How hard did he hit? AQs

[StellarWind]

5-handed. Hero is Button with A [img]/images/graemlins/heart.gif[/img] Q [img]/images/graemlins/heart.gif[/img].

Limp, limp, I raise, BB calls and the limpers call. Four to the flop for 8.5 SB.

Flop is A [img]/images/graemlins/spade.gif[/img] 5 [img]/images/graemlins/heart.gif[/img] 2 [img]/images/graemlins/club.gif[/img]. I bet and all call. Four to the turn for 6.25 BB.

Turn is Q [img]/images/graemlins/club.gif[/img]. Only Cutoff calls this time. Cutoff is 36/7 preflop, passive and really tight on the flop, then the surviving hands LAG it up somewhat on the big streets. HU to the river for 8.5 BB.

River is 9 [img]/images/graemlins/club.gif[/img]. Oops, I've been checkraised.

Now what?
