Called preflop.

Hi and welcome to FTR, it's good to have you here. Firstly, don't post results, cut off the hand up to the point where you had to make a decision. Posting results can unduly influence the answers people give.

Secondly, to me the options are to either flat call preflop and C-R AI on an A/K high flop or to shove as you did. Personally with the flat caller's dead chips in the pot, I'm happy to shove it, particularly because the raiser was in the CO so his range is likely to be wider than if he raised from an earlier position. You have good fold equity and even if you're called you'll very likely have some dead chips in the pot.
