Blunderthon Continues

HAD a lucky escape today after pushing too hard in a drawn position.

Position after 32.Bb4-d6 in Jiri Fiala (1849) - Spanton (1946), Olomouc Seniors round seven

I had already rejected two draw offers, and now made matters worse by playing 32...Nh5? without noticing White could reply 33.g4
Luckily for me, I had 33...Qg6 (not 33...Qf6?? 34.Be5)
JF played 34.Be5 anyway, and now 34...Ng7 would have given some drawing chances, although White is much better, eg 35.Qh4 Qf7 36.Bf4 h5! (not 36...Qg6 37.Qe7) 37.Kg3, which looks pretty grim for Black.
Instead I played 34...Nf6? and, luckily for me, my opponent was so intent on drawing that he played 35.Bxf6? and the game was indeed drawn a few moves later.
He should have played 35.Qh4, eg 35...Kg7 36.Qxf6+ (even better is 36.b4, according to Komodo9 and Stockfish9) Qxf6 37.Bxf6+ Kxf6, with a fairly straightforward pawn-ending win for White.
