Draw rate, wins
Final draw rate was 78%, very close
to the draw rate of the last superfinal and slightly better than the target rate 80%.
The three most common game termination causes were:
32% - TCEC draw rule
28% - TB position
22% - TCEC win rule
Moves per game
The distribution has a long right tail. There were 17 100+ move games, three of these were decisive, all black wins.
Time per game (hours)
The short increment made sure the game duration would not far exceed 4 hours.
There were variable length book openings in this stage chosen by Jeroen.
The first letter of the ECO codes was
distributed as follows:
If we use the opening 'family name' (using format FAMILY_NAME: VARIANT....) the top 3 are:
Sicillian - 14 times
King's Indian - 10 times
Caro-Kann - 8 times
Spanish - 8 times
This is very similar to the distribution in season 10.
Almost all of the book lines had the same ECO codes in
reverse games, except for one paired game - games 11-12, one was A08 Reti: KIA, French Variation and the other was C00 French: KIA. There were 6 game pairs with different opening variants.
Reverse pairs, wins
There was only one biased openings with two white wins. On the other hand there was one opening where Stockfish won both games, a rare event in superfinals.
Reverse pairs, same moves
Reverse games diverged very quickly, 36% diverged immediately after book, 68% diverged at most after two plys.
