Seems odd, but as long as it wins, I have no problems with it. :) > >Jeremiah one better than that... while debugging 16.0, I broke the multiple directory stuff. And played a bunch of games on ICC not knowing this. I was watching it play a KQNP vs KP ending... and it promptly checked 3 times with the queen, forcing the opponent to the edge of the board, then it checked one more time, but in a way that forced the move KxQ, then it promoted the pawn to a knight and announced a mate in 86 moves in a KNN vs KP ending. The problem was that most of the tablebases were in the inaccessible directory so it only had the KNNK* files to use... To say I was astounded would be an understatement... :)
