I'm proably just calling here, I would only rr the river if I was willing to get it allin if he came over the top, which with that board, I wouldn't be. To be honest i'd think with the size of his bet he's proably just making a small stab at the pot, a bet to try to stop you betting more and try to see a showdown cheap,  just making a little value of his 33 or badly played A3(doubtfull), or a made flush which hes hoping for a rr.

 I would by the way it was played tho proably put the Co on a flush draw as I cant think of many other hands he would  call the flop and fold the turn when the price is a little higher, except maybe AJ, KJ or QJ, but with these hands I would have expected a rr from the Co on the flop.

I'd definately just call, unless i'd seen this small bet from him before and I thought he was just trying to get a cheap showdown with top or 2nd pair.

yeah, I just called, he showed J4o so I defo lost some value… I didn't want to rr for the points Third@eye pointed out. If he puts me to the test I really don't want to call him.

be sad that river isn't a blank. Be happy that he bets almost min and just snap it 🙂 In most cases I think he will turn up here with a weak J or 2 pair  though, sometimes a str8 or really weak flush. But my experience is that he will turn up with a weak J or 2p most of the times.

I also just flat with such a wet board would obv hate it if he shoved over my value raise for that reason i always flat in these sigh spots…..which means i probably miss value sometimes.
