Annotated Game #363: Opening knowledge matters

As in the previous Annotated Game #362, my lack of familiarity with the opening - this time as Black in the Dutch vs. a London System - is a fundamental flaw in my play. As I continue to learn and absorb lessons in my new openings (Colle System as White, Dutch as Black), the dynamic of "learn by losing" is certainly evident. In this second-round tournament game we can see a lack of understanding over where best to place Black's pieces repeatedly undermining my position, along with a lack of awareness of potential opportunities early in the opening (6...g5!) While tightening up on my thinking process obviously would help - that is always the case - there has been a curious and notable difference between confidently knowing where my pieces should go and what structures are good in an opening, and flailing around in new territory where my assumptions about what "looks good" are not necessarily valid. This is why the process of analyzing your own games is so important, to make sure there is a feedback loop that is identified and then implemented for long-term learning.

Bf4 Nf6 3. e3 {a London System move-order that defers placing the knights.} e6 4. Bd3 b6 (4... Be7 {the text move seems fine, and is the most played, but developing the dark-square bishop first scores better in the database.}) 5. Ne2 {a rare move. This does not seem like the best square for the knight, with no good squares to move to next.} Bb7 $11 6. O-O Be7 $6 {this seems like a normal developing move, but is not active enough and gives White a pass for his relatively lackadaisical opening play.} (6... g5 $1 {this did not occur to me, for probably obvious reasons - sacrificing the g-pawn does not immediately look like a profitable idea. However, the engine has no such prejudice and identifies White as the one who would lose from the opening of the g-file. A characteristic of the position, given a Bb7 with a clear view of g2.} 7. Bxg5 (7. Be5 Nc6 $17) (7. Bg3 h5 8. h4 Ng4 $17) 7... Rg8 $19 {with a devastating pin.}) 7. Nd2 O-O {now the ...g5 idea does not have as much bite, with the Nd2 available for kingside support.} 8. h3 $14 {clearing h2 for a bishop retreat, if needed.} d6 {I had better options than this slow, stereotyped move.} (8... Bd6 $5 {looks strange, but after the exchange of bishops - White's is certainly better than Black's, so it makes sense - the doubled d-pawn would perform a useful function for Black. White has at most only a slight advantage.} 9. Bxd6 cxd6 $14 {followed by ...Nc6 and Black has a comfortable game.}) (8... c5 {would immediately challenge White in the center.}) 9. c4 Qe8 {a standard developing move for the queen, looking for a more useful diagonal (e8-h5).} (9... c5 $5 10. d5 exd5 11. Bxf5 dxc4 12. Nxc4 d5 13. Ne5 Qe8 $14) 10. Qc2 {while not an immediate problem, this move cuts off the Bd3's retreat and could cause problems if White is not careful.} Nbd7 $6 {"long think, wrong think" here. The knight does better on c6 in most cases.} (10... Nc6 {here it threatens to go to b4 and force an exchange of White's light-square bishop, as well as support e6-e5.} 11. a3 $2 e5 $1 $17 {with the threat to go to e4 and win the Bd3.}) (10... Qg6 $11 {would be a natural follow-up to the previous move, placing the queen on the g-file and controlling e4.}) 11. Nf3 h6 $6 {this ends up being weakening and missing several other good ideas.} (11... Kh8 {a common prophylactic move to get the king off the g8-a2 diagonal and clear g8 for a rook.} 12. Ng5 $6 {is not good because e6 is tactically protected.} e5 13. Ne6 $2 e4 $1) (11... Bxf3 {I considered, but did not want to give up my lovely-looking bishop. However, the structural damage inflicted would be worth it.} 12. gxf3 Kh8 $11 {renewing the idea of playing ...g5}) (11... Qg6) 12. Bh2 {smartly withdrawing the bishop in advance. This now leaves f4 open for the knight.} g5 $2 {too slow; piece activity is what is needed. White now takes advantage of my clogged center.} (12... Ne4 {and if} 13. Nf4 Qf7 $14) 13. d5 $1 $16 {I only appreciated the strength of this move after it was played, not having adequately considered it before, just vaguely assuming an exchange would be fine. Unfortunately I do not have enough pieces actively playing - a rook on c8 would be nice now, for example, to cover the c-file weakness.} Nc5 {it is best to counterattack, and I play accurately through the next sequence, but this is not enough for the defense.} 14. Nfd4 $1 {nicely using control of the center to further target my weaknesses, in this case e6.} e5 15. Bxf5 $1 {another strong follow-up; sacrificing the Nd4 had not occurred to me as a possibility. There is no immediate knockout tactically, but White has two pawns for the piece and should have a dominating attack.} (15. Nxf5 e4 $14) 15... exd4 16. exd4 {the lesser option, leaving the Ne2 out of the attack for longer.} (16. Nxd4 $1 $18) 16... Ncd7 17. Ng3 $6 (17. f4 $16 {gets on with the attack by exchanging on g5 and opening the f-file.}) 17... Kg7 $2 {wrong square. I was mistakenly fixated on trying to cover g6, but the king is too vulnerable here.} (17... Kh8 $1 $14 {solves most of Black's problems, tucking the king in the corner and making g8 available for a piece.}) 18. Rae1 {now White's attack largely plays itself.} Bc8 $6 {trying to oppose the Bf5, but unfortunately this is too slow.} (18... Ng8 {this is better immediately. I could not decide between this and the text move after a long think, so decided to play the text move to (sort of) activate the bishop.}) 19. f4 $18 {now White is fully in control.} Ng8 {best but still losing.} 20. fxg5 {good enough to continue the attack.} (20. Be6 $18) 20... hxg5 21. Qe2 $6 Ndf6 $2 {I was eager to play this - visually it looks like the knight is riding to the rescue while the Bc8 is activated - but now there is a winning forcing sequence after White's next move, which I did not sufficiently check, thinking it would be a great thing to eliminate the Bf5. Unfortunately, it is replaced by an even stronger knight on the square.} (21... Kh8 $1 $16 {this at first glance looks terrible, with all my pieces backed up in a jumble, but White has no knockout blows.}) 22. Bxc8 $1 $18 Rxc8 23. Nf5+ Kg6 $2 {all moves lose, this one does it faster.} (23... Kh8 24. Nxe7 Nxe7 25. Qxe7 Qxe7 26. Rxe7 $18 {and White has a winning endgame.}) 24. Qd3 Kf7 25. Nxd6+ cxd6 26. Qh7# 1-0
