As previously posted, the overall >strength of the personally known chessmasters in asending order are: cm7k, cm8k, >ckm6k, and cm55. And btw, who said that move is a "weak" move? I used CM6777 for a long time, and it is definitely good. I've had less experience with the CM8000 analog so am reserving judgement. However I feel that increasing the selectivity to maximum (or beyond) is definitely a plus. The main problem I had with the CM6777 settings was that it overvalues the Queen (in my opinion) in some situations. For example it heads for endgames of Q vs. R + piece + P, where the Queen can only draw. So I'm inclined to value the Queen somewhat less, relative to that particular combination of pieces. Of course you must also consider whether it is properly valued vs. a pair of Rooks, and vs. 3 pieces. A compromise is required. I am currently using piece values which I believe are more conservative than CM6777, but are probably an improvement over the defaults: Q=9.3, R=5, B=3.2, N=3.1, P=1.0. As for the other settings, I use half of CM6777's deviations from defaults: Attacker/Defender +1, Contempt for Draw +0.1, Material/Position -1, Control of Center 101, Mobility 102, King Safety and Pawns Weakness 117. Everything else has the default settings, except I set selectivity to 32 with a hex editor. Call it the William Penn personality, I guess, because it's fairly original. WP
