TCEC is a computer chess engine tournament where chess engines compete in long time controls on strong hardware.
Every game is played from a slightly uneven starting position (“book moves”), to avoid all games ending in a draw.
In order to make this fair, the engines play each starting position twice, once with the white pieces and once with the black pieces.
Reckless won League 1, got second place in the Premier Division, and will now play 100 games in the Superfinal against Stockfish (who has won the last 11 Seasons…).
Time controls are 120’+12".
What does time control of 120 minutes mean? That they have 120 minutes per turn?
120 minutes at the start plus 12 seconds per move.
And in practice this means that out of the first four games:
- the quickest took 4 hours and 18 minutes
- the slowest took 4 hours and 44 minutes

Edit:
- Interview with Reckless developer Arseniy Surkov
- Dev teams agree to Superfinal restart! Regression in nodespeed caused by the combination of a rustc upgrade and the TCEC hardware (2x AMD EPYC 9754 (256 cores/512 threads))
Stockfish devs “[…] encourage adding some rustc / g++ meme to TCEC chat.”
The final starts in 5 minutes.
