A hand

[Clarkmeister]

Live game. Villan is loosish and more aggressive than most but plays reasonably well overall. We've played together enough to be familiar with each other, he likely thinks I'm somewhat tight/predictable - at least relative to himself.

I open raise in MP with ThTc. He 3-bets out of the BB. I 4-bet (pretty standard against his range here if that gives you an idea), he calls.

Flop is Ah 9h 3c. He checks, I bet, he calls.

Turn is 8s. He pauses, ponders and bets. I raise, he calls.

River is 6c. He pauses again, bets again. I call.

Thoughts?
