LONDON, England (WTHR) - The age-old game of chess has had a quirky makeover in the World Dive Chess Championships which took place in London yesterday Saturday.
Players use a magnetic board and magnetic pieces and, while the rules remain the same, the playing environment is a little more challenging.
Players are only able to make moves while submerged without any breathing apparatus in a swimming pool.
Once players have dived under the surface they cannot come back up for air until they have made their move.
The unusual hybrid of chess and water sports incorporates a physical element into chess to make it more fun and quirkier.
The tournament is played over four rounds with each match lasting up to an hour, but average games take around 30-to-40 minutes.
