Draw rate, wins
Final draw rate was 62.9%.
The three most common game termination causes were:
33.9% - TCEC win rule
32.1% - TCEC draw rule
18.8% - 3-fold repetition
There were 4 crashes in the division, two for Hannibal and two for Nirvana. After they were llimited to 16 threads they became stable and were not disqualified with a third crash. Both were relegated to division 2 in any case.
Moves per game
The game lengths were similar to those in division 2.
Time per game (hours)
The first double RR was bookless, and a summary of the bookless openings can be found in a previous post. Here I summarize the results of the remaining games, with book sequences by guest Nikolaos Konstantakis. 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:
Caro-Kann - 16 times
Sicillian - 15 times
English, King's Indian, Nimzo-Indian, Slav - 10 times
The opening variant was mostly determined by the book sequence. 90.5%
of the game pairs repeated the same ECO code twice, and 85.7%
repeated the same opening variant. In only 2.4% of the game pairs the ECO
first letter was not repeated twice.
Reverse pairs, wins
Again I'm restricting to the games with book sequences.
There were 7 game pairs with a 1-1 biased result.
Reverse pairs, same moves
Here I'm also restricting to the games with book sequences.
Pairs of reverse games diverged very quickly, 45.2% of the pairs
diverged immediately after book, 84.5% repeated at most 2 plys.
Thank you. Insightful and nicely presented.ReplyDelete
