Depends on the type of player MP2 is. If he is a half decent/strong player, he would likely call the $60 if he had a set, to get money in from you as well. His payout from the other guy is limited because he is practically all in. It seems like more of an isolation play than a value play. He could easily be doing it with KA,KQ,KJ even, considering that MP1 could have raised preflop with a pocket pair and there isnt much risk because he is the shortstack. Unless you have a really strong read, you have to call. Especially in a low limit game.
