I'm gonna take a little different approach than the others on this hand, even though I already know the outcome and it may sound biased.

You raise to $1.50 preflop, a 6x raise. Let's go back and look at it again.

Preflop: Hero is CO with Q , A .
3 folds, MP1 (Villain)/ calls $0.25, 2 folds, Hero raises to $1.5, 1 fold, SB calls $1.35, 1 fold, MP1 (Villain)/ raises to $2.75, Hero calls $1.25, SB calls $1.25.

He limp RERAISED! Toss your AQ offsuit. In $25NL, a limp re-raise is damn near a guaranteed KK/AA.
