I fold to his c/raise flop... Like you said, his hand is face up. He's just showing too much strength. He limp raised, now c/raise - he's strong as hell and you didn't give any details on his tendencies, but I'm not gonna float this trying to hit my 6 clean outs. I'm also not gonna float this hoping to hit a heart and try to make him fold sets because he's a fish and fish don't fold sets (this is a general assumption and obv not always true, but without anything else to go on I think its a good assumption.)   

I don't think you are deep enough to play this hand this way with this fish in this inflated 3bet pot. I think if you were both like 5k deep or something, you could MAYBE try your line because you'd have higher implied odds to make your hand and also you'd have the ability to apply more pressure to the fish if the heart comes ... But with stacks as is, I don't like your line here ...

fold pre, enough with the fancy play syndrome. you just get buried every time

limp pre ainec

you're folding a suited connector vs a face up range 260bb deep?  Preflop play is absolutely fine IMO

I'd probably check back flop and go from there.. I'd also check back some Kx i may have called..  I don't think he's ever checking that flop to fold so you have little fold equiity.  If you're trying to make him fold under pairs that can be accomplished on later streets..  I suppose that betting is ok too but when he xr you, River jam is terrible don't think he's folding top two or a set there... He pretty much announced his hand to you and you still jam.. Why not hit and stack him instead of punting your stack away? 

The guys who limps never make huge laydowns. Never expect it. Play as exploitive as possible when you have made hands and stay up against them. 

i would play the same, but i give up river

If he has the Ah in his hand, you have very few flushes in your range.

Preflop is loose, but if you're deep against weak competition, why not. However the preflop call becomes very bad if you makes big mistakes postflop (as you make here). You have to ask yourself what you think vilain's range is, when he limps / RR UTG. I think you didn't ask yourself this question, otherwise you would just have checked back flop (I find the flop bet very bad, you should always take a free card IMO). As played, ok call flop, call turn, but already it's not such a favorable situation even, although you're given a good price.

River is almost always a give up, you say yourself that vilain is faced up as having top or second set. Do players ever fold set in huge, bloated reraised pot? I doubt so very much, especially from a player that chooses to limp/RR, therefore likely not so good in the first place.

And as I said, it's not because the river brings the flush that you can effectively rep it. You can have the nut heart FD, QhJh, JhTh, Th8h. Is the Kh on board? That also is important. Anyway, if vilain has the Ah, he has a pretty easy call, as you rep 3/4 combos of flush and, anyway, people don't fold strong hands, so doesn't matter if you can have enough flush as compared to bluffs.

You played it ok just give up on the river. 

You said his range is very face up as top set on flop yet you still try to bluff him off of it on the river?

i don't see a point in having a much of a flop betting range when he's polarized to AK+ (really don't think he limp RR's QQ pre).  

also i disagree with the advice to fold pre to the raise at this depth in a live game.

i'd probably be more inclined to raise the weaker villain's game is

Isolating can get out of hand when players limping a stronger range but IP deep-stacked its fine. I see plenty of limps with hands like AQ BWs and so the value of isolating offsuit BW and SCS 1g 2g goes down, the deception and position does work in your favour.

Your flop bet is mindless, villain limp-raises preflop and checks a King high flop, from experience that is AK/KK all day. Take the free card and see what develops.

His hand is face up here as kings.

He eventually calls with set of aces.

It's not really isolating when there's already two limpers. Just limp behind and see a cheap flop IP instead of re-opening the action. 

by the way why do we even bet the flop?
