I think this is a fairly interesting spot on the river where I'm not sure if I made the right play. This is the original raiser's second hand at the table so no reads or stats. Villain who flat calls my 3-bet is 24/10 over 21 hands, so pretty small sample. I decided to 3-bet as I didn't want loads of people coming in behind if I just flat, and I feel JJ is good enough to 3bet here, even though I know nothing about the original raiser's range. Do you think 3-betting here is fine? I think my post-flop play is OK, although maybe I could bet a little more on the flop and turn. On the river I decided that he would check behind everything that I beat and bet anything that I lose to so a check/fold was fine – what do you guys think? The only bluff I beat here is 76 and I really feel that JJ is just a bluff-catcher at this point.
