Britain’s only all-female chess team, She Plays to Win Lionesses A, has achieved promotion to the top tier of the Four Nations Chess League (4NCL), a national competition established in 1994. However, the team faces challenges in complying with league regulations that require each Division 1 team to include at least one male and one female player on its roster. This rule, originally designed to encourage female participation in the sport, now compels the Lionesses to add a male player, potentially displacing one of their eight top-level female competitors.

The Lionesses, comprising players aged 11 to 19, have built a close-knit community since their formation in 2020 by founder Lorin D’Costa, a non-profit aimed at addressing gender imbalances in chess. The team’s promotion marks a significant achievement in a sport where women remain underrepresented; only about 11% of top-rated players are female. Members cite the supportive environment and camaraderie as crucial factors in their development and success.

Emily Maton, 18, a member of the team and an Oxford University student preparing for the upcoming Under-20 European championships, emphasized the importance of the team’s all-female composition. She recalled instances of gender-based disparagement during her earlier years and highlighted the discouragement many girls face in competitive chess. Maton and her teammates argue that being forced to include a male player would undermine the team’s dynamic and discourage continuing female participation at high levels of the sport.

Founder Lorin D’Costa expressed concern that the rule may hinder efforts to engage more girls in chess. She noted that fewer young females participate in chess and that promoting an inclusive and female-friendly environment is vital to fostering strategic skills that are valuable beyond the game itself.

In response, 4NCL’s finance director, Mike Truran, defended the mixed-gender rule as central to the league’s identity and mission. He stated that since the league’s inception, the top division has required mixed teams as a means of actively encouraging female involvement. Truran cited a survey of team captains from the 2025-2026 season, indicating no significant support for altering the rule, although the league remains open to revisiting the policy if perspectives shift. He also noted there is no evidence that the rule deters female participation; rather, the requirement helps maintain a minimum level of female representation in a predominantly male environment.

While the rule aims to promote gender diversity, critics within the She Plays to Win team contend that it inadvertently penalizes an all-female team’s merit-based success. The Lionesses hope a revised approach will be adopted before the league restarts in October so that they can preserve their team structure without sacrificing competitive opportunities for female players.
