pf decision w/AQos 4bet this? -- 50NL

[Kasane]

Table was more or less unknown except that it was 50+vpip when I joined a couple rounds ago. Real loosy-goosy from what I'd observed so far.

Full Tilt No-Limit Hold'em, $0.50 BB (6 handed) Full Tilt Converter Tool from FlopTurnRiver.com (Format: 2+2 Forums)

Hero ($50)
MP ($30.50)
CO ($3.60)
Button ($59.70)
SB ($63.20)
BB ($92.95)

Preflop: Hero is UTG with A[img]/images/graemlins/heart.gif[/img], Q[img]/images/graemlins/spade.gif[/img].
<font color="#CC3333">Hero raises to $2</font>, <font color="#666666">1 fold</font>, <font color="#CC3333">CO raises to $3.5</font>, Button calls $3.50, SB calls $3.25, BB calls $3, <font color="#CC3333">Hero raises to $23</font>?...

Frankly, I didn't expect the betting to be reopened here, but I kinda forgot that when I bet $2 on the first go around that it was a raise of $1.5. It was important because, if I remember right, shorty had just lost his stack and they go all in on such a wide range here that I was truly expecting it. Then I thought that I probably like the fact that I would still like to be able to 4bet.

I almost never 4bet AQos, but this felt right...
