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

Annotated Game #308: A practical swindle

This next first-round tournament game was useful for my study of the Caro-Kann Exchange, which seems to be more popular lately (at least for the opponents I've been facing). If Black ignores his queenside counterplay for too long, as happens here, White can get some kingside momentum. After my opponent builds up what should be a winning attack, I decide to go all in on the counterplay for practical chances, aided by my opponent's time pressure. This pays off when I spot a key equalizing tactic, then hold on for the simplified endgame draw.

1.e4 c6 2.d4 d5 3.exd5 cxd5 4.Bd3 Nc6 5.c3 Nf6 6.h3 played to prevent the standard ...Bg4 development. g6 7.Nf3 Qc7 played to restrain White's Bf4 development. 7...Bf5 immediately is just as popular in the database. 8.0-0 Bf5 9.Re1 Bxd3 if White does not take on f5, which transforms the pawn structure and Black's strategy, then it is better to exchange bishops and play "normally" with subsequent development. 10.Qxd3 Bg7 11.Be3 0-0= Black has now equalized. 12.Nbd2 e6 although this creates some dark-square holes, the reinforcement of d5 is worth it. 13.g3 obviously looking to put the Be3 on a better diagonal. Nh5 the most played in the small database sample, as Black again plays to restrain Bf4. There is also the idea of sacrificing on g3, which White moves to prevent. 14.Kg2 now Black needs to come up with a middlegame plan. Rfd8 my thinking here was to clear f8 for a potential bishop maneuver and reinforce the d-pawn to possibly enable an ...e5 break, while maintaining flexibility for a queenside pawn advance. The engine is not impressed. 14...f5!? the point here is to immediately act on the kingside, where Black is temporarily stronger and controls f4. 15.Nf1 f4 16.Bd2 fxg3 17.fxg3 Rae8= White's pieces cannot easily further target the e-pawn, while Black will look to put additional heavy pieces on the f-file. 14...Rac8 is a more traditional approach, putting the rook immediately on the half-open file. 15.Nf1 played to give the bishop retreat squares, plus it reinforces g3. Rac8 16.Rad1 Ne7 a long think here about my plan. I eventually decided that the more obvious ...Na5 did not pay off. However, the engine disagrees. 16...Na5 intending to go to c4. 17.Bg5 perhaps I gave too much weight to this possibility, which is not really a problem for Black. 17.b3 Nc6= the knight has provoked a weakening of White's c-pawn, which is not critical but must be guarded, helping ensure equality. 17...Qxc3? 18.Qxc3 Rxc3 19.Bd2+- 17...Re8= with ...h6 and/or ...Nc4 coming. 17.Bc1 proactively moving the bishop away while reinforcing b2. Nf6 another long think here. The knight's only duty on h5 was preventing the bishop from going to f4, which I judged was keeping it too much out of play. 18.Bf4 Qa5 I spent a fair amount of time here as well, since the best square (and plan) for the queen is not obvious. 18...Qc4 is probably simplest (and best). 18...Qb6 19.a3 White by this point has a small edge, as I have no real counterplay and his pieces are somewhat better placed, with Ne5 and Bg5 available to increase pressure. Qb6 making a slightly annoying threat to the b-pawn that is easily parried, but also reinforcing the 6th rank. 20.Re2 Nc6?! reviving the ...Na5 idea, but this turns out to be a bit slow. 20...h6 20...Qa6!? I briefly considered this idea around here, which the engine considers as possibly best. 21.Qxa6 bxa6 22.Ne5 h6 the doubled a-pawns are a long-term weakness, but without the queen White has trouble exploiting them. 21.g4 preventing a return of the Nh5 and also pointing towards a kingside attack plan. Na5 22.Ne3 22.Ng3 looks more effective, also controlling e4. 22...Nc4 23.Nxc4 I felt fine after this exchange, which finally allows for some more active play. dxc4= 24.Qc2 Nd5 now I can hit the Bf4 from the other side. 25.Bg5 Bf6 I thought for a while here, since again there are several major options. 25...Re8= is the simplest response and good. 25...Qc6!? I actually briefly thought of this as a candidate move, but did not further pursue the calculations, partly due to fatigue at this point in the game. 26.Bxd8 Nf4+ 27.Kg3 Nxe2+ 28.Qxe2 Rxd8= would have essentially assured the draw. 26.Bc1 Qc7 with the obvious idea of ...Nf4. 27.Qe4 here I started getting too worried about White's kingside attack prospects. Getting queenside counterplay rolling with ...b5 or ...a5 is now the most active idea for Black. Qe7?! this essentially wastes a tempo and blocks use of the e7 square for other pieces. 28.Rh1 Qf8?! this makes it worse. I was too concerned about defending against imaginary mates on h7/h8 and thought about fianchettoing the queen. 28...Bg7 29.Ree1 b5? I did not calculate the defense properly after White's next move; this should have been played earlier. 29...h6 30.h4± a5 31.g5 this is the less effective option for prying open Black's kingside. 31.h5! 31...Bg7 32.h5+- forcing the opening of the h-file for White's pieces. Qe7?! not the best, but I am out of good moves here anyway. 33.hxg6 hxg6 34.Rh2 b4 objectively the queenside counterplay comes too slow, but I felt it was the best practical chance. My opponent was significantly lower on time at this point. 35.axb4 axb4 36.Bd2 bxc3 37.bxc3 Rb8 I was getting fairly low on time here myself, so did not fully examine other options. Again, the practical choice. 38.Ne5? now I felt much better, since I had spotted a tactical idea earlier on the long diagonal, which the knight had been blocking. 38.Reh1+- 38...Qb7 38...Rb2 was also possible here and a little better according to the engine, but I was not up for the necessary calculation of variations at this point. 39.Reh1 now the Nd5 can move with check to either e3 or f4, but I was not sure exactly how to execute the threat. Doing it immediately is best, according to the engine. Bxe5 now my opponent picks the wrong recapture, although I am still OK after Qxe5. 39...Ne3+! the Qe4 is now hanging and pinned, enabling the following tactical sequence. 40.Kf3 forced Nf1 I vaguely saw this idea but could not calculate further. 41.Rxf1 Bxe5 42.Qxb7 Rxb7= with a completely equal game after 43.dxe5 Rxd2 39...Nf4+ 40.Kf3 Nd5= 40.dxe5 Nf4+! 41.Kf3 Nh5= I spent a chunk of time here ensuring this move was fully safe and effective. 42.Be3 Rd3 43.Rh4 we were both low on time now, although I was still relatively better off. Rxc3 44.Qxb7 the correct decision to simplify, given White's worse king position. Rxb7 45.Rc1 Rxc1 46.Bxc1 Rb3+ 47.Ke2 c3 I correctly assessed that I had no actual winning chances, but wanted to stay active. 48.Rc4 Kf8 49.Kd3 Ke8 50.Rxc3 Rxc3+ 51.Kxc3 this is now fully drawn, but my opponent decided to try and press me in the BvN endgame. Due to White's pawn placement blocking his bishop's mobility and the outposts available to my knight, this is still a simple draw, however. Ng7 52.Kc4 Kd7 53.Kc5 Nf5 54.Bd2 Ne7 55.Ba5 Nd5 56.Bd2 Ne7 57.Kb6 Nd5+ 58.Kb7 Nc7 59.Be3 Nd5 60.Bd2 ½–½

Book Completed: Bologan's Caro-Kann - A Modern Repertoire for Black


I recently completed Bologan's Caro-Kann: A Modern Repertoire for Black (New In Chess, 2018) by GM Victor Bologan; sample pages containing the variation choices can be found at the above link. As is normally the case with repertoire books, it doesn't fully match up with my personal choices of opening variations, but I found it quite useful for new insights into general position-types, as well as fleshing out certain parts of my Caro-Kann repertoire. It is worth mentioning that this is not a "pure" repertoire book, as he does offer multiple choices for Black responses fairly frequently.

My main intention was to focus on typical plans and how to play the position-types reached, which was at least partially satisfied. Bologan is a Caro-Kann tournament player himself and this comes through in his comments and choices based on experience, not just pure analysis. As with any reference work, reviewing the lines using an up-to-date games database and engine in your own opening repertoire database is still necessary. This also makes the learning process an engaging one, rather than simply accepting the author's judgments on everything. It also helps to stimulate your own thinking and allows you to make your own personal choices, based on what you can understand in a position and is best suited for your style of play.

Here are some comments on his treatment of different parts of the Caro-Kann, from the point of view of an improving player:

Part I - Minor Lines: 

  • This was the first treatment of 2. Ne2 that I had seen, so it was enlightening to examine the ideas involved. Essentially Black treats it very similarly as the Advance Variation with 3...c5, but has to watch out for different ideas involving Ne2-d4, as well as Ne2-g3. On the other hand, the white knight's absence from f3 helps Black target the advanced e-pawn. Black has to be careful to not be too aggressive, but is fine in all variations.
  • Bologan has the most detailed treatment of the King's Indian Attack (KIA) that I've seen, with detailed recommended lines against different White choices, including earlier (move 5) than normal. In some cases he provides useful explanations and insights into his repertoire choices for Black; in others, not so much. This is generally the case throughout the book. For example, I would have liked more discussion about a locked vs. mobile center, and the question for Black about when and where to develop the light-square bishop.
  • There is no discussion about the White setup with Nf3 and d2-d3, which can be reached in the typical KIA move-order after 3. Nf3. This is likely due to the fact it did not become more popular until after the book was released.
  • For the Fantasy Variation, Bologan recommends the solid 3...e6, which I don't play. His treatment of it seems comprehensive, though.
  • The Two Knights Variation is included in this section and he shows the lines with 3...Bg4, which are reliable for Black.
  • Although these are treated as "minor" lines, Bologan presents them in more depth than introductory books and the preparation he shows will be valuable for Black at the Class level, where especially the Fantasy, Two Knights and KIA are all relatively popular.
Part II - The Steiner System, Panov Attack, Exchange Variation
  • I don't play his recommendations for the first two variations, but I found his analysis of the Exchange Variation again to be the best for Black that I have encountered. This is important, given it is certainly popular at the Class level - I've personally encountered it recently - and seems to have had at least a minor resurgence in master games.
Part III - Classical System
  • This part was a mixed bag for me, as there are a number of sidelines in the so-called Main Line Classical (4...Bf5). Most of his recommendations up to move 7 were very useful for me, and he treats in-depth the setups involving 6. N1e2 and 6. Bc4, as well as seriously examining the early f2-f4 ideas for White on moves 6 and 7, which is often under-analyzed or not treated in Caro-Kann references.
  • I don't play the standard main line starting from move 8, and Bologan seems to like castling queenside versus kingside for Black, which is not my preference.
Part IV - Advance (Closed) Variation (with 3...Bf5)
  • I don't play this.
Part V - Positions for Solving
  • Bologan at the end presents 40 positions drawn from tournament (including ICCF) play, for solving from both the White and Black perspectives. I found this useful for boosting pattern recognition of typical tactical and positional ideas in the Caro-Kann, including situations with opposite-side castling, ideas of undermining of White's center with pawn breaks (...b5, ...c5 and ...f6) and identifying vulnerabilities allowing White to sacrifice successfully on e6 or g6/h6.
