The tendency
Capricorns have real wit and a sense of humor, and they are formidable at the board. They use their knowledge to master every piece, and they are not easily flustered by losing. What they enjoy is beating an opponent so subtly that the opponent is left working out how badly it went.
The methodical, organized style can read as snobbishness, though it is not intended that way. It can also make a long game tiring to sit through, which is part of how it works.
The Capricorn chess life
Capricorns often begin later, around age twenty, and tend to give it up after about a decade. They play twice a week and often bring family into the game. They prefer a slow game, rarely abandon one regardless of the position, and excel in the middle game. Postal chess appeals to the social side, and they seldom show nerves.
Pieces Capricorn favors and fears
They begin with the queen and bishops, then move toward the queen, rook, and knight as their knowledge grows. They trade, but they will not willingly sacrifice for position.
How to play against a Capricorn
Watch your pieces. Capricorns are known to steal a piece while you are not paying attention, and the loss registers several moves later. When they are losing they will work to force a stalemate, so close that door early.
