Here is one: [D]5k2/5p2/2p2Bp1/1pppRB2/2bb2Q1/5Pq1/2PK1p2/8 w - - 0 1 Rybka 13b: 1.Qg4xg3 +- (18.23) Depth: 3 00:00:00 1.Qg4xg3 +- (310.00) Depth: 4 00:00:00 1.Qg4xg3 Bd4-c3+ +- (310.00) Depth: 4 00:00:00 Fritz 8: 1.Qg4xg3 f2-f1N+ 2.Kd2-e1 Nf1xg3 3.Bf5-d7 Bd4xe5 4.Bf6xe5 Kf8-e7 -+ (-3.49) Depth: 12/25 00:00:01 1867kN 1.Qg4xg3 f2-f1N+ 2.Kd2-e1 Nf1xg3 3.Bf5-d7 Bd4xe5 4.Bf6xe5 Kf8-e7 -+ (-3.49) Depth: 13/27 00:00:02 3496kN 1.Qg4xg3 f2-f1N+ 2.Kd2-e1 Nf1xg3 3.Bf5-d7 Bd4xe5 4.Bf6xe5 Kf8-e7 -+ (-3.49) Depth: 14/28 00:00:05 7371kN But all these are of course some meaningless situations, since Rybka is still beta and finally it would support underpromotions and make us stop fooling around with her.....:-)
