ok so villian is a regular i play with, playing 14 11 4 over 11k hands. he is pretty competent and doesn't get out of line that often.

Pre is close between a 3bet and a flat but the sb is a total fish so i decide to flat to hopefully get him in too, plus my hand plays well in position

obv a good flop

I think a raise is pretty standard here. I want to build a pot for times I hit, plus I get value from any weaker flush draws.

When he flats i'm ruling out JJ 77 and 33 as I think this player would 3bet the flop with those hands.

He prob has AA-QQ, AJ KJ QJ maybe, or like 98 clubs, 67 clubs maybe

I genuinely do not know whether to bet or check back here.

I very likely have the best hand, but I don't want to be raised off a re-draw if i'm behind?

I now beat KK plus all his Jacks except AJ, so value is best?

He tanked then called.

he just ships it on the river. WTF?

I'm in the tank for ages. A lot of other players I would call here, his line doesn't make a lot of sense unless he has specifically AA for value? although wouldn't that x/ship the turn?

Other than that it's some kind of missed draw right?

I just can't see him shipping like 89 clubs here, it just looks so much like a bluff and he knows that....

I fold. My hand is essentially a bluff catcher.

pffffffft. what do we think?
