Ok, some self-analysis after aim'ing with Halv about it...

Pre-flop & Flop: Good.

Turn: Bad. I was trying to rep a full house, get a free card, and win a huge pot if we both hit flushes. WTF. Why rep the least likely hand when I can rep an 8 and probably get him to fold his most likely hands (TT-99) while I still have decent equity in case he calls? I should have pushed here.

River: Bad if he's even remotely capable of hand reading. I don't have an 8, so he has to put me on quads or 22. If he folds it's either because I have the best hand or he's a ridiculously bad nit.
