It has been an year since TCEC switched to league format– 32 participants in four qualification divisions with relegation and promotion, a Premier division and a Superfinal to determine the TCEC Champion. The league format has proven superior to any other stage system tried in the computer championship before, bringing balanced chess and maintaining the excitement until the last matches.
A league system with divisions is not a novelty by TCEC, rather it is a well proven system in many sport competitions. Every such league is often accompanied by a secondary event with a different format called Cup. A most logical step is to include such event in TCEC as well.

Each participant will be seeded according to its standing in the TCEC league event with the #1 seed meeting the #32 seed, #2 meeting #31, etc.
The TCEC Cup will consist of a total of 31 matches divided into sixteenth-final, eighth-final, quarter-final, semi-final and final. For an engine to reach the TCEC Cup gold medal it must win a total of five matches. Both participants that lose the semi final will be awarded a bronze medal.
