Chessmaster 9000 (CM_SKR personality) seems to think that White is marginally ahead after 13...Bxa2 (+0.17). The engine thinks that 17...Bd7 was not as good as 17...Rxd1 18.Rxd1 Qe8, with a difference of about a half-pawn. The engine PREFERS 22...Bf5, with a score of -0.04 (this is on a P4-2.4): Time Depth Score Positions Moves 0:00 1/3 0.14 1690 22...Re8 23.Bxg7 Kxg7 24.Qc3+ Ne5 25.fxe5 Bxe5 0:00 1/3 -0.18 2089 22...Bh3 23.Be4 Qe6 24.b4 0:00 1/3 -0.23 2289 22...Bf5 23.e4 Bg4 0:00 1/3 -0.27 3246 22...Bg4 23.Ne3 Be6 24.Nd5 0:00 1/4 -0.28 5734 22...Bg4 23.Bxg7 Kxg7 24.Qc3+ Kg8 25.Nf6+ Kf8 26.Nxh7+ Kg8 0:00 1/4 -0.54 6832 22...Bf5 23.e4 Bg4 24.Rd3 a5 0:00 1/5 -0.35 16065 22...Bf5 23.e4 Bg4 24.Rd3 a5 25.Be1 0:00 1/6 -0.35 55278 22...Bf5 23.e4 Bg4 24.Rd3 a5 25.Be1 0:00 1/7 -0.36 165532 22...Bf5 23.Qb3 a6 24.Bxg7 Kxg7 25.Qc3+ Kg8 26.Nf6+ Kf8 27.Bxc6 bxc6 28.Qxc6 0:01 1/8 -0.39 369218 22...Bf5 23.e4 Bg4 24.Rd3 a5 25.Be5 Bxe5 26.fxe5 Re8 0:03 1/9 -0.21 914137 22...Bf5 23.e4 Bg4 24.Rd3 Ne7 25.Ne3 Bh3 26.Bf3 c5 27.f5 0:15 1/10 -0.28 3637456 22...Bf5 23.e4 Bg4 24.Rd3 Be6 25.Rdd1 a5 26.f5 Bxd5 27.Rxd5 0:33 1/11 -0.18 7681638 22...Bf5 23.e4 Bg4 24.Rd2 Bh3 25.Bxg7 Bxg2+ 26.Kxg2 Kxg7 27.Qc3+ Kg8 28.Nf6+ Kf8 29.Nxh7+ Kg8 1:32 1/12 -0.04 24021139 22...Bf5 23.e4 Bg4 24.Rd2 Ne7 25.e5 Nxd5 26.Rxd5 Be7 27.Rxd8+ Bxd8 28.Bb4 c6 29.Bd6 The engine slightly prefers 24...Ne7 to Be6, because of 25.f5!, which the engine gives a score of +0.58. But ParSOS played 25.e5 instead.... But 32...Nb4 looks like the losing move. The engine gives 32...Bb4 a score of +0.02. But after 32...Nb4, the score is +2.00 and climbing.... Finally, after 35...Nd5, the engine announces Mate in 14 after 19 seconds!
