It includes tutorials by Bruce Pandolfini, who writes very accessible books on chess strategy. It even does some of the work of a chess coach, analyzing and annotating your games for you, so that you can go back and learn from your mistakes. This is the chess program I recommend most highly. It does lack some of the features I would like, such as a set with animated combat, but overall it's a great program. This is the original chess program with animated combat.
Pieces move by walking to their new squares.
Pieces capture with animated combat that is also humorous. It's an old program with grainy graphics, but the animation is still lots of fun, and best of all, it is freeware and no longer a commercial product. You can download it for DOS or for an Amiga emulator. The Amiga version has better graphics, because Amigas had better graphics back then. This is the successor to the original Battlechess, and it is presumably still commercial.
