Annotated Game #220: Second chances in the Dutch

The theme of this game, as well as being an example of the (desperate) second chances the Dutch can sometimes offer, could also be "Why You Should Never Give Up in Chess". This was my second tournament game with the Stonewall, coming about a year after Annotated Game #175. As can be seen, I'm still feeling my way forward in understanding the needs of the position and best locations for the pieces. White's 12. Ne5 highlights the weaknesses and awkward development that Black has at this point. However, analysis also shows the resilience of the Stonewall, as it is hard for White to make measurable progress even with a noticeable positional plus. The equalizing idea of the ...e5 pawn break (not played in the game until later) is particularly noteworthy.

On move 22, I start a rather rapid downward slide, with White establishing a positional bind on the queenside. Due to blunders on move 25 and 28, by move 30 my opponent is a piece up in a far superior position. I could have given up, but instead decided to play on and try to exhaust all opportunities for complicating the game and giving White a chance to go wrong. Essentially Black has to go "all in" on creating possible central and kingside threats. Move 35 is the last shot at this, which in fact worked in a spectacular way, as my opponent overlooked in the ensuing sequence an exchange sacrifice deflecting his queen away from protecting his king. From that point, the win was technical.

This game helps illustrate some of the psychological and cognitive factors behind winning and losing moves. My two blunders occurred under pressure and involved missing longer-range bishop moves / square coverage, the first being a backwards bishop move. My opponent's game-ending mistake occurred in a complex position where the "obvious" move seemed good enough and the alternatives were more difficult to calculate.

On the positive side, when I committed to staying in the game on move 30, I was then able to focus on possible tactical resources and accurately calculate them. This often happens in a game when you accept that you are objectively lost, which paradoxically releases psychological pressure, as the worst case scenario has already happened. With nothing left to lose, more energy can be directed into trying to fight back than in worrying about potentially losing. I think part of the process of improvement is fostering the ability to have that kind of worry-free focus before you actually get into a lost position.

Annotated Game #219: The usual start to a tournament

This first-round game is from the second breakthrough tournament I had to reach the Class A level. It got off to what is unfortunately something of a usual start for me, with below-average play leading to a relatively quick end. It's tempting to ascribe these kinds of first-round losses to needing to "warm up" or "shake off the rust" or other similar excuse, and I do think there is some truth to that. However, that makes it all the more important to take lessons away from these games, so that your "default" level of play can improve, even when your brain is not at peak performance.

In this game, there are several key moments and ideas to point to:
  • The choice of 4. d3. Here I was mashing together different lines of the English from my preparation (5. Rb1 is actually not bad...in a different variation) and while the opening isn't the main point of failure of the game, it gave Black a freer hand than was needed. It also led to...
  • A failure to play e3, which is typical in this types of positions, restraining Black's idea of a ...f4 push. Around moves 3-4 could have been a good time to do it, but as late as move 12 it would have given me at least a slight plus, by neutralizing Black's pawn play on the kingside.
  • Failure to find the necessary defensive thread while under pressure. I at least understood that a focus on defense was necessary once Black played 12...f4, and was following the correct path with 16. Bf3. However, on move 18 I did not calculate correctly. Seeing in analysis how the king can be a defender (18. Kg2!), especially when the opposition lacks the minor pieces to dominate squares or sacrifice to open up the position, was enlightening.

Nc3 Nc6 3. Nf3 f5 4. d3 {this scores poorly in the database, around 40 percent. Better to challenge the center immediately with d4. It is still the second most popular move played, however, probably due to the reversed Sicilian type positions that arise.} Nf6 5. Rb1 $146 {not in the database at all! The idea is to get an accelerated version of the queenside b-pawn push going.} (5. g3 { is more consistent with White's previous move.}) 5... Be7 {a safe choice.} ( 5... e4 6. dxe4 fxe4 7. Nd4 $11) 6. g3 O-O 7. Bg2 d6 {we're now back in the database. Both White and Black have achieved standard-looking setups, although my path was a little wobbly.} 8. b4 {time to get the b-pawn rolling.} Qe8 { making space for the knight.} 9. b5 {it's not necessary to push this immediately. The threat remains and another move to build up pressure like Nd5 may be better. O-O also helps development.} Nd8 $11 {around here I was feeling good about my game, having pushed Black's knight around, but the engine is more objective. The position is equal, with White's queenside space advantage being offset by Black's coming play in the center and kingside.} 10. O-O Ne6 { understandably wanting to get the knight back into action.} (10... a6 $5 { is what the engines prefer, putting some pressure on White's advanced b-pawn.}) 11. a4 Qh5 {Black signals that he will ignore the queenside in favor of going all in on the kingside.} 12.

Bxg4 Qxg4 { this should be equal, but there is only one good defensive move and I fail to find it.} 18. f3 $2 {this was based on a miscalculation. When making pawn moves, it's important to understand the weakened squares they leave behind, in this case e3.} (18. Kg2 $5 {the king "steps up in the pocket" and covers both h3 and f3 effectively. With Black not having a light-square bishop, this is possible.} fxg3 19. Rb4 (19. hxg3 {also works, but is trickier for White.} Bh4 20. Qe1 Qd4 (20... Qxa4 21. Qb4 $11) 21.

I was too rattled to put up further resistance, however, thinking I was already lost. The main problem is that I lose far more than the exchange after Black's pin of the Rf2, due to the g3 pawn hanging.} (20. Rg2 { is the only move.} gxh2+ 21. Kh1 Bf4 22. Bc1 {keeps White in the game, although not happily.}) 20... Be3 $19 (20... Be3 21. Qf1 Qxg3+ 22. Qg2 Bxf2+ 23. Kh1 Qxg2+ 24. Kxg2 Bb6 $19) 0-1

Training quote of the day #26: Boris Gulko

From Lessons with a Grandmaster, by GM Boris Gulko and Dr. Joel R. Snead.
I like challenges, I like to struggle and fight against the best. That's very exciting to me. Also, I grew up (as did my generation in the USSR) believing that generally, reputations were not to be trusted. Of course, it is hard to be a fake in chess (compared to politics) because if you are weak you will simply lose. Perhaps some of this general belief persisted in the world of chess. The idea of not trusting reputations contrasted sharply with what I experienced when I first came to the United States. I found chess players to be much more polite; e.g. offering a draw to a higher rated player in better positions. We would never do that; we would want to beat them, even make them suffer.

Video completed: "Why You Should Always Think Before Taking a Draw" by Tatev Abrahamyan

"Why You Should Always Think Before Taking a Draw" is the fifth video in the new Chess.com series by Tatev Abrahamyan. It is shorter than the others, at around 7 minutes, which I think is appropriate for the topic. An opening quote summarizes its main idea nicely, in the context of thinking about what to do when a higher-rated player makes a draw offer, although I believe it applies to our general approach to the game as improving players:
We want to be able to play objective chess, rather than emotional chess...and be able to play the position, not so much our opponent.
In the first game example, taken from the Bundesliga where White has a 300-point rating deficit, White took a draw when there was essentially zero risk of losing and he had all the winning chances.  "Playing with zero risk against a strong player, it's something we have to do all the time [meaning every time]. We owe it to our position to actually play the game out." The second game is similar, with the Black player down 300+ points, but after the coming forced sequence being up a pawn and having all the better chances.

The third example acknowledges the role that time pressure can play in accepting a draw, but Abrahamyan argues that if you can play "easy" moves until a time control, you can then do deeper calculation once you have more time. In other words, don't try to calculate all the way to a win if that's not possible, rather take obvious (but with a tactics check!) ways to at least preserve your existing advantage. In this particular game, Black's king position was weak and White had some easy follow-up attacking moves that would not have let Black get any counterplay.

In each case, a contributing factor is the "visual" evaluation of the board, in which superficially the side offering a draw seems like they may have some counterchances or threats. The third game was a good example of this, in which Black had a passed pawn on d4. However, when concrete analysis shows there is no actual opportunity for your opponent to implement a threat, it is worth playing on. In this particular case, White could keep making threats against Black's permanently weak king. In another example from the first game, White could at any time just force a draw via perpetual check, so that provided a sufficient safety net to play for a win.

In addition to being simply good, objective chess, the principle of playing out a favorable position I think is one of the practical keys to advancing your chess strength (and rating). It helps build mental toughness - remember Fischer's motto "No draws!" - and there's also the simple fact that "you can't win if you don't play." Unfortunately time pressure does sometimes interfere with an objectively best decision, along with emotional pressure - but the latter is something which you put on yourself and is subjective, not objective.

I would therefore suggest mentally rejecting the idea of a draw - including offering one yourself - if the decision would be made on a purely emotional basis. I remember having to repeatedly fight down the impulse to hope/wish for a draw in my best game ever, and was very glad that I did so. Yes, losing is then a possibility, but once you accept that fact for each and every game, it makes it mentally easier to give yourself the chance to win more often.
