Here are my results on a P2/300. Rxd5+ draw score in 2 seconds, switches to Bg5 (evaluates as slightly better) at 20 seconds, switches back to Rxd5+ at 2:38, resolving to +1.52, has +2.30 after an hour. Superficially, looks like Rxd5+ wins a queen for a rook and a minor. I didn't play through it but it seems like this is the kind of queen that wins, too. bruce -------------- PV 00:00:01.370 6 -81 [wrong] Bf4 Qf5 Qxf5 Bxf5 Rxb7 Rc8 O-O PV 00:00:01.870 6 -78 [right] Rxd5+ PV 00:00:01.911 6 -56 [right] Rxd5+ PV 00:00:02.176 6 -51 [right] Rxd5+ Nxd5 Qxd5+ Ke7 Qc5+ Kxf6 Qg5+ Kf7 Bh5+ Ke6 Bg4+ Kf7 Bh5+ PV 00:00:04.600 7 -51 [right] Rxd5+ Nxd5 Qxd5+ Ke7 Qc5+ Kxf6 Qg5+ Kf7 Bh5+ Ke6 Bg4+ Kf7 Bh5+ PV 00:00:11.252 8 -51 [right] Rxd5+ Nxd5 Qxd5+ Ke7 Qc5+ Kxf6 Qg5+ Kf7 Bh5+ Ke6 Bg4+ Kf7 Bh5+ PV 00:00:20.853 8 -48 [wrong] Bg5 PV 00:00:32.156 8 -1 [wrong] Bg5 PV 00:00:44.341 8 8 [wrong] Bg5 Be6 Nxd5 b6 Qf3 Rc8 Bxc4 Re8 PV 00:01:58.759 9 17 [wrong] Bg5 Qa2 Rxd5+ Kc7 Bf4+ Kb6 O-O Rf8 Rd6 Bf5 Rc1 Bd3 PV 00:02:38.397 9 20 [right] Rxd5+ PV 00:02:48.090 9 58 [right] Rxd5+ PV 00:03:06.777 9 152 [right] Rxd5+ Nxd5 Qxd5+ Ke7 Qc5+ Kxf6 Qg5+ Kf7 Bh5+ Ke6 Bg4+ Kf7 Qd5+ Kf8 Bh6+ Ke8 Bh5+ Qg6 Bg7 c2 O-O Ne7 Bxg6+ hxg6 PV 00:04:43.495 10 152 [right] Rxd5+ Nxd5 Qxd5+ Ke7 Qc5+ Kxf6 Qg5+ Kf7 Bh5+ Ke6 Bg4+ Kf7 Qd5+ Kf8 Bh6+ Ke8 Bh5+ Qg6 Bg7 c2 O-O Ne7 Bxg6+ hxg6 Qxc4 PV 00:10:54.276 11 202 [right] Rxd5+ Nxd5 Qxd5+ Ke7 Qc5+ Kxf6 Qg5+ Kf7 Bh5+ Ke6 Bg4+ Kf7 Qd5+ Kf8 Bh6+ Ke8 Bh5+ Qg6 Bg7 c2 O-O Ne7 Bxg6+ hxg6 Qxc4 PV 00:26:16.095 11 210 [right] Rxd5+ Nxd5 Qxd5+ Ke7 Qc5+ Kf7 Bh5+ Kg7 Qg5+ Qg6 Bxg6 cxd2+ Qxd2 Kxg6 Ne4 Re8 Qg5+ Kf7 PV 01:03:18.982 12 230 [right] Rxd5+ Nxd5 Qxd5+ Ke7 Qc5+ Kf7 Bh5+ Kg7 Qg5+ Qg6 Bxg6 cxd2+ Qxd2 hxg6 Qc3 Rd8 Ne8+ Kf7 Nc7 Rb8 Qxc4+ Kg7 Qc3+ Nd4 O-O
