Rf2! is the best move, and that is backed up by crafty, TCB, and HIARCS. >Anyway I dont see the problem with Rf2!. Rf2 is not the best move of Crafty18.1 It prefers Rxb3 with evaluation of 0.00 at depth 15 After Rf2 Crafty can see a clear advantage for white (1.54 pawns at depth 13 and 1.68 at depth 14) The problem is that tiger does not know that rook and a bishop with no pawns usually cannot win. It is a known problem of tiger and it is not news. Uri
