I'd have to put him on a pair with that play.. I can't really see calling that. I would have just called the all-in and seen a flop. You will hit that flop about 1 in 3 times and you have odds for that. Then you can proceed to take on the CO.

Here's a question: if you would have just called the AI, would the CO have an opportunity to reraise? I think he wouldn't because its an all-in.
