Four-player chess for themselves. As with regular chess, four-player chess begins with fortifications and the of pieces, but opportunities for capturing pieces (and gaining points) come about at large as each of the three opponents likewise do attacks and make threats of capture. Therefore picking friends and enemies has a political quality; ultimately the impromptu teammates will have to combat each other as only one can win. The Cox-Forbes theory of the origin of chess, though debunked, asserts that a four-player version was the earliest form of the game. A description of a four-player chess game is found in an Indian text
John Cochrane (chess player) chess aware of how strong Cochrane was at his peak, and described him as "Father of the English Chess School". During the second part of Cochrane's career in India his main opponents were the Indian players Moheschunder Bannerjee and Saumchurn Guttack. Cochrane's first recorded use of the Cochrane Gambit against Petrov's Defence was in a game against Bannerjee in 1848. Bannerjee's fondness for fianchettoed openings, as reported by Cochrane, eventually led to the Indian defence class of openings. Another game, published in William Norwood Potter's "City of London Chess Magazine" shows Bannerjee playing with the black pieces and beating Cochrane
