Club d’Echecs de la Mossig is a long-running chess organizer in the Wasselonne area of Alsace. The club was founded in 1987 as the Club d’Echecs de Scharrach-Irmstett and later expanded its reach across nearby towns, including Wasselonne and Marlenheim. Today, it remains an active local chess structure with regular training and club activity in the Mossig area.

The club also has a strong tournament identity. It organizes the Open de Wasselonne and states that it has run this event every year since 1997. In addition, the French federation listing shows the club in Nationale 4 and Nationale 2 Jeunes, which confirms its role in both adult and youth competitive chess. This mix of club life, youth work, and open tournament organization gives the club a solid regional profile.

The leadership side is clear as well. The federation lists Jean-Claude Coyne as both president and contact, while recent official tournament regulations also name him as the organizer. That makes him the strongest main contact person for this organizer profile. The club also maintains an official Facebook presence under the handle cemossig, which aligns directly with the club name and current event activity.
