Chess book: Cerebellum_light 170525

BrainFish - UCI chess engine

Information from the author:
Brainfish is a standard Stockfish chess engine extended by a general book format that is capable of handling a reduced part of Cerebellum, which is an innovative chess opening and playing book. In Brainfish, the book moves are only used in engine games, not in analysis mode.

All moves in the published book Cerebellum_light.bin generated by Cerebellum were calculated by using
Stockfish as analysis engine, without using statistics. Then those moves where recalulated by the Cerebellum Library using a graph algorithm that makes all scores in the library consistant. Consistant scores means for example, in case the starting position has a score of 0.2 and a best move is 1.e4, the position after 1.e4 must have the score -0.2. Additionally, some others properties are found, like the best main line of a position and possible Transitions.

Hence, when Brainfish is playing moves that are in the Cerebellum book, it plays like Stockfish regarding the evaluation, only at a much higher skill level. Pondering is only active after the last move out of the book has been played.

The lines in Cerebellum_light.bin are in some cases reaching the late middlegame and endgame.

Isa 2.0.45 - winboard chess engine (Windows and Linux)

Isa - winboard chess engine

About engine: Isa is a chess engine I developp during my free time. Chess programming is my hobby since the 80's years. I started developing with QuickBasic 4.5 (I wrote a weak engine named Bishop) .

Then I learned the C langage and studed the TSCP source code (like everyone I think) .
« Titan » and « DCP » (DCP = Titan + winboard protocol) was born . Strengh was always so weak , around 1400 elo .
After that I rewrote again my engine and Jars came out (I released Jars) and then Yoda (both played around 1800-1900 elo.
After finding dificult to improve , I stopped working on both engines and started to work on Isa , a diferent way.
I started Isa from Firstchess.c source.

Do check analysis later in the game 

The previous patch has added a fraction of the king danger score to the endgame score of the tapered eval, so it seems natural to perform the king danger computation later in the endgame. 

With this patch we extend the limit of such check analysis down to the material of Rook+Knight, when we have at least two pieces attacking the opponent king zone.
