For what it's worth, I think this is a call preflop. While pushing is "playing for first," I would accept a very likely $50 in prize money for eliminating the BB, and then play for first.

Are you familiar with ICM and SNG Power Tools?

If I were analyzing the push, I'd start by looking at the case where you have zero folding equity, i.e. start by looking at calling an open push from the button. In that case, even if he's pushing any two cards the $EV of calling is zero. As you tighten his range, it just gets worse. Then, I'd try to figure out how often he has to fold to make the push profitable. I suppose I'd do something like this: he raises with x% of hands and only calls with y% of hands. Then compare the outcomes.

Yes, I'm waving my hands in the air a bit there, I've never actually worked out that second part.

Welcome to this forum, nice to have you here. I know I like reading your posts in the NL ring forums.
