World Chess plc (LSE:CHSS), the London-listed chess organisation and official partner of the International Chess Federation (FIDE), is pleased to announce the release of the latest episode of its flagship television property, The World Chess Show.

The Last Word on Cheating in Chess
Episode 6, titled The Last Word on Cheating in Chess, addresses one of the most pressing issues in the sport today: the rise of cheating in online play. The programme will broadcast from 9 September 2025 across 100 markets and over 20 networks worldwide.

The episode features exclusive interviews with former World Champion Vladimir Kramnik, who has become one of the most prominent voices on the subject, as well as Grandmaster Evgenij Miroshnichenko, WorldChess.com's Head of Fair Play, who explains how advanced tools, algorithms and expert analysis are deployed to safeguard the integrity of the game.

Ilya Merenzon, Chief Executive Officer of World Chess, said:

"Cheating has become the elephant in the room for online chess. This episode is about facing that reality head-on, showing what's being done, and why transparency is essential if the sport is to keep growing. We are not afraid to put this issue at the centre of the conversation."

Strategic Importance
The World Chess Show is not only a showcase of the drama, rivalries and cultural impact of chess but also a key element of the Company's broader strategy to reach the largest possible audience. As part of this strategy, World Chess has consolidated all of its products under the worldchess.com domain, creating a single global destination for both play and media.
