Short diagonal position

Hi everyone,

do you think this position is already winning for black?

If not, what is the correct response for white? Maybe even not correct, but something like "still-living" move?

I think it's hopeless for white.

Maybe there is a trick to stay alive and force an error but I cannot see any and wouldn't like to look for that in a game :)

At first look, 8 h3 maybe?
