I am playing against this really loose guy, playing something like 60/20, but fairly OK postflop, and relatively aggressive. He has also been drawing out/getting lucky a lot and has a huge stack. I have caught him bluffing before. Example:
He raises to 7, I call with JTs in the BB (and one more call), flop is 69T with ad FD. I check call a 15 bet, other guy is out. Turn is a Q making it a double FD. Check/Check. River is a 4 not making the flush. I lead 1/3 of the pot, he raises to 3 times my bet. I think and call. He had 77. Maybe not that well played by me, but still.

To the hand:

I have 475 UTG and limp with , CO rasies to 8, villain calls in the SB with a 655 stack. I raise to 28, only villain calls. ( I know that the limp/raise is questionable, but very aggressive table...)

Flop:[4s] (pot 62)
Villain check calls my 46 bet

Turn (pot 154)
Villaind check calls my 132 bet

River (pot 418)
Villain puts me all in for my remaining 270ish. I am getting 2.5:1 I think.

Comments all all streets are welcome.

I think I have to call against this guy. If he caught the flush, its his lucky day.

His range is pretty wide here I think.

I call. If he caught his flush you bet enough on the turn that you don't really lose any sklansky bucks here anyway. He's bluffing here a lot too.

i think you have to call here.

even if you pay him off every time he has a flush....it is -EV (albeit not hugely so) for him to chase his 7 outs (assuming he gets himself stacked when the river is the ).

add in the times he has a set, 2 pair, bluf/whatever, and this is a must-call.

Thanks for your input.

To my defence on the flop, I rarely limp-reraise at all 5 handed, but every time I had limped this guy had raised me (even OOP), so I was hoping for a situation where he would do it again and I could just call him down. But I didn't want to be three people in the hand, hence the limp-reraise. Which was too small.

I almost timed out before calling.
He had (so he actually had the full 8 outs)

I just wanted to check if you guys would find a fold there. And now I have to go out and see what I can buy for my Sklansky dollars...

FWIW, unless it's against a competent opponent, they're still willin to pay off the limp rr with TP+.
