since you know him to be loose and passive you can check and fold to a check-raise. if you had no read, then this is a tough situation. I honestly don't know whether betting and folding to a c/r, betting and calling a c/r or checking through is correct. lately I've been checking through on turns like this, so I can avoid the tough decision. This is NOT the way to play the game, and I'm sure my passivity in such good situation is costing me. My gut says you have to bet the turn, and call down with no read. there are only 4 cards that beat you, and it's a great board to bluff on.

sorry I couldn't be more affirmative. It's definitely a tough situation
