The users here are (typically) owners of multiple chess programs (for various reasons). And many of them are interested in finding "the best" one of them all. This, of course, leads to people who keep upgrading and testing new versions against old versions, etc. etc. etc.... The OTHER 95+% of Chessmaster owners have ONLY Chessmaster (although they may have more than one version), and my testing is intended for them. All I'm interested in is finding the best OVERALL settings CONFINED to the Chessmaster world. If some settings can be found that are clearly equal or stronger over ALL time controls and on ALL hardware (which is what the default settings are intended to be), then I will definitely sit up and take notice (as I have done with CM_Utzinger). But, if someone creates a personality that is fantastic at blitz but weak at longer time controls, then I am not interested. jm
