Kibitzer's Corner
< Earlier Kibitzing  · PAGE 1 OF 2 ·  Later Kibitzing>
Oct-08-05  NakoSonorense: With this win, Moro ties Anand for third place with only 5 games to play.
Oct-08-05  John Abraham: A great and important win for Morozevich!
Oct-08-05  rifraf: Can anyone tell me why not 34. ...Qxg4? Seems like a good endgame for black.
Oct-08-05  csmath: Interesting that Moro plays a regular opening. Then he plays weird fianchetto.

Leko reacted properly on Moro's attack with

24. h5?! ... fxe4!

25. Qxe4 ... Nc5

missing 25. ... Rbf7! 26. Rdf1 ... Nc5 27. Qe2 ... Bxd5! with a serious advantage.

26. Qe2 ... Bxd5!

27. Rxd5 ... Rbf7

28. Rf1 ... gxh5!

29. Qxh5 ... Qf6

30. Bg4 ... Ne4!

31. f3 ... Qg7

32. Rdd1 ... Nf6?

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.

33. Qh3 ... Nxg4

34. Qxg4

Now Leko was short on time and could have forced ending with general exchange starting with queen exchange but he makes a piece sacrifice here:

34. ... Qf6!?

35. Qe4 ... Bf4!?

36. Kf2 ...Qh6!?

very speculative play by the guy who doesn't play this way. Apparently he wants to win this game badly!

37. gxf4! ... Rxf4

38. Rh1! (cool and collected) ... Qg7

39. Qd5 ... e4?

Blunder that decides the game

40. Rdf1!

Moro brings in all his pieces in the defence and white cannot penetrate. A piece down he is now doomed.

Leko played courageous but in the time trouble he made a decisive error. From almost a won game to completely lost game. It happens.

Oct-08-05  Assassinater: <Can anyone tell me why not 34. ...Qxg4? Seems like a good endgame for black.>

Yasser commented on this on playchess (on the queens and rooks being trade off). It seems that the knight in that endgame is superior to the bishop, as the black a, b, d and e pawns are all fixed on black squares. The king will march up on the light squares and penetrate black's camp. Mind you, this is all very general, but that's the gist of what Yasser said.

<Leko played courageous but in the time trouble he made a decisive error. From almost a won game to completely lost game. It happens.>

How was the game won for Leko? It seemed like he had some positional pressure on Moro, but nothing major...

Oct-08-05  csmath: Read my analysis above. In two critical places Leko played inferior moves.
Oct-08-05  Assassinater: <missing 25. ... Rbf7! 26. Rdf1 ... Nc5 27. Qe2 ... Bxd5! with a serious advantage.>

In that line, white looks like he can grab the bishop with 26. Bxe6. The two Rooks aren't really able to corner the king, while the centralized knight is able to deter most threats.

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.
