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.
