The Monty Hall problem

There are three curtains, an announcer (Monty) and a player (you). One of the curtains contains a valuable prize and the other two are empty: only Monty knows where the prize is. You win the prize if you guess correctly which curtain contains the prize. Initially, you select a curtain. Then, Monty opens an empty curtain that you did not choose. Having eliminated that curtain from contention, Monty offers you the option to select the remaining third curtain as a final choice. Should you switch?
