As played, we're priced into a call here with our $40ish stack and some dead money in the pot. It's about $22.50 more to win $65 here. Nearly good enough odds to call if he flashed us KK.

When the action comes back to him, the two other large stacks have already folded, so he's heads up against us with our $20 left behind. I'm pretty sure he's shoving JJ and QQ here as well (whether or not he would re-raise against a bet and a call ahead of him with JJ/QQ isn't certain though).

But, as Fnord said, the best option is probably to just fold our 25 cent SB investment and move on to the next hand.
