It's laughable.
Not laughable at all. A lot of scientific research has been caried out about this specific topic. Here are two examples:
"Twenty-six adolescent boys, regular participants of chess clubs, were compared to a matched control group of 26 non-players. Two cards of the Blacky Test, four fable completion tasks, and three Thematic Apperception Test cards were administered, and indices were constructed to measure three aspects of oedipal dynamics. Chess players displayed significantly more jealousy regarding father's relationship with mother, and significantly more castration anxiety. No significant difference was found in expressions of father-son aggression. A composite index also showed greater preoccupation with oedipal themes in chess players. The results are seen as supporting the psychoanalytic view that oedipal motives contribute to interest in chess."

"On 18 October 1963, Time photographer Julian Wasser took a photo showing Marcel Duchamp playing chess against a totally naked young woman, Eve Babitz. This image became iconic and combines three subjects that were central in Duchamp’s artistic work: art, chess, and eroticism. Using a psychoanalytic approach, I will argue that the chess game, the position of the two characters at the center of the image, and Duchamp’s work of art itself – Le Grand Verre – placed in the center of the photo, refer to the Oedipus complex."

I actually think this is the main reason people can have such an emotional reaction when playing chess, and why you get a lot of jerks on here.
When Freudian theory was still popular in psychoanalysis, a lot was published on the idea that chess is an Oedipal game, in which males act out their suppressed hatred and jealously of the father and symbolically 'capture' the mother. The game represents this by having as its ultimate object the destruction of the King/father, but it avoids confronting this theme too directly in a way that would alarm the conscious mind, since the King is never actually captured and taken off the board, as all the other pieces can be, but only checkmated. The desired 'mother' is the most important piece on the board, being either the strongest ally against the father if it is your own Queen, or the most desirable thing to capture from the army of the opposing King/father.
So what do others think of this theory?
