    Chess Tournaments (Windows setup)

    This is a chess program to help you to organize any chess tournaments

    This is a chess program to help you to organize any chess tournaments without using real chess rules, go to the support page of this program. The support page also has more information about this program. This program creates a "Data" folder to save settings of this program and notes of tournaments and players. Players could play with each other on a single device or playing by multiple devices by a network. This program shows squares that mouse points on them and that helps to prevent any mouse mistakes that happen when playing chess by computers! Although you could do moves by keyboard too. This program has all the functionalities that you need to manage a database, but you cannot analyze games by chess engines or creating variations for them. This program has all time controls in chess clocks, but if you need more complex time controls, you could use them as well, because this program allows you to start a game from any position by two different time controls.
