Aug-19-11  qqdos: <correction> in the above post, the John Nunn line should begin 22.Qxh5 Bxg5 23.Bxg5 f6 then 24.Be4! Rh8 etc. as demonstrated by Nunn. Yusupov had indicated that he feared this possibility (22...Bxg5 in preference to 22...Nf6? chosen by Ivanchuk) and (during the game) he had not been able to see how he could develop his attack. Hope this now makes sense. Sorry for the confusion.
Aug-01-16  posoo: now look at DIS kabitzer "BONJAMIN LAU,"

wat on EARTH cod his problem have BEEN?

He has "LEFT" chusgums dot com? WHY?

Becos people are yelling at him!?

Yelling at peple is da ESSENCE of chesse? WHO DOSUNT enjoy shouting at each other?

CRAZY CRAZY

i wonder if da man is living in da woods now. peaceful like THORROW.

Nov-26-16  Saniyat24: Can White play Bh6 as his 33rd move?
Mar-04-17  The Kings Domain: At first I thought the attack was going nowhere only to have the whole plan slowly reveal impressively. Memorable win by Yusupov. Those were the last great days of the game.

  ChessHigherCat: This wins the queen and white has a lot of pawns, but there's probably better:

23. Nxe6+ Qxe6 24. Qh6+ Kh8 25. Bf5+ Kg8 26. Bxe6 fxe6 27. Qg6+ Kh8 28. Bh6 Rg8 29. Qf7 Bd8

  ChessHigherCat: I didn't even look at the 23...fxe6 variant because I figured the black queen would want to get into the defensive act. When I checked out the game line it looked like a blitz game with so much dithering, hithering and thithering (whence the name ping-pong I suppose)

  al wazir: I got the first move, but I had no follow-up plan.

There must have been a better continuation for black. After 35. Qxe6 he was still about even in material. Maybe 35...Rf7 instead of ...Bd8 ?

Feb-09-19  Walter Glattke: There is no mate chance, but the pawn storm 39.h4 etc. will win for white.
Feb-09-19  stacase: <al wazir: I got the first move, but I had no follow-up plan.>

Same here, I didn't see the mating pattern formed by White's Bishop occupying e6 covering f7 & g8 while Queenie threatens mate h3=>h6 supported by the d2 Bishop. (Wins the Black Queen)

But then after playing it out I didn't exactly see why Black tips his King on 38.g5 ... It's White's Queen & 4 Pawns against Black's Rook, Bishop & Knight. I guess that's a won game for White, but as one of those little hints we get on posting says, "The hardest game to win is the won game" (-:

Feb-09-19  stacase: stacase: Ha! <What Walter G> just posted
Feb-09-19  rossvassilev: very difficult??? are you serious?
Feb-09-19  SpamIAm: <stacase>, methinks that black threw in the towel after 38.g5 because after the knight moves 39.Qd7+ really ties black up hopelessly.
Feb-09-19  stacase: 39.Qd7 <SpamIAm> That's the move I would have made providing Black didn't throw his Knight under the bus.

Feb-09-19  RandomVisitor: It seems that the odd queen shuffle to h3 is required in order to win.
Feb-09-19  The Kings Domain: Good and funny game from the good old days, Yusupov unleashed his inner Anderssen with this one. Good game selections by the site in the past few days.

  patzer2: For today's Saturday puzzle (23. ?), I calculated as far as 23. Nxf6! fxe6 24. Qh6+ Kh8 in the game continuation.

However, I did not consider 25. Bf5+! +- (+5.32 @ 44 ply, Stockfish 10). Instead, I went for 25. Bb1+ Kg8 26. Qg6+ Kh8 27. Qh6+ Kg8 = with a draw by perpetual check.

P.S.: As <DrMAL>'s Aug 17, 2011 post states, Black's decisive mistake was 22...Nf6? allowing 23. Nxf6! +- (+5.06 @ 38 ply, Stockfish 10).

Instead, as <Random Visitor>'s deep 75 ply Stockfish analysis indicates, Black can hold it level with 22...Bb4! =.

Feb-09-19  devere: 23.Nxe6+ is the only move, otherwise White loses. Whether Black replies 23...fxe6, Qxe6, or Kh8 the win for White isn't easy. One possible line is 23.Nxe6+ Qxe6 24.Qh6+ Kh8 25.Bf5+ Kg8 26.Bxe6 fxe6 27.Qg6+ Kh8 28.d5 exd5 29.Bc3 Be2 30.h3 Bf3 31.g4

and the pawn advance wins the game for White.

  agb2002: White has two pawns for a rook.

Black threatens Nxh5.

The first idea that comes to mind is 23.Nxe6+:

A) 23... fxe6 24.Qh6+ Kh8 (24... Kf7 25.Qg6#) 25.Bf5+ Kg8 26.Qg5+ Kh8 27.Qh4+ Kg7(8) (27... Nh5 28.Qxh5+ and mate in two) 28.Qg3+

A.1) 28... Kh8 29.Qh3+ Kg7 (29... Kg8 30.Bxe6+ + - [Q+4P vs r+b+n]) 30.Bxe6 (with the double threat Qh6# and Bxc8)

A.1.a) 30... Rh8 31.Qg3+ and 32.Bxc8 + - [Q+4P vs r+b+n].

A.1.b) 29... Qxe6 30.Qxe6 as above.

A.2) 28... Ng4 29.Qxg4+ Bg5 (29... Kf6(7) 30.Qg6#; 29... Kh8 30.Qh5+ Kg7 31.Qg6+ Kh8 32.Qh7#) 30.Qxg5+ Kf7 31.Bg6+ Kg7(8) 32.Bh5+ Kh7(8) 33.Qh6+ Kg8 34.Qg6+ Kh8 35.Bg5 and White seems to end up three pawns ahead.

B) 23... Qxe6 24.Qh6+ Kh8 25.Bf5+ followed by the zigzag maneuver looks similar to A.

C) 23... Kh8 24.Qh6 seems to transpose to the previous lines.

Feb-09-19  RandomVisitor: After 18.Qg4 white is projecting force on the kingside but has no breakthrough. Amazingly the machine thinks that black has a strong advantage:

Feb-09-19  drollere: Nxe6+ was not difficult to find, as were the following two moves; but i found it hard to see the continuation from move 26, which is where the repetitions necessary to align Q+B occur.

  saffuna: The players said playing these Quarterfinal candidates games were the only relief, the only chance to get away from the uncertainty from theAugust Coup and the collapse of the Soviet Union.

According to Inside Chess the players spent most of the time away from the games trying to learn what was going on in Moscow. No Internet back then, but there was CNN and I assume other TV and radio news stations.

  patzer2: Correction: I meant of course 23. Nxe6! +-, not 23. <Nxf6> which isn't a legal move.
