Chess and Freedom

At My Scribblings For His Amusement, Scott uses chess to argue that freedom is not simply defined by opportunity, but also by consequence.

In the game of chess, there are twenty possible opening moves. Once one is made, there are many more possible second moves, depending on that first move. Other moves will have been denied you by the very fact of that first move. Would it then make sense to say that your freedom is intact only so long as the board remains at status quo ante?
