CM9000 is known for doing a lot of extensions so it is not a good example. It often show brute force of 1 or 2 in analysis. it may shows after some minutes depth 2/10 when 2 is the brute force depth(no null move pruning),10 is the minimal extension depth(it may do more extensions)and a mate in 17 score that other programs may need depth 20 to find.
