I am a German Webmaster and C++ Programmer. I started chess programming in earlier years around 1985 with the well known home computer C64 in basic, tried also in pascal language, much later around year 1995 i began to learn the C programming language to write my first chess engine EnginMax for Winboard, add also the UCI Chess Engine Protocol . In 2004 i started to write in C++ my new UCI Chess engine Tornado from scratch, which is based on bitboards, after this it is replaced with the magic bitboards.
Tornado is a UCI chess engine without an own graphical user interface.
That is only run in console mode, that needs to play a chess GUI like
Arena, Fritz, Shredder, ChessMaster, and other GUI who using
the Uci protocol to send and get commands from the engines.
This software is freeware, there is no warranty of any kind.
You can give a copy for your friends without any changes on the files,
any changes or using for comercial sell need a permission from me.
