May-21-06 | | alexandrovm: Pono seems to be in some trouble now, black's double attack with the queen over the rook and a check over the king is dificult to meet now... |
|
May-21-06 | | qjuice14: Anand just missed an much quicker win.. 37....gxf2+ was a blunder.. 37...g2 wins much quicker,, one more oversight like that and he might allow Ponomariov a draw |
|
May-21-06 | | Open Defence: yeah i was trying to work out why Anand did not play g2+ |
|
May-21-06 | | Dionyseus: This is a tablebase draw. If queens go off the board, white simply has to trade one of the pieces to draw. |
|
May-21-06 | | themadhair: <Dionyseus>Not so. We may see a B+N mate. |
|
May-21-06 | | chessbond: B+N mate...is that possible and has that happend anytime?? |
|
May-21-06 | | qjuice14: or even simpler and more probable a simple promotion will do |
|

 | | Peligroso Patzer: The current position (after 49. ... Nf7) must be winning for Black. Even if White can manage to exchange his light-squared Bishop for the Knight, the opposite-colored Bishop ending would probably still be winning, since Black has two passers. |
|
May-21-06 | | knightpower: yes B+N is a standard mate given in many text books ..... havent seen any game though |
|
May-21-06 | | alexandrovm: <Dionyseus: This is a tablebase draw. If queens go off the board, white simply has to trade one of the pieces to draw.> really, I wasn't aware of that piece of theory. The pair of bishops is dificult to meet in a clean board, but I was thinking that black's two extra pieces would do the job for Anand here, to win the game... |
|
May-21-06 | | themadhair: Game using B+N to mate Xu Jun vs Wang Yaoyao, 1997 |
|
May-21-06 | | qjuice14: 52....Ne4+ anands 2nd endgame blunder... Pono has the draw now with precise play.. I knew one more oversight by anand would allow the draw. |
|
May-21-06 | | Dionyseus: Anyone doubting that this is a tablebase draw can go to broadcast room in the Playchess server, i put up a broadcast named "Anand endgame" where I put up several variations proving that this endgame is drawn. |
|

 | | Peligroso Patzer: Well, apparently the GMs assess this opposite-colored Bishop ending as drawn (the official result that has just been posted). Guess my earlier post was off-the-mark. |
|
May-21-06 | | qjuice14: <Dionyseus> The end position is obviously a table draw. But as soon as the queens went off the board Black had a winning advantage. Though it seems apparent from this tournament that Anand needs a brushup on endgame play. |
|
May-21-06 | | Dionyseus: <qjuice14> Even if he had not played 52...Ne4+ it is still a draw. |
|
May-21-06 | | alexandrovm: opposite colored bishops now... |
|
May-21-06 | | alexandrovm: <Dionyseus: <qjuice14> Even if he had not played 52...Ne4+ it is still a draw.> we share some interests, see you around my friend... |
|
May-21-06 | | themadhair: <Dionyseus><Anyone doubting that this is a tablebase draw can go to broadcast room in the Playchess server, i put up a broadcast named "Anand endgame" where I put up several variations proving that this endgame is drawn.>I don't see the draw but I do believe you. I don't have a playchess account - is it possible for you to reproduce some of you analysis here? |
|
May-21-06 | | hitman84: <Dionyseus><"Anand endgame" > Very Nice.Thanks! |
|
May-21-06 | | notyetagm: <roughstuff: why is the Pono-Anand game a draw?surely anand can promote one pawn..I donĀ“t get it..is he tired or what?> This is an <opposite-colored bishop> endgame after 53 ... ♗xe4. White will setup a <dark-squared blockade> on the f4- and h4- squares, using his excellently placed g3-king. White will play 54 ♗d2, putting his bishop on the c1-h6 diagonal and gaining control of the f4- and g5-squares. Once he has done that, he will then simply move his dark-squared bishop along this diagonal forever (♗c1-♗e3-♗f4-♗d2-♗c1-♗f4-etc.). <Black will then be unable to advance his pawns safely to f4 and h4.> If the Black f-pawn ever goes to f4 or the Black h-pawn ever goes to h4, White will simply capture it. Hence Black cannot promote either of his pawns because he has so little control of the <dark squares>, f4 and h4 in particular. Chess is not checkers so Black cannot play ...f5, ... f3, and ... f1=♕, for example, bypassing the dark squares f4 and f2 which White firmly controls. <Play the position out against a chess computer.> You will quickyly understand what I just wrote. This is the exact same question I had when I watched the Kasparov-Kramnik match back in 2000. In one of the games Kasparov was up by two pawns in an opp-colored bishop ending and I was shocked when they agreed to a draw. I could not understand why it was a draw. Now I do. |
|
May-21-06 | | Confuse: thanks <notyetagm>, i was just about to ask the same question! this is a nice trick to remember for later : ). poor anand though, after all topalov with two ponds up knocked bacrot out convincingly. again, too bad for anand. well played by both |
|
May-21-06 | | s4life: B+N mate:
Ljubojevic vs Judit Polgar, 1994
And Judit was playing blind! |
|
May-22-06 | | Manic: Chessbase: <. Anand should have equaled him but he was, shockingly for the legendarily speedy star, in time trouble again against Ponomariov. This caused him to miss a clear win with 37..g2! and the draw left him in third place.>
Guess that explains why anand drew and probably why he played Ne4+ in the first place, so to avoid losing on time. |
|
May-23-06 | | Ulhumbrus: Mark Crowther gives a variation at the end of which Anand wins by a fork: 37...g2! ( instead of 37...gxf2) 38 Kxg2 Qxd5+ 39 f3 ( Now this is forced,for this is the first difference : On 39 Kg3 Qg5+ 40 Kh3 Qh4+ is mate!) 39... Nf4+ 40 Kg3 ( White has to play this, for 40 Kf2 leads to a king hunt: 40 ...Qd2+ 41 Kg3 Nh5+! 42 Kg3 Qf4+! 43 Kxh5 Bxf3+ wins. After 40 Kg3 it is not obvious immediately that the K can be driven fatally to the point e3, which however it can) 40...Qg5+ 41 Kf2 Qh4+ 42 Ke3 Nd5+ (In order to avoid getting mated the White King has to walk into this fork) So Anand missed a win apparently , a win taking the form of a fork at the end of one variation. |
