I probably play it the same, but his river check beffudles me.

I'm consider rasing thei turn but without reads I probably don't.

Was it TT or something?

I think your line looks good here, not too many other ways to play it though. I don't think a raise anywhere will do much for you other than cost you more bets when he has an overpair as you'll never be folding a hand that you beat.

It looks like he has an overpair like Kings or Queens, are you paying off a river bet here?

I think you can probably fold this river if he bets, kinda hard to see him capping pre-flop without having you beat here, unless he's been known to cap KQ, KJ and etc. The other option would be to try a check/raise against someone who likes to value bet and would fold a hand like Kings or Queens after that Ace hits the river, but again you'd need a real good read to try that.

I mightve checkraised turn. Its fairly safe, and if 3 bet fold.

i know it doesn't matter all that much, but i'm curious why you went with the l/r/r preflop. just out of whimsy?

Would be awful. We are open ended on the turn and the pot would be big.
