I don't deny chess is the game with the higher status, but I don't think that's what the term alpha was trying to get at. Alpha here is used in a social context, ie the leader of a pack. Some traits of an alpha, as opposed to a beta, include being aggressive, intimidating, capable of convincing others to join your agenda, and willing to lie for your benefit. It's hard to display alpha traits in a one on one game like chess.
