[Slim Pickens]

It's really hard to read people's raise/fold fractions, which is what determines the best play here. They seem to be largely random for most players, so I don't see that it makes much difference whether you push or fold there. It's sensitive enough to the ranges that there could be valid arguments either way and there's not a good way to resolve them.

SB would have to put you on a serious case of FPS to make the AJo call correct, and I don't see how the combination of

a) knowing that a call is correct only against a FPS-ing opponent and
b) reading you as such

could possibly exist.
