Chief developer Matthias Wüllenweber explains in the video how the style report works. Have fun!

ChessBase 18 now provides insights into players that go beyond mere opening statistics. Evaluating players is a somewhat delicate matter, and mistakes could be embarrassing. However, the Style Report hits the mark surprisingly well. For historical stars whose styles are well-known, all the classic clichés are spot-on. Most importantly, you can learn something about your next opponent—or about the most important player of all: yourself.

Chief developer Matthias Wüllenweber explains in the video how the error report works. Have fun!

The error report in ChessBase is a powerful analysis tool that evaluates a player's calculation accuracy based on their performance in games. By analyzing mistakes in various situations—such as complex positions, moments of attack, or defense—the tool not only identifies error patterns but also estimates the player's Elo rating.

The analysis considers factors like position complexity, game phase, and the impact of mistakes to create a detailed profile of the player's strengths and weaknesses. This makes the error report an invaluable resource for both preparing against opponents and assessing personal performance.
