The last link is an excerpt from The Psychology of the Chess Player by Dr. Reuben Fine. He says chess players are latent homosexuals, but personally I would not put much confidence in anything Fine had to say. Drawing heavily on the writings of Freud's biographer Ernest Jones, Fine supported the view that chess is an embodiment of the Oedipus Complex, with the father-figure King and powerful mother- figure Queen providing the elements for the player to enact his parricidal fantasies. The pieces, according to Fine, are mostly phallic symbols.
Fine founded the Creative Living Center in New York City and according to his obituary in the New York Times he was married five times, four ending in divorce. Just my opinion: If I'm looking for a marriage counselor I would not want somebody that's been married five times.
