Is this a trick question? Raise!

It is very likely that you have the best high hand, and possible that you have the only low. If the other low hand is paired up, you would like to put some pressure on him. Ideally, you'd like him to fold, but good luck with that. Even though your low probably isn't best right now, you have a decent draw to try to outrun the other guy. You have way too much equity to just call.

BTW, your draw is big enough on fifth that I would probably raise.
