selectivity 0 for Fritz means no pruning.

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.
