Analysis by CM9000 (Junior personality) on slow Athlon 700 MHz system: Time Depth Score Positions Moves 0:05 1/6 -2.00 716041 26...c5+ 27.dxc6ep b5 28.Bd3 Nexc6+ 29.Kc3 Bg7+ 30.Kd2 Rxd3+ 31.Ke1 Rxd1+ 32.Rxd1 Bxb2 33.Rxd6 Ne5 0:18 1/7 -1.97 2427668 26...c5+ 27.dxc6ep b5 28.Bd3 Nexc6+ 29.Kc3 Bg7+ 30.Kd2 Rxd3+ 31.Ke1 Bxb2 32.Nf4 Rxd1+ 33.Rxd1 Bc3+ 34.Kf1 Re8 1:01 1/8 -2.07 7993313 26...c5+ 27.dxc6ep b5 28.Bd3 Nexc6+ 29.Kc3 Bg7+ 30.Kd2 Rxd3+ 31.Ke1 Bxb2 32.Nf4 Rxd1+ 33.Rxd1 Be5 34.Kf1 Rf8 3:13 1/9 -2.01 25627286 26...c5+ 27.dxc6ep b5 28.Bd3 Nexc6+ 29.Kc3 Bg7+ 30.Kd2 Rxd3+ 31.Ke1 Bxb2 32.Nf4 Rxd1+ 33.Rxd1 Bc3+ 34.Kf1 Re8 35.a3 It appears that 26... c5+ is indeed a winning move. After forcing 26... Bg7, the following analysis ... Time Depth Score Positions Moves 0:28 1/8 0.00 3500329 27.Ng1 c5+ 28.dxc6ep Ned3+ 29.e5 Bxe5+ 30.Kc4 b5+ 31.Kxb5 Rb8+ 32.Ka4 Nxb2+ 33.Ka3 Nc4+ 34.Ka4 Nb2+ 1:39 1/9 -0.68 12110164 27.Ng1 Rxg3 28.Ne2 Rf3 29.Ng1 c5+ 30.dxc6ep Ned3+ 31.Kc4 b5+ 32.Kxb5 Rb8+ 33.Ka4 Nxb2+ 34.Ka3 Nxd1 35.Rxd1 6:58 1/10 -0.68 51818694 27.Ng1 Rxg3 28.Ne2 Rf3 29.Ng1 c5+ 30.dxc6ep Ned3+ 31.Kc4 b5+ 32.Kxb5 Rb8+ 33.Ka4 Nxb2+ 34.Ka3 Nxd1 35.Rxd1 15:41 1/11 -0.75 117443487 27.Ng1 Rxg3 28.Ne2 Rf3 29.Ng1 c5+ 30.dxc6ep Ned3+ 31.Kc4 b5+ 32.Kxb5 Rb8+ 33.Ka4 Nxb2+ 34.Ka3 Nxd1 35.Bxd1 Bxa1 36.c7 Bb2+ 37.Kxb2 Even if this is not a draw (I'm too tired to analyze it myself tonight), it is not as convincing as 26 ... c5+ is.
