|Jan-16-11|| ||mig26: Be5!! and the knight canīt stop the pawn
81. Na3 f5 82. Nc4 Bd4 83. Nd6 f4 84. Nf5 f3 85. Ng3 f2
86. Nf1 Be3 87. Ng3 Bf4 88. Nf1 Ke2
|Jan-16-11|| ||tamar: Looks to me that 64 Nd5 would have led to a draw since 64...Kg6 65 Ne7+ and Nc6 picks off the a pawn.|
|Jan-16-11|| ||Stonehenge: 64.Nd5 Kg6 65.Ne7+ Kg5 66.Nc6 Kg4 67.Nxa5 Kxg3. I'd rather have black here.|
|Jan-16-11|| ||rilkefan: Why doesn't White go for the draw with 36.Nf5? He's got 4(!) pawn islands vs 2 and nothing to compensate except phantom pressure on h6/g5, far as I can tell.|

But how do you win against 68 Nc6
68...Kf4 69 Nxb4 is = acc to tablebase

68...Bf8 69 e5 f5 70 e6 and the knight looks to be in time to stop the f pawn.
|Jan-16-11|| ||Stonehenge: Yes, I was too lazy to look at the tablebases. It's a draw. Sorry.|
|Jan-16-11|| ||Fanques Fair: Rilkefan, actually I donīt understand why hasnīt White played 37-Rxf7, as he was pressing this pawn for a long time. I donīt see any couter-threat by black, what was he afraid of ?
Ok now I see : 37-..., Nd6, gaining the c4 pawn ...|
|Jan-16-11|| ||perfidious: <rilkefan> Before I read any of the kibitzing, the same thought went through my mind-White has no good reason not to claim a draw here.|
|Jan-16-11|| ||HeMateMe: Wow, the power of Bishop over Knight in the endgame, huh? I wonder if Nepo played this perfectly, or did Wang have missed drawing chances, as the board cleared?|
|Jan-16-11|| ||percyblakeney: Wang Hao could have taken the draw with 36. Nf5, but in time trouble, with one hour less on the clock, he decided to play on and it didn't turn out to be a good decision.|
|Jan-16-11|| ||Eyal: <Wang Hao could have taken the draw with 36. Nf5>|
At this point, it's rather funny to look at the comments on chessok about this game (http://chessok.com/broadcast/?key=w...) - when they want to suggest a slightly better move, they have this polite phrase "An interesting alternative is..." (another such phrase that they use is "Novelty of doubtful advantage" when someone blunders in the opening); so the comment on 36.Kc2 is <An interesting alternative is 36.Nf5>.
|Jan-16-11|| ||Eyal: Wasn't the decisive mistake 78.Nb1 - giving up the e4 pawn, with the knight then being cut off by 79...Kd3! - rather than 64.Kb3? I don't see how Black is winning if White plays <78.Kd3> - basically, he just has to be careful to counter ...Kf2 by Black with Kd2, so as not to allow ...Ke1.|
|Jan-16-11|| ||HeMateMe: What do the 'Bots say?|
|Jan-16-11|| ||Penguincw: I personally choose this to be the best game for Round 2 from this tournament.|
|Jan-16-11|| ||Eyal: Yeah, I see that Shipov in his audio summing-up of round 2 (http://www.crestbook.com/files/Wijk...) also points out 78.Kd3! (78...Be5 79.Nb1=) as drawing for White.|
|Jan-16-11|| ||twinlark: When I first played this game through, I found giving away the e-pawn to be incomprehensible...first he removes one defender with <77. Kc2> then the other with <78. Nb1>, the e-pawn is taken, and then he resigns soon after. |
Hao must have been hallucinating that his Knight was enough to defend against the last Black pawn.
|Jan-17-11|| ||Eyal: Btw, an attempt to zugzwang White after 78.Kd3 by 78...Bd6 79.Nb1 Bb4 wouldn't work, because White has 80.Kc4! - abandoning the defence of e4 but attacking the bishop, and 80...Kxe4 81.Kxb4 is a draw.|
|Jan-17-11|| ||Albertan: I have analyzed this game using Deep Rybka 4x64 on my quad core computer and posted this analysis to my blog. Deep Rybka 4 analyzed the game for 2 hours in analysis mode and found exactly where Wang Hao lost this game. A direct link to this analysis on my blog is:
I hope you drop by and play through the game,even though it is a long one!
|Jan-20-11|| ||Dionysius: Very kind of you Albertan, but for me the game is more about the interaction between the players at the board. I enjoy their triumphs and forgive their errors, and for me, that depth of computer analysis would violate the artistic and competitive endeavour. I'll pass, while asppreciating your kind thought.|
