[D]r1bqkbnr/1ppp1ppp/p1N5/4p3/4P3/5N2/PPPP1PPP/R1BQK2R b KQkq - 0 1 If you type "d" in this position the Fritz GUI knows that it can't just move the bishop to d6, as the pawn isn't pinned by the knight. And if you type dxc it also knows that it should take the pawn on c6 with its d-pawn. You found another potential bug here actually - if you type d7 (upper or lower case doesn't matter) it will move its queen to e7 - clearly there is a natural conflict with its support for both its own very short and the long notation form here, which makes me guess that entering moves by keyboard is just an ancient feature, that isn't really supported anymore.
