KJo
Probably a good fold. Getting into the pot, you'd have to wonder how much they will pay you even if you do hit your hand. You're not likely to hit a huge hand that will get action if you have KJo. This is particularly true since the effective stacks are short. If you had a read, you could be ultra bold and try to shove to get folds, but this is still probably not a great idea in the long run.
