One of the major changes to chess was the augmenting
the powers of the queen. With the augmenting of the queen's power, chess
was transformed in a drastic manner. Now the queen is a major piece in chess
and a powerful ally if used properly. In fact, one of the most beautiful
moves in the game of chess is a queen sacrifice that results in checkmate.
I love playing with chess puzzle books where such a move exists as it adds
to the beauty of this grand game.
