Very difficult indeed, Yace and Chezzz like 1...hxg4 and could not see 1...h4!!
if then 2. g3 h3!, could this be a good test for pin and king mobility perhaps.
Black has to see that a pawn on h3 is paralyzing for white.
Kasparov in one of his own game analysis told that a pawn on h3 by black with
white on g3/h2 is generally advantageous.
