Again this will be a matter of taste. In my opinion the gxh7 is the
more conservative, less forcing line. The pawn on the 7th is serving
as a shield to the black king. This position will be interesting
as other programs submit analyse. I agree that both moves gxh7 and Qxd6
would cause a swift resignation in a GM game.
