Nice job. Did you ever play the Chessmaster series back in the 90s? It was probably one of the earlier chess game examples where you could play against simulated historical opponents, including Nimzowitsch, Fischer, Lasker, etc.

Yes i did, :) that was a wonderful program, never quite understood why they stopped developing. The nice thing about the chessgate personalities ist you can adapt the playing strength to your level but the style remains consistent.

Agreed! I’d love to see a new version of Chessmaster. Most of my nostalgia is for the 5000 and 6000 series, and they’re notoriously irritating to run on modern machines unless you go through the trouble of setting up a Win9x VM.
