$5.50 - Re-Raise from Button with QQ, go all the way on A high flop?

[rkidwell]

I was looking to isolate CO with my re-raise here, but maybe I should just push pre-flop? I definitely didn't like the A high flop, but after CO's check, I decided to push and represent a big A. Is there a good chance that CO has an A here and I'm drawing to 2 outs though? How bad is this play?

U have position after the flop,Ilike the reraise maybe to 450.
On this flop I check behind because o the ace,u cant afford a
conti bet and a push is only called by better hands.

I think you have to make a bet on the flop here. T400 and fold to a push. you still have almost 17 big blinds left to get back in the game.
