But I am quite sure, that it is a winning move, but Qh3 dould be winning also (most likely I think). The main variation after Rxe6 is the following one: 1.Rxe6 Qxe6 2. Rde1 Qf5 (Qd6 3.Bf4 h5 4. Qxc8 Rxc8 5. Bxd6 Bxd6 6. Bxd5+ +-) 3. Qxf5 gxf5 (all other moves loose instantly) 4. Bxd5+ Kg6 (only move): Now Shredder 8 gives + 2.36 at depth 25. This is not a prove but it seems unlikely that this position is not won for white. As i posted before I get +1.98 wiht a 24ply-search for 1. Qh3 in the startposition, which also seems rather convincing, that this move will lead to a win too. But I was too lazy to create variations here). regards Joachim P.S.: New game 2r1r3/p3b2p/1pn2pkB/3B1p2/3P4/P4N2/1P3PPP/4R1K1 w - - 0 1 Analysis by Shredder 8: 5.Bh6-f4 Kg6-g7 6.b2-b4 h7-h5 7.Bd5-e6 Rc8-d8 8.d4-d5 Be7-d6 9.Bf4xd6 Re8xe6 10.Re1xe6 +- (1.58) Depth: 13/13 00:00:00 5.Bh6-f4 Kg6-g7 6.b2-b4 h7-h5 7.Bd5-e6 Rc8-d8 8.d4-d5 Be7-d6 9.Bf4xd6 Re8xe6 10.Re1xe6 +- (1.58) Depth: 13/13 00:00:00 5.Bh6-f4 Kg6-g7 6.b2-b4 h7-h5 7.Bd5-e6 Rc8-d8 8.d4-d5 Be7-d6 9.Bf4xd6 Re8xe6 10.Re1xe6 +- (1.58) Depth: 13/13 00:00:00 5.Bh6-f4 Kg6-g7 6.b2-b4 h7-h5 7.Bd5-e6 Rc8-d8 8.d4-d5 Be7-d6 9.Bf4xd6 Re8xe6 10.Re1xe6 +- (1.58) Depth: 13/13 00:00:00 5.Bh6-f4 Kg6-g7 6.b2-b4 h7-h5 7.Bd5-e6 Rc8-d8 8.d4-d5 Be7-d6 9.Bf4xd6 Re8xe6 10.Re1xe6 +- (1.58) Depth: 13/13 00:00:00 5.Bh6-f4 Kg6-g7 6.b2-b4 h7-h5 7.Bd5-e6 Rc8-d8 8.d4-d5 Be7-d6 9.Bf4xd6 Re8xe6 10.Re1xe6 +- (1.58) Depth: 13/13 00:00:00 5.Bh6-f4 Kg6-g7 6.b2-b4 h7-h5 7.Bd5-e6 Rc8-d8 8.d4-d5 Be7-d6 9.Bf4xd6 Re8xe6 10.Re1xe6 +- (1.58) Depth: 13/13 00:00:00 5.Bh6-f4 Kg6-g7 6.b2-b4 h7-h5 7.Bd5-e6 Rc8-d8 8.d4-d5 Be7-d6 9.Bf4xd6 Re8xe6 10.Re1xe6 +- (1.58) Depth: 13/13 00:00:00 5.Bh6-f4 Kg6-g7 6.b2-b4 h7-h5 7.Bd5-e6 Rc8-d8 8.d4-d5 Be7-d6 9.Bf4xd6 Re8xe6 10.Re1xe6 +- (1.58) Depth: 13/13 00:00:00 5.Bh6-f4 Kg6-g7 6.b2-b4 h7-h5 7.Bd5-e6 Rc8-d8 8.d4-d5 Be7-d6 9.Bf4xd6 Re8xe6 10.Re1xe6 +- (1.58) Depth: 13/13 00:00:00 5.Bh6-f4 Kg6-g7 6.b2-b4 h7-h5 7.Bd5-e6 Rc8-d8 8.d4-d5 Be7-d6 9.Bf4xd6 Re8xe6 10.Re1xe6 +- (1.58) Depth: 13/13 00:00:00 5.Bh6-f4 Kg6-g7 6.b2-b4 h7-h5 7.Bd5-e6 Rc8-d8 8.d4-d5 Be7-d6 9.Bf4xd6 Re8xe6 10.Re1xe6 +- (1.58) Depth: 13/13 00:00:00 27kN 5.Bh6-f4 Kg6-g7 6.b2-b4 h7-h5 7.Bd5-e6 Rc8-d8 8.d4-d5 Be7-d6 9.Bf4xd6 Re8xe6 10.Re1xe6 +- (1.58) Depth: 13/13 00:00:00 27kN 5.Bh6-f4 Kg6-g7 6.b2-b4 h7-h5 7.Bd5-e6 Rc8-d8 8.d4-d5 Be7-d6 9.Bf4xd6 Re8xe6 10.Re1xe6 +- (1.58) Depth: 13/13 00:00:00 27kN 5.Bh6-f4 Kg6-g7 6.b2-b4 h7-h5 7.Bd5-e6 Rc8-d8 8.d4-d5 Be7-d6 9.Bf4xd6 Re8xe6 10.Re1xe6 +- (1.58) Depth: 13/13 00:00:00 27kN 5.Bh6-f4 Kg6-g7 6.b2-b4 h7-h5 7.Bd5-e6 Rc8-d8 8.d4-d5 Be7-d6 9.Bf4xd6 Re8xe6 10.Re1xe6 +- (1.58) Depth: 13/13 00:00:00 27kN 5.Bh6-f4 Kg6-g7 6.b2-b4 h7-h5 7.Bd5-e6 Rc8-d8 8.d4-d5 Be7-d6 9.Bf4xd6 Re8xe6 10.Re1xe6 +- (1.58) Depth: 13/13 00:00:00 27kN 5.Bh6-f4 Kg6-g7 6.b2-b4 h7-h5 7.Bd5-e6 Rc8-d8 8.d4-d5 Be7-d6 9.Bf4xd6 Re8xe6 10.Re1xe6 +- (1.58) Depth: 13/13 00:00:00 27kN 5.Bh6-f4 Kg6-g7 6.b2-b4 h7-h5 7.g2-g3 b6-b5 8.Bd5-e6 Rc8-d8 9.d4-d5 Nc6-e5 10.Nf3xe5 f6xe5 11.Re1xe5 Be7-d6 12.Re5xf5 Bd6xf4 13.Rf5xf4 +- (1.62) Depth: 14/24 00:00:02 738kN 5.Bh6-f4 Kg6-g7 6.b2-b4 b6-b5 7.Re1-c1 Nc6-b8 8.Rc1xc8 Re8xc8 9.Nf3-h4 Kg7-f8 10.Bd5-b7 Rc8-c3 11.Nh4xf5 Nb8-c6 12.a3-a4 Nc6xb4 13.a4xb5 ± (1.38) Depth: 15/26 00:00:07 2369kN 5.Bh6-f4 Nc6xd4 6.Nf3xd4 Be7xa3 7.Re1xe8 Rc8xe8 8.Nd4-f3 Ba3xb2 9.Nf3-h4+ Kg6-g7 10.Kg1-f1 a7-a5 11.Nh4xf5+ Kg7-f8 12.Nf5-d6 Kf8-e7 ± (1.33) Depth: 16/30 00:00:23 7471kN 5.Bh6-f4 Nc6xd4 6.Nf3xd4 Be7xa3 7.Re1xe8 Rc8xe8 8.g2-g4 Ba3xb2 9.g4xf5+ Kg6-g7 10.Nd4-e6+ Kg7-h8 11.Kg1-f1 Re8-c8 12.Kf1-e2 Rc8-c2+ 13.Ke2-e3 a7-a5 ± (1.31) Depth: 17/32 00:00:43 15168kN 5.Bh6-d2 Kg6-g7 6.Bd2-f4 h7-h5 7.b2-b4 b6-b5 8.Bd5-e6 Rc8-d8 9.d4-d5 Nc6-b8 ± (1.32) Depth: 17/43 00:00:53 19035kN 5.Bh6-d2 Kg6-g7 6.Bd2-f4 b6-b5 7.Bd5-e6 Rc8-d8 8.d4-d5 Nc6-e5 9.Nf3-d4 Ne5-d3 10.Be6xf5 Nd3xe1 11.Nd4-e6+ Kg7-f7 12.Ne6-g5+ f6xg5 13.h2-h4 g5xf4 ± (1.32) Depth: 17/43 00:01:03 22267kN 5.Bh6-d2 Kg6-g7 6.b2-b4 b6-b5 7.Bd5-e6 Rc8-d8 8.d4-d5 Nc6-e5 9.Nf3-d4 Ne5-c4 10.Bd2-c1 Nc4-e5 11.Nd4xb5 Ne5-d3 12.Re1-f1 Nd3xc1 +- (1.43) Depth: 18/36 00:02:07 44465kN 5.Bh6-d2 Kg6-g7 6.b2-b4 h7-h5 7.Bd2-f4 b6-b5 8.Re1-c1 Nc6-b8 9.Rc1xc8 Re8xc8 10.Nf3-h4 Kg7-f8 11.Nh4xf5 Be7xb4 12.a3xb4 +- (1.63) Depth: 19/36 00:03:26 71268kN 5.Bh6-d2 Kg6-g7 6.b2-b4 h7-h5 7.Re1-c1 Nc6-b8 8.Rc1xc8 Re8xc8 9.Nf3-h4 Be7-f8 10.Nh4xf5+ Kg7-g6 11.Bd5-e4 Rc8-d8 12.Bd2-f4 Kg6-f7 13.d4-d5 Rd8-e8 14.f2-f3 a7-a5 15.b4xa5 +- (1.69) Depth: 20/38 00:06:04 127926kN 5.Bh6-d2 Kg6-g7 6.b2-b4 a7-a5 7.Re1-e6 Nc6-d8 8.Re6xb6 a5xb4 9.a3xb4 Rc8-c2 10.h2-h4 Rc2-b2 11.g2-g3 Nd8-f7 12.Bd5-c6 Re8-c8 13.Kg1-h2 +- (1.69) Depth: 21/40 00:10:18 218263kN 5.Bh6-d2 Kg6-g7 6.b2-b4 a7-a5 7.Re1-e6 Nc6-d8 8.Re6xb6 a5xb4 9.a3xb4 Rc8-c2 10.h2-h4 Rc2-b2 11.g2-g3 h7-h5 12.b4-b5 Be7-b4 13.Bd2-e3 Nd8-c6 +- (1.84) Depth: 22/41 00:17:10 366131kN, tb=1 5.Bh6-d2 Kg6-g7 6.b2-b4 a7-a5 7.Re1-e6 Nc6-d8 8.Re6xb6 a5xb4 9.a3xb4 Rc8-c2 10.h2-h4 Rc2-b2 11.g2-g3 h7-h5 12.b4-b5 Be7-b4 13.Bd2-e3 f5-f4 14.Be3xf4 +- (1.79) Depth: 23/44 00:29:23 635510kN, tb=1 5.Bh6-d2 Kg6-g7 6.b2-b4 a7-a5 7.Re1-e6 Nc6-d8 8.Re6xb6 a5xb4 9.a3xb4 Rc8-c2 10.g2-g3 Nd8-f7 11.Kg1-g2 Nf7-d6 12.Bd5-c6 Re8-c8 13.b4-b5 +- (1.76) Depth: 24/46 00:55:18 1220985kN, tb=1 5.Bh6-d2 Kg6-g7 6.Bd2-f4 b6-b5 7.g2-g3 a7-a6 8.Kg1-g2 Nc6-a5 9.Bd5-e6 Rc8-c6 10.Be6-d7 Re8-d8 11.Re1xe7+ Kg7-f8 12.Bd7xc6 Kf8xe7 13.d4-d5 +- (2.01) Depth: 25/44 02:02:56 2697532kN, tb=4 5.Bh6-d2 Kg6-g7 6.Bd2-f4 b6-b5 7.g2-g3 b5-b4 8.Kg1-g2 a7-a5 9.Bd5xc6 Rc8xc6 10.d4-d5 Rc6-c8 11.d5-d6 b4xa3 12.d6-d7 Be7-f8 13.Re1xe8 +- (2.36) Depth: 25/47 02:26:20 3183940kN, tb=4
