You posted the same position March 29 and April 2, under the same title. Only this time you put the white knight in it's right place instead of the black knight as in this original thread. I already replied to this once today on the other thread line: Fritz 5.32 As soon as I set it up, I get to the board and see: 1) Qd8 +-(#2) depth 2/6 00:00:00 Fritz 5.32 Sees it fairly easy I would say :-) UltraB
