I've been playing against sb for about an hour, he seems to be getting laggy.

Bet/fold the river. How often he was bluffing the turn and wont call a river bet here is irrelevent, because in these scenarios it does not matter what you do. He will have an ace he calls with or a low pair more often then he checkraises here. I think he check/calls with almost nothing you lose to.

Edit: I want a read better then "seems to be getting laggy". To me this means he is mostly tag, but I am not sure at all.

The prospect of getting checkraised on the river and having to call him down because he's a lag kinda sucks. Also, if he's checkraising you on the turn on a bluff, he's most likely not calling a river bet.

You're right, he check calls with nothing I lose to.

Hard to make those thin value bets when five tabling, guess I was already in the check/call any box before thinking.

I checked and he showed ace deuce of hearts.
