- - By benben (***) [au] Date 2008-11-22 08:26
Rybka mates in 3 moves instead of 2, but once you use infinite analysis it sees the mate in 2(Qc2). Fritz on the other hand does not see mate in 2 at all...

Hi,
    When I put the position in at first R3 showed mate in 2 at 7ply with Qc2 but then after a few seconds changed to mate in 3 at 8ply also with Qc2 lol ... R3 Dynamic did exactly the same as did R3 Human .... Zap Mex 2 shows mate in 2 correctly as does Cyclone 2

Regards

In my Portable PDA of pocket  "Palm Hiarcs 9.7" it  gives mate in 2 to the instant (Qc2 Rxc2 Rh7 +)
