QQ against maniac

[jtr]

Opponent in this hand was super-aggressive: 40% VPIP, 11% PFR, and an off-the-scale postflop aggression level. (The actual number was 37, but obviously it's a small sample size -- only 34 hands. So to be fair he might not be a maniac and may have just had some good cards lately.)

On the flop my logic is that I'm happy to see that QQ is an overpair, I check because this guy is so aggressive he's sure to bet it (although come to think of it that's foolish and I probably should have bet anyway and hoped for a raise). Then when he does bet I put in a decent sized raise. He then pushes enough money to cover my stack -- I'm inclined to put him on AJ and call, but is this wishful thinking?
