Oct-17-09  DarthStapler: I got the first move and considered the second move
Oct-17-09  WhiteRook48: I tried Qxf7???
Oct-17-09  BOSTER: No doubt that move 24...Qb7 <patzer2> is the good defensive move and black can play much longer then in the real game.But, is this enough to equalize the game?
Oct-18-09  patzer2: <Boster> Probably against best play 24...Qb7 is not enough to equalize, but it may be enough to draw. Certainly against less than strong play, it's enough for a higher rated player with the Black pieces to equalize and even win.

Apr-06-16  SimplicityRichard: A brilliant game! Nevertheless, the ECO for this game is not A07 but B23; this is not a King's Indian Attack but a Closed Sicilian Fianchetto variation.#
Apr-06-16  SimplicityRichard: Or more precisely B24 as indirectly pointed out by <LIFE Master AJ> game illustration.#
Jul-17-21  Brenin: 24 Qxf7 is tempting, but apparently insufficient, while 24 Be6 looks good enough, e.g. 24 ... fxe6 25 Qf8+ Kd7 26 Qg8 Rh5 27 Qxe6+ Kf8 28 Qxg6+.
Jul-17-21  mel gibson: I didn't see that.

Jul-17-21  Cheapo by the Dozen: I went with 24 Qxf7, correctly judging that the result would be material near-parity plus a dangerous attack.

Unfortunately, as the engine points out, the dangerous attack is by BLACK, and while loses emphatically.

Jul-17-21  stacase: 24.Be6 doesn't leave Black any good moves. White's Queen finally cleans up like you would clean a fish. I was happy to get the first two moves on a Saturday.

  perfidious: <jls....The sound you hear from my post is the crisp crack of self-flagellation.>

Never had the impression you ran that way. (laughs)

Jul-17-21  agb2002: Black threatens Bxh3.

The white queen x-rays the rook on a8 and the square f8. These details suggest 24.Be6:

A) 24... fxe6 25.Qf8+ (25.dxe5, with the double threat Qxa8 and Qf8#, is met with 25... Qb7) 25... Kd7 26.Qg8

A.1) 26... Rh5 27.Qxe6+ Ke8 (27... Kd8 28.Rf8#) 28.Qxg6+ Kd7 (28... Kd8 29.Rf8+ Ke7 30.Qe8#) 29.Qxh5 wins decisive material.

A.2) 26... Rh4 27.Qxe6+ Ke8 28.Qxg6+ Kd7 29.Qe6+ Ke8 30.Qg8+ Kd7 31.Bf2

A.2.a) 31... Rg4+ 32.Bg3 looks winning. For example, 32... Bxd4+ 33.cxd4 Qb6 34.Rxe7+ Kxe7 35.Rf7#.

A.2.b) 31... Rh3 32.Bg3 as above.

B) 24... Bxe6 25.dxe6 Ra7(b8) 26.exf7 Bg7 27.f8=Q+ Bxf8 28.Qxf8+ wins a piece.

C) 24... f5(6) 25.gxf6

C.1) 25... exf6 26.Bg5 wins a pawn at least (26... fxg5 27.Qf8#).

C.2) 25... Bxf6 26.Bg5 as above.

Jul-17-21  alshatranji: It looks rather complicated, but White doesn't really have a lot of options to advance his position. Still, 29. Bf4 seems more effective, unless I missed something.
Jul-17-21  alshatranji: Is this really chrisoewn in the first post? He is almost fully coherent. It's kind of eerie. "the revelation of Be6 dawned once I couldn't get Bxc8 to work"--that's very good.

  Jimfromprovidence: Ok I found 24 Be6 but was not sure how to proceed after 24...Qb7 (providing an escape square for the king) 25 Bxf7 Bf5.

26 Bg8 attacking the rook looks interesting but how to follow up?

Jul-17-21  johnlspouge: @<perf>: Self-flagellation is still a constant friend 12 years later (rueful laugh).
Jul-17-21  saturn2: <Jimfromprovidence: 24 Be6 Qb7 25 Bxf7 Bf5> White can play 26.Be6 and after an exchange of bishops and queens doubling rooks on the f file white seems good for a win with the plus pawn.
Jul-17-21  devere: 24. Be6 is much too obvious for a Saturday. And it seems that Black should try 24...f6, although White still has a winning attack.
