The tournament was divided into a preliminary round and a final round. The eight participating teams first played a simple round-robin tournament . The first four played for the title in Poule Haute , the last four in Poule Basse against relegation. The total of the team points (2 points for a win, 1 point for a draw, 0 points for a defeat), then the number of board points (3 points for a win, 2 points for a draw, 1 point for a one loss, 0 points for an uncompromising loss). For the final placement, both the points from the preliminary round and the points from the final round were taken into account.
Game dates
The competitions were held on September 27, October 18, November 8 and 29, December 13, 2009, January 24, February 7, March 7 and 21 and April 25, 2010.
Preliminary round
While three teams with the first team of Le Cavalier Differdange , Cercle d'échecs Dudelange and De Sprénger Echternach had already qualified for the Poule Haute before the last round, the decision about fourth place was only made in the last round. In the end, Gambit Bonnevoie qualified for the Poule Haute by one board point.
Differdange and Dudelange had the best starting positions with 12: 2 points each and won the first two competitions, so the direct comparison had to decide in the last round. Due to the better points on the board, Differdange would have been enough to draw, but as in the preliminary round, Dudelange won and became champions.
