One on One Match - Cerebellum 170112 vs. Fishbook Light 170112

As mentioned in the previous post, I made this separate match for Cerebellum vs. Fishbook to shed some information about the strength or weakness of Cerebellum and Fishbook.

In my preliminary tests where Cerebellum, Fishbook and Fauzi where the only participants, it is almost without exception that Cerebellum is always at the top followed by Fishbook and Fauzi. It may be strange, but Fishbook defeats booth Cerebellum and Fauzi most of the time. The last post showed that this was the case even when some additional participants were injected. Cerebellum simply is very devastating against "unprepared" opening books that don't take it seriously in the book creation.

The strength and weakness of Cerebellum may be attributed from the following observations:

- Cerebellum book time control is set to 70 seconds per move which is relatively long compared to other books that has considerably less time for each move. Fishbook time control is on average 10 seconds per move. The quality of each move made by Cerebellum is very high and far superior to other opening books.

- The default settings of move selection of Cerebellum is 100% primary strong moves. It means that every move selected in any depth is the one with the highest evaluation score. It does not deviate its moves, therefore its first move as white is always e4 and when it is black the first move is constanstly e5 when the opponent selects e4.

- The secondary moves of Cerebellum can be randomly set from 0 to 100%. But even so, these secondary moves are very close or equal to the primaries evaluation score. These secondary moves are almost as powerful as the primary moves. The secondary first move for Cerebellum as white is always d4. There are no other first moves aside from e4 and d4.

- There is no tertiary or obvious inferior moves for Cerebellum. This is the "Achilles heel" of Cerebellum where Fishbook had the natural advantage of inferior moves.

- Since Cerebellum always choose the best first or optionally secondary moves, it frequently run out of moves when the opponent through the Arena GUI randomly selects the tertiary or even worse inferior moves. The strength of Cerebellum is zapped at the point where this inferior move begins and it has no control to whatever Brain Fish do next which consumes time for each move. If the opponent has enough depth for these series of inferior moves mixed with some best moves in between, it accumulates precious time to compensate for the previous inferior moves. The result is a major time advantage which can be used to recover the lost evaluation scores at the beginning and then may convert this to victory with still plenty of time left.

To make some of the points clear, I created a special subset of opening book from the main Fishbook Dynamic and named it Fishbook Light. This is simply a book that is specifically for use against Cerebellum. It has only one strongest first moves - e4 for white and e5 for black. Despite the presence of randomness controlled by Arena, the first move sequence is always: 1. e4 e5 2. Nf3 Nc3. With Cerebellum, the third move is constantly the Italian Bc4, while I choose Fishbook to use Ruy Lopez Bb5 to deviate. And the real battle begins...

Here is the result of the battle:

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:
