still play Bb5. At least, after ...Ne7-f5, I gained the additional option of ...Ke8-e7. One does not need to castle to connect the backrank Rooks (which some chess experts suggest this mark the end of the opening phase)!
Engine: Black should have played 14...a6 which I found meaningless during the game. Instead of committing to 14...Nf5 which only led to an exchange of pieces, 14...a6 liberates the Rook on a8 of its defensive duties. If White insists on 15.Bb5, now 15...Rc8! and it is Black, not White, who first gains access to the open c-file. The White Bishop on b5 is chased, and if 16.Bxd7+ Kxd7, Black not only has first access to the c-file but also completed opening development thanks to White being so obliging!
16.Kd2!? Ke7!?
17.Bb5 a6
18.Bxd7 Kxd7 Diagram
Both Kings felt safe enough to stay in the centre. After the game, I shared my views that I felt White would've been better to consider something like 17.Bd3 instead. After 17.Bb5, I thought 17...a6 was a great move, since it relieves my a8 Rook of its defensive duties while giving the White Bishop a Kick. I do not mind 18.Bxd7 Kxd7 since my d7 Knight was not doing much anyway.
19.Rhc1 Rac8
20.Rc3! f6!?
21.Rac1 Be4?! Diagram
I actually suggested quite a bit of improvements on both sides after the game ^o^ 20.Rc3 was smart on White's part to fix the pawn structure. I think I was confused with 21.Rac1 -- this exposes Black to White initiating the exchange of Rooks on c8 (even though White continues to "suffer" the double isolated pawn. Instead, I think Black should play 21...Rxc3 and let White decide whether to fix the pawn structure with 22.bxc3 or 22.Rxc3 to play with activity. Black should not be worried as the King on d7 has covered up the c6,c7 and c8 squares, so White Rook cannot penetrate on the c-file. Black can instead, go back to work on Kingside activity with say, ...f6 and only after then, ...Be4.
Engine: 20...f6 felt a bit shaky. To solve Black's problems, indeed 21...Rxc3 should be played. While this allows White to repair his pawn structure, at least Black won't be "tied down" due to the obligation to not exchange.
22.Ne1 fxe5
23.f3 Bf5!?
24.dxe5 Rhg8?! Diagram
These were my post-game thoughts: White could've just initiated double Rook take on take the Black King away from the center. Then White can decide how he wants to play out the Knight-v.s. Bishop endgame. Black was even more imprecise here -- I should've initiated Rxc3 while I still had the chance and only after then, decide on the deployment of the Black Rook and the Bishop on the Kingside. I think Black would be in trouble had White initiated double capture on c8 by virture of King position -- White King is far more centralised and superior.
Also, I think 23...Bg6 is better than 23...Bf5. I played 23...Bf5 to take away the possibility of White initiating g4. But the way Black did things was so slow! At least, after 23...Bg6, Black can do ...Rhf8 to work on the semi-open f-file. In any case, White really should consider initiating double capture on c8 to prove that Black is wasting time on Rh8-h7 (and de-centralise the Black King).
Engine: 23...Bf5 misses a tactical shot: 23...exd4! and after 24.Rxc8 Rxc8 25.Rxc8 Kxc6 26.fxe4 Bxe4 I wrongly evaluated that this is better for White because Black's King is far away. The central pawn mass (essentially, supported and connected pass pawns!) says otherwise! Never stop at general impressions -- calculate in big positions like this! I actually did freeze at this move (I took time to calculate), but I evaluated the arising position wrong.
Also, 24...Bf5 that was played, is much better than 23...Bg6 if White realises that he should exchange both Rooks and push the Black King back: 23...Bg6 24.Rxc8 Rxc8 25.Rxc8 Kxc8 29.dxe5. This is because eventually, Black would need to play ...g7-g6 to chain up with the pawn on h5. Hence, it would be a waste of time to move the Bishop away from g6 and then play ...g6.
25.Ke3 Rxc3
26.Rxc3 g5!?
27.hxg5 Rxg5 Diagram
Luckily, I think Black is finally proceeding in the right direction. The c-file which White Rook is looking at, is actually well-covered by Black -- the Black King on d7 took away the squares for White Rook to penetrate. On the other side of the Board, Black is actually making concrete progress with the Rook on g8. I believe the Rook on g8 must be stronger than the Rook on c3. On hindsight, perhaps White should consider taking the chance to repair the pawn structure, with 26.bxc3 instead. The Rook on c1 is well-positioned to relocate and contest on the other side of the Board / potential open files.
28.f4?! Rg4
29.b4 Be4
30.Nc2 Rxg2! Diagram
On hindsight, 29.f4 felt really unnecessary for White to me. Of course, I couldn't care too much about White's choices here, since I am very low on time. I love my find of 29...Be4 -- the White Knight on e1 is dominated, since every square it can go to is covered by the Black Bishop. After 30.Nc2 which effectively concedes at least a pawn, I know that Black probably has a winning position, but I spent so much time, I only made the move in dying seconds of the game (hence the !, not that the move 30...Rxg2 itself was anything special).
Engine: 28.f4 was indeed the critical blunder which lost the game for White. Interestingly, the best move recommended was 28.Kf4, giving the Black Rook a chase. Position after 28.Kf4 is evaluated as dead equal (0.00).
31.Nd4 Rxg3+
32.Kf2 Rg2+
33.Ke3 Rxb2
0-1
Final position of the game -- White has 25:38 remaining on his clock while Black has (only) 1:09. I guess one thing Blitz really helped me, is the courage to play when low on time. "nerves of steel" when playing under severe time trouble is something I wish to acquire.
Summary of Learning Points
1. Every game and position is unique. One should not be influenced by negative experience of the past (bad Queen placement) But in this game, 7...Qb6! would have secured a huge advantage within the opening phase).
2. Cut down on redundant moves -- 11...Qxb3, 14...Nf5, 24...Rhg8
3. "Do not initiate exchanges which benefit the opponent." is a wrong guideline to follow! The correct understanding should be, "Evaluate exchanges by first considering the outcome of initiating the exchange, followed by the outcome of opponent initiating the exchange, and choose one that makes it best for you / worst for your opponent." In this game, I attribute my bad decision to not initiate the Rook exchange on c3 (repairs White's pawn weakness) to not evaluating what happens when I wait for my opponent initiate the exchange. By "waiting", I end up getting my other Rook stuck and King stuck (as they had to prepare for the recapture on c8) and had White initiated the exchanges on c8, Black would be in trouble because the Black King will be kicked back to the backrank.
4. Black's miss after 23.f3 is a clear sign of lack of basic understanding of imbalance. I can't find any other factor to blame. I simply have to keep an open mind and not rely on generic initial impressions when making a big decision. I even froze at the move to think/calculate, meaning to say I suspect there was something but unfortunately, was unable to see through to it.
5. The outcome was a lucky one for Black. On the bright side, I do like my ability to manage the time pressure towards the end, and I'd say playing a bit of blitz games helps. There's simply no other situation allowing for one to test one's nerves (other than putting oneself under time pressure). Of course, on the other hand, I do feel that I have wasted quite a bit of time without improving the quality of my move -- e.g. I spent a long time and still did not initiate the exchange of Rooks, which is quite bad on my part. See, time spent on a move need not always improve the quality of the move when a player is not asking the correct questions of a position and answering them.

After sharing this game which I'm rather happy to have played, it's time to share a game that I feel so embarrassed of. With no disrespect to my opponent (a younger adult) who fully deserved the win, I feel that it was more of a game I psyched myself to lose throughout. Hence the reluctance to even acknowledge the existence of this game ^o^ But if a casual club player like myself can't even face a non-consequential defeat in good faith, what right do I have to preach about chess etiquette to others, or criticise the misbehaviour of kids in tournaments? I can at least better understand their misbehaviour, with everything (prize, rating points) on the line. Hence, I have always been tolerant of kids who misbehave in chess. (May my patience not wane with age!)
Game 2: Adult Opponent (Younger) v.s. newbie_learner
Time control: I can't recall for sure, but I think it was something like 25 minutes initial time, with 10 seconds increment per move starting from move 1, considered long for a rapid game (usually in Singapore, we play 15 + 10 or 25 + 0 instead).
1.d4 d5
2.Nf3 Nf3
3.c4 e6 Diagram
I don't know how other chess players feel, but I always find it difficult whenever facing a line which I play it myself =)
4.g3!? Bb4+
5.Bd2 Be7
6.Bg2 0-0 Diagram
4.g3, in Catalan style, is something I used to play a little, but stopped completely for quite a while already. My results with this opening as White were discouraging, and I thought my "general instinct" does not gel with the general demands of the opening. But I do like to play at least a bit experimentally from time to time. On this subject, I am quite in agreement with International Master and famous chess author, Jeremy Silman's general pointers: To maximise (short-term) efficiency, we should stick to what we are most familiar with (e.g. when playing in important tournaments, where things are at stake). But in the long run, we learn the most from playing into positions we do not enjoy or find unfamiliar. If I am not in an experimental mode in casual games, when will I ever have an opportunity switch on my experimental mode? Hence, my choice to play experimentally here.
Of course, one needs to find a delicate balance that works for oneself. If you keep playing experimentally and you keep losing, it may become detrimental to your self-confidence. For now, I am decently happy with my own mixture. So long as I don't lose each and every single game in a chess session, I would be in a mood for experiment. But if I am on a bad losing streak, I will switch back to my "main repertoire" to get a few wins/draws and regain my confidence first.
This 4...Bb4+ 5.Bd2 Be7 manoeuvre is something I have seen quite a bit in both high level chess and when playing training games with local kids. My understanding for the rationale of Black's moves (he Black violated the general opening principles of moving the same piece twice!) is that Black opines that White's dark square Bishop on d2 is misplaced. Hence, by provoking 5.Bd2, White will eventually need time to further improve this misplaced piece. Hence this trades off and justifies Black's loss of time -- In comparison, Black argues that his Bishop is well placed on e7.
As for the move 6.Bg2, it is the most natural -- why would you play g3 otherwise? 6...0-0 is a natural move too. So nothing too out of the blue yet.
7.0-0 dxc5
8.Qa4 a6
9.Qxc4 b5 Diagram
White may seem to be playing like a noob, keep moving his Queen, but from the little I know, this is how the Catalan is supposed to be played (if White is opting to not play with a pawn down). Other than regaining the lost pawn, White will try to provoke weaknesses on Black's Queenside pawns. The focus of the fight is on the Queenside and the centre, hardly the Kingside.
10.Qb3 Bb7
11.a4?! Bd5!
12.Qd1 b4! Diagram
I really hate myself with the 11.a4 blunder. I totally missed the power 11...Nd5 hard counter. Perhaps I was overly optimistic (I had won the first game, this is the second game played with the same opponent), and completely overlooked Black's ideas. From that moment on, I just felt horrible about my position from now on. The idea of 12.Qd1 is to move my Queen out of trouble. I am already unhappy with myself and don't want the Queen to be harassed anymore. Also, 12...b4 is very good in shutting down the Knight on b1.
LiveBook/Engine: 10.Qc2 is better. White has a few ideas, including but not limited to Rc1 (to attack c7), a3 (to stop ...b4 and facilitates Nb1-c3). If the Queen on c2 is harassed by a move like ...Be4, at least White has Qd1. With the f1 Rook brought to c1, this Queen retreat does not impede White from connecting the Backrank Rooks eventually.
13.Qe1 b5
14.Bg5 Nbd7
15.Nbd2 h6 Diagram
When I played 13.Qe1, I was hoping for some potential e2-e4 pawn push. I felt 14.Bg5 was necessary so that I can deploy the b1 Knight to d2. Otherwise, my Knight is stuck and I can't activate my Rook on a1. There is no doubt that White is worse, if not losing.
Engine: There is no doubt White is worse. On hindsight, 13.Qe1 is a waste of time. Instead, just skip this move and play 13.Bg5 immediately. With the White Queen still on d1, it is defending the a4 pawn. White must be prepared to give up the Bishop pair with natural move like e3 and try to strive for a setup that is "playable".
16.Bxf6 Nxf6
17.Rc1 Rc8
18.e3 c5 Diagram
White is trying it's best to catch up. I was uncertain about e4, and decided to play e3 instead, in case the e4 becomes an additional weakness for Black to exploit.
Engine: The verdict comparing 18.e3 to 18.e4 is not so clear. The evaluation slightly prefers e4 as it gains tempo. But this seems to be inherent engine bias. There are clear reasons/merits to consider e3 instead of e4. But if White sees itself as facing a desperate position, a more dynamic move of 18.e4 does seem better to complicate the situation (rather than 18.e3 and allow Black to continue the slow squeeze).
19.Qe2 Qb6
20.b3 Rc7
21.Rc2?! Ne4! Diagram
I did not realise that Black has Ne4-c3. So this is another complete loss of time.
Engine: Much easier is to play just 20.dxc5 -- The biggest threat from White is actually the potential to make a supported pass pawn. So let's kill this possibility when we still can.
22.Nxe4 Bxe4
23.Rcc1?! Rfc8
24.dxc5 Rxc5 Diagram
Engine: White should have tried the intermediate move of 23.dxc5, which makes it more difficult for Black to double Rooks on the c-file first. This will buy White a little bit more option on the fate of the c2 Rook.
25.Rxc5 Qxc5
26.Nd4 Bxg2
27.Kxg2 Bf6 Diagram
Engine: Black should have played this position more forcefully with 27...e5! which kicks the d4 Knight supporting the backward b3 pawn.
And now, in this difficult position (and time situation), White made a huge blunder which ended the game on the spot.
28.Nb5?? Qd5+!
0-1
The b3 pawn drops, Black pawns will promote and so White resigned on the spot. Quite frankly, White's mind was bothered by the position arising after 11...Bd5! throughout the game -- I kept thinking about it and lamenting how bad it was for me to miss it completely. Not saying that I will definitely find the saving 28.Rd1 if my mind was not messed up, but what I see as valuable lesson is that a) games can be lost if you get into a losing mentality, and b) objectively, a position, not matter how bad it may first appear, can be objectively very resilient. I have been repeating this point a lot, but I think the difference in mental resilience is a key difference between a good player and an average / club player.
Okay, I finally found the courage to face this bad loss face to face. There will only be more to come for as long as I continue to play chess. But I'd rather continue to play chess than to avoid the pain of losing a game through retirement from chess play =)
Summary of Learning Points
1. Mental resilience! The correct way to deal with a position, no matter how bad, is to deal with it at it's current state. One should not dwell in what has happened in the earlier moves. Easier said than done, I know.
This is not really a learning point for my own, but I'd like to take this chance to address chess parents who are ultra strict with their own kids just starting to pick up the game -- chess is really very difficult even for experienced / adult players! Hence, please remember to be kind and patient enough with your kids. Remember -- everyone had to go through the "beginner" stage in their bid to improve their game. Worse is to make the game of chess, already difficult to master, unenjoyable for them.
2. Avoid waste moves -- 13.Qe1 was a waste, and good intermediate moves like 23.dxc5 was missed. This should not be missed even in a bad situation. Need to hone the art of damage control, or pick correctly the "lesser of the evil".
3. Mid-endgames, pawn structures, typical weak areas of a club player =(
3. Be brave enough to face your losses, no matter how bad they were, and not just show-off your victories!

Brew Master vs Tyrant Giant Chess Blitz Match
I was privileged to be asked to serve as the match arbiter between the "Brew Master" and the "Tyrant". Both players prefer to not publicise their actual names, so only the chess friends amongst us would know who they are. These are my opinion of them:
The Brew Master is a young chess player who has proven to be a very successful local chess event organiser.
The Tyrant, despite his personal denial, is a very famous chess personality whose tweets never fail to make it onto the biggest chess sites.
There are some differences, in that we were playing under the time control of 5+3 (5 minutes initial time + 3 seconds increment starting from move #1) instead of 3+2 that was used in the previous match. But first thing's first, let's enjoy some nice pictures from the event!
Once we finish setting-up, I thought we would be ready to play. Couldn't be more wrong. Make a guess at what would be stopping us from starting right away!
Beautiful setting sun.
Apparently, even some Black Pink fans were attracted by the aesthetics of the chess pieces before the concert starts!
We actually waited quite a while for many members of the public to take pictures with the giant chess set before commencing our chess match. But once we start, it's all serious business!
Our yoga neighbours. I'm glad we weren't distracting enough to upset their tranquility!
During the course of the game, the Tyrant managed to take time to talk a distance away to take some great pictures -- while his clock is running. Do you think chess Goddess Caissa will reward him for contributing to chess promotion and publicity, or punish him for being too full of himself?
Brew Master posing before the actual commence of the match.
Since the Tyrant is the photo-taker, you are seeing the Brew Master in action.
Yes, the arbiter is watching the clock attentively and didn't move much ^o^
The match is actually ongoing! The Tyrant was taking pictures from afar and the Brew Master obliges with a pose!
There's no need to worry about nightfall as it is well lit.
A deflated Brew Master throws in the towel. This is actually done specially for a local chess lady =)
Some Boring Stuff: Arbiter's Match Report X Other Observations X Thoughts as a Chess Fan
- I tend to like to propose the "A-B-B-A" system frequently used in tennis tie breaks to even the odds/pressure of White/Black. I actually hope more chess matches consider adopting this system.
- In the first game, the Brew Master committed an illegal move which was immediately noted by both the arbiter and the Tyrant. However, the Tyrant insisted on not imposing the usual penalty of +1 minutes to the opponent, as the Tyrant was already having a huge time advantage of 2-3 minutes without this 1 minute "gift". There were no further incidents of illegal move made in the remaining 9 games.
- The Brew Master lost all games largely due to time forfeit / severe time pressure. There were at least 2 games which the Brew Master had very promising, if not winning positions.
- In some of the games, the Tyrant simply played moves which require the Brew Master to react to, where he is furthest away from the clock, due to time pressure. The Brew Master could only make a couple of Heroic struggles living on the 3 seconds increment, but not survive longer.
- There was a single moment whereby the Brew Master touched a piece, hesitated, and then simply asked the arbiter whether touch move applies in this match. Actually, the arbiter saw the incident when it first occurred, but because the "touch-move" appeared to arise out of a slip, the arbiter did not call "touch-move". It was only after the Brew Master asked, and the arbiter confirmed, that the Brew Master honoured the touch move. Precious seconds were lost. On one hand, I am really happy to see such a sporting act, on the other, I'm not sure if I am the cause of Brew Master's plight. Had I called "touch-move" on Brew Master in the first instance, those precious seconds would not be lost. But I genuinely thought it was a slip and was not seeing it as a "touch-move". Oh well. Where judgement call matters!
- There was another instance whereby the clock was paused because of an unwanted external disruption. An adult couple wanted to take pictures in the midst of a game! Even though they were making their request politely, I only wished that they could wait until the game finishes first. I am thankful that both players did not kick up a fuss and we simply paused the clock and continued after the photos were taken and the couple left the chess "board.
- Last but not least, it is important for the arbiter / organisers to "over-prepare" a little. I'm glad I brought this to put the chess clock. If not, I probably have to hold it with my bare hands throughout the match, LOL.
- As the Tyrant continues to clock more and more experience in the Giant Chess Blitz Matches, he will become harder and harder to beat. Any serious challengers should consider training him/herself up before issuing a worthy challenge!
Glad I brought this portable chair to for the chess clock to rest on. Bought this more than a decade ago when I served as a part-time assistant / runner for a Taiwanese actor who came to Singapore for filming. It also served as an additional seat option when taking the MRT ^o^
All in all, I was not expecting the Giant Chess Board to be so well-received amongst members of public. And such a match is actually very fun to watch and officiate over.

Provocation over the Board
Lost a game today at Siglap South CC Chess Club that is so... unforgiveable. I don't have enough time to analyse it move-by-move (back to office reality tomorrow!) , so I will have to rely on the "one-click" tactical analysis function of Chessbase 15 for now.
So vulnerable to such provocative approach. Oh well, learning something new every game ^o^
How white manage to lose from such a promising position is beyond me. I just played badly, and the severe time pressure and disadvantage didn't help to the situation.

Candidate Moves and Thinking Process
Introduction
As we enter into a new year based on the Chinese Calendar, I thought I'd experiment writing and presenting my chess thoughts in another way =)
This is my attempt towards self-learning. I would greatly appreciate the sharing of any thoughts or comments/feedback for learning and improvement's sake. Perhaps, if anything, you can see how a newbie in chess thinks ^o^
Thanks ahead!
Candidate Moves and Thinking Process
I will try to illustrate the concept of candidate moves through a game I played at Cashew Chess Club yesterday evening. Regrettably, I can't visit the Chess Clubs located in the West as often as I wish. In any case, this is my self-attempted review to examine my thought process. Through examining my thinking process, I hope to identify my key weaknesses / issues and seek to address them.
Adult Player v.s. newbie_learner
(As per my current practice, I will not identify my opponents in an unofficial game, unless I have specifically obtained permission to do so. As for official games, anyone who wants to know could've checked chess results anyway, so that's that.)
Even though I recorded this rapid game (15 minutes of initial time + 10 seconds increment for each move starting from the first), I did what some of my stronger chess friends in Singapore Chess Meetup suggested -- try to reconstruct the game from memory. I'm not sure if this trains visualisation or memory, but will do it since everyone recommended me doing so. I failed to reconstruct the full game based on my own memory, but I managed to get everything correct until move 18. Between move 19 and 23, I got the move order wrong, although we transpose back to the game position at the end of move 23.
1. e4 c6
2. d4 d5
3. e5 Bf5
newbie: Here is 1 of the most played line in the advance variation. An alternative would be the interesting 3...c5. It is not purely a "waste of time" to move the same pawn twice. (I suspect most fellow chess newbies would think like that on first sight, but that is not the case -- feel free to do a little bit of research on your own if you are interested.)
4.Nf3 e6
5.c4 Ne7
newbie: So far so good. I don't think there's anything too unusual. I did notice that if Black initiates 5...dxc4, White's d4 pawn becomes exposed as a backward pawn. However, that also gives White a free developing move with 6.Bxc4 recapturing the pawn. Hence, I decided to play ...Ne7 instead. I am concerned, but not overly concerned over the dark square Bishop still on f8 square. Depending on the situation, I thought Black even had ideas like ...h6 and ...g5 to consider deploying that Bishop to g7 instead, or consider challenging White's pawn centre with ...f6. The dark square Bishop on f8 didn't have that many better squares to move to anyway, so I think blocking it's scope temporarily is an acceptable "concession".
Worth mentioning is the possibility of 5...Bxg1 6.Rxg1 Qa5+ to pick up the a2 pawn. But I never believed in such manoeuvre. Whenever I play greedily like this, it almost always backfires ^o^ I'd rather stick to the general opening principles (develop, centre control, king safety). Winning a pawn in this fashion seems to help White gain development moves.
6.Bd3 dxc4
7.Bxc4 Nd5
newbie: Since White has spent a move with 6.Bd3, 6...dxc4 is no longer giving White a free tempo. I played 7...Nd5 because I want to improve my dark square Bishop from f8 to e7. Without which, I cannot castle short. I see that White has the option to play 8.Bxd5 but I'm not really concerned, since after 8...cxd5 Black's route to complete development seems easy enough: ...Be7, ...Nc6, ...Qd7 etc.
8.0-0 Be7
9.Nc3 0-0
10.Re1 Nd7
newbie: These are all normal developing moves. Worth mentioning is that I prioritise short castling for King safety. Hence I completed my Kingside development before continuing developing my Knight on the Queenside.
11.Nxd5 cxd5
newbie: On hindsight, I don't think White should have initiated this exchange of Knights. While this addresses the concern of exposing the backward pawn on d4, the centre pawns are completely locked up, and both sides will be focusing their attention to the Queenside of the Board. It's probably playable, just that I do not think that Black will be worse playing on the Queenside.
Another reason to play 11...cxd5 instead of exd5 is that the e-file remains shut down, so the value of White Rook on e1 is diminished.
12.Bd3 Bg6
newbie: The candidate moves I saw for Black were 12...Bxd3, 12...Bg6 and 12...Bg4. Before that, I felt obliged for my Bishop on f5 to move in response. Otherwise, Black's pawn structure will be damaged after White plays Bxf5.
I did not want to initiate 12...Bxd3 because I thought that simply helps White to develop the Queen to d3 "for free". I some time concluding that 12...Bg6 is a better move than 12...Bxd3, since if White initiates 13.Bxg6 hxg6, my argument is that despite the slightly weakened pawn structure, Black has gotten rid of a potential backrank issue -- often when the major pieces faces each other off (very likely when fighting over the control for the c-file in this case), we want to make sure there is no backrank checkmate. And the most common way to do that is to make a pawn move on the Kingside for the King to escape. Hence, if White initiates Bxg6, I argue that Black has saved 1 move for this purpose.
Admittedly, I did not spend enough time to compare with 12...Bg4, pinning the White Knight on f3. I see nothing wrong with this in my post game review. During the game, I had some concerns over whether Bxh7+ is a possibility. I think I'm "seeing ghost" =)
Engine: After 12.Bd3, the engine recommends 12..Bxd3 13.Qxd3 Nb8 un-developing the Knight temporarily to relocate it to a better square of c6 to pressurise the d4 pawn.
After 12...Bg6, the engine recommends 13.Bxg6, and opines that White has advantage if Black recaptures with 13...hxg6 14.g3 or 14.h4 immediately, imagining a direct Kingside attack. (13...fxg6, opening up the f-file for the f8 Rook maintains equality).
Same thing in subsequent moves, the engine opines that Black should have just taken on d3 to avoid even that little bit of pawn weakness on the Kingside, and that White should have initiated Bxg6 to create that weakness (and attack Kingside!)
What can I try to learn from this: Don't under-estimate pawn weaknesses, especially over the Kingside when there is still some attacking potential. The easiest for Black is to go for 12...Bxd3.
13.a3 Qb6
14.b4 Rfc8
newbie: White decides to expend his Queenside space while Black decided to complete opening development by connecting the backrank Rooks. I chose to move my f8 Rook instead of my a8 Rook to c8 in view of a number of considerations. First, I actually have some concerns over White playing Qa4 (it's better for the Rook on a8 to remain to keep the a7 pawn protected without committing the Black Queen to b6). Second, when asking myself which is the "worst placed piece", I actually feel it should be the f8 Rook -- I may want to push my a7 and b7 pawns eventually, since we are fighting on the Queenside. Third, from a defensive point of view, I may want or need my undefended Knight on d7 to be relocated to f8. All these factors prompted me to play 14...Rfc8.
15.Bg5 Qd8
newbie: White's move surprised me. I thought White would play something like 15.Bb2 as an attempt to shut down the c-file, diminishing the value of my Rooks / major-pieces on this open file. I spent quite a bit of time on this move. First, I find 15...Bxg5 unappealing, if not potentially disastrous. Specifically, I do not even want to entertain the thought of 15.Bg5 Bxg5 16.Nxg5 with some Qf3 ideas after exchanging off the light squared Bishops. I also ruled out the possibility of winning a pawn with 15.Bg5 Bxg6 16.Nxg5 Qxd4, because the tactical considerations have not ended: 17.Bxg6! Qxd1 (the Black Queen is undefended) 18.Bxf7+ followed by 19.Rxd1 (either Rook) would be disastrous for Black.
So I have ruled out initiating the capture on g5. But my Bishop on e7 is also hanging. Luckily I found 15..Qd8, a move I liked very much. The Queen on b6 does not seem to be doing a lot -- the d4 pawn is immune for now. The Queen on b6 is also arguably misplaced -- it is stopping my Queenside pawns from advancing to fight back. Above all, I now see potential for my d7 Knight to be routed to b6 and challenge for control over c4 and a4 squares.
Engine: 15...Bxg5 is still better. If White realises 16.Bxg6, Black must find 16...fxg6 rather than 16...hxg6.
What can I try to learn from this: Got to realise the dynamic possibilities of ...fxg6 -- Black can at least plant a major piece on f8 to fight back. With ...hxg6, Black has no such possibility.
16.Bf4 Nb6
17.Rc1 Rxc1
18.Bxc1 Rc8
newbie: I kind of understand 16.Bf4, although I think White might as well have initiated mass exchanges with something like 16.Bxe7 Qxe7 17.Bxg6 hxg6 18.Rc1. I thought this makes the position easier to hold. 16.Bxe7 Qxe7 pulls the Queen away from the backrank, which undermines Black's efforts to pile up the major pieces on the c-file. 17.Bxg6 liberates the White Queen of it's defensive obligations over the d3 light square Bishop. After what was actually played in the game, I felt Black definitely has something-- just a matter of whether it is sufficient to win the game.
19.Qd2 Qc7
20.h3 Qc3
newbie: 19.Qd2 feels like White Queen is still burdened by the need to defend the light square Bishop on d3. Here, I decided to double my major pieces on the c-file and do what I can to exploit for maximum damage. Time factor (I was down on time) contributed to my decision to play 20...Qc3 as an attempt to simplify rather trying 20...Nc4. In any case, I thought that it was unwise to play 20...Nc4 since White has the resource of 21.Bxc4 anyway. Notice that White spent a move 20.h3 to give an escape square for the White King. In comparison, Black was waiting for White to initiate Bxg6 to save a move.
21.Bxg6 hxg6
22.Qxc3 Rxc3
newbie: These moves aren't exactly "forced" or only moves, but White's position feels difficult, and I can understand why White was "encouraged" to play them. Now Blacks moves are much easier to find -- consider ...Nc4 or ...Na4 and work on White's hanging pawns.
23.Bb2 Rc2
24.Bc1 Nc4
25.Bg5 Bxg5
26.Nxg5 Nxa3
27.Ra1 Nb5
newbie: Even when reviewing the game after its conclusion, I'm not sure if 23...Rc2 or 23...Rb3 is more accurate. During the game, I was quite down on time at this juncture (probably at 1 minute or less). So I thought that minimally, I do not want to risk giving up control over the c-file to any mistakes. And my opponent admitted that he did not realise that 27...Nb5 defends the a7 pawn. Not only is Black 1 pawn up, White's pawns, particularly the d4 and b4 ones, are still vulnerable. These factors should be decisive for the game.
28. g4 Kf8
29.Kg2 Ke7
30.Nf3 Rc4
newbie: Here I just want to stay as safe as possible. 28...Kf8 was to take away any potential backrank (the Knight on g5 took away h7 square from Black King). 29...Ke7 is centralising of the King, and moving towards the side of the board where it counts -- my pass pawns will emerge on the Queenside. I believe I still have just enough on the Kingside to not allow White to make a meaningful pass pawn. In fact, the doubled pawns are very useful to stop / slow down White's pawn advancement on the Kingside. 30....Rc4 threatens to win more loose pawns.
31.Rb1 Nxd4
32.Nxd4 Rxd4
33.Rc1 Rc4
newbie: consistent with the plan to stay safe. After grabbing the d4 pawn, Black is ready to offer exchange of Rooks with 33...Rc4. On hindsight, perhaps 33...Kd7 is better. The King on d7 has already taken away the c6,c7 and c8 squares from White's Rook, while the Rook on d4 is still pressurising the b4 pawn.
34.Rb1 Kd7
35.b5 Kc7
36.Kg3 Kb6
37.h4 Rc5
38.h5 Rxb5
This was the last recorded position. Black proceeded to win the game after more moves were played.
0-1
