Big draw heads up (live 10/20)

[Proofrock]

Live 10/20 game with a half kill. I won the last pot and post the $15 kill UTG+1 (in this game kill acts last preflop). Folds to MP TAG who raises, I defend with A[img]/images/graemlins/diamond.gif[/img] 6[img]/images/graemlins/diamond.gif[/img]. My image is TAG.

Flop (5 SB): 7[img]/images/graemlins/diamond.gif[/img] 8[img]/images/graemlins/diamond.gif[/img] 9[img]/images/graemlins/spade.gif[/img]
I check, Villain bets, I raise, Villain 3-bets, I 4-bet, Villain calls.

Turn (6.5BB): 3[img]/images/graemlins/heart.gif[/img]
I bet, Villain insta-calls.

River (8.5BB): 2[img]/images/graemlins/heart.gif[/img]
I start counting out chips, Villain beats me into the pot with his call, so I check, he says, "okay, then I bet," I fold.


Comments on flop and turn?

Is a river check raise here sexy or spewy?
