How's my line here?

[JCCARL]

Preflop: Hero is BB with 7[img]/images/graemlins/spade.gif[/img], 6[img]/images/graemlins/spade.gif[/img].
4 folds[/i]</font>, CO calls, 1 fold[/i]</font>, SB completes, Hero checks.

Flop: (3 SB) 4[img]/images/graemlins/heart.gif[/img], A[img]/images/graemlins/spade.gif[/img], 8[img]/images/graemlins/spade.gif[/img] (3 players)</font>
SB checks, Hero bets</font>, CO calls, SB folds.

With 12 outs on this board my hand some value. I thought CO would have raise pre-flop with any ace. I also thought there was a chance I might pick up the pot right away.


Turn: (2.50 BB) J[img]/images/graemlins/heart.gif[/img] (2 players)</font>
Hero bets</font>, CO raises</font>, Hero calls.
I fired another barrel on the turn for pretty much the same reason as the flop bet. Should I have simply check called the turn?

River: (6.50 BB) 4[img]/images/graemlins/diamond.gif[/img] (2 players)</font>
Hero checks, CO bets</font>, Hero folds.

Final Pot: 7.50 BB

Comments on all streets welcome.
