AK - Vs. Reraise all in and a call

[Cleveland Guy]

$10 + 1
About 270 runners, just before the first break we are at about 140 left.

My stack is 2800 - after getting up to 4500 in the first 20 minutes, I
have been card dead over the last 30, and gone back to an average stack.

Play at the table has been normal

Blinds are 75/150. Hero is UTG +1

Hero gets Dealt AK [img]/images/graemlins/spade.gif[/img] , and raises to 450.

MP raises all in to about 1350.

CO who has about 4500 left calls the 1350.

Hero's Move?
