Party 2/4 AQo MP1

[coolhanded]

No real read on villain---he was new to table.

Hero is MP1 with A [img]/images/graemlins/club.gif[/img]Q [img]/images/graemlins/diamond.gif[/img]

3 folds, Hero raises, 2 folds, CO calls, button folds, SB folds, BB calls.

Flop A [img]/images/graemlins/heart.gif[/img]9 [img]/images/graemlins/heart.gif[/img]2 [img]/images/graemlins/heart.gif[/img]

BB checks, Hero bets, CO raises, BB folds, Hero calls

Turn 5 [img]/images/graemlins/club.gif[/img]

Hero checks, CO bets...

What now? And should I have folded the flop after the raise?
