Representing a bluff with an overbet.

[DoomSlice]

Villain in this hand is 36/4/0

I've been playing very aggressively both pre and post-flop, and I'm positive that Villain has noticed. The plan here was to check the turn/river unimproved.

PP NL 25 6-max

Hero is Button ($53) with KT [img]/images/graemlins/spade.gif[/img]
Villain is SB ($22)

Preflop:
folds to Hero, Hero raises to $1, SB calls .90, BB folds

Flop ($2.25):
6 [img]/images/graemlins/spade.gif[/img] 6 [img]/images/graemlins/diamond.gif[/img] T [img]/images/graemlins/club.gif[/img]
SB checks, Hero bets $1.75, SB calls $1.75

Turn ($6) : T [img]/images/graemlins/heart.gif[/img]
SB checks, Hero bets $8

I thought that betting any less would look like a value bet. I'm putting SB on a pair bigger than a 6 at this point.

Who likes/dislikes, and what are other alternatives.
