FT article: The sports helping executives stay at the top of their game

The latest Financial Times article involving chess - "The sports helping executives stay at the top of their game" - sadly was evidently written by non-chessplayers. How could I tell? From this quote:

Chess is not a solved game: despite the computing advances, there is no known perfect way to play it. But for some, it is too controlled an environment to offer a window into the real world — too little emotion, too many pre-planned sequences. How much can you learn about life from a sport that machines play far better?

There are several things wrong with the above statement, but the primary tipoff was the "too little emotion" part - no one who has played a serious game would ever say that, including Magnus Carlsen when he loses. The part about not learning from life in anything that machines "play [or do] far better" would mean abandoning all sorts of activities in modern life. I suppose we should all stop writing and drawing now that generative AI exists?

The other chess quote from the article is more on point:

Demis Hassabis, co-founder of Google DeepMind, became a chess master aged 13. He attributes his early interest in AI to playing chess “and trying to improve my own thought processes”.

And I would say an article quote on tennis is also very applicable (see Chess vs. Tennis here for more parallels) and one of the reasons I enjoy chess as a pastime:

“There’s no favouritism, there’s no politics. You either win or lose based on how you perform in the moment.”

Annotated Game #311: Karma in the KIA

Continuing the karma theme from Annotated Game #310, this last-round draw should have been a win for my opponent, who did a good job outplaying me in a Caro-Kann King's Indian Attack (KIA) middlegame. He then missed some defensive tactics leading to an imbalanced queen vs. rook and knight (and pawns) endgame, which I could have won.

In the KIA setup, Black has some unclear strategic decisions to make regarding where to put his light-square bishop (and when), along with keeping the center mobile or advancing with d5-d4. In this game I make bad choices in both cases and the punishment is enlightening. The other overall learning theme I came away with was the superiority of active defense, which is highlighted in several variations analyzed.

1.e4 c6 2.d3 d5 3.Nd2 heading for the King's Indian Attack e5 4.Ngf3 Bd6 5.g3 Nf6 6.Bg2 0-0 7.0-0 Re8 8.Re1 Nbd7 this is the first real think for me now, although I had to concentrate a bit to remember to bring the rook out on the previous move. 8...Bg4 here also scores well in the database. 9.a4 a5 a near-automatic reaction. Black wants to play this anyway, to contest the b4 square, while also preventing White's pawn from advancing further. 10.Nf1 Nf8 next big think here, about the middlegame plan. The idea is to free up the Bc8 while preparing to go to g6 if necessary. 10...d4!? I considered to prevent White's next move, but I felt it was too committal. 11.c3 c5= 10...h6 this prophylactic move controls g5 and also acts as a waiting move, putting the question to White about what to do next, without committing Black unnecessarily. 11.Ne3 I assessed this as being stronger than it actually was, threatening to go to f5 and hit the Bd6. d4 11...Ng6!? would be more consistent with my previous move and leave the central tension in place. 12.Nf5 Bc7 and 13.exd5?? breaking up Black's center is of course now refuted by Bxf5-+ 12.Nc4 here the knight avoids being exchanged on f5, and after some thought I overly complicate matters in response. Bb4?! I liked the idea of controlling c3, but this just improves White's position in relative terms. 12...Bc7 simple and best, according to the engine. 13.c3 b5 14.axb5 cxb5 15.Na3 b4 16.Nc4 dxc3 17.bxc3 Ba6= 13.Bd2 the simplest response. Ng6?! passive defense. 13...Bg4= effectively gets the bishop into play, with the pin on the Nf3 protecting e5, and it can usefully exchange off White's good knight. 14.c3! White now seizes the initiative. Bc5?! 14...dxc3 15.bxc3 Bf8 15.cxd4± White gladly exchanges the central pawn and my strong bishop. Bxd4 16.Nxd4 exd4 17.f4 now the pressure is really on and I have trouble coming up with a good defense. Nf8? 17...Be6!? there is nothing better; here I did not adequately consider/calculate the pawn fork after 18.f5? 18.b3± 18...Bxc4! 19.fxg6 Be6= 18.f5+- White controls the center and his active pieces and advanced f-pawn threaten my king. N6d7 19.Nd6 Ne5 I decided to make a defensive exchange sac, since otherwise I felt White would simply squeeze me to death. 19...Re7 is the engine's choice, but with a similar idea in the variation 20.Nc4 Ne5 21.Nxe5 Rxe5 22.Bf4 Nd7± 20.Nxe8 Qxe8 21.Bf4 Nfd7 the idea is to set up as much of a blockade as possible. 22.Qc2 c5± White is up the exchange and has the two bishops, but my defense is starting to form. 23.Rad1 b6 24.h3 24.g4 is the hard-to-find engine move, with the point being Nxg4? 25.e5 with a discovered attack on the Ra8 Ra7 26.Qe2+- 24...Ba6 with my last minor piece now developed usefully, hitting d3, I've whittled White's advantage down some. 25.Qb3? this just loses a pawn, although I was too timid and also did not seriously calculate the idea of taking with the bishop on d3. Rb8?! 25...Bxd3! and if 26.Rxd3? I did not see 26.Qa3 Ba6 26...c4!-+ the knight protects the c-pawn, the crucial difference in choosing which piece to take with on d3. 26.Qc2 eliminating the pawn fork tactic. Qe7 developing the queen to a better diagonal. 27.Qe2 f6?! now is when active defense/counterattack would be best. However, I was still focused on creating a fortress. 27...b5 28.axb5 Bxb5= 27...g5!? 28.fxg6 hxg6 29.h4 c4 30.dxc4 Bxc4= followed by ...d3 is an idea I saw, but judged too risky. 28.g4 Qf7 eyeing the penetration possibility on b3 29.g5 again I miscalculate the defense. Kh8 29...fxg5 30.Bxg5 Qb3! 30.Kh1 Rg8?! 30...fxg5 31.Qf2 Nxd3 unfortunately this does not work objectively, but it was certainly a shock to my opponent, and I erroneously thought it was my best chance. 31...fxg5! eliminating the g-pawn first is necessary. 32.Bxg5 Nxd3 32.Rxd3 Bxd3 33.g6!+- Qe7 34.Qh4 Nf8 best and only move that does not immediately lose. My opponent appeared surprised, and was getting low on time. 35.e5?? attempting to increase the pressure, but this allows Bxf5-+ and he apparently missed this backwards bishop move. Black is now winning. 36.exf6 Qxf6 37.Bg5 Qxg6 38.Bd5 I now block with the wrong minor piece, having missed White's follow-up. Be6? 38...Ne6! and Black is now simply a winning amount of material up. 39.Rxe6! Nxe6 40.Be4 this is what I missed. Now I find the drawing continuation, which seemed to surprise my opponent. Qxe4+ 41.Qxe4 Nxg5= the engine rates this as a draw, but of course with the major imbalances involved either side could still blunder, especially since we were both low on time. I would say winning chances practically are with Black, due to the extra pawns. 42.Qf5 h6! now I should not have to worry about losing by force. 43.h4 Nh7 44.Qd7 Rf8?! 44...Nf6 much better having this move come with tempo, and the engine even assesses Black is now winning. 45.Qd6 Re8 46.b3 Kh7 47.Qxb6 Re5-+ 45.Qd6 Rf6 the idea was to maintain an easy draw with the 6th rank defense. 46.Qd8+ Rf8?! this was an unnecessary (and unintentional) pawn sac, but the evaluation stays the same. 46...Nf8 47.Qxb6 d3= the power of the advanced passed pawn outweighs the queenside pawn weaknesses for Black. 48.Qd6 c4 49.Kg2 Re8 50.Kf3 Nf6 51.Qd4 Re4 52.Qd8+ Kh7 53.Qxa5 Rxh4 54.Qf5+ now there is no way to escape the checks. Kg8 55.Qe6+ Kh7 56.Qd6?? 56.Qf5+= 56...Ne4? this is good enough for the draw, but the engine shows a win after 56...Rh3+! 57.Kg2 Rh5-+ as White cannot prevent the rook from going to d5 behind the passed pawn. 57.Qd5 d2 58.Qf5+ and we're back on the check circuit. Kg8 59.Qe6+ Kf8 60.Qc8+ Ke7 61.Qb7+ Kf6 62.Qc6+ Kg5 63.Qd5+ Kg6 64.Qe6+?? 64.Qc6+= 64...Kh7 unfortunately I didn't have enough time to calculate the alternative, so agreed a draw here. 64...Nf6!-+ without another check by White, Black's rook can now get behind the d-pawn, for example after 65.Qe2 65.Qd6 Rh3+ 66.Ke2 Rd3 65...Rh3+ 66.Kg2 Rd3 ½–½

Annotated Game #310: A just result (karma-wise)

I unexpectedly had two Whites in a row in this tournament, so was able to immediately rectify my error of an incorrect e3-e4 pawn push in Annotated Game #309 with an example of a correct e3-e4 pawn lever. The difference here is that Black closes the center early, making the pawn break possible since White's d-pawn cannot be undermined or exchanged as a result. My opponent then makes a tactical error which should have led to a loss, but I fritter away my advantage into an even endgame. A late blunder as we officially agreed a draw was bad, but given that I should have easily won earlier, perhaps it was just karma evening out.

1.d4 d5 2.e3 Nf6 3.Bd3 e6 4.f4 c5 5.c3 Nc6 6.Nf3 c4 this decision by Black to close the center now makes the e3-e4 pawn lever White's main (correct) idea. 7.Bc2 b5 8.0-0 a5 9.Qe2 the idea is to support the e-pawn push, while getting the queen off the back rank. 9.Nbd2 followed by e4 is better for development, however. 9...Be7 10.Nbd2 b4 11.e4 while Black's queenside pawns are further advanced and therefore control more space, White's central play more than offsets this. a4 12.Ne5 Qc7 13.Nxc6 bxc3? after a long think, my opponent goes for this trick option, which should in fact lose. 13...Qxc6 14.e5 Ng8 and White only has a slight plus, but this must have looked unappetizing. 14.Nxe7! also played after a long think, to make sure it worked tactically. cxd2 15.Nxd5+- the key follow-up. Nxd5 16.Bxd2 Nf6 17.Bc3 another long think here. While this isnt bad, I should have prevented castling instead. 17.Bb4 and White's task is much easier with the king in the center. 17...0-0 18.d5?! this unnecessarily loosens central control and gives back much of White's advantage. 18.a3 is simple and locks up Black's a-pawn while giving the bishop a postential outpost on b4. 18.Rac1 also works after a3 19.bxa3 Rxa3? 20.Bb4! 18...Qb6+?! 18...exd5 19.e5 Re8± 19.Kh1± exd5 20.exd5?! an example of too-materialistic thinking. 20.e5! Bg4 21.Qe1 d4 22.Qf2+- a nice tactical finesse with the pin, which I did not see. 20...Re8 21.Qf3 Re3?! 21...a3 breaking up the pawns, one way or another, would essentially equalize. 22.Qd1?! 22.Qf2!+- again missing the pinning idea. 22...Bg4 23.Qd4 the best choice. 23.Bd4 Qd6= 23...Qxd4 24.Bxd4 Re2 25.Bd1 Rd2?! 25...Re4 26.Bxf6 seizing the chance to inflict structural damage on Black. Rxd1 27.Raxd1 Bxd1 28.Rxd1 gxf6± Black's fragmented pawn structure gives White an obvious edge, but as the saying goes, "all rook endings are drawn" 29.Kg1?! 29.a3 again is a key idea, preventing the advance of Black's a-pawn. 29...Kf8 29...a3!= 30.Kf2 now my opponent recognizes the idea of the a-pawn advance, eliminating Black's pawn weakness on the queenside, after which she can cover the kingside adequately. a3!= 31.bxa3 Rxa3 now it's a draw. 32.Rd2 32.Rc1 Rxa2+ 33.Kf3 Ra4= 32...Ke7 33.d6+ Kd7 34.Ke2 c3 35.Rc2 Kxd6 36.Kd3 f5 37.g3 Kd5 38.h3 h5 39.Rxc3 Rxa2 40.Rc2?? if exchanged, this is now a lost K+P ending. I was hallucinating under time pressure and did not see how Black's king could penetrate. However, my opponent also was tired of the struggle and took the draw. 40.Rb3 Rg2 41.Rb5+= 40.Ke3 Rg2 41.Kf3= ½–½

Annotated Game #309: Don't assume the move is good

In this next tournament game, I make two bad assumptions about a move being good, and am punished for it. The first one is the e3-e4 break in the Stonewall Attack, which has to be more carefully prepared. The second one is the result of a hallucination and assuming that I could escape a pawn fork, which in fact I could not. For whatever reason I was more mentally tired than I should have been during the game, which led to the unfortunate short-circuiting of my thinking process.

Nxe5 12.fxe5 Nd7 13.Qh3 g6 14.e4? this looks active, but unfortunately the e-pawn break idea is not supported sufficiently. 14.Nf3 f6 15.exf6 15.g5!? fxg5 16.Qxe6+ Kg7 17.Qg4 Bc8 18.Qg2= 15...Nxf6 15...Bxf6 16.g5 Bxg5 17.Qxe6+= 16.Bd2 Ne4 17.Bxe4 dxe4 18.Ne5= 14...Bg5?! this should let White escape after exd5, but instead I play 14...cxd4 15.cxd4 b5 taking away the c4 square from White's minor pieces. 16.exd5 Qb6 White's center is not sufficiently defended. 17.Nb3 Nxe5 15.Nf3?? my "internal board sight" failed here - of course after the Bc1 is exchanged the knight cannot go to g5, which I hallucinated, because of the Qd8 covering the square. I was mentally tired and prematurely cut off my own thinking process, with plenty of time on the clock. 15.exd5 Bxd5 16.Be4= 15...Bxc1 16.Raxc1 dxe4-+ and now the game is effectively over, although I try for a swindle based on a desperate kingside attack. 17.Qh6 exf3 18.Rce1 cxd4 19.Be4 Bxe4 20.Rxe4 f5 21.gxf5 Rxf5 22.Rh4 Qg5+ 0–1
