you had a mate in 1 with rg3 on move 28
28.Rg3 Rxe5 wasn't mate. But White did have a mating attack. one line: 28.Re7+ Kg8 29.Bh7+ Nxh7 30.Qg6+ K moves 31.Qg7#
Instead he decided to win the Q which ended up with a faster win by resignation!
Actually, that 30 Qg6 is #. And there were two other fairly cute mate in 3's he missed:
27 Bh7+ Nxh7 28 Rxg7+ and...
28 Rg8+ Kxg8 29 Bh7+
(And for that matter, 28 Be6 looks pretty much unanswerable.)
Hard for there not to be a fistful of wins when you have that much lumber aiming at the king.
