'Outplaying on the flop' is a bit of a ridiculous notion here. If you flat call the raise, there will be 7,200 in the pot and your opponent has 4,500 left.
If the flop comes ace high and the raiser pushes his remaining 4,500 in, then you may fold thinking you have saved yourself chips by your play when in fact you have folded the best hand. Also the raiser isn't going to fold anything that can beat a pair of tens on the flop, so if you can outplay him here I would like to know how! >:?
Rob the point is there is a chance he passes post flop, there is no chance he is passing pre flop. I am still calling if he moves in unless an ace hits and if the flop comes rags or J hi or something he might check fold his AK thinking he can still make the money. It's like a stop and go, and always worth a go.
Having said that i still move in pre flop because thats just me!
