v.ShashChessGZ:
Stockfish patch
Simplify stats assignment for Pv nodes
This version is a release to demonstrate the superiority of ShashChess vs
Stockfish thanks to
a LTC (25+10) match on a 200 games suite on all common positional opening characteristics (thanks to italian expert Afro Ambanelli)
a test suite on 258 hard positions
