I do not know but I looked at a game of the real crafty with some tablebases (1 hour per game on 2 K6-350 against Junior5) and I found that Crafty16.6 as an engine for Fritz found all the moves of the game before the endgame of KRB vs KRPP on my P200MMX in less than 11 minutes. It needed almost 11 minutes for one of the moves and less than 6 minutes(usually less than 1 minute) for the other moves. I think that there is no big difference between the real crafty and the engine for fritz(maybe there is a difference of 20-30 rating). Uri
