  Gypsy: <OJC: < tamar > If 40 ... Rg5 and then 41. Qe4 how does black proceed? > 41...Qg3+ 42.K~1 Re5 looks deadly.

  tamar: <sitzkrieg,OJC> Someone on the main tournament page mentioned this resource this afternoon.

40...Rg5 41 Qe4 Qg3+ 42 Kg1 Re5 so White must pretty much jettison the d pawn with Qf2 or Qd2 to stay afloat.

Sep-28-05  OJC: Oh yeah. I think it's time for a coffee break for me :)
Sep-28-05  Hidden Skillz: after 40.Rg5.. i would have played Qd2 but then after Qxd5 black wins easely.. kasim missed the win for sure
Sep-28-05  DutchDunce: <sitzkrieg> Hmm, never realized Kasim did a thing like that. I applaud him for that.

I'd add Anand and the Polgar sisters to the list of classy players, based on what I've heard. (And certainly it's been a pleasure having Zsuzsa Polgar posting live on!) Actually, I really haven't heard anything bad about most players, just a few extra-notorious ones who will remain unnamed, at least by me.

Sep-29-05  notsodeepthought: Black could have had the edge as posted above, but in any case an easy draw with black is a good start by the least fancied of the WCC contenders.

  Gypsy: < Black could have had the edge as posted above ...> A bit of an understatement.
Sep-29-05  ashalpha: 41.Qf4
Sep-29-05  controlaltdelete: <ashalpha> 41.Qf4? in this game leads to loss of white queen 41. ..Rxf4. 41.Qf4 after 40. ..Rg5 and black is up 2 pawns
Sep-29-05  trevormkidd: <Tamar> I was following this game live, along with all the others, I can't remember exactly how much time Kas had left on the clock but he was under huge time trouble for several moves. Seirawan, who was commenting on the game (and did a great job) missed the error, and it was several minutes later before someone pointed out 40...Rg5! I haven't had a chance to analyse the position but how about 41. Qf2

Regardless, I thought it was a great game and the two of them fought out an even endgame for longer than I expected them too. Kas, as Black, drawing against Moroz is a pretty respectable start.

Sep-29-05  ChessKata: 40...Rg5 seems nice but why not 40....Rxd5?
Premium Chessgames Member
  tamar: <trevormkidd> Thanks for the reply.

after 40...Rg5 41 Qf2 Black has to exercise a little caution (41...Qxa4? 42 Qf8! would be a blunder), but I don't see any real hope for White after 41...Qxd5 Perhaps Moro could find a rook ending that presented technical difficulties.

Must have been hectic time pressure. Nigel Short, in his report on Chessbase, does not even mention 40...Rg5 as a missed win, so it may have eluded notice.

He wrote:

"At this point Morozevich – probably not wishing to waste a white against the lowest rated player in the tournament – opted for a deconstructive plan. This was an unwise choice as Kasim swiftly assumed the initiative to enter a rook and pawn endgame a doubled pawn to the good."

Sep-29-05  TIMER: Yes, it could have been a third win for black. Why did Kasimdzhanov rush in with Qd5? It was his 40th move he could have taken the remaining time before the time control.

  tamar: <ChessKata: 40...Rg5 seems nice but why not 40....Rxd5?>

That also appears to work. 40...Rxd5 41 Qe4 Re5 42 Qa8 was probably what Kasim feared with very little time to analyse, but 42...g5 looks safe enough, and Black has some tricks like 43 Qc6 Qf7 that can win back the initiative.

Premium Chessgames Member
  Mateo: Moro's sac (36. Bd3?) was a really bad move. He should have lost the game after that. I think <tamar> is right.

40... Rg5 with the threat Qg3+ should win for black. 41. Qe4? Qg3+ 42. Kh1 Re5 .

41. Qd2 Qg3+ 42. Kg1 (42. Kh1 Re5 ) Re5 43. Rf8 Re4 (44. Qxa5? Re2 ; 44. Qc2 Re1+ 45. Rf1 Qe3+ 46. Qf2 Rxf1 47. Kxf1 Qc1+ wins a pawn) 44. Rf3 Qe5 and black should win.

Sep-30-05  arifattar: Ok, now we know why he wins.
Sep-30-05  rexeterna: I doubt that's exactly the picture that Kasim wanted up...
Sep-30-05  Resignation Trap: Thanks to for that great photo! Kasim is an inspiration to us all by showing us how to maintain two difficult positions at the same time.

Perhaps someone can come up with a really snappy caption!

Sep-30-05  Phoenix: The picture above was taken just seconds before Morozevich yelled out, "PEEK-A-BOO!"

  Gypsy: Kasimjanov's error <40...Qxd5?> is a bit hard to comprehend. -- That is, discarding a severe time pinch. -- One can easily understand Kasim overlooking the smooth win after the <40...Rg5!!>, because his attention had to be drawn to the debate about how to capture on d5. But, and this is the puzzle, why did he chose the drawing <40...Qxd5?> instead of the more natural <40...Rxd5>? The latter would have won. Kasim clearly had to make an evaluation error, as both d5 captures obviously are candidate moves.

I think <tamar> is right about Kasim underestimating his own chances after the <40...Rxd5 41.Qe4 Re5 42.Qa8 g5 ...> -- at least, that is the only realy plausible explanation we all came up with. An alternative explanation I can come up with is that Kasim overlooked <40...Qxd5? 41.Rxd6!>. And only a realy realy severe time pressure could explain that.

<Resignation Trap: Thanks to for that great photo! Kasim is an inspiration to us all by showing us how to maintain two difficult positions at the same time.> I love your sense of humor!

Oct-03-05  John Abraham: <Phoenix> That's classic.

  WannaBe: <Caption> Oh my God, what did I just move?!? I didn't do that, did I?!?!?!? I can't believe I made that move!!! What was I thinking!!!!!!!
Jul-18-08  The Ninth Pawn: From Game Collection: The Ninth Pawn's Chess Course :

In Morozevich vs Kasimdzhanov, 2005 , White can play 41. ♖d8x♙d6 because it is defending the White d4-queen THROUGH the Black d5-queen, which is the only attacker. Also notice that the d6-rook is ALSO defended through the d5-queen by the d4-queen.

Mar-05-09  shahjinan: seems like in photo, Kasimdzhanov is copying Fischer..:P
