forward by Reuben Fine, chessplayer and psychoanalyst. He says that chess
is all about castration and castration anxiety. The King would symbolize
the phalus, and to support this Fine remarked that the King is remarkably
fragile in the game of chess (its range as a piece is low, and the game is
lost if the King is checkmated). He also remarked that young boys learn to
play with their fathers and the father appears as the first opponent to
suplant, so the game would be an "Oedipian struggle". He remarked also the
sometimes very high anxiety suffered by a player about to lose, or after
losing, and he related it to castration anxiety. So to win would mean to
castrate the father/opponent, and to lose would be to be castrated. As
these themes are very masculine, Fine says this explains why there is a so
great sex imbalance. I don't think very much of this decidedly
psychoanalytical theory but mention it here just because someone could be
Of course, sex imbalance happens in so many human activities... Certainly
Fine's theory can't apply to them.

configuration, because, after the end of opening, in the middle game,
virtually all positions are unique. The important thing in pattern
recognition is "qualitative" aspects of a pattern that are common to many
unique configurations (e.g. a weak pawn exposed in an open column). These
"qualitative", "evaluative", "strategic" aspects are what makes Kasparov
still have a chance facing Deep Blue: he analyses qualitative patterns,
Deep Blue just calculates millions of positions per second. But still, Deep
Blue doesn't need to be inferior in this regard forever: it's just a
question of good programming...
