Opponents play a four-minute round of blitz chess, followed by a three-minute round in the ring, alternating between the disciplines until one player is checkmated, or knocked out.
In the latest instalment of the BBC's Live the Story series, Christian Parkinson visited a North London chess boxing club to test his mettle in the ring - and on the board.
