Welcome Retro and Chessmaster fans!

On this site you will find things about  the great Chessmaster and old chess engines. Chessmaster is driven by the great King engine from Johan de Koning. Chessmaster is the most selling chessgame of all time.

The site is new and I will give updates and more from time to time.

As a big Chessmaster fan and want to give my honor to it with this site. My first one was Chessmaster 4000 Turbo.
