[Monday update: Hm – what about 28.f4 Qe7 29.Be2 ? Can Black save his h-file pieces after 29…fxg4 30.Bxg4 ? This is a ‘car line’, meaning I don’t have a board to check it. Humph.]
Now that we’ve prattled on about how IMs and GMs make mistakes, IM Foygel has kindly reminded me that experts make many more.

21.Bf1 Bb7 [Afterwards Igor noted he should have just played 21…Bxf1 22.Kxf1 Rg6 23.Ne2 Nxg3 24.Nxg3 Bh4]
22.Bd3 Rg6 23.g4 [Same concept as before : 23.Ne2 Nxg3 24.Nxg3 Bh4-+ , but now the Bd3/Rg6 pin allows White to keep hanging on for a bit]
23…Bh4 24.Qh2 Qg5 [See diagram.]
[White slightly outnumbered on kingside, yes?] 25.Nd1 Rf8 26.Rc2 e5 27.Rg2 e4 28.gxh5 Qxg2+ 29.Qxg2 Rxg2+ 30.Kxg2 exd3 31.Rc1 f4 32.Rc7 Rf7 33.Rxf7 Kxf7 34.Bc3 fxe3 35.Nxe3 Ke6 36.Nf1 Bc6 37.Bd2 Bf6 38.Bc3 Be8 39.Kf2 Bxh5 40.Ne3 Bh4+
[Whew, not mated. Funky ending, slightly problematic for Black to win because he can’t let it go into bishops of opposite color. I try to just sit tight and keep the Black king out. Guess I shoulda tried to keep the bishop out too w/ 42.b4. Not clear to me if this can be held. At any rate, not by me and not against him :)] 41.Kg2 Be7 42.Kg3 Ba3 43.Kf2 b5 44.Nd1 Bc1 45.Ne3 a6 46.Nd1 Kd7 47.Ne3 Kc6 48.Nf1 Kb6 49.Ne3 Bf7 50.Nf1 a5 51.Ke1 Bg6 52.Kf2 d2 53.Bxd2 Bb2 54.Ke3 Bb1 55. a4 Bc2 56.axb5 Bxb3 0-1
So – last game to finish at the club – 11:30pm, four solid hours of play.
I’ve had several friends who were good chessplayers but gave it up for bridge. They said in bridge, you make a mistake, you lose the hand, you get dealt a new hand and start afresh; in chess, you make a mistake, you suffer for many hours and then lose.
