Just a little remark.

I had the following line in my book:
1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 Bc5 5.Bxf7

An exotic line in a book build upon some GM games. All GM's played 5.Bxf7 here
as White but when I lunched the engine on ICC I saw that most players would play
5.Nxf7 instead.
Check your engine score here and after the right 5...Bxf2! and see if it will
resign if it play as Black.

The statistics say 73% score for Black!

If you also use movecount in the resign algorithm you could adjust the resign
score based upon opponent rating instead of having it constant.
There is two factors to consider: You don't want to resign to fast, and you
don't want to bother your opponent so that he don't comes back to play against
your engine.
