Buy Fritz Chess 17 Steam Edition PC key

Fritz Chess 17 Steam Edition is a chess program for playing, analyzing games and training your opening repertoire. It includes the neural-network engine Fat Fritz, the traditional Fritz 17 engine and tools for amateurs and professionals to study chess.

Chess engines and analysis

Fat Fritz is a neural-network engine based on LCZero technology. It was trained for a year using grandmaster games, and its analysis often suggests human-like, planned moves. Fat Fritz needs a high-performance Nvidia graphics card to reach its full playing strength. The game also includes the improved Fritz 17 engine, which uses traditional brute-force search and evaluation methods.

You can analyze endgames with up to seven pieces and access Let’s Check. Fat Fritz is based on the open-source LCZero project.

Build an opening repertoire

Fritz 17’s repertoire manager lets you create an opening repertoire by choosing the moves you want to play. The selected moves bring their full variations into your repertoire, which is available online from any computer and on the web. You can also use ready-made repertoires, including hundreds of options at simple, club, tournament and professional levels, or load a ChessBase variation tree or a single game for practice.

Drill your openings

Practice by playing through your repertoire while Fritz responds in ways that keep the game within it where possible. Moves initially appear according to their frequency in theory; the system then repeats lines you have not mastered as often. Fritz tracks the size of the theoretical area you have learned and records your progress as points on a ranking list. When you reach the end of a variation, you can continue as a training game.

Other features

Fritz can generate tactical puzzles from your own blitz games with Blitz & Train. The game also includes improved 3D chess boards with real-time ray tracing.
