Hi,

No, I'm not printing Alpha. I'm printing the real value of the move. If I take
the alpha beta cuts from mini-max I get the exact same values I posted.

What's the PV of a move ? The evaluation of just that move not considering
anything else ?
I've done that and the results were what I expected, they are diversified.
(I increase the pawn value by 10% per each row it crosses)
