A method of separating ties in a tournament. To a player’s score, add all the score of all the players beaten and one-half of the scores of all the players with a draw. The tie is split in favour of the player with the higher resultant total. The method was created in 1886 by William Sonneborn (1843-1906) from and[U1] Johann Berger (1845-1933) from Austria. In England, the system was tried for the first time on a higher level at the London B.C.A. Congress of 1889.
