11$ speed: Keeping shortie in to keep p0wning the bubble?

[donkraft]

When I played tonight, I was fortunate enough (read: luckboxy) to have a huge stack when 4 handed on several occasion, and I was positively wrecking the bubble.

In this situation, there are no crazy people in the game left, all players are sane.

UTG moves all in [t1580] (this is an ATC-push, I know the player)
Hero?

This is an insta-call if I think straight-up EV for this hand. But keeping the shortie in will let me p0wn the bubble some more (maybe more +EV?), and bleed the others stacks some more. Of course there are also risks...

What are your general thoughts on this? Should I not over think this right now and focus on more basic stuff, or is this important?

Any references to good discussions on this subject?
