400 NL TPTK facing river raise

[mikeyworm]

This is on Stars but I don't have the HH with me. Villain in this hand seems like a decent LAG. We had been playing for about 50 hands and he had been raising turn bets pretty frequently. The hand immediatley before this was:

I raised A9o CO ro 16 and only villain called from the BTN.

Flop was T [img]/images/graemlins/diamond.gif[/img] 5 [img]/images/graemlins/spade.gif[/img] 2 [img]/images/graemlins/diamond.gif[/img] and villain called my C-bet of 28. Turn was the A [img]/images/graemlins/diamond.gif[/img] ( I have no diamond) and I checked. Villain bet 52 and I raised to 162. He thought for a while, typed in "flush?" and then folded.

The very next hand (and the one in question) I have A [img]/images/graemlins/diamond.gif[/img] K [img]/images/graemlins/diamond.gif[/img] and raise to 16 from UTG. Villain is the only caller in the CO. The flop is A [img]/images/graemlins/club.gif[/img] 7 [img]/images/graemlins/spade.gif[/img] 6 [img]/images/graemlins/heart.gif[/img]. I bet 33 and villain quickly calls. Turn is the 7 [img]/images/graemlins/club.gif[/img]. I check and villain checks. (what do we think of the turn check?) River is the 2 [img]/images/graemlins/diamond.gif[/img]. I bet 68 into a pot of 104 and he raises me to 200 flat. What do I do here?

Thanks.
