Depending on how many ultra-shorties there are, I think this is a call. With 5 people left until the money, you probably won't make it without doubling up at some point. In this spot, you should have the right pot odds to call here, as long as the pfr doesn't have a better king. I think you call here, risk it at the wrong end of a 60/40 and hope to give yourself a chance at making more than the min payout, rather than delaying your all in to try limp into the money.
