I think I´ve found a little Tablebase-Bug in Crafty 16.15. Look at this position for example: wKe5, e2, d2; bKa8, d5. After Kd5: there is a postion with PP vs P on the board and (with installesd tablebases!) I expected Crafty to show a mate in several moves. But he is calculating and calculting and shows after minutes something about +10. After Kd5: he announces a correct mate. This phenomenon took place when there is a pawn at the row next to the black pawn (Example: black f-pawn with white e or/and g-pawn) and the white pawn is at its beginning field. When you move this white pawn one or two squares above Crafty has no problem with showing the mate. Is it a problem of Crafty of 16.15 or a problem belonging to Craftys running under the Fritz GUI? Best wishes Helmut
