The question is if pushing is more +EV than a raise as I think its obvious folding and limping are out of the question.

I think the Hero and SBs stacks are the biggest factor in the push. If Hero standard raises, SB being the big stack may be willing to put a few chips at risk to try call and push Hero off the hand post flop.

Maybe its just playing scared, but I hate playing this hand post flop against a big stack when I miss.
