This is a pretty easy decision. Here's how I read it. Bigstack is attempting to steal the blinds as cheaply as possible. SB has a very pretty drawing hand, but is too chickensh!t to move allin, and you have a made hand. Push, who cares about FE, you want to get called. With so much in dead chips in the middle, this is a great spot to battle and go for first.

Edit: By the way, there is a small element of the squeeze play here (except you have a decent hand). Frankly, I think I'd rather be called, but if you fold the other two, then so be it.
