Villain was on the loose side. I probably should have raised the turn but I've been working on my small ball approach and probably play too small sometimes. But now what do I do facing that river bet?

I would have raised the turn but as played, I fold. He could have bet the turn with gutters or something like J10. He limped preflop also so it might even be a horridly played AK/AA etc.

Guy prolly has a ragedy A.

Fold

Gah that's a pretty strong bet from UTG, given that two people called him on the turn it's probably rarer that he's outright bluffing, and you don't really beat anything he's value betting for that much, so I think this is a reluctant fold.

I think you played the rest of the hand well too.

what?
