Bet more on the flop, something like 6 or 7. As played, call the raise.
On the turn villain most likely isn't checking two pair or a set, when there is a fd present.
On the river you make a very weak bet. Villain has a veryhigh aggr. factor so he probably could be shoving a missed draw, trying to make you fold some weak one pair hand. He could even be value shoving KQ.
Im not folding on the river, especially as we are getting good odds:

(28+40+9)/31=2.5

I'm not fond of your bet sizing here. This is a good flop for you, you should bet at least 6-7 for value, to charge flush draws, and also to discourage CO from bluff-raising, since with his AF he is probably bluff-raising c-bets on this board at least a fair amount of the time.

After CO checks the turn, I think your hand is almost always best, but again you make a very weak-looking bet and I think he can easily be raising with a busted draw or lower pocket pairs. You are getting about 2.5:1 which I think makes this a clear call. The only hands he has here which you are behind are sets, and as weak as your line looks he is betting a lot more than sets here in my opinion.

So bet more on the flop. If he still makes a big raise, then you have a tough decision, but by playing so weak you make it easy for him to run over you.

I dont get your river bet. c/c this river. As played I fold but seriously, I dont get the river bet, its too small for a blocking bet.

His solid stats lead me to believe he is raising the flop b/c he thinks you have nothing or he is wanting a free card with his FD.

I probably call because a) his line looks like garbage and b) your river bet is terrible and begging to be raised

[Unknown Soldier]

c/c river, his betting range &gt; calling range after the flop/turn action. As played i look him up, his line makes absolutely no sense.
