But copying either is really copying the >"personality" of the program... I think that by that logic a lot of programs copied the "personality" of Crafty even if they do not use bitboards. Your words imply that it is better if I continue not to evaluate correctly KRP vs KR endgames because if I evaluate them correctly then I copy the personality of Crafty that also knows to evaluate them correctly. I do not think to copy ideas without testing and it is possible that something that is productive for crafty is not productive for movei because it is already evaluated by another term but I think that complaining too much about copying ideas from crafty is not productive and it only can cause people to leave chess programming.
