CM9000 looks nice indeed. Takes Deep Fritz 7 quite bit longer on hardware over twice as fast.. here's DF7's analysis (w/ 350mb hash) after an hour on an AthlonXP 1900+ (1.6) @ 1.8GHz...

Some sort of knowledge that needs to be implemented perhaps? Deep tactics/positional stuff? I don't play chess myself so I can't tell how this position differs from any other position. Thanks (and to the others who did also) for posting the eval of your engine.
