Ka1 Qxa3# Internet-based simultaneous exhibitions The internet has allowed for the creation of chess game services wherein people may play an opponent from anywhere in the world. Popular sites such as Lichess may have many thousands of active online games as well as tens of thousands of viewers during any time of day around the world. This new online chess paradigm allows for world class players to be actively playing chess as well as teaching and giving demonstrations. On 13 April 2019, a simultaneous exhibition was hosted by Lichess for International Master Marc Esserman who engaged 100 players. He rapidly moved through a hundred Kings Pawn E4 opening and the matches lasted anywhere from thirty minutes to a full eight hours. Many top level players were involved and the exhibition lasted for just over eight hours. IM Marc Esserman won 82 of the games played with 11 ending in a draw. Tandem simul A less popular variation of simultaneous exhibition is the tandem simultaneous exhibition, also known as leapfrog simultaneous exhibition, where more than one (usually two) experts play a number of opponents, making successive moves without consulting one another.
