Doncaster Chess Association has issued an appeal for more players ahead of the new season.
The number of clubs playing in the league has declined in recent years and officials are hoping to boost membership before the season starts next month.
A spokesman said: “We are particularly looking to attract younger players and also any eastern Europeans who have come over and settled in the area.
“But really anyone is welcome to come along and join a club.
“If they are strong enough, they could be playing in the league straight away.”
In the past the local league has boasted a British champion and also two national correspondence champions.
The current strongest player in the league Bawtry’s Jim Burnett, who plays for the Catholic Club in College Road.
Burnett has also won the Yorkshire Championship three times as well as representing his country in senior competitions.
Other clubs are based at Barnby Dun, Woodlands and Wombwell, and at The Three Horseshoes on St Mary’s Bridge and The Salutation in South Parade.
The Association’s annual meeting will be held at the Rhinos club in Princess Street, Woodlands this Wednesday (7.45pm).
Anyone keen to enter a new team or join an existing club is welcome to attend.
Alternatively they can email firstname.lastname@example.org for more information or to register for the new season.
Trophies will be presented at the meeting to last season’s successful teams.
Barnby Dun clinched a league and cup double while their captain Peter Catt also claimed the Appleby Cup for winning more individual league games than any other player.
Catholic Club won the Bell Cup, where games are played at a faster rate, and Arksey narrowly beat Wombwell to clinch the handicap league trophy.
