If I give it 1 option then it cannot see the mate even at depth 19 3)if I give Fritz5(16 bit) the all study and not only this simple position then it cannot find evaluation more than 0.00 The all study: 1R3b2/5ppQ/6Pp/6PP/R6P/P7/7K/2q1k3 w - - 0 1 1.Rb1 Qxb1 2.gxf7 Qxh7 3.g6 Qh8 4.Re4+ Kd2 5.Re8 Kc3 6.Kg2 Kc4 7.a4 Kc5 8.a5 Kc6 9.a6 Kb6 10.Ra8 Kc7 11.Kf3 Kb6 12.Ke4 Kc7 13.Kd5 Kb6 14.a7 Kb7 15.Re8 Kxa7 16.Kc6 If I give Fritz5(16 bit) only the position before 16.Kc6 then the evaluation of Fritz5(16 bit) is: 1.75/13,1.44/14,1.13/15, 0.81/16, 0.50/17,0.19/18 0.50/19 0.19/20 0.50/21 If I give the game the evaluation is different 2.22/14, 1.91/15,1.59/16,1.28/17,0.97/18,0.66/19,0.34/20 There is no reson for that because the last move was a capture so the position cannot repeat twice.
