The Top Chess Engine Championship TCEC is heading towards a new season. Season 9 of the competition is going to collect one more time the strongest computer chess software on the planet for a multi-stage 3000+ ELO chess battles. TCEC Season 9 is starting this May 1st and will feature up to 32 participants. See the full participants list here

As of today, April 25th, the engines are undergoing testing. In the cases where problems are found the authors will be allowed to provide bug fixes and updates before the start of the event.

The engines are divided in two groups aka Preliminaries – Stage 1A and Stage 1B. Each of the groups is headed by Season 8 Superfinal participants – the Grand Champion Komodo and Silver medalist Stockfish. The drawing of lots for the other engines is based on tentative rating from the CCRL list and where needed other rating lists. Starting from the Qualifiers (Stage 2) and going into the Candidates (Stage 3) and the Superfinal, “TCEC rating list” will be used. This is also valid for Season 10, right from the start.
