Oct-08-05  Assassinater: <This was a critical moment, here Leko missed 32. ... Nd2 a killer move that could have won the game 33. Rf2 ... Rf6 34. Qh3 ... Bg5 and white is in serious trouble.> 32... Nd2 33. Rf2 Rf6 34. Rxd2 Bxd2 35. Rxd2 looks fine for white. He's won two minors for a Rook and the bishop and pawn should be able, after a few defensive moves, be able to hold the fort. Note that the Rook on d2 covers checks on the f-file.
Oct-08-05  csmath: <<32... Nd2 33. Rf2 Rf6 34. Rxd2 Bxd2 35. Rxd2 looks fine for white.>>

BS my friend. This is where you need to analyse a bit further.

35. ... Rh6 and white is completely lost.

Oct-08-05  csmath: In this game, as my analysis shows, Leko missed superior moves twice. This one in 32nd move was a killer move that might have decided a game in his favor. I am not certain of that but I am certain that Morozevich would have a serious, serious trouble.

Leko blew it though of course he can be excuse with a lack of time.

Oct-08-05  Assassinater: <BS my friend. This is where you need to analyse a bit further.

35. ... Rh6 and white is completely lost.>

Alright. I goofed. But it wouldn't be the first time I trapped my queen. :P

Oct-08-05  csmath: It is not forced win but it is a serious pressure. The problem with Leko is that he was in a serious time trouble and could not find the proper moves.

Moro was like a fish, it seems unbalanced positions are his domain.

  Gypsy: The end of this game is sad: I splendid strategic effort vasted.

I think the endgame after 34...Qxg4 35.fxg5 Rxf1 36.Rxf1 Rxf1 37.Kxf1 Kg7 ... is a win for Black, ... or awfully close to it.

  tpstar: <csmath> I don't mean to harp on syntax, but here your word choice cancels your idea. I believe you meant "Moro was in his element" because he is at home in such unbalanced positions, not that he played "like a fish" which is bad of course. =)
Oct-08-05  csmath: I tend to agree to some degree with Seirawan as noted above. The ending is extremely tricky, perhaps that is what ticked off Leko from trying. Not so sure black has the meaningful advantage. Because of the command of the white fields white king will be able to assume his royal ending role and black has to be extraordinary careful if playing for a win else he could lose as well. A draw would be more likely outcome.
Oct-08-05  csmath: <<I believe you meant "Moro was in his element">>

Yes. That is exactly what I meant, you got it. This is what he plays the best.

Oct-08-05  Akavall: <csmath> You say that 34. ... e4 was the blunder that decided that game, what should've Leko played? To me it seemed that the game was lost after 36. ...Qh6?, the sacrifice is not sound.
Oct-08-05  csmath: 39. ... e4?

was a blunder.

39. ... Rxf3

40. Qxf3 ... e4 now

41. Qxf8 ... Qxf8

and it seems that black has plenty of checks for a draw.

Oct-08-05  Akavall: Yes, I see it now, Thanks. Inbetween 40...e4 is the key, maybe Leko missed it? After 40...Rf3+ I am not sure if black has enough checks.
Oct-08-05  Hesam7: <csmath: Leko blew it though of course he can be excuse with a lack of time.>

No he can not be excused! San Luis has been a disaster for him and it is so because he gets into time trouble and blunders in very promising (if not winning) positions and then loses. This game and the game with Topalov in round 1 are the best examples. He should learn to manage his time properly, as we all know time management is part of the game.

Oct-08-05  Hesam7: <Gypsy: I think the endgame after 34...Qxg4 35.fxg5 Rxf1 36.Rxf1 Rxf1 37.Kxf1 Kg7 ... is a win for Black, ... or awfully close to it.>

I do not think so. After 34... Qxg4 35.fxg5 Rxf1 36.Rxf1 Rxf1 37.Kxf1 Kg7, White can play 38. a3! making b4 a target. After that White can hold the game easily.

Oct-08-05  Dionyseus: <I think the endgame after 34...Qxg4 35.fxg5 Rxf1 36.Rxf1 Rxf1 37.Kxf1 Kg7 ... is a win for Black, ... or awfully close to it.>

I don't see the win, and neither does Shredder 9.
34... Qxg4 35. fxg4 Rxf1 36. Rxf1 Rxf1 37. Kxf1 Kg7 38. Ke2 Kf6 39. Kd3 Ke6 40. a3 bxa3 41. Nxa3 =

Oct-08-05  csmath: <<He should learn to manage his time properly, as we all know time management is part of the game.>>

Well, you got the point. It is easy to get into a time trouble with Moro though (Kasim did the same) since the guy is playing unbalanced positions all the time. If allowed.

  Gypsy: Well, it is hard to argue with Schreder and Co. And I honestly did not even consider a2-a3 as a White resource; I would be more worrying about various forks and/or blocades. In a practical game, I would have merrily play this endgame on, hoping for a favorable result, and understand that it may come....
Oct-09-05  Boomie: The win after <csmath's> 32...♘d2 may go something like:

32... ♘d2 33. ♖f2 ♖f6 34. ♕h3 ♘e4 35. ♖ff1 ♘c3 36. ♖a1 ♗f4 37. gxf4 ♖h6 38. ♕g3 ♘e2 39. ♕e1 ♘xf4+

Certainly a knight to remember.

Oct-09-05  percyblakeney: White's knight never looks too active on c2 as it stands there for almost 40 moves, but with 47. Qe3 he might have won without having to move it again at all... Good to see Moro doing better than expected, and 1.5-0.5 against Leko ensures that he will finish ahead of him if they share final result.
Oct-09-05  FHBradley: <csmath:> (or anyone else, for that matter). I may be missing something obvious, but what happens if white plays 32 ... ♘d2 33 ♖h1?
Oct-09-05  Boomie: <FHBradley> 32...♘d2 33. ♖h1 ♖f6 with the threat of "mating" the white queen after moving the bishop from a6. Here are a couple of attempts to get as much as possible for the queen. Both lines look hopeless for white.

33. ♖h1 ♖f6 34. ♘e1

(34. ♖h2 ♘xf3 35. ♗xf3 ♖xf3 36. ♕xf3 ♖xf3 37. ♔xf3 e4+ 38. ♔g2 ♗f4 39. ♔g1 ♗xg3 40. ♖e2 ♕g4 41. ♖dd2)

34...♗g5 35. f4 exf4 36. ♖xd2 ♖h6 37. ♖f2 ♖xh5 38. ♖xh5 h6

Oct-10-05  FHBradley: <Boomie> Thanks, I can see it now.
Oct-20-05  Hesam7: Leko loses out of a winning position. After 26. Qe2, Fruit gives:

26... Rbf7 27. Rhf1 Bxh3 28. Kxh3 gxh5 29. Qxh5 Ne4 30. f4 Qd7 31. Kh2 exf4 32. Qxh6 Nf2 33. Kg1 Nxd1 34. Rxd1 fxg3 35. Nde3 Rf6 36. Qh5 Qc6 37. Qxa5 (eval: -1.39)

Oct-20-05  Hesam7: Also after 32. Rdd1, Fruit gives:

32... Nd2 33. Rf2 Rf6 34. Nd4 exd4 35. Rdxd2 Bxd2 36. Rxd2 Rh6 37. Qxa5 Rh2 38. Kxh2 Qh6 39. Bh3 Qxd2 40. Bg2 Qh6 41. Kg1 Rg8 42. g4 Qe3 43. Kh2 Qf4 44. Kg1 Qd2 (eval: -0.99)

Depth: 17
277M nodes
694K nodes/sec

At this point it seems that even 32... Nxg3 is also possible, after 33. Kxg3 Bf4+ 34. Kf2 (I think other moves lose due to the bad position of white Queen) Fruit gives:

34... Rf6 35. Qh4 Rh6 36. Bh5 e4 37. Nd4 exf3 38. Qg4 Qe5 39. Rfe1 Qxh5 40. Qxh5 Rxh5 41. Nxf3 Be5 42. Rh1 Rg5 43. Rhg1 Rg7 44. Rg2 (eval: -0.41)

Sep-06-13  isemeria: It seems this is the last game Leko played Sveshnikov sicilian as black. I couldn't find any games after San Luis 2005.

I wonder why he abandoned Sveshnikov because his results were quite good with it?
