Kibitzer's Corner
Sep-21-09  Trader19: White missed a win. 24.Qg3!...instead of 24.Qh3?
Aug-10-16  DrGridlock: Timman gives this as an attacking "fragment" in "On The Attack."

Timman draws attention to White's blunder on move 24, mentioned above, which throws away the win for a draw.

White's error, as Timman notes, is that after 25 ... c3 x b2 the pawn cannot be stopped.

Recognizing this, it should be noted that at move 24 White can also play bxc3 (stopping the pawn), with another path to a won game.

24 bxc3 Qxd5
25 Rxb7 Qxf3
26 Rxf3

and White has a knight for a pawn

Nov-09-17  Retireborn: In NiC 2005/6, De Firmian gives 22...Qxd5 23.Rxg7+ Kh8 24.Nf6, but Houdini points out that 24...Qd3! wins for Black then.

Houdini suggests 22...Qxd5 23.Rxg7+ Kh8 24.Qg3 Qd3 25.bxc3 Bh4 26.Qxh4 Qxe3+ 27.Kh1 Qh3 28.h3 Rg8 29.Rfxf7 Rxg7 30.Rxg7 Bc6 31.c4 keeps White's advantage to a minimum.

22...f5 is a losing move and it's a pity White missed 24.Qg3 Bf6 25.Rxf5 cxb2 26.Rxh7+ Kxh7 27.Nxf6+ Rxf6 28.Rh5+ as given by De Firmian.

Apr-14-19  clement41: <Retireborn> : in DeFirmian’s line one should see that after 24 ...Bf6 25 Qf6 Qe6 26 Bg5!? (Qg5? cb -+) there is windmill potential following 26...h6 (computer’s best apparently!) 27 Rg6 Qf6 28 Bf6 Kh7 29 Rg7 Kh8 and white should prevail
Apr-14-19  clement41: Still in DeFirmian’s line, in the event of 26...cb?? it is mate in two. But no windmill anymore as 26...cb 27 Rf7 Qf6 28 Bf6 Kg8 29 Rg7 Kh8 and white doesn’t have better than the perpetual because if 30 Rb7?? then 30..Rf6 31 Rb1 Raf8 (or ...Rc8) 32 h4 Rf1! 33 Rf1 (33 Kh2 Rb1 -+) Rf1 34 Kf1 b1Q and wins
