Owl Opening Book Tournament 170107

After a long interval, it is time to assess the strength of Cerebellum opening book. The recent SCCT Book Championship XII showed that Cerebellum was the winner from a group of 45 participants running under Chessbase CTG format. This left out other opening books in Arena format. The previous SSCT Book Championship XI was a mixed Chessbase/Arena format with Arena books converted to Chessbase format which obviously is like castrating a bull. The result was disastrous for all the Arena books which were mostly in the middle of the pack including Cerebellum that was also converted from .bin to .ctg.

This tournament is only for Arena GUI. There are few good recognizable  Arena books that are in public, so I had to had to make do with what is available. I also made books out of the CCRL, CEGT, FCP and OWL rating lists to increase the number of participants for sparring.

The results showed that Cerebellum opening book won the tournament. Fishbook Dynamic 170107 was second, Fauzi 2.2 third, HS Grandbook 2.0 fourth, and all the rating list books are in the lower half. However, Fishbook defeated all the participants including Cerebellum. It is also obvious that a general purpose opening book from rating lists are no match to the specially crafted opening books.

Here is the full tournament result:
