Without reads or seeing that he is on tilt/donk of some sort, this is a ridiculously easy fold. If this is a difficult fold for you to make I think you should reconsider playing 5/10. This is not a tournament, you shouldn't have to "coinflip" with people to win money. Even if you are dead accurate and he does in fact have overcards, I still wouldn't call. Sure you are ahead, but who cares, why take 50/50 on half a buyin when you could take much better odds on more money.
