Ok...If I was playing, I'd want to keep the sabateur for as long as possible. I mean, this is a guy who's not competing against you to win $500K, right? Who cares if they lock the cupboard or tape up pictures. I could live with that stuff.
The Jewish guy is, IMO, the real twist of the game. There's so many rules he has to observe in that house, I really wonder just how Jewish he really is. what's he gonna do on Friday evenings to Saturday? How's he getting to shul? Technically can he talk into his microphone? He's not allowed to use electricity or turn anything on and off.
