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 in 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 commercial sell needs a permission.
Nowadays I am happily retired and only program when the urge takes me.
