Every year (except for 2020) since its inception in 1960, the Wachusett Chess Club has held a special tournament to decide the club champion. The formats & time controls for these tournaments have varied widely from open Swiss style tournaments ranging up to as many 12 rounds to restricted round robin style contests preceded either by qualifying tournaments or selective criteria such as a minimum number of games played in a given season, or a "grand prix" style qualification encompassing all the regular weekly tournaments of that season.
Often times the club will hold a secondary "B" or "consolation" tournament cotemporaneously with the primary championship so that players not qualifying for the championship may also play a rated event. In the recent past, these consolation tournaments have been characterized by a field nearly as strong as the championship section.
