The Scheveningen system
The Scheveningen system is a system of chess tournaments where each member of one team plays with all the members of the other one.
The Scheveningen system is used as in individual point counting, but also in team point counting tournaments. Moreover, all the participants of one team play only against the other team participants, not playing against each other. The order and colors of the competitors' games are determined by lot according to the table. For instance, let us study the example of Scheveningen system tournament between A and B teams. Team members have a regular number: team A- I - VI, team B - 1 - 6. In the first round, the lot determines which team will play with the white pieces. The players with the same regular number meet. In second round, Team A plays with the blacks. The numbers change the competitors: N1 plays against N2, N VI with N 1. In the third round the colors are changed again and the numbers change the competitors again and so on. (see the table below).
|1 round||2 round||3 round||4 round||5 round||6 round|
|А - В||А - В||А - В||А - В||А - В||А - В|
|I - 1||I - 2||I - 3||I - 4||I - 5||I - 6|
|II - 2||II - 3||II - 4||II - 5||II - 6||II - 1|
|III - 3||III - 4||III - 5||III - 6||III - 1||III - 2|
|IV - 4||IV - 5||IV - 6||IV - 1||IV - 2||IV - 3|
|V - 5||V - 6||V - 1||V - 2||V - 3||V - 4|
|VI - 6||VI - 1||VI - 2||VI - 3||VI - 4||VI - 5|
