River Call W/ Ace High?

[Knockwurst]

Local B&M 10/20--half kill. Usual assortment of LAGS, TAGS and HAGS. I raise UTG with A [img]/images/graemlins/diamond.gif[/img] Q [img]/images/graemlins/heart.gif[/img]; TAGGY-LAGGY Button, who's posted a kill, calls and BB completes. 3 players -- 6 1/2 small bets.

Flop is J [img]/images/graemlins/diamond.gif[/img] 6 [img]/images/graemlins/diamond.gif[/img] 4 [img]/images/graemlins/diamond.gif[/img]

I bet, button raises, BB folds, I call (?!?). (Maybe I should have raised here). 2 players -- 10 1/2 small bets.

Turn is 9 [img]/images/graemlins/club.gif[/img]

I check, button bets, I call (?!?). (Maybe I should have gone for a semi-bluff checkraise with the idea of betting out on the end if he just calls). 2 players -- approx. 7 beg bets.

I check, button bets ....

What's the correct play here? Call, raise or fold? Also any suggestions for other streets? I think I probably should have put in a reraise on the flop or check raise on the turn or maybe even one on the river.

Any suggestions appreciated.
