Kibitzer's Corner
Jan-28-06  bane77: What a terrible performance from two top 10 players. White's 21.Ndb1 just doesn't make sense. Logical move is 21.Rc1. a7 pawn is poisoned, but the position is already difficult to hold. Then after 23.Rxd3 white is lost, better was 23.Bxe5. Then, 24.Rd1 is forced, the threat is 24...Nc5 (the queen is trapped). the game continues with
24.Rd1 b4 25.e5 (if 25.Ne2 Nc5)
White is lost, but black returns the favour and cannot win the game with piece ahead. The fastest way to win the game for black was 27...fxg3! White cannot take the knight because of 28...gxf2 and his position is falling apart. So, 27...fxg3! 28.hxg3 Ng4 29.Qa4 Bxc3 30.Rxc3 c5! destroying the white pawns in center and the game is over. Awful game.
Jan-28-06  Ybrevo: <bane77> You are right about the quality of the moves, but you could also look at it in another way: This game turned out to be more of a boxing-fight than an aesthetic gem of chess. Obviously Gelfand went for an easy draw around move 15. After a long think Ivanchuk played 16. - Re8 instead of taking the repetition. I will really give him credit for that, and the fact that he could not convert the advantage to a win is just what happens in live chess sometimes. Maybe time-trouble or an error in calculation? I still think it is better than a "perfect" draw in 15 moves.
Jan-28-06  Djuandemarco: 40 Qc4?? Qxc4??(40...f3+, 0-1)

Probably time trouble

Jan-28-06  AlexandraThess: Great defence by Boris Gelfand!
Jan-29-06  MarvinTsai: <Djuandemarco> I'm thinking of your line. Maybe 40..f3+ 41 Qa8 41..Qc6 42 Qxc6 Rxc6 43 Nd4
41..Rc6 42 Qxc6 Qxc6 43 Nd4
41..d5 42 Kxd5 Qxd5 43 Rxd5 Rxc1 destroy white's connected center pawns and exchange the tough bishop in the endgame. Is this right? If so, it's really a painful miss!
Jan-30-06  alefromitaly: That's a good tactical exercise: 40. Black to move, mate in 21... ^_^
Jan-30-06  karik: 51. -Rxe6! should win.
Jan-30-06  Djuandemarco: MarvinTsai...40...f3+ 41. Kxf3 Ng5+ 42.Ke3 Nd1+ 43. Kd2 Nf3+ 44. Kc2 Qb8 45 Qb3 Rxb3 and white is completely lost. Notice that all white moves(41 to 44) are forced
Jan-31-06  alefromitaly: 42. ...Qf5 seems good too.
Feb-03-06  Madman99X: Can black win by playing 51 ... Rxe6?
Feb-03-06  Madman99X: Never mind. After further review. 51... Rxe6 is answered 52. Rxe6! Nxe6 53. a4! where the black knight must cover the a-pawn to keep it from promotion, and the black king can hold down the fort on the kingside.
Feb-08-06  LivinFree: A complicated and magnificent game
by both players!
22...e5!! is an extraordinary move,
showing once again Ivanchuk's great
talent. On 23 dxe5, White's Queen is
trapped in 3 moves with 23...Ra8
24 Qb7 Nc5 25 Qxc6 Rc8, which wins.
The position is complicated in that
24 Qxa8 Rxa8 25 exf6 can also be
played, seeming to regain enough
for the queen. But still 25...Bxf6!
will threaten ...b4! so still +.
(26 Rxd3 b4 27 e5 Nxe5 etc.)
Black even has another trap of
the queen after 23 dxe5 with
23...Bc5! in which both of his rooks
are involved (...Re6! - if necessary,
the a-rook goes to a7).
Worse after 22...e5!! is 23 Bxe5?,
since after 23...Ra8! (correct move
order) 24 Qb7 Nxe5 25 dxe5 Ng4,
White's position is a mess, since
both his King and Queen come under
strong attack.
Feb-09-06  LivinFree: I believe it's possible that Black
missed a win on move 43 with
43...Neg5! 44 f3 (44 h4 f3+ 45 Kh2
Nh3! ) 44...Re3 45 Bc4 Nxf3, one
point being 46 d5? Nxe5!
If White's reduced to 46 Bxe6, he's
dropping too many pawns in the piece
down game here.

On move 45 in the game, it looks as
if 45...Nc7! would be a substantial
improvement on 45...Nf8?

Feb-10-06  HardBoys: Continuing your analysis: 46...Nxe5
47 dxe6 Nxc4 48 Rb8+ Kh7 49 exf7!
actually wins for White.
The position is complicated. 44...Re3?! is not best, nor is the accelerating 44...Nxf3: 45 Rb8+ Nf8
46 Kxf3 Re3+ 47 Kxf4 Rxd3 48 Ke4
Rd2 49 a4. Black cannot win here,
and can even lose if he's not careful, since White's a and e pawns create too many threats.
But your line does win if Black finds
the correct key move at 44.
After 43...Neg5! 44 f3 Rd1!
It's this move that wins - after
45 Rb3 g6! And worse is 45 Rb8+ Nf8
46 Rb3 Nge6! wins. If not 45 Rb3,
White simply drops the d-pawn to
...Rxd4, or also loses after 45 Rb8+
Nf8 46 gxf4 Rxd3 47 fxg5 Rxd4.
Feb-10-06  HardBoys: That leaves White with the following
continuation after 43...Neg5!:
44 Rb8+ Nf8 45 gxf4 Ne6 46 Bc4! Nxd4!
(46...Nxf4+ 47 Kf3 g5 48 h4! is not
impressive for Black) 47 Bd3! (White
sets a final cute trap: If now 47...
Ra1 48 f5 Rxa2 49 e6! fxe6 50 dxe6 Nxe6 (Or 50...Ra7 51 Re8 Nxe6 52 Bc4 Kf7 53 Rxf8+! Kxf8 54 Bxe6 which may
draw) 51 Bc4! - which reveals the
power of a bishop, if nothing else.
Black scotches this with the careful
47...g6! 48 a4 Ra1 49 Bb5 Ra3!
Black is in full command here, with
a nice blockade of all of White's pawns. ( +). In summary then, 43...Neg5! does win for Black. So does your later suggestion of 45...Nc7! in the game, since White cannot advance his pawns far enough
before they drop (If Black's rook
were not right behind the e-pawn, there would be a chance of saving the d-pawn by advancing the a-pawn, since
Black would need an additional move
to first get behind the e-pawn, capture it, then get behind the d-pawn, but as it is, he's already ahead of this.) So 45...Nc7! is also
+.
Feb-27-06  LIFE Master AJ: Its a tough game, but relatively well-played.
