Business chess is a variant of chess played in teams. It was invented in 1992 by Dr. Grachya Ovakimyan of Moscow with the aim of making chess more entertaining and spectacular.〔(【引用サイトリンク】title=Business chess rules )〕 In the opinion of the inventor, free and open discussion between team members and collective decision-making process may make the game spectacular by increasing its dynamism and presenting the various stages of chess players' thinking, evaluation of positions, calculation of variants, choice of alternatives, and so on. In turn, in order to ensure active team discussion and effective decision-making process the ''Interactive Cognitive Scenario'' was developed. Ovakimyan describes this version of chess as a sports business game.〔(【引用サイトリンク】title=Sports Business Games and the Third Revolution in Sports. )〕 == Key ideas == * Branch – version of a chess game having own rating, that is played on one demonstration chessboard (Photo 2). * Branch rating – a number indicating how important the branch, which is a marks (colored chips), located in the upper part of the demonstration chessboard (Photo 2). The score of each branch is equal to its chess result, multiplied by the rating of the given branch. * Branching – splitting a branch of a single move by splitting one of the existing branches (the "parent") into two and distributing the ratings between the two "child" branches. Different moves will subsequently be made in each branch. This can only be done if there is a free demonstration chessboard. * Selection – removing a branch in a single move in recognition of defeat from a position on that branch, and redistribution of its branch rating between those of its remaining siblings. The opponent team gets points equal to the lost branch rating. * Passing – transferring one unit (colored chip) in a single move from one branch rating to a sibling, with no gain nor loss of points. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Business chess」の詳細全文を読む スポンサード リンク
