Feb-22-11 | | paul1959: Sorry , but White could go have got the better of it here by playing 41 h4 and pushing the h pawn (From Keene and Levy book on the Olympiad). V.K. had a winning position but bungled things up in time trouble , his nemesis. By the way, in the same Olympiad ,he was badly beaten by Bilek and was probably losing to Rubinetti at the time the Argentines struck a deal for a 2-2 tie with the Soviets. |

 | | perfidious: Korchnoi actually lost this game on time at the dreaded 40th move, but no arbiter was present to note this, according to Tal in various sources. Wade notes, amongst other things, that 32....Ke7 is a grave error in a winning position, suggesting 32....Ke8, intending to meet either 33.Rg6 or 33.Rg7 with 33....Rb7. In the opening, 8.Ne2 was improved upon in the following game: Adorjan vs J L Watson, 1981. |

May-04-11 | | lost in space: The first who was lost was Silvino after 14. Bc1??
14. Bc1 hxg4 15. Bxg4 f5! 16. exf6 gxf6 17. Qd3 Rg8
 click for larger viewand the Bg4 is finally gone,. I wonder why Korchnoi - normally a killer" have not found it. |

 | | perfidious: <lost in space> From the diagram, Wade gives 18.h3 f5 19.Ng5 fxg4 20.Qh7 Rg7 21.Qh5+ with the evaluation 'unclear'. White has attacking chances, but are they really enough for the piece? Somehow, I doubt it. |

What's the point behind 17. Qd3 in your line above? For example, at first glance after 15... f5 16. exf6 gxf6 <17. Kg2> Rg8 18. Kh3 or 17. Kg2 f5 18. Bh3 would save the bishop. Am I wrong? |

May-04-11 | | lost in space: Well, seems that Wade and I agree on something - even though I don't know him and that I am not aware that he was mentioning this line. It seems this is the key position of the line (from ym last diagram: 18.h3 f5 19.Ng5 fxg4 20.Qh7  click for larger viewI think the best line here starts with 20...Ne7 21. Qf7+ Kd8 and I don't see a promising continuation for White. Seems to be a significant advantage Black.  click for larger view
I guess 20...Rg7 is lees good: 21. Qh5+ Kd7 22. Nxe6! Kxe6 23. f5+ Kd7 26 f6 with significant advantage white.  click for larger view
So doubled edged as you have to find the right continuation, but as long as we can not find a refutation of 20..Ne7 I stay with my statement that white was lost first after 14. Bc1 |

What's the point behind 17. Qd3 in your line above? For example, at first glance after 15... f5 16. exf6 gxf6 <17. Kg2> Rg8 18. Kh3 or 17. Kg2 f5 18. Bh3 would save the bishop. Am I wrong?> The idea behind Qd3 is to be able to penetrate into Black's position with Qh7. As you can see from the lines in my post above this is excellent if Black plays the weak move 20. Rg7. Now to your idea 17. Kg2 (instead of 17. Qd3).
I have not thought about it, but I think Kg2 is a wonderful idea, but not good enough (at least I think so): After 15. Bxg4 f5! 16. exf6 gxf6 17. Kg2 Rg8 18. Kh3
 click for larger viewyou seems to be right that White can avoid to lose the bishop. I think from here best play starts with 18...Qc7! and there will be a lot of different ways how White and Black can play. The general idea of Black is to activate his queen on the king side, e.g. 19. Bh5+ Kd8 20. Nh4 Qh7 21. Ng3 e5+ (impossible to not play this move for a human) 22. Kg2 exd4
 click for larger viewVery complicated, but I am sure better for Black. |

After 15. Bxg4 f5 16. exf6 gxf6 17. Kg2 Rg8 18. Kh3 Qc7, White can try covering the h7 square e.g. 19. Qd3 f5 20. Bh5+ Kd8 21. Ng5. Looks like there's a long game ahead. |

After 15. Bxg4 f5 16. exf6 gxf6 17. Kg2 Rg8 18. Kh3 Qc7, White can try covering the h7 square e.g. 19. Qd3> (snip) click for larger viewI guess Black has 2 option in this poition, both leading to something like a forced win: 19....Rxg4 20. Kxg4 Qg7+ 21. Ng5 (other moves like Kh4 or Kh3 are even worse) 21...fxg5 22. Kf3 e5
 click for larger viewor - (starting from the first diagram in this post)
19...e5 20. f5 (20. Bxc8 Qxc8+ is lost directly) 20...e4 21. Qd1 Rxg4 22. Kxg4 Qg7 and also here it is Black to win.  click for larger view |

You're right, my <Qd3> suggestion is a loser. And the line you posted earlier also seems pretty convincing. The maneuver with Kg2 and Kh3 to rescue the bishop looks too dangerous for White.After 15...f5 16. exf6 gxf6, let's look at other tries to save White's stranded bishop. 17. Ng3 seems to save the Bishop but then ...Qxc3 and White's pawn chain collapses. 17. Nd2 fails to 17...Ne3 18. Nb3 Nxd1 19. Nxa5 Nxa5 20. Rxd1 Rg8, and the bishop falls after all. So, looks like you're right up to the conclusion <as long as we can not find a refutation of 20..Ne7 I stay with my statement that white was lost> |
