Games are first-class citizens in this atlas, so chess grandmasters and champions are carried as athlete entities alongside physical-sport competitors.
This subcategory groups athletes who competed in chess, the abstract strategy game of the chess family, carried as athlete entities alongside physical-sport competitors because games are first-class citizens in this atlas. Chess grandmasters and champions belong here, while players of other board or card games are grouped under their own game-family categories elsewhere in this tree.
