Not sure if I should bet the flop and if I should call the river. Any thoughts would be appreciated.

Hand too good to fold to one bet imo but he probably had it.

I think you just have to call here. Any reads on villain? If he is a reg this is very likely a bluff (87 or 89 clubs really the only two value hands he can have here), if he's a fish he might have it. Either way im calling, wouldn't be surprised to see a fish betting a king on the river here as well.

Flop, turn is fine and river we have to call single bet otr when we are getting 1.5 - 1 pot odds.. we only need to show the best hand 40% of the time or so to breakeven

Its just I don't really think he would bluff on this board against a player who 3 bet pre. I guess maybe I could bet the turn so that he doesn't try to bluff the river?

I feel like if Hero doesn't bet flop and turn, he won't have the flush draw. I'm saying this because the flop hits hard on the range of Hero (because of 3-bet pre) and if he had the draw he for sure bets one of the streets for value.

So I think that Villain could in fact bluff the river, if he thinks that Hero could fold a straight.

Is villain value betting 2 pairs on this board? I don't think so.
So I think he can be bluffing or he has the flush, since we are blocking K.

As played, I think we have to fold river.
But since we have position, I would bet turn because Villain has checked two streets and our hand has good value. I would bet a little big because of all the draws, like 500. I would fold to river bet if called on turn.

I'm a noob so, I most certainly am wrong.
