Chess and cheating. They start with the same first 3 letters, so it makes sense that they go hand-in-hand.
According to The Independent, three titled French players were caught cheating in a fairly elaborate scheme.
One collaborator followed the games on the Internet and used a powerful chess engine to find moves. These would be texted, coded as phone numbers, to another collaborator. This guy would move between tables, the tables signifying certain squares.
The accused are denying it, but have already been suspended by the French national organization.
