QQ turn decision

[TJD]

I am still new to $15/$30 and am trying to get a sense of the way the game plays.

I have Q [img]/images/graemlins/heart.gif[/img]Q [img]/images/graemlins/club.gif[/img] in MP.

UTG+1 limps, I raise. CO and both blinds call as does limper.

Flop is A [img]/images/graemlins/spade.gif[/img]8 [img]/images/graemlins/club.gif[/img]6 [img]/images/graemlins/club.gif[/img] (5 players, 10SB)

3 checks to me and I bet. Just CO and BB call

Turn is 10 [img]/images/graemlins/diamond.gif[/img] (3 players, 6.5BB)

BB checks - me?

BB is 13/6 medium aggression with a bit of larceny in him
CO is 25/14 with medium aggression as well but too few hands to know much else.

Is a bet automatic here? With so many callers of my PFR and 2 callers on an A high flop - do I need to take the foot off or keep pounding.

If I bet and am raised, I......?
If I check, CO bets and BB folds. I .......?
If I check, CO bets and BB calls, I .......?

Thanks all
