About the League
​
Each team fields six players ranked from board 1 (the strongest player) to board 6. A match between two teams involves each child being paired up in a game against their counterpart (i.e. board 1 from one school plays board 1 from another etc.) If a school has enough players, they cab field a B-team , in which case their six strongest players must comprise the A-team with the 7th to 12th ranked players making up the B-team. Similarly, the 13th to 18th players would play a C-team, etc.
​
Each child scores one point for their team by winning their game and half a point for drawing. This gives the following seven possible match results: 6-0, 5.5-0.5, 5-1, 4.5-1.5, 4-2, 3.5-2.5, 3-3.
​​​
Matches are played using chess clocks with both players having 20 minutes to make all of their moves.
​​
Alumni are allowed to continue representing their school in Years 7-11 to balance the mix of primary and secondary schools. If they move to another school in the league, they can choose which team they play for.
​​​
The competition is divided into two divisions: Carlsen and Kasparov, with the top three teams from Kasparov promoted to Carlsen and the bottom three from Carlsen relegated to Kasparov. The league is played using a round robin system if there are 16 teams in a division, and a Swiss system if there are more than 16.​
