AQ ..who bets the river ?

[fuzzbox]

PP 2/4 6-max NL

I've been pretty aggro of late (both preflop and with CBs), and I've seen villain do a few silly things, but not enough to make me believe he is donktastic.

Hero is button with A[img]/images/graemlins/heart.gif[/img]Q[img]/images/graemlins/diamond.gif[/img]
Villain is BB
Effective stacks about 300

Preflop
1 limper to hero who makes it 20 (I've been making it 16-20-25 a lot). BB calls, all others fold

Flop (Pot 46)
