The second ranked chess player in the All India Chess Federation was banned for cheating with a bluetooth phone that he had sewn into his hat. As technology becomes more compact and wireless, I suppose more forms of digital cheating can be expected.

Implications - Sharma was found with a Bluetooth headset in his hat that his accomplices were using in order to communicate moves via a chess program. The AICF treasurer Bharat Singh Chauhan publicly displayed the cap at the tribunal that decided Sharma's punishment. At the end of the day, it's unfortunate to see such clever technology put to such inglorious purposes. Without a doubt, the authorities at such events will be stepping up their security in years to come.
