[Roman Bonzon & Fritz 11]

1.d4 e6 2.Nf3 c5 3.d5 exd5 4.Qxd5 Nf6 5.Qe5+ Be7 6.c4 Nc6 7.Qc3 0-0 8.Nbd2 d5 9.e3 Bf5 10.Bd3 d4 11.exd4 cxd4 12.Qb3 Bxd3 13.Qxd3 Nb4 14.Qb3 Bc5 15.0-0 d3 16.Ne1 Re8 17.a3??
[Fritz 11 17.Qd1 and now if 17...Rxe1 18.Rxe1 Nc2 19.Nb3 Nxe1 20.Qxe1 ]

[Fritz 11 17...Bxf2+!! 18.Kh1 (18.Rxf2 Rxe1+ 19.Nf1 Nc2 ) 18...Bxe1 19.axb4 ]

[Fritz 11 18.Ndf3 Bxf2+ 19.Kh1 Bxe1 20.Bg5 f6 21.axb4 fxg5 22.Nxe1 d2 23.Nf3 Ne3 24.Rfd1 Nxd1 25.Qxd1 ]

[Fritz 11 18...Rxe1!! and if 19.bxc5 Qh4 20.h3 Qxf2+ ]

[19.Kh1 Rxe1 20.Rxe1 Bxe1 21.Nf3 d2 ]

[Fritz 11 19...Rxe1+!! Mark and Joe also found this at the postmortem 20.Nf1 Qd4 21.Be3 Qxe3 22.Rxe1 Qxf2+ ]

and now White is perfectly safe, and has 3 pieces for a rook

[20...Re1+ 21.Nf1 is something I considered during the game, and also thought about in the postmortem 21...Nxf2 22.Nxf2 Rae8 23.Qd3 ]

21.Nxf2 Re3
[21...Re2 22.Qf3 ]

looked good at the time, but Fritz thinks [22.Qd1 Rae8 23.Nf3 is much better for White]

[Fritz 11 22...Re2! the Black queen is immune because of the back-rank threat 23.Be3 is the only reply 23...Qxe3 24.Qxe3 Rxe3 presenting White with a very tough challenge]

23.Nxd4 Re8 24.Kf1
[Fritz 11 24.Bd2 is so much more precise 24...Rxb2 25.Bc3 ]

24...Rxb4 25.b3 Rb6 26.Rxa7 Rd6 27.Bb2 Rd7 28.c5 Rd5 29.b4 Rde5 30.g3 h6 31.Rxb7 Re1+ 32.Kg2 Rb1 33.Bc3 Rc1 34.Bd2 Rc4 35.Rd7 Ra8 36.c6 Ra2 37.Bf4 Kh7 38.c7 Ra8 39.Rd8 1-0
