This situation just came up and after discussing it with a few friends who had different opinions I want to see what everyone else thinks.

1/2NL

Story behind villain. He lost a massive pot about 4 hands prior to being heads up with me. The situation was he had K6off on a 652 board. He raised preflop with a stack around $350 UTG+2 to $14. 7 player table everyone calls. Flop comes 652 rainbow. He bets flop around $30 3 people call. Turn is a 10 he fires again about $125 one player calls. River is an queen. He jams one player called and the other player had a set of 2's. So he immediately rebuys. The next 3 hands were pots raised preflop and he was involved in all of them. None of it was high betting and or went all the way to show down so no clue what he had. From my time at the table I already realized he was a LAG player.

Now my hand. I have AK of hearts. I raise from the CO to $12 the villain in the BTN calls so do 2 other players. Flop comes 445 villain leads out for the pot. I end up calling I just knew he was bluffing and trying to take down a pot, his heart was beating fairly hard which it had been from previous hands he lost which made me think he was bluffing. I also knew he was a LAG and didn't think the board hit whatever he called my raise with preflop in anyway. Turn was a $10 he bets $70 I call river is a 7 I checked he checked and he had K10 off.

Question is do you flat on the flop, raise the flop or just fold. I had about $290 at the time he had roughly the same I want to say around $250

My suggestion is being patient against maniacs and try to have a solid strong flopped hand and sooner or later he’s gonna fire right into you. Don't just go after him because you think he's bluffing. You know, maniacs are entitle to good hands too, you know. If he’s raising six hands out of ten. It doesn’t mean one or two out of his six raising hands he may not have some value. Since you have position, you just call and let him fire into you three streets and just play position on him and make decision on each street like flop, turn and river. Don’t force yourself to play hands just because you want to isolate the maniac.

Unless your some sort of jedi mind trick master how exactly are you determining that his heart is beating fast
....
Also the guy just bluff shoved for a full stack 4 hands ago, I seriously doubt this $30 flop bet is really bothering him......

How is villan leading at the pot when he calls from the btn pre-flop,
Your oop here and without making a hand are going to struggle here. Yes your probably ahead but your going to face three streets, and I'm not calling down with a high no matter how spewy my villan is....

OP, Don't post results as it skews replies.

There's $48 - $5 rake = $43 going into the Flop & he bet $40-$45?
If you really believe he's bluffing - x/r after the other 2 fold. If you do & you're right, he folds. Unless he has AK, AQs, maybe AJs & then you're screwed being OOP.
However, if he folds hands like KTo, QJo etc. to your x/r of the pot, then you take it down otf.

Your V caught a mudda' fuddin' 3 outta' on the Turn! You had him by the ballz! Well, OTF you did.

What sux is that he calls with PPs, so you lose OTT when you give up.

If you can't play this guy OOP, which I would not want to do, I would table change if I can't get a seat change.
