| Mar-14-09 | | Hesam7: <<29...Bf4> 30 Ra6 Bxg5 holds no prospects, so White plays <30 Ne6>. Here, it’s important that Black select the right square for his bishop retreat. After <30...Bh6!>, the bishop controls the e3-square, which is important in the variation 31 Re8 Qf3 32 Nf8+ Kf7–+. On <31 Nf8+>, Black does not play 31...Kf6 32 d5!? =, when the queen is ready to check on d4, but <31...Kf7!>

All attempts to create counterplay against the black king fail even to create perpetual check. 32 Nd7 Qh3 33 Ne5+ Ke7 34 Ra7+ Kd6! (but not 34...Ke6? 35 d5+! cd 36 Ra6+, with a draw) 35 Nf7+ Kd5 36 Rd7+ (36 c4+ bc 37 Ra5+ Ke6–+) 36...Ke6 37 d5+ Kxd7 38 dc+ Ke8 39 Qd7+ Kf8 40 Qd8+ Kxf7 41 Qd7+ Kg6 42 Qe8+ Kg5–+. 32 Ra7+ Kxf8 44 c4 Qf3 34 Qa3+ Kg8! 35 Ra8+ Kf7 36 Qf8+ Kg6 37 Qe8+ Kg5 38 Qe7+ Kh5 39 Qh4+ Kg6–+. 32 Qb1!? Nxf1! (it’s drawn after 32...Qf3 33 Qa2+ Nc4! 34 Nd7 Kg6! or 34 Qa7+ Re7) 33 Qa2+ (nothing changes after 33 Kxf1 Qf3 34 Qa2+ Kf6) 33...Kf6 34 Nxh7+ (34 Nd7+ Kg5) 34...Kg6 35 Nf8+ Kg5 36 h4+ Kg4 37 Kxf1 Kh3–+. We can conclude that Black would have won, had he played 29...Bf4!! 30 Ne6 Bh6!, which means that, instead of 26 Ra8+?!, White should have played 26 Ne5!, and settled for a roughly equal position. This winning plan for Black was not mentioned in previous commentaries, so the game never received a proper assessment.> -- Mark Dvoretsky For the full commentary see: http://www.chesscafe.com/dvoretsky/... |
