It's not that I think he is deliberately polarised here. It's more that I feel he will do this more often with better hands than with worse hands, but that there are a lot more worse hands he can decide to randomshove.

I am using J7s as my example of a random shove hand because most random shove hands will have ~35% equity (but yes, I have seen people at this level show up with that hand in this spot).

The only huge exceptions are offsuit Ax and Kx.

Even Axs has 30% equity vs AcQc when you consider that he can never have AcXc.
