2-4 Heads up. TP problems

[ahnuld]

500 stacks each. He min raises 75% of his hands from the sb (button) and folds the other quarter. He mixes it up nicely, and is tricky enough. I caught him bluffing air before on a 4 straight board when I had aces and didnt buy it. I get AQ and he min raises. I only call for some stupid reason (oh yeah, I was trying to trap him, wtf is wrong with me sometimes)

Flop comes Q [img]/images/graemlins/spade.gif[/img] 6 [img]/images/graemlins/diamond.gif[/img] 8 [img]/images/graemlins/spade.gif[/img]. I check, he bets 12, I make it 36, he calls. Put him on some Q or maybe a flush draw or maybe a delayed bluff (not often though). Turn is J [img]/images/graemlins/club.gif[/img] I bet for 68 into 88. He calls. River is K [img]/images/graemlins/spade.gif[/img]. Yuck. Line? If check call, up to how much?
