Chessmaster6000 often can see at depth 3 things that other programs cannot see at depth 10. The brute force depth of chessmaster6000 is often not more than 4 at tournament time control. Chessmaster show 2 numbers and I understand that the first number is the brute force depth and the second number is the selective search depth. The default personality(tested by ssdf) has the parameter ss=6 If I see numbers like 4/10 the meaning(if I understand right) is that it looks at everything at depth 4,almost everything at depth 10 and does also extensions after it.
