1.d4 Nf6 2.Nf3 e6 3.c4 d5 4.g3 c6 5.Bg2 Bd6 6.0-0 Nbd7 7.Nbd2 0-0 8.b3 e5 9.cxd5 cxd5 10.dxe5 Nxe5 11.Bb2 Qe7 12.Nxe5 Bxe5 13.Bxe5 Qxe5 14.Nf3 Qb2 15.Qd3 Bd7 16.Rfb1 Qa3 17.Nd4 Rac8 18.Rd1 Rfe8 19.Nc2 Qc5 20.Ne3 Be6 21.Qd4 Red8 22.Bf3 a5 23.Rd2 Kf8 24.Rad1 b6 25.Qf4 Qb5 26.Nf5 Bxf5 27.Qxf5 Rc5 28.Qf4 Re8 29.Kg2 Ne4?

 

 

Now the d-file opens. [Black should just wait and see with e.g. 29...h6 ]
30.Bxe4 dxe4 [The lesser evil was 30...Rxe4 31.Qd6+ Re7 32.e3! when White only wins a pawn on d5.]
31.Rd7 Rf5 32.Qd6+ Kg8 33.Re7 e3 This attempt to fish in muddy waters nearly would have succeeded. [Objectively better, however, was 33...Rxe7 34.Qxe7 h6 ]

34.a4??

Throwing away the win! [Correct was 34.Rxe8+ Qxe8 35.Qxb6 - answer B - and the threat Rd8 winning the queen decides, since 35...exf2 can be met by the cool 36.Kf1! ]

 

34...Qe5?? Throwing away the draw! [The surprising rescue was 34...Rxf2+ 35.Kg1 Rg2+! 36.Kxg2 (36.Kh1 Rxh2+ changes nothing) 36...Qxe2+ 37.Kh3 Qh5+ 38.Kg2 Qe2+ with perpetual check.]
35.Rxe5 Rfxe5 36.Qxe5 1-0
