To summarize, you found: SP 2649 VP 2645 VT 2619 ST 2604 It's not a lot of games, but this is the exact same order in which I've ranked these four settings after now several thousand games from various sources. In the next Rybka release, there is a new default "moderately positional" setting which is about 75% SP and 25% VP. More importantly, a bunch of other things were changed and some new settings were added. Best regards, Vas
