Do you go ~590 and call a shove, or shove ourselves now? Do you ever have reads that would affect your decision one way or another? Does shoving represent a draw better than a half-stack raise?

I'm inlined to shove, but my motivation is the fact that it feels lower variance. Like, winning $430 straight away guaranteed is higher +EV than getting the rest in as a 2:1 favorite, if my math is right. I'm shoving because I want JJ to fold.
