Would you mind if I incorporated your explanation (credited of course)? Thanks. It'll take me a while to work through that. After today's game. I am so glad today is not a 'sinecure' after all.

Mar-10-05  Marco65: <cheski> No problem, but don't give me any credit! I would never think of Bxe6 myself if I hadn't found it's a thematic sacrifice on some books about the Sozin.
Mar-10-05  worktobedestroyed: I thought 24. f6+ not sure what I've missed
24. f6+ Kh8 25. Qh6 Qc5+ 26. Rf2

  YouRang: Woo hoo! I finally got one right!
(I admit I didn't see the entire line that the game followed, but I picked the following 2 moves.)
Mar-10-05  Robert P: what about 27.Rf7, bringing the bishop in the killing zone, it seems more powerfull than gxh7
Premium Chessgames Member
  benveniste: I think Black has drawing chances if he tries the following line: 25 fxg6
26 fxg6 Rf7!
27 gxf7 Rf8
Mar-10-05  aw1988: After fxg5 wouldn't something like (not precise move order, just ideas) h4, and Ng5 then be winning?
Mar-10-05  dac1990: Notable here is the fact that Bobby was 13 when he played this game.

If only the puzzle had been "White to play and lose" :)

  benveniste: <aw1988>, I think white's short a tempo to get the knight to g5. Here's how it played out when I tried it:

26 fxg6 Rf7!
27 gxf7 Rf8
28 Qe6 Qc5+
29 Re3 Bg5
30 Nd1 Qd4
31 c4 bxc3
32 bxc3 Bxe3+

I evaluate this as drawn.

I think White improves with
26 fxg6 Rf7!
27 gxf7 Rf8
28 Qe6 Qc5+
29 Re3 Bg5
30 Nd1 Qd4
<31. Qe8>

What do you find for Black in this case?

Premium Chessgames Member
  benveniste: <beatgiant> I believe it's a different flavor of the same draw: 31 Qe8 Bxe3+
32 Nxe3 Qg7+
33 Kf2 Qxf7+
Premium Chessgames Member
  beatgiant: <benveniste>
That is pretty convincing. Have you looked at earlier possible improvements, for example

25 ...fxg6
26 fxg6 Rf7!
27 gxf7 Rf8
<28 Ne2>

In this very tricky position, I see possibilities like

28... Rxf7
29 Nd4 Qc5
30 Re3 Qd5
31 Nf3

Premium Chessgames Member
  benveniste: <beatgiant>I hadn't tried Ne2 until you mentioned it, but it looks worse for White. Here's the continuation I see:

31. Nf3 Rf6
32. Qg5 Qxg5+
33. Nxg5 Rxf1+
34. Kxf1 Bxg5 (2 bishops v. rook)

Good lines. You've got me convinced that 25 ...fxg6
26 fxg6 Rf7! is a big improvement, and I don't see how White can win against it.
Aug-09-06  Chicago Chess Man: The best move for white was 23. Qh5! Then if PxN, 24. g6 should win. Fischer's 23rd move was enough to win, but 23. Qh5 wins on the spot, I think.

  plang: An early example of Fischer using the Sozin attack. He had not worked out all the refinements yet but it was still a lethal weapon in his hands. 10..Na5 is not played much anymore as the loss of time fuels whites initiative. Through move 14 the game follows Sozin - Ilyin-Znenevsky 1931. Fischer plays 15 f5 instead of Sozins 15 Qh5. It is not clear that this is an improvement. 16..Kh8 does not work out very well; Kasparov suggests 16..Re8 with the idea of ..Bf8. 17..Nf3+ seems to speed up whites attack; 17..Nc6 is an alternative. 20 ef allows black counterplay on the long diagonal; 20 Bd4 would have been a quicker win. Both players missed the miraculous defense 25..f6 26 fg..Rf7 which probably would have led to a draw.

<Chicago Chess Man: The best move for white was 23. Qh5! Then if PxN, 24. g6 should win.>

Yes - as was already mentioned in previous kibitzing, Fischer's 23.Bxg7+ should have led only to a draw, had Cardoso found the miracle defence 25...fxg6 26.fxg6 Rf7!! 27.gxf7 Rf8 (threatening Rxf7) 28.Qe6 Qc5+ (that's the right timing for this move) 29.R1f2 (29.Re3 Bg5; 29.Kh1 Qe5) 29...Bxf3 (29...Qe5 30.Re3) 30.Ne4! (30.Qxe7? Rxf7! 31.Qxf7 Qg5+ and mate) 30...Qe3 31.Qxe7 Qe1+ 32.Rf1 Qe3+ 33.Rf2 and draw by perpetual.

Instead, 23.Qh5!! combines pressure on the h-file and the long diagonal, creating the lethal threat of 24.g6 h6 25.Qxh6+:

23...Kg8 24.f6! Rfe8 25.fxg7 Qxf3 26.Rxf3 Bxf3 27.Qxf3 bxc3 28.h4 cxb2 29.Bxb2.

23...Qxf3 24.Rxf3 Bxf3 25.Bxg7+! Kxg7 26.Qh6+ Kh8 27.g6 fxg6 28.fxg6 Rf7 29.gxf7 bxc3 30.Qe3 threatening mate on the long diagonal as well as the two bishops.

23...f6 24.g6 h6 25.Be3! and the threat of saccing the bishop on h6 is decisive, e.g. 25...Qxf3 26.Rxf3 Bxf3 27.Qxf3 bxc3 28.Bxh6 gxh6 (28...Kg8 29.Qd5+ Kh8 30.Qe4) 29.Qe3.

Nov-09-11  qqdos: <Plang> in addition to the Sozin game you quote, cf. Boleslavsky vs Aronin, 1949, which follows this game upto 12.g4 when Aronin diverged with 12...b5 13.g5 Nd7? 14.Nxe6! Boleslavsky comments that Black did not notice this sacrifice on e6, effectively deciding the game. Fischer was a fan of Boleslavsky's deep analytical writings on Chess and may have been inspired by this sacrificial and thematic victory by White in the 6.Bc4! Sicilian. See the Jimmy Adams 1988 book of Boleslavsky's Selected Games, p.113.
