Allentown Spring Open (1), Apr 11, 1987
1.e4 e6 2.d4 d5 3.e5 c5 4.Nf3 cxd4 5.Nxd4 5.Bd3!? follows old Nimzovichian concepts. 5...Nc6 6.Nxc6 bxc6 7.Bd3 Qc7 This strikes me as an unattractive way to play for White; Black has a good chunk of the center and can maneuver around the e5 wedge. 8.Qe2 Ne7 9.0-0 Ng6 The knight is very good here, harassing e5 and discouraging the development Nd2-f3 because of ..Nf4. 10.Re1 [10.f4!?] 10...Be7?! 10...c5, grabbing space, seems logical. 11.c4! Ba6!? 12.a3?! Ambitious, but 12.b3! is more logical, planning Nc3, Bd2 and Rac1, and making sure the a6-bishop bites on granite. Black would have to change plans with ..d4 and ..c5. 12...0-0 13.f4 Rfe8?! Wasting time. Nowadays, I would have moved the other rook here, or else just gone ..f6 right away.
At least I had the right general ideas and was trying to play according to the demands of the position. 14.Nc3 f6 15.b4 fxe5 16.fxe5 Rf8 17.Bxg6?! White doesn't play according to the demands of the position, and Black's pieces jump to life, especially the unopposed light-squared bishop and the Rf8. 17.Qg4 Qd7 18.b5!? (not 18.Bxg6? hxg6 19.Qxg6 Bxc4) is the most ambitious way to punish Black, but 18...Bb7 gives Black good counterplay against White's loose position. 17.Qh5!? is also worth a look. 17...hxg6 18.Qg4 Bxc4 The combination of these two pieces points menacingly towards a mate on f1. (18...Rf5!? is ambitious.) 19.Qxe6+ Kh7 20.Bd2?! 20.Qh3+! would sensibly force a draw: 20...Kg8 21.Qe6+ and now 21...Rf7?! 22.Qxg6 Raf8 (22...Qxe5?? 23.Qxf7+) 23.Bg5 Bxg5 24.Qxg5 Qb6+ 25.Kh1 Qf2 26.h3 is not a good gamble for Black, especially
given the difference of ratings. 20...Rf5! The queen is cut off; Black is taking over. 21.Re3 Raf8 22.g4? A serious weakening. 22.Rh3+ Rh5 23.Rxh5+ (23.Rg3?! Qxe5! [As usual a loose center is retribution for a premature flank attack] 24.Qxg6+ Kh8 is very good for Black; for example, 25.Re1?? loses to ..Qxe1+ etc. I will never forget my opponent's frustration with this position in the post-mortem.) 23...gxh5 24.Be3 (Not 24.Ne4? Qb6+ 25.Kh1 Qd4!) is necessary, keeping White in the game. 22...Rf3 23.Rxf3 It is very hard to give good advice anymore. [23.Rae1 Bh4!] 23...Rxf3 The threat ..Qb6+ looms, and White is busted. 24.Na4 [24.Ne4 Bd3!] 24...Bb5 25.Nc5 Bxc5+ 26.bxc5 Qd8 The addition of the Black queen is more than White's position can afford, but there is
nothing to be done. Note again the great power of Black's bishop and rook. 27.g5 Qf8 28.h4 [28.Qg4 Rf1+ 29.Kg2 Qf2+ 30.Kh3 Rxa1] 28...Rg3+ 0-1
