I have seen large positional scores out of fritz, >which suggests (to me) that mtd(f) could cause some problems... It means there's a lower granularity of values, so less (re-)searches are required to arrive at the score. I have believed for some time that this is a correct decision, because I don't have confidence in the precision of even centipawn evaluations (much less the millipawn evaluations that Diep years ago when Vincent based mtd techniques heavily). I didn't know that Fritz actually had done it, though. The range of positional scores is relevant for lazy evaluation schemes, but I think that issue is pretty well handled by Don Dailey's recommendation. Dave
