Read on UTG? If he's been pushing like a good 'un and then suddenly limps, there's a case for c/f the flop. Otherwise, what is his open limping range? Does he do it a lot - and with what kinds of hands?

Against the average shortstack-limper at this buy-in, you're ahead more often than you are behind. He has a random K, underpair, flush draw/straight draw a lot of the time.

You're getting fantastic odds against a much shorter stacked opponent, and if you win you're in a dominating position on the bubble with a shortie giving you licence to abuse.

This is a very easy call unless you have the kind of read that says "c/f the flop", which you obviously didn't because you led out.
