How do you devalue outs?

[SenecaJim]

In a live game a new player had been in the game about half hour ( no read yet, seemed a little loose in general). It was his 2nd raise in game and from the MP3 position. Button called, I rerasied with AKo in SB, MP1 limer called ,Raiser called, Button capped, all call.

Flop is 5 [img]/images/graemlins/heart.gif[/img] 8 : [img]/images/graemlins/club.gif[/img]Q [img]/images/graemlins/diamond.gif[/img]
I check, Initial raiser bets, button and I call, limper folds.
Turn is Q [img]/images/graemlins/heart.gif[/img] I check, raiser bets, button calls, I ?

Ok , I know pot is big. But trying to evaluate with calculations here. Pot is 11.5 bb's. More than enough for six outs, but if the A and K are 1/2 out each, not enough for a call.

Not much of a read on new guy, so calling reraise makes AQ even more likely or KQ or weak ace? I figure button for pocket pair which he had. So I beat a weak ace but makes one less available. Anyway, can someone give me an organized approach in this situation that one should employ?
