You do need to be an expert programmer to understand this book.The code is written as simply as possible.The code is designed to be simple even for intermediate and even novice programmers.
If you are not a programmer, but am interested in chess, this book may be of interest.
The book includes annotation of the source code for a complete chess engine the author has developed as a teaching tool.The complete source code is available at GitHub. The program can be compiled using a freely downloadable compiler.You can alter the code and see if you can make it stronger.
The program is a derivative of my program referred to in my earlier book How to Write a Chess Program, which did not use bitboards. The book explains how bitboards work and some of the many ways they can be useful in programming. The bitboard version runs considerably faster and is consequently stronger.
Alternatively you can simply download the exe file and run the program.
The engine is strong enough to beat most social players.
Features of the engine include:
And much more...
My other books on computer chess are How to Write a Chess Program, The Joy of Chess Programming and Think Like a Computer.
