A summary statistics table of previous stages and seasons.
Draw rate, wins
Final draw rate was 21.1%. This is very low for TCEC, the lowest draw rate in a stage at least since season 7.
The three most common game termination causes were:
65.6% - TCEC win rule
18.9% - SyzygyTB
8.9% - TCEC draw rule
There were no crashes in the stage, quite unusual for a stage with several engines new to TCEC. Well done to the authors and the organizers!
Moves per game
There were 8 games longer than 100 moves, the
longest was 135 moves (Topple - Minic, game 54, Topple won).
Time per game (hours)
There were 2-move book openings in this stage chosen by Cato. The first letter of the ECO codes was
distributed as follows:
engines had a lot of freedom to choose the opening variant. Yet 64.4%
of the game pairs repeated the same ECO code twice, and 62.2%
repeated the same opening variant. In 15.6% of the game pairs the ECO
first letter was not repeated twice.
Reverse pairs, wins
Reverse pairs, same moves
Pairs of reverse games diverged very quickly, 46.7% diverged immediately
out of book, 77.8% of the pairs diverged at most after 1 move. The
longest repeated sequence of moves was 11 plys (Rodent - Cheese, games 4 and 49, Sicilian Alapin variation, two wins for white)
