Beschreibung
Before the game begins, each player places one Sancho Pansa tile face-up next to his Princiality.

Whenever you have to place one of your open tiles after a position card was turned over, you may substitute Sancho Pansa for that tile.

State that you are doing so aloud and clearly and then place Sancho on the filed in question.

All the other rules remain the same. There is no requirement that you play Sancho Pansa.
