But certainly the premise could be completely wrong :-) One interesting point, as discussed in the DartThought articles, is that most published self play experiments have been statistically insignificant. Another thing, perhaps fixed ply games aren't what we should be interested in since in real games searches are much deeper in the endgame. Fixed time would be better. > >Dave
