Chess

Chess is a board game played between two players. The game is played on an 8x8 checkered grid. Players are able to capture opposing pieces and win by forcing their opponents King into a position where it is attacked and cannot escape or block the attack.

Appearances in Yu-Gi-Oh!
In the Yu-Gi-Oh! universe, Seto and Mokuba often played chess at their orphanage. Gozaburo Kaiba was a chess grandmaster. Seto challenged him to a game of chess, where if Seto won, Gozaburo would have to adopt Seto and Mokuba. In the manga, Seto won the game by cheating. In the anime, Seto won because he had studied Gozaburo's strategies.

In Yu-Gi-Oh! R, Reiko Kitamori uses chess themed "Puppet" monsters. A number of the "Archfiend" series are also based on chess pieces. Both sets of cards have support cards based on different chess moves and positions.
