There are currently 3 seperate Divisions: 1, 2 and 3 where 1 is the “Premier” Division. Each Division consists of 8 engines. In each season, 56 games will be played per Division, which means a double round robin where everyone of the 8 participating engines play each other twice. The openings are made so that they are random per engine pair in rounds 1-7. In rounds 8-14 the colors are reversed, with the same openings and pairs, so all in all this means that each engine plays both black and white of the same position versus the same opponent. Note that the traditional scoring system has been replaced with a 3-1-0 system meaning 3 points for a victory, 1 point for a draw and 0 points for a loss.

If an engine currently scheduled to play in any Division has been released in a new version, this new version takes the place of the old version, but only if the Division hasn’t started yet. So during a Division being played, no engine upgrades are allowed. When a season ends, meaning that all 3 Divisions and the Elite Match have been played, the top two engines are promoted to the Division above, and the bottom two engines are demoted to play in the Division below for the next season. In Division 3, the two bottom engines will be replaced by two new engines (or previous engines which has been released in a newer version) so they are out of the TCEC system for the coming season. If necessary, tiebreaks can be used to determine promotions and demotions. The first tiebreak critera is the Sonneborn-Berger. If still a tie, the greatest number of wins decides. In case of still being tied, then the direct encounter between the tied engines decides. If by a miracle they are still tied, then the tournament director decides which engine gets the promotion.

Each game presented on this site is played with a time control of 40 moves in 100 minutes, the next 20 moves in 50 minutes, then finally 20 minutes for the rest plus 10 seconds added per move at this last time control. If an engine loses on time for various reasons the result will stand – hence the game will not be replayed. All opening moves are randomly fetched from a PGN file which contains 215.945 different openings. They are all fixed to 12 moves / 24 plies.
