Reminds you of how the kids cheat on tests in college:

An Indian chess player has been banned for 10 years for cheating after he was caught using his mobile phone’s wireless device to win games, chess officials said on Wednesday.

[…]

Mr. Sharma was finally caught at a recent tournament when officials discovered that he had stitched a Bluetooth device in a cloth cap which he always pulled over his ears.

He communicated to his accomplices outside the hall, who then used a computer to relay moves to him, Indian chess federation secretary D.V. Sundar said on Wednesday.
