I disagree, with all those callers, if he's up against 2 pair or a set, he's dead to rights, all the equity in the world in a 3way pot wouldn't make up for it. Don't listen to these people. Your fold was ABSOLUTELY the right play here. Your equity and pot odds in comparison to your outs did not justify a call, you were almost certainly a 3:1 dog AT BEST and you could very well be an 8:1 dog against all 3 other hands.
