($16) AQ - facing flop 3-bet

[11t]

No reads (as per standard at this stage). Converter seems to be malfunctioning. All comments appreciated.

Hand 1:

Blinds are 15/30

Relevant stacks (9 handed):

MP2 (1380)
Hero in CO (1820)

Folds to MP who raises 3xbb, Hero calls with A [img]/images/graemlins/spade.gif[/img]Q [img]/images/graemlins/heart.gif[/img]

flop is Q[img]/images/graemlins/spade.gif[/img] T[img]/images/graemlins/spade.gif[/img] 6[img]/images/graemlins/heart.gif[/img] pot is (225)

MP bets 120, Hero raises 180 to 300, MP raises 360 to 660, Hero...

So in a ring game versus a non super LAG I would muck this instantly but I wanted to pursue it further for some reason in a tournament setting. Standard fold?
