chess24.com was an Internet chess server in English and ten other languages, established in 2014[1] by German grandmaster Jan Gustafsson and Enrique Guzman.

Reviews tended to favour rivals Chess.com and Lichess in terms of the playing experience, while suggesting that Chess24 had richer educational video content, and probably a better interface for tournament monitoring.

[8][6] Chess24 provided live coverage of major international tournaments on the website and also on YouTube with commentary by players such as Yasser Seirawan, Peter Leko, and Tania Sachdev.

This was expanded to form a conceptual tour including the Lindores Abbey Rapid Challenge, and culminating in a Grand Final, featuring Magnus Carlsen and Hikaru Nakamura.

[14][15] The 2021 edition was hosted in March 2021, also online, and saw the favourite Magnus Carlsen being knocked out in the semifinal by Ian Nepomniachtchi, who eventually lost in the final to Dutch Grandmaster Anish Giri.
