Half of your stack is in that pot--I've only folded once in this scenario. (and ironically actually came back to finish on the final table) (you'd be surprised though how often that hand is actually good) Since this is the $11 tourn I'm calling with half of my stack in that pot. There's too much of a chance you have the best hand.

edit--or if he has a hand like J9 or 93 you have about pot odds so you're calling.

Your mistake was preflop so this is really irrelevant anyway.
