Here is Deep Fritz's opinion at move 49 I did not analyze the relevant position to see which side is winning but even at move 49 it is not clear for chess programs that Fritz is losing I think that in this kind of unclear positions outsearching the opponent should be more important. I did not analyze this position to decide if white or black is better but it may be interesting to do ply tournaments between Tiger and Fritz in order to see what happens(I accept deep search to dominate here but I may be wrong) It is interesting to see if there is a depth of tiger when tiger starts to win against every depth of Fritz Chess Tiger 14.6 - Fritz 8/5p1k/pp4pp/4p3/n2p4/8/2RN3P/4K3 b - - 0 1 Analysis by Deep Fritz: 49...e4 50.Nxe4 µ (-1.03) Depth: 1/3 00:00:00 49...Nc3 50.Nf3 -+ (-2.47) Depth: 2/4 00:00:00 49...Nc3 50.Nf3 -+ (-2.47) Depth: 2/4 00:00:00 49...Nc3 50.Nf3 -+ (-2.47) Depth: 2/4 00:00:00 49...Nc3 50.Nf3 -+ (-2.47) Depth: 2/4 00:00:00 49...Nc3-- -+ (-2.16) Depth: 3/7 00:00:00 49...Nc5! -+ (-2.19) Depth: 3/7 00:00:00 49...Nc5! -+ (-2.19) Depth: 3/7 00:00:00 49...Nc5! 50.Nc4 d3 -+ (-2.59) Depth: 3/7 00:00:00 49...Nc5 50.Nc4 d3 51.Rd2 -+ (-2.50) Depth: 4/9 00:00:00 49...Nc5 50.Nc4 Nd7 51.Rb2 b5 -+ (-2.41) Depth: 5/9 00:00:01 1kN 49...Nc5 50.Nc4 e4 51.Nxb6 Nd3+ 52.Ke2 Kg7 -+ (-2.38) Depth: 6/11 00:00:02 4kN 49...Nc5 50.Nc4 e4 51.Nxb6 Nd3+ 52.Ke2 Kg7 53.Nd5 -+ (-2.28) Depth: 7/15 00:00:13 12kN 49...Nc5 50.Nc4 e4 51.Nxb6 Nd3+ 52.Ke2 Kg7 53.Rc4 Nf4+ 54.Kd2 -+ (-2.16) Depth: 8/17 00:00:24 31kN 49...Nc5 50.Nc4 e4 51.Nxb6 Nd3+ 52.Kd2 Kg7 53.Rc4 Ne5 54.Rxd4 Nf3+ 55.Ke3 -+ (-1.88) Depth: 9/19 00:00:51 86kN 49...Nc3! -+ (-1.91) Depth: 9/20 00:00:59 159kN 49...Nc3! 50.Nc4 e4 51.Nxb6 f5 52.Nd7 g5 53.Nf8+ Kg8 54.Ne6 -+ (-2.03) Depth: 9/20 00:00:59 169kN 49...Nc3 50.Nc4 e4 51.Nxb6 Kg7 52.Rd2 Nb5 53.Nd7 f5 54.Nc5 -+ (-1.84) Depth: 10/19 00:01:00 223kN 49...Nc5! -+ (-1.88) Depth: 10/20 00:01:00 253kN 49...Nc5! 50.Nc4 Nd3+ 51.Kd2 e4 52.Nxb6 Ne5 53.Ra2 Nf3+ 54.Ke2 d3+ 55.Ke3 -+ (-1.97) Depth: 10/20 00:01:00 275kN 49...Nc5-- -+ (-1.66) Depth: 11/22 00:01:01 520kN 49...Nc5-- -+ (-1.66) Depth: 11/22 00:01:01 550kN 49...Nc3! -+ (-1.69) Depth: 11/24 00:01:01 702kN 49...Nc3 50.Nc4 e4 51.Nxb6 Kg7 52.Rc1 f5 53.Ra1 g5 54.Rxa6 f4 55.Nd7 -+ (-1.41) Depth: 12/23 00:01:03 2066kN 49...Nc5! -+ (-1.44) Depth: 12/24 00:01:03 2141kN 49...Nc5! 50.Nc4 Nd3+ 51.Ke2 e4 52.Nxb6 Ne5 53.Ra2 Nf3 54.Nd5 Kg7 55.Rxa6 -+ (-1.53) Depth: 12/25 00:01:04 2490kN 49...Nc5 50.Nc4 Nd3+ 51.Ke2 e4 52.Nxb6 Ne5 53.Ra2 Nf3 54.Nd5 Kg7 55.Rxa6 -+ (-1.47) Depth: 13/25 00:01:07 4568kN 49...Nc5 50.Nc4 Nd3+ 51.Ke2 e4 52.Nxb6 Ne5 53.Rc7 Kg7 54.Nc4 Nf3 55.Nd6 µ (-1.19) Depth: 14/27 00:01:15 9271kN 49...Kg7! µ (-1.22) Depth: 14/28 00:01:22 13356kN 49...Kg7! 50.Nf3 e4 51.Nxd4 Nc5 52.Kd2 Kf6 53.Ke3 Ke5 54.Nc6+ Kd6 55.Nd8 µ (-1.34) Depth: 14/30 00:01:32 20308kN 49...Kg7 50.Nf3 e4 51.Nxd4 Nc5 52.Kd2 Kf6 53.Rb2 Na4 54.Rb1 Kg5 55.Ke3 µ (-1.25) Depth: 15/29 00:01:47 29387kN 49...Kg7-- µ (-0.94) Depth: 16/32 00:02:33 57094kN 49...Kg7-- µ (-0.94) Depth: 16/32 00:02:38 60435kN 49...Nc3! µ (-0.97) Depth: 16/32 00:02:44 64289kN 49...Nc3! 50.Nc4 e4 51.Nxb6 Kg7 52.Nd7 f5 53.Nc5 Kf6 54.Rd2 Ke5 55.Nxa6 µ (-1.03) Depth: 16/32 00:02:51 68302kN 49...Nc3 50.Nc4 e4 51.Nxb6 Kg7 52.Nd7 f5 53.Nc5 Kf6 54.Nxa6 f4 55.Nb4 µ (-0.97) Depth: 17/31 00:05:02 149400kN 49...Nc3 50.Nc4 e4 51.Nxb6 Kg7 52.Nd7 f5 53.Rd2 d3 54.Nc5 Kf6 55.Nxa6 µ (-0.88) Depth: 18/35 00:09:28 315352kN 49...Nc3 50.Nc4 e4 51.Nxb6 f5 52.Rb2 g5 53.Nd7 a5 54.Ne5 f4 55.Rb7+ µ (-0.91) Depth: 19/36 00:18:35 660541kN, tb=5 49...Nc3 50.Nc4 e4 51.Nxb6 f5 52.Rb2 Kg7 53.Rb4 d3 54.Rc4 Ne2 55.Nd5 µ (-0.84) Depth: 20/37 00:38:59 1435080kN, tb=15 49...Nc3 50.Nc4 e4 51.Nxb6 f5 52.Rc1 f4 53.Nc4 Nd5 54.Ne5 g5 55.Rc6 ³ (-0.66) Depth: 21/39 02:34:49 5904271kN, tb=179 49...Nc3 50.Nc4 e4 51.Nxb6 f5 52.Rc1 Kg7 53.Ra1 e3 54.Rxa6 f4 55.Nc4 ³ (-0.59) Depth: 22/42 05:20:06 12265255kN, tb=498 49...Kg7! ³ (-0.63) Depth: 22/42 06:23:16 14688877kN, tb=607 (Blass, Tel-aviv 04.11.2001) Uri
