I am not sure.
I suspect that if you let it to search for many hours it may see that every move
is losing a pawn and may prefer 34...Rd8
I try to go backward with yace(only material) to find when black lost a pawn and
I got into move 38 when yace(only material) suggest 38...h6 with 0.00 evaluation
but yace(no material) used only few minutes so maybe at depth>18 it can find
positive score for white.
I do not know if 38...h6 was better but there are positional reasons to prefer
38...h6
After 38...h6 only g7 is not protected(from h6,g7,f6,e5) when after 38...g6 both
h7 and f6 are not protected so at least for me 38...h6 seems to be better.
