I think we have to shove. I'm not thrilled, but he certainly has sets and overpairs in his range too, which he calls, and possibly some flush draws, or pair + sd combos and the like. Factor in that he might think we're taking advantage of our image, and I can't fold 2nd nuts. Calling is a problem here too because there's a lot of rivers we don't like. We could end up checking down on bad rivers vs hands we beat. I think value dictates that we just have to move all in, and if he has AK then that's unfortunate, reload and keep trooping.
