The big computer chess book

Mas detalles del libro de ajedrez de Data Becker: http://manillismo.blogspot.com/2018/09/ajedrez-por-ordenador.html

https://www.c64-wiki.de/wiki/Das_grosse_Computerschachbuch

Description [ edit ]

It was not the intention of the authors to present a program that plays at the highest level, but to give basic insights into the structure of a chess program and to clearly explain its most important parts and their program structures.
The included program DEMOSCHACH was originally written on a Commodore SX64 and compiled with Basic 64 .

From the blurb of the back of the book:

How does a chess program actually work ? Very few people know which algorithms can be used to teach the computer the royal game. This book provides information on all aspects of chess programming and includes a complete chess program in BASIC that vividly illustrates the programming issues and their solutions. The book is rounded off by a little history of computer chess and a lot of tips on how to play chess against the computer.

AND WRITTEN HAVE THIS BOOK:
Rainer Bartel is a specialist journalist and came across the subject of chess computers to EDP; he specializes in testing chess programs and winning against them. Hans-Joachim Kraas is a computer scientist and active chess player. His specialty is the evaluation functions, which ultimately decide on the playing strength of a program. Together with Günther Schrüfer, also a computer scientist and active chess player, he has developed the mainframe chess program BOBBY, which participated with substantial games at the Computer Chess World Championship 1983 in New York. Günther Schrüfer is one of the best connoisseurs of the algorithms of chess programs.

Reading sample [ edit ]

3.3.3 One-dimensional Embedded Board Presentation
Here we use the technique of embedding. We do not code the board, but an extended board enlarged by two rows to each side. The field A1 corresponds to the index 27, H1 the index 34 and H8 the index 118.

Diagram of the one-dimensional embedded board representation
The numbers indicate the indices of the fields; For example, the field H8 has the index 118.

At the beginning of the program, the fields that do not belong to the board are assigned a unique value (14), which is never changed and identifies them as not passable. This solves the problem of edge detection. The ladies trains to the top right can now be generated as follows:

100 REM DAMENZUEGE NACH RECHTS OBEN
110 REM STANDORT IST S
120 Z=S: REM ZIELFELD
130 Z=Z+13: REM 13 IST NUN DIE SCHRITTWEITE
140 IF BR(Z)=14 THEN GOTO 170: REM UEBER RAND GELAUFEN ?
149 REM FREIES FELD?
150 IF BR(Z)=7 THEN "ZUG EINTRAGEN": GOTO 130
160 IF BR(Z) "IST GEGNERISCHE FIGUR" THEN SCHLAGZUG EINTRAGEN"
170 REM FERTIG

This is obviously the most clever way to generate trains. Also with Springer trains we always land on the extended board, because we have increased it in each direction by 2 fields.

Opinion [ edit ]

Peter : "An exemplary detailed book on the subject of computer chess, you have to understand a bit of chess and be willing to spend a lot of time studying the book.The fact that the examples are written in BASIC V2, makes the C64-BASIC Fan of course (others certainly less). "
