I analyzed 38...h6 and got the impression that it is losing.
A possible line is 38...h6 39.g4 Qg6 40.Rf8 Nxf8 41.Rxf8 Qg6 42.Rg8 Kc8 43.g5

Maybe 39...Qg6 is not the best and after going back with yace it prefers
39...Qe8 with only +1.19 for white but I do not believe in that move
and yace fails low at depth 16 when the only third alternative Qh4 failed low at
depth 15.
