Bet this river or check it? If bet, how much?

[7n7]

Villain is 27/6 over 200 hands, so not much info. He had a large stack much of the time I was at the table but didn't get out of line that much.

Why are you c/r this turn?

[SouthernGrown]

why would you check the river with a flush there??? No offense but why are you playing .50/1 if you are doing such things???

I think as played it seems like he's on either a flushdraw or a hand like 9x, 5x, and I think that betting the river OOP folds out basically all of those hands, so even though I don't feel like he'll be bluffing this river you should check to induce and call. There is the chance that you're outkicked here but hes probably going to check down most kings as well.

Why are you checking the turn here? I like to bet/fold turn, or bet turn then c/c a non club river.

I had c/r'd 3 or 4 times this session and always showed a monster when I did it (had to show twice). He seemed to be the only thinking player at the table. Bad move?

I also thought he was capable of betting small on the turn to see a flush draw cheap. So, I raised him. When he just called, I changed my read to K, weak kicker, but probably a bit stronger than mine.

Afraid I don't understand this reply. What flush?
