Part of the reason that is standard is to avoid spots like this. But you got one of the few flops you were hoping for so AP pile it in and hope they don't have some KJcc type ****.
Yeah, fold pre. Stacks are nowhere near deep enough for this to be profitable.
Once you get to the flop, never folding obviously. I prefer calling over shoving because you have basically zero fold equity against U1 with $40 behind for the side pot, and you should want CO to call behind to add more money to the main pot giving you a better ROI if you hit. Even if CO shoves himself, that means he was probably never going to fold had you shoved, and you are still getting the right price to call.
