Kh5 is a >draw. The position is wrong, or the best move is wrong. OK thanks a lot for that info Bob. That makes me feel a lot better about my endgame analysis routines. I'll change the EPD data now. *grin* >>[D]4k3/4Pp2/5P2/4K3/8/8/8/8 w - - >> >>Suggested best move : Kf4 >>ColChess prefers : Kf5 (gives mate in 14 after 3 minutes' thinking, and at depth >>of 22 ply) >> > >This one is ok. Kf5 is a mate in 13. Kf4 is also a mate in 13. Oh OK. ColChess changed its mind to a mate in 13 as I played through the PV, so I'd tend to agree with that one. I suppose anyone with tablebases would easily get those two without any problems. I'm assuming that you didn't actually _calculate_ that mate in 18? :) Cheers, Col
