How many possible openings are there in the game of chess, if we define an that opening consists of each player making their first 3 moves?

(With one move there are 400 possible openings)

(In reply to Also... by Dulanjana)

Yes, but that information would be available in the current "GameState". In other words, we don't need to know what the previous move was to determine wether or not there is a check, or if a particular move would expose the King.
