A summary statistics table of previous stages and seasons.
Draw rate, wins
Final draw rate was 81%.
The three most common game termination causes were:
26% - SyzygyTB
21% - TCEC draw rule
20% - 3-Fold repetition
were no crashes in the stage. One game ended with mate on the board, very unusual for a superfinal.
Moves per game
The games are
longer when NN engines are involved, due to different scoring methods
that delay the application of the win and draw rules. There were 32
games longer than 100 moves, the
longest was 242 moves (Stockfish - AllieStein, game 54, draw).
Time per game (hours)
There were variable length book openings in this stage chosen by Jeroen. The first letter of the ECO codes was
distributed as follows:
engines had almost no freedom to choose the opening variant, 94%
of the game pairs repeated the same ECO code, 92% repeated the opening variant. In 96% of the game pairs the ECO
first letter was repeated twice. A notable exception was the first game pair which was without book.
Reverse pairs, wins
Reverse pairs, same moves
Pairs of reverse games diverged very quickly, 34% diverged
out of book, 68% of the pairs diverged at most after 1 move. The
longest repeated sequence of moves was 16 plys (AllieStein - Stockfish
games 15 and 16, Robatsch defense, pseudo-Austrian attack variation, two draws)
