I guess that you do not have chessmaster6000 It shows very small depthes in the first number chessmaster6000(ss=10) is even worse and often needs some minutes to get into depth 2. Chessmaster6000 shows 2 numbers. I guess that the first number is the brute force and the second number is search with null move pruning. depth 1/11 means 1 ply brute force and 11 plies with null move pruning+extensions so the main line is usually more than 11 plies. If you call search with null move pruning extensions you have no problem to see that chessmaster(ss=10) is searching usually less than 4 plies in the middle game. It is only a question of definitions Uri
