I'm glad you posted all the stack sizes at the table.
If we shove here from UTG with our 12 big blinds, there's only 2 seats we're really worried about, the 54 bb stack, and the button's stack. We're not worried about the other smaller stacks because they should either be playing super tight with the bubble approaching, or else they should be willing to get it in and double themselves up with quite a few hands that we're either dominating or else we're flipping against pairs.
So there's really only 2 seats to worry about, and I submit that the 30 bb button will not want to call our shove and lose, which will drop them down to 18 big blinds. So the button should be super tight here as well. The only real fear is if that 54 bb stack calls us, but I'm more than willing to take that chance in order to steal the blinds which will earn us enough to get us thru the next orbit.
I shove here all day and all night, and I'm happy about it even if the small blind wakes up with AA. LOL
If I have a very good hand with 15 big blinds, and the UTG with 12 big blinds shoves, most likely i'm gonna fold my hand because I never want to be left with just 3 bigs, I'd rather fold my good hand here and wait for a spot where I can open the action instead. That's why I don't worry about the smaller stacks at the table here, they are gonna basically be folding everything except top 5% hands and those are just a cooler if we happen to run into one of those premiums. The two blinds will be risking half their already-small stacks to call us, and I don't think they call us very often for that reason.
