Turn Semi-Bluff at the Stone

[W. Deranged]

5/10 at Turning Stone. Table is looser than Stone 5/10 often is (pretty standard by small stakes standards). A couple of players in the game are pretty bad/Laggy and are willing to put in pre-flop raises with hands like A4.

The player in question in seat 6 and is UTG +2. He's a regular, calling station who will call the flop turn with a lot of hands he should fold and a lot of hands he should raise.

Hero is on the button with K [img]/images/graemlins/heart.gif[/img] 8 [img]/images/graemlins/heart.gif[/img].

Pre-flop: 3 limps to Hero, who calls (is this way too loose???). Blinds both play.

Flop: J 7 3, one heart. (6 players).

All players check.

Turn: J [img]/images/graemlins/heart.gif[/img]

5 check to Hero, who bets. Seat 6 calls and all else fold.

River: 4 [img]/images/graemlins/heart.gif[/img]

Seat 6 bets, Hero raises, Seat 6 three-bets, Hero calls.

Final pot: 11 BB between seat 6 and Hero.

Am I getting way out of hand here?
