I don't know what a "frafra" is. I think this argument ("chosen door can't get
prob. point back") is OK and not a delusion.

We are perhaps talking about different games. NOTE: I don't know about the Monty
Hall show and his rules. I discuss the following "game":

- the candidate chooses one door.
- the host opens a door, but not the chosen one.
- He must open a door!
- The opened door does NOT have the car (otherwise the situation is
uninteresting).
- The candidate is offered to switch

Is this the game which you are discussing, too?

Greetings,
Gerrit
