Questionable cbet and now I'm confused.....

[HoldEmNewby]

Villain is pretty decent 20/18/2, Sb was a tightish player

SB ($180.60)
BB ($100)
UTG ($160.02)
Hero ($96.85)
CO ($50)
Button ($108.69)

Preflop: Hero is MP with A[img]/images/graemlins/spade.gif[/img], 6[img]/images/graemlins/spade.gif[/img]. SB posts a blind of $0.5.
UTG calls $1, <font color="#CC3333">Hero raises to $5</font>, <font color="#666666">1 fold</font>, Button calls $5, SB (poster) calls $4.5, <font color="#666666">1 fold</font>, UTG folds.

Flop: ($17) 2[img]/images/graemlins/spade.gif[/img], 6[img]/images/graemlins/heart.gif[/img], J[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(3 players)</font>
SB checks, <font color="#CC3333">Hero bets $10</font>, Button calls $10, SB folds.

Turn: ($27) 4[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(2 players)</font>

Whats my line on the turn? and how do you play a river A[img]/images/graemlins/club.gif[/img] with your line?

While we're at it if any one wants to suggest alternate flop lines I'm all ears as well.
