Annotated Game #207: April Slow Chess League 45/45, Round 1

While I enjoy over-the-board (OTB) play and get more out of it, slow time control play online is a good substitute when I can't go to tournaments.  This month I completed the April 45/45 tournament at the Slow Chess League, playing three rounds out of four (one week was a bye for me). I played reasonably well and successfully adapted back to a faster time control than I've been playing in OTB tournaments, so I'll count it as a successful re-entry into online play.

This first round game I faced as Black the popular 1.c4 2.g3 setup in the English, which is playable against anything Black does. I don't think it's a real threat to my repertoire, but it was only the second time I'd played against it; the first time, my opponent did not opt for an exchange on d5. I found the resulting position a little awkward, having missed an opportunity to enter a more standard Slav setup on move 6. Black is stuck defending for a while and both of us missed a (very difficult to see) tactic for White on move 16 that Komodo pointed out in analysis. I finally found my way to equality on move 18 and was content with a draw afterwards, although I could have kept some pressure up with the ...e5 break in the center.

It wasn't a bad start to the tournament, and was a good re-introduction to the practical choices one needs to make in a tournament game.

Training quote of the day #23: Mark Dvoretsky

From Mark Dvoretsky's Recognizing Your Opponent's Resources:

Your opponent also has a right to exist - Savielly Tartakower remarked with his characteristic irony. Absorbed in our own thoughts, we sometimes forget this, for which we have to pay dearly. As Viktor Kortchnoi wrote, Well, if you do not check what your opponent is doing, you will end up complaining about bad luck every game. No chessplayer has managed to completely exclude this kind of mistake, but some make it less often and others more often. Many who are over-self-confident optimists make it with unenviable regularity.

Training quote of the day #22: Tigran Petrosian

From the Chess.com article "Chess Plans, Losing Streaks and Petrosian Speaks" by IM Jeremy Silman:

Viktor Khenkin’s question:

There is a widely-held opinion that the only players that enjoy competitive longevity are those who base their play not on the calculation of concrete variations but on positional understanding. In short, their play is founded on general positional considerations. Such a method allows a player to expend less energy, and hence to withstand better the tension of a tournament game. Is this true?

GM Tigran Petrosian:

I do not share this point of view. Positional understanding is indeed a sign of the great practical strength of a player. But with the years this skill also becomes blunted. It must be constantly stimulated and modernized; in other words a player must work on chess art and analyze.

But on positional understanding alone you will not go far. Without sharp tactical vision there is no chance of success. But as a player grows older his calculating capacity is markedly reduced, and he has somehow to compensate for this deficiency. Why did Botvinnik retain for so long his great fighting ability? Because he was able to recognize this irreversible process earlier than others and to ‘reprogram’ himself. In what way? In the same way as I am doing now.

Although I have never been assigned to the category of ‘chess calculators,' in my youth I used to work out at the board an enormous amount of variations. I used to calculate them quite quickly and quite deeply. Today too I can calculate deeply and well, only not for five hours at a stretch. I can now switch on my ‘calculating apparatus’ at full power only once or twice during the course of a game. Therefore I try to choose my openings and build up my play so that there is no need to analyze variations move after move. But if at a critical moment such a necessity suddenly arises, I can cope with this no worse than I used to.

Commentary: Dortmund 2017, round 1 (Kramnik - Fedoseev)

Continuing with the commentary theme of the Caro-Kann Exchange variation at the super-GM level, the below game is from the first round of Dortmund 2017, featuring Kramnik as White. He makes a non-standard choice of 6. Na3!? which leads to some unbalanced play and a clash of ideas in the middlegame. Black (Fedoseev) deliberately leaves his king in the center and weathers a White attack with some classic Caro-Kann themes, including the half-open e-file and sacrifice on e6. Black's cool nerves give him the victory in the end.

Na3 {a rare continuation, but with precedent.} a6 { essentially forced, in order to keep White out of b5. One could argue that the time-wasting moves cancel each other out in terms of tempi, but I would say that ...a6 is more useful to Black than White's knight moves are for him.} 7. Nc2 {where else?} Nf6 8. h3 {now White considers it best to prevent a future pin on f3 after ...Bg4, as Be2 would be a time-wasting retreat. Ne2 has also been played here.} e6 {shutting in the Bc8, but now there's nowhere for it to go on the kingside.} 9. Nf3 b5 {making room for the bishop on the queenside.} 10. O-O Bb7 {while it doesn't look well-placed here, in fact the bishop is able to influence the e4 square to good effect.} 11. Re1 Bd6 {the most dynamic option for bishop development. Black reinforces his control of the b8-h2 diagonal and doesn't worry about Bg5, which under other circumstances would be annoying. However, there is a tactical reason why it's not best for White, as we'll see.} 12. Bg5 (12. a4 {played immediately is what the engines recommend.} bxa4 13. Rxa4 O-O 14. Qe2 Ne7 15. Bxa6 Qb6 16.

However, I can understand how Fedoseev might not think that the best course in the long run, given White's extra passed b-pawn.}) 14. c4 {it appears here that Kramink didn't want to go down the road of capturing on e4 or a4, which did not promise more than equality. White also hopes to take advantage of Black's uncastled king position.} (14. Bxe4 dxe4 15. Rxe4 h6 16. Bc1 Ne7 17. Re1 O-O $11) (14. Rxa4 h6 15. Be3 O-O $11) 14... Nxg5 15.

However, it's not much fun to play as Black, with your king in the center and your opponent having open lines and initiative.}) 16. Bxc4 {White has sacrificed a pawn for open lines and an attack. The half-open e-file and sacrificial possibilities on e6 are classic Caro-Kann themes for white.} Nd8 $5 {visually this seems rather strange, retreating the knight and leaving the king in the center, but perhaps gives better chances for Black than the alternative.} (16...

Book completed: How Chessmasters Think

I recently completed How Chessmasters Think by IM Paul Schmidt, who was a strong Estonian player in the Paul Keres era and subsequently emigrated to the United States.  I ran across the book largely by accident a while ago and got it on Kindle, it being hard to find otherwise.  It's rarely referred to in chess improvement literature, but the subject matter seemed to be very relevant.

Rather than a tutorial on how chess players should think, the book is more of a descriptive exercise in how master-level players do think during a game, both on a theoretical and practical level.  The author presents a series of annotated games, but rather than talking about the ideas or giving analysis in the usual method, instead writes annotations based on an imagined thinking process for each player.  Essentially, he answers the question "why did the player choose this move" with a thought experiment for both sides of the board.  Periodically he will also introduce an objective voice (the "critic") when critical moves are overlooked by both players.

I found several advantages to the author's approach and learning benefits from the content.

• Some clear and valuable explanations of specific strategic considerations in main line openings, especially relatively early choices, which all too often are skipped over.
• Each of the chapters has a theme regarding chess situations and judgment which can be generalized, at least to some extent, in terms of facing similar future decisions.
• The games themselves are varied and high-quality, with frequent appearances by world-class players such as Keres, Alekhine, and Euwe, along with games involving Botvinnik, Fine and Capablanca.  Some lesser master games are also included that are relevant and interesting, by people known to the author.
• The combination of strategic and tactical considerations as part of each side's "thought process" emphasize the practical aspect of thought, rather than pure strategy or tactics, as is often presented.

A couple things were less helpful, from my perspective.

• A few move typos are scattered throughout the book, in both the game score and given variations.  Most of the time it's clear what the move should be (for example Nc5 instead of Ne5), but in one or two spots it was really head-scratching.  I expect this was due to the Kindle OCR conversion process.
• The author has the tendency to include 2-3 pages of variations of 8-10 moves and stream-of-consciousness thought in the early middlegame, which make it difficult to keep following the thread.  He admits late in the book that most chess masters will calculate 3-4 moves ahead in non-forcing situations, but that it is necessary to go further when necessary.  So the stream-of-consciousness over the length of a long variation sometimes comes across as a bit artificial.  On the positive side, the moves then play out as part of the game, which makes it much easier to understand what is actually going on.
• While it's good to have to work things out for yourself, I found some annotations and explanations cut off a bit prematurely or were of the "...and wins" variety, when it wasn't immediately clear why it would win (eventually).  The author seems to have been assuming an advanced (around master-level) audience in those cases.

I would say that players around Class B and up would benefit from the book, which isn't terribly long (16 chapters / games).
