It has been the best program in the world for several years (until 1996), it is still THE reference. The analysis version is very powerfull for analyzing a played or a typed or a loaded game (it can read text files, like does Windames 3D last version).
A little bug : when draughts have 2 capture ways, which start from the same square and get to the same square, the computer choose the way for you.
The last Truus version, which runs under Windows 95 has a huge database, with a lot of masters games. Klas Bor, who made Turbo Dambase, thinks that this database looks like Turbo Dambase database.
Price : 100 Florins for simple version, 225 Florins for analysis version.
