Sep-24-07  Landman: 44.♖a5?! allows an easy draw. Maybe Svidler is counting on Moro not going for it?
Sep-24-07  Marmot PFL: Queens off and pawns traded, looks like Svidler giving up trying to win.
Sep-24-07  Bob726: Draw!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Sep-24-07  Bob726: according to official website
Sep-24-07  Landman: <Billosky> It's bizarre after the Black ♗ had already come to d5 - long diagonal weakness. To be fair, Rybka dropped this as the main line after a while.

Sep-24-07  YouRang: Svidler (white) appeared to be better most of the time, although perhaps his best chance occurred after 32 moves (diagram):

Here, white played 33. Bxc5, missing a winning deflection:

33. Bxe6+! Qxe6 <not much choice: 33...Rxe6? 34. Qxg7#; 33...Kh8? 34. Qxh6#, but this leaves the bishop unguarded>

34. Bxc5! <and the pins the 2 black rooks, going up the exchange on top of an aggressive position.>

  al wazir: There was a lot of scope for tactics in this game. I liked 31. Bxg7 Rxg7 32. Qxe6+ Kh1 33. Rxd6 axb5 34. Ne5, but I'm not sure whether it wins.

Too bad Svidler didn't try it. It might have been a brilliancy.

After 33. Rxd6, doesn't black have 3...Nxd6?

Awesome. I bet he's kicking himself now for missing that combo.

  al wazir: <YouRang: After 31. Bxg7 Rxg7 32. Qxe6+ Kh1 33. Rxd6, doesn't black have 33...Nxd6?> Well, yes. I had been looking at lines that began with 31. Rxe4, and I forgot that the ♘ was there. But I still think white had some kind of combination in this position.
Sep-24-07  you vs yourself: Svidler telling Garcia to shut the duck up: http://www.chessmexico.com/images/r...
Sep-25-07  Sularus: <YouRang> and how will white win if black replies 33. ... Kh8 ?

thanks.

Sep-25-07  percyblakeney: <Sularus> Qxh6 is quite strong in that line :-)
Sep-25-07  percyblakeney: At the press conference Svidler talked about missing 33. Bxe6, Morozevich said that he had seen the move but had planned Rxe6 against it :-)

Svidler also talked about looking at a double exchange sacrifice, maybe somewhere between move 20 and 23, including Bc3 followed by a black Ne4 and then Rxe4 and Rxd6.

Sep-25-07  sanyas: <you vs yourself> Funny picture, but isn't that Paul German?

<percy blakeney> we are all Kramniks at heart :P

Sep-25-07  Microdot: <YouRang>Svidler (white) appeared to be better most of the time, although perhaps his best chance occurred after 32 moves

No, first of all Morozevich was 100%winnig after Svidler's blundered badly at move 29?? 29.Be3??,Rf8! 30.Bd4,
after this, Moro was 100% winnig
instead of 30...a6, 30...Bc5 was an
easy win for Morozevich, pity he was in time truble, Shredder 10 gives black 3 pawns advantage after 30...Bc5! Anyway, Moro is a better player than Svidler so far and there for 1.5/0.5 is good for Morozevich.

Sep-25-07  Microdot: All I can say about this beautiful caro-kann is
Morozevich outplayed Svidler with the black pieces first, then blundered with 30...a6?! instead of 30...Bc5! leads to a beautiful win for black. Even after 30...a6?! 31.c5,axb5! 32.cxd6,Qxd6 was winning a pawn for black, but again Moro blundered with 30...Bxc5?! because he was in time truble, what a pity.
Sep-25-07  Microdot: <percyblakeney:> At the press conference Svidler talked about missing 33. Bxe6, Morozevich said that he had seen the move but had planned Rxe6 against it :-)

No, Morozevich said that he had planned 33...Qxe6 34.Bxc5,Nxc5 35.Rxe6,Nxe6 with very high draw chances(Because of unbalance material Q VS R+B

Sep-25-07  YouRang: <Microdot> I agree that 30...Bc5 would have been a great move for Moro, but it's also fairly deep and not so obvious.

One can always compare each move with computer analysis, and one will often see players miss the move heavily favored by the computer. But most of the time, it is unreasonable to expect that a player should see the computer move, particularly in time trouble.

But 33. Bxe6+! followed by Bxc5 was a fairly basic 2-move tactic that a GM should see. He played 33. Bxc5 instead, knowing that c5 was guarded by the queen. IMO it's not too much to think that a GM would consider removing the guard, especially with a pawn-capturing check.

Basic rule: "look at all forcing moves, checks and captures".

Sep-25-07  percyblakeney: Morozevich's games often get into positions where it's easy to go wrong also for players on this level. Kramnik played an excellent game with white but still made a mistake that allowed Morozevich good saving chances, Anand was winning but somehow didn't win, Aronian should have won that endgame but couldn't, and here both players missed better moves in time trouble.

If he had been "unlucky" in all his games Morozevich could have had a worse result in Mexico, but this far he seems to have been the most talented of the participants when it comes to defending bad positions.

Sep-28-07  notyetagm: GM Ian Rogers:

<However Morozevich then returned the favour with 30...a6 (instead of 30...Bc5!) allowing Svidler to fight back with 31.c5!. This induced another mistake from Morozevich (32...Qb6) but despite two minutes thinking Svidler did not see the simple winning combination 33.Bxe6+!! Qxe6 (if 33...Kh8 34.Qxh6 checkmate!) 34.Bxc5! and Black must give up material. "I think we both missed that g7 was hanging [with mate after ...Rxe6]," said Svidler. "Yes, I was planning to take with my rook on e6!" admitted Morozevich. >

Yes, this lovely combination would have given Svidler his first win.

Sep-28-07  Microdot: <notyetagm>Yes, this lovely combination would have given Svidler his first win.

No, this is because after 33.Bxe6+, black can reply 33...Qxe6 34.Bxc5,Nxc5 35.Rxe6,Nxe6 Q vs R+B
I analysed this variation so deep
and draw chances for black is very high,
Svidler can not win this Q versus R+B from big morozevich.

Sep-28-09  YouRang: <Svidler can not win this Q versus R+B from big morozevich.> lol - nope, no bias there. ;-)

I have little doubt Svidler could have won it handily. He's beaten Moro before with less material advantage that this. But, of course, we'll never know for sure.
