I check/call that river often to induce a bluff from a busted draw, if he had a set you would expect a raise on the turn.

Yes, AQ,QT,22,44 would have made themselves known by now (hopfully). Looks like a busted FD. You have to check-call there as u cant bet it. I dont think QJ,JJ,AT is gonna call all 3 streets.

I sweated about it for 10 seconds and finally called. He had [Jc] for the busted straight and flush draws.
