AFAIK, that is the correct value for it to return. As per the EPD(?) specifications, mate value should be 327.67 (I think). Mate in 2 (3 ply) would return a score of 327.65, and so on. Being mated in 1 (On the second ply) should return a score of (-)327.66, and so on. Someone please correct this if I'm wrong. :) I haven't fully read the documentation, but it is what I understand from previous conversations, and from Crafty's handling of this. Jeremiah
