"TPTK" with a couple maniacs

[yellovizion]

OK - Game is 3/6 live. Shorthanded. SB is loose passive, BB is too, UTG is a calling station (within the last few hands he has begun calling anything down to the river blind, and then he jumps up to flip his cards over at showdown to see if he won) I'm UTG, BTN is a calling station (he's also calling blind, but he's also doing a bit of blind raising). This game is sick - I'm having a blast and getting the monies. They have all noticed I am playing tight.

UTG calls blind, I call with A7o (no hearts), BTN raises blind, SB, BB and everyone else calls.

Flop is 2 4 7 with two hearts. SB checks, BB bets, UTG looks at his cards (wtf?!) and folds, I raise, BTN looks at his cards (wtf?!), and calls, SB thinks for a while, then says he thinks I have a set, and folds, BB calls.

Turn is a black K.

BB checks, I insta-bet, BTN calls and says he'll call me down to the river, BB folds.

River is the 8 of diamonds.

I...

Also, feel free to rate my pf, f, and turn lines.

Cheers
