Instant Gratification

Benefits of Study

Studying master games brings long-term benefits to chess players who are ambitious to improve their play. Occasionally, study also brings instant gratification. Yesterday, I had a moment of the latter. After spending the better part of my study time the past week studying Karpov -- Korchnoi, m2 (1974), I was able to apply a lesson from this game in my own online blitz play. In the end, however, I blundered, giving away the game. My opponent failed to seize the win, answering my blunder with one of his own.

Game losing blunders are in the nature of blitz. Study, however, facilitates reaching a decisive advantage after eighteen moves played in under one minute.

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.Be3 Bg7 7.f3 0–0 8.Bc4 Nc6 9.Qd2 Bd7 10.0–0–0 Rc8 11.Bb3 Ne5 12.h4

Via a different move order, we have reached the same position as in my reference game.

Black to move

12...h5 Black prevents White's thematic pawn sacrifice and action along the h-file.

13.Bg5 Nc4 14.Bxc4 Rxc4 15.Nde2 a5N

15...Qa5 16.Kb1 Rfc8 17.Bxf6 exf6 18.Nd5 Qd8 19.c3 b5 20.Ne3 Bh6 21.Qxd6 Bxe3 22.Qxd7 Qa5 23.Rd5 a6 24.Rhd1 R4c7 25.Qd6 Rc6 26.Qe7 Bc5 27.Rd8+ Kg7 28.Qe8 Rxd8 29.Rxd8 Qxd8 30.Qxd8 Bf2 31.g3 b4 32.Qd5 Rc5 33.Qd3 a5 34.c4 g5 35.Nd4 Re5 36.Nf5+ Kg6 37.Qd8 Rxf5 38.exf5+ 1–0 Suder,R (2222)-Dukaczewski,P (2336)/Poznan 2007/EXT 2011

White to move

Here I spotted a tactic that I remembered from Mikhail Botvinnik's annotations in Chess Informant 18/433. The position differs from Karpov -- Korchnoi, but the vulnerability of the bishop on e7 is the same.

16.e5! dxe5?

16...Nh7 17.exd6 Nxg5 18.dxe7 Qxe7 19.Qxd7 Qe3+ 20.Qd2 Qxd2+ 21.Rxd2 Ne6±

17.Bxf6 Bxf6 18.Qxd7+- Qb6 19.Nd5

19.Ne4 would be better

Black to move

19...Qc5

19...Qf2 20.Nec3

20.Nxf6+ exf6 21.c3

I should have played 21.Nc3

21...b5 

21...Qf2 22.Qd3 does not lead to advantage for Black, but is better than in the game.

22.Qd5 Qe3+ 23.Qd2 Qc5 24.Ng3 b4 25.Ne4 bxc3

White to move

26.bxc3 Qa3+ 27.Kb1

27.Qb2 is better

27...Rb8+ 28.Ka1 f5 29.Nf6+ Kg7 30.Nd5 Rd8 31.Rb1

31.Qe2

31...Rc5

White to move

32.Rb3??

32.c4+- was the only move

32...Qa4 33.Nb6 Qxa2+??

33...Qxb3–+

34.Qxa2 1–0
