15/30 weak ace vs. 3 bettor

[geormiet]

8 handed online game. Cutoff is slightly overaggressive preflop, but is a smart player postflop.

I raise in late middle with A [img]/images/graemlins/heart.gif[/img]3 [img]/images/graemlins/heart.gif[/img], i'm 3 bet by the cutoff, folded to me, I call.

Flop is T [img]/images/graemlins/heart.gif[/img]9 [img]/images/graemlins/heart.gif[/img]6 [img]/images/graemlins/club.gif[/img].

I check call the flop.

the turn blanks, I check intending to call, he checks.

the river blanks, i check without really having an intention except maybe folding, he checks.


Am i gaining or losing by not making some sort of semibluff raise at some point in this hand? I feel like c-r the flop is standard, but it feels to me like I'm getting called down by the vast majority of his 3 betting hands.
