First, thanks to everyone for the feedback. I've been playing around with this quite a bit, and if 33 is ...Qe7, I'm finding a lot of 'draw' endgames.
But it seems like 33. ...Qf8 deserves a (!!). Black wins every time I play a different (decent) variation, and I can't seem to figure out what's so great about black position following the queen exchange. I haven't even found a good response for 34 to answer Qf8 (though I haven't played many variations that avoid the exchange).
Aaron: what are white's "big mistakes"?Muro: your variation still leads to a black win.
