Hello Dave,

About your comment about Rybka's hash size setting, I get at least different
results setting the hash size for Rybka in ChessPartner, so I'm assuming that
parameter does work there. What problems did you observe? Maybe I missed some
posts...

Just a quick test in Kevin Burcham's, superprogrammer, testposition:

[D]3qbr1k/r3p3/2p1Pp1b/ppN2Pp1/P1pP4/2P2B2/2Q3KP/1R3R2 b - - 0 1
