Motivation[edit]

This property is useful for both amateur and professional players that are playing on lichess.org. Professional and amateur tournaments are played on this site, so this property is of use to easier fetch game results and ratings from different chess sites. Some Lichess users link their profiles on chess.com or FIDE Player database, so it would be possible to (semi-)automatically seed this property. -- Dr.üsenfieber (talk) 20:59, 12 December 2020 (UTC)[reply]
