About TCEC stages system

Stage 2 consists of the 19 engines that qualified from Stage 1. It is a single round robin where the openings are chosen randomly. The top 10 move on to Stage 3 while the rest is out of nTCEC for the current Season. 171 games are played in Stage 2.

Stage 3 consists of the 10 engines that qualified from Stage 2. The format for Stage 3 is a double round robin and the openings are chosen randomly per pair so that each engine will play both sides of the same opening against each other. The top 6 will move on to Stage 4 while the rest is out of nTCEC for the current Season. 90 games are played in Stage 3.

Stage 4 consists of the 6 engines that qualified from Stage 3. It is a hexa round robin and will use the same book rules as in Stage 3, meaning that the openings are chosen randomly per pair so that each engine will play both sides of the same opening against each other. The top 2 will qualify to play the Superfinal, while the other 4 engines are out of nTCEC for the current Season. 90 games are played in Stage 4.

After Stage 4 has finished, the top 2 engines will meet in a Superfinal of 48 games. This match is played with 24 different openings so that each engine plays both black and white of the same position. The match will be presented with opening 1 used in games 1 and 2, then opening 2 used in games 3 and 4 etc. If the match is theoretically won for one side before game 48, the match will still continue until all 48 games have been played. In the case of a drawn match there will be a Rapid match of 12 games with a time control of 25′ + 10″. In case it is still tied there will be a Blitz match of 6 games with a time control of 3″ + 2′. When the Superfinal is over, the current Season ends.

The winner of the Superfinal will be crowned the nTCEC Grand Champion and will keep this title until there is a winner in the next Superfinal. There is no automatic qualification for the reigning Grand Champion, it will have to go all the way through the next Season for it to be able to defend the title.
