I guess hero can fold if seat 2 pushes, but probably not, and I really don't see the point of this. Just push.

The one thing I'm considering is a sort of "go and go" move hero could pull if someone decides to call. But, I think in general, he's got more FE preflop by pushing and probably very rarely has FE postflop unless seat 2 smooth calls, which'll be a pretty rare occurence in itself.

Anyway, push.
