I think you have to raise, probably push. The strength of your cards stems from your read on the maniac. You want to play your 2 cards against his, not other players who may have anything. Of course your position sucks and you'll be taking a chance you are walking into an AA, KK. However the odds are those hands arn't there and hopefully even the other maniacs at the table will note captain sensible has woken up with a push and fold accordingly giving your push some fold equity. Pushing is a calculated risk!

Of course villan will probably flip his 3,6o and catch two more 3's on the flop!
