Stage 4 of the strongest computer competition TCEC Season 6 is over and the top two engine Stockfish, modification 300414, and Komodo, variation 1223, qualify to play the Superfinal.
Stockfish topped Stage 4 with 30/48 points, leaving the runner-up full 2 points behind.
Komodo proved its supremacy over Houdini, defeating the latter in the forty-sixth round, thus finishing second with 28/30, 4 points ahead of Houdini.
Critter remained last with 14/48, although he proved to be dangerous in the last part of Stage 4.
The last-year Superfinalists Stockfish and Komodo face each other once again in a match of 64 games.
32 different openings will be played so that each engine plays both black and white of the same position. If the match is theoretically won for one side before game 64, the match will still continue until all 64 games have been played. In the case of a drawn match there will be a rapid match of 16 games with a time control of 25 minutes plus 10 seconds with random openings selected from earlier in the same Season. In case it is still tied there will be a Blitz match of 8 games with a time control of 3 minutes plus 2 seconds. When the Superfinal is over, the current Season ends.
The winner of the Superfinal will be crowned the TCEC 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.
