3.2. Pairing system used for playing in EL is the Swiss pairing system, except during the playoffs (if applicable).

In case of a draw in the final of the playoffs, the base season standings will decide and if it is still a tie, a decisive match needs to be played. Base season standings are primarily decided by the number of points.

5.1. All teams play one match in every round. If total number of teams is odd, in each round one of the teams gets free point (BYE).


5.2. A team match between two teams is played with two or three players of each team.


5.3. A team match consists of individual matches. In every individual match 2 players meet each other and they play 2 games where they start one game each.


5.4. All games are played using the swap2 rule. Swap2 rule means that the first player puts the first 3 stones (two black ones and one white) anywhere on the board, after that the second player can choose a color or s/he can put the 4th and 5th stones on the board (one white and one black). In this case the first player has the right to choose the color. Only exactly 5 stones in a row wins (diagonally, horizontally, vertically), more than 5 (it is called overline) doesn’t win nor lose, game continues. If neither player has succeeded in making a row of five stones when the board is full or the players agree on a draw then the game is called a draw. Players can lose a game by letting their time run out.


5.5. The time control limit for a game is: i) 7 minutes per player with 3 seconds increment per move, Fisher clock in the base season and ii) 10 minutes per player with 3 seconds increment per move, Fisher clock in the playoffs phase. Game settings: 15*15 board, no undo, rated game, public table, otherwise such game is not valid.


5.6. It is possible to change players during a match. The substitutions must be made by the captain and can not be made during an individual match. It is allowed to make maximum two substitutions during one team match. An alternate player has to follow the pairing of a changed player definitely. For putting the same player back into play only a reverse substitution is allowed, in such case the previously substituted player has to substitute his own alternate player. Such substitution is still counted as a new one. The captains of teams are responsible for the correctness of substitutions. Each game played by incorrectly substituted player will be counted as walkover.


5.7. A player gains 1 game point for each won game (also by walkover), 0,5 game points for each drawn game and 0 points for each lost game.


5.8. A team wins the match if its players gain at least 9,5 game points, then it is awarded with 1 tournament point. A team which players gain exactly 9 game points, gets 0,5 tournament points. A team which players gain less than 9 game points, gets 0 tournament points. If both teams get less than 9 game points (e.g. in case of playing 2 vs 2 players and in other cases), both teams get 0 tournament points.
