Then I ask you to think it through again. Deeper search with bad eval will often have to change it mind because the search depth will refute the choices made based on positional knowledge. Good eval will mean that there is on average less earlier choices to refute by deeper search, so it won't change it's mind as much. Better choices earlier must lead to fewer change-of-minds. Jesper
