But as Monty Hall himself notes, the game show rules did not actually require him to open a door.
> Hall clarified that as a game show host he did not have to follow the rules of the puzzle in the vos Savant column and did not always have to allow a person the opportunity to switch (e.g., he might open their door immediately if it was a losing door, might offer them money to not switch from a losing door to a winning door, or might only allow them the opportunity to switch if they had a winning door).
If the host uses an adversarial strategy, such as only offers a switch when the remaining door is a goat, switching is not necessarily wise.
