If it draws with rook and king vs king, you have something broken. It has specific code for such 'mating position'. I have had it play hundreds of games with itself, one side using egtb's, the other not. It has never failed to mate with KR vs K easily. Not "optimally" usually, but quickly and easily. IMHO Crafty is not a "stupid program" in endings. It handles itself pretty well most of the time. Unless something is broken or mis-configured. If you have a log.nnn file where it couldn't win KR vs K, that might tell what was happening.
