villain is 25/13 over about a hundred hands nothing id found interesting bout his play. this is his first flop chk raise
i think my flop bet is too big and i think calling his raise is prolly not that good either ive got about 30% vs 2 pair sets straights and overpairs which is prolly optimistic.
can we v bet the river assuming 2nl villains are gonna be stationary with AA KK 2 pairs and sets and is super unlikely to ever have a straight here given his line.

Check flop - you're not really getting called by much worse, getting raised (substantially) is horrible for you and yeah you have sd value and equity you don't want to get blown off of. As played I'd give him a range of sets and some overpairs on the flop. By the river we can probably remove QQ (or any other random Qx) from this and expect to be good a lot. I'd bet small for value vs the rest of his range. 60c should do the trick, just pick a size he can call with [99 88 KK AA]

Agree completely with the carrot man. As played though, calling flop c/min raise seems mandatory given odds and I think your range assessment is bang on for a typical 2nl player that takes this line.
