During play, the board is oriented such that each player's near-right corner square is a light square.
Not all chess games reach an endgame; some of them end earlier. All chess positions with up to seven pieces on the board have been solved by endgame tablebases , [2] so the outcome (win, loss, or draw) of best play by both sides in such positions is known, and endgame textbooks teach this best play.
