The captain was unable to move on any "free" paths. There was, however, one "dark alley" available. The active player had no gold, so he cannot use the "dark alley" option. Is the captain moved to the next sequential board, or is the player forced to "put to bed" all of his remaining corsairs?
That is all.
Correct me if I'm wrong but the rules state that the active player can use the 'dark alley' for no cost if he has no money AND it's the only viable move option.
