Transcendental Chess of one side can be any of 4²×6!÷2² = 2880. There is no castling. On the first turn a player, instead of making a move, can transpose any of two pieces on the back row. In Chess960 the back rows are mirror images, but in Transcendental Chess the setup of black and white is different 2879 out of every 2880 times (there being a 1–in–2880 chance that both sides will draw the same setup). This can create inequalities in the position. One way to equalize these inequalities is to play a couplet: the players play two games, one each as
Business chess describes this version of chess as a sports business game. The board, pieces, their positions and rules of movement are the same as for standard chess. But several parallel branches (versions of the same game) can be played at the same time on the several boards, with the help of rating (importance) indicators of a certain branch (red marks on top of the board, see Photo 2). The game is for two teams, recommended each to have five members. During the game members of one team may discuss it, as well as actively move, and then form the alternative (parallel)
