However, the real decision comes after Monte has removed one of the doors.

Doesn't matter when the decision is made. If either of the two doors has the grand prize, the door he will show you is predetermined. And there's only one chance in 3 that neither of the two doors has the grand prize.

Once you pick a door, Monty ALWAYS has at least one goat to show you.

If there are 100 doors, he will ALWAYS have at least 98 goats to show you after you pick a door, until it comes down to the two doors. ALWAYS.

Here's a Java simulation:
