This is the day i can“t be more proud of this game, because Gandalf 4.32h shows
me the refutation 23.Nxf4!!.
White has after exf4 24.Qxf4 the idear of Qh2! and Bg3! followed by e4-e5 and
d5-d6 with a pawnroller.So no win for black.It is advantage white.
See how bad 23.Qxg7? is after f3!.But all this is history.Computers are getting
stronger and stronger.Any other programs are playing 23.Nxf4!! ?
