But in 2007 the Mind Sports Olympiad was reduced to a much smaller venue in Potters Bar due to no sponsorship and no advertising.

[25] As of 2012 the board running the MSO along with David Levy[20] are Tony Corfe[26] and Etan Ilfeld[20] The Olympiad's logo depicted Ajax playing Achilles, used for their medals and awards[27][28] is based upon the famous depiction found on over 150 items of ancient pottery from around 500 BC .
