I would say you can fold this hand. Some players will try to make that move, show over lots of weak hands and when they finally do get a monster they do the exact same so they are looking "weak". Since it is early on in the tourny just let it go. Its not the only big hand you are going to get. Like you said chances are you are 50/50. Wait until you have a made hand and then stick it to him. Donks like that usually dont last very long.
