Dear Chess Player,

The House of Staunton is happy to bring you Fritz 21, your personal chess trainer. Available to download from May 21, 2026, the new release is a training revolution that adapts to players from club beginners to tournament competitors.

Beyond a powerful engine, it simulates legendary opponents such as Lasker, Tal, Fischer, and Karpov. The engine can mimic authentic styles and tailored ELOs, presenting animated video rivals who comment on your moves. New Bullet Training sharpens calculation under time pressure, while advanced style simulation lets you practice aggressive, positional, or risk‑averse play.

Stronger, more beautiful, and more direct, Fritz 21 delivers champion‑level analysis and personalized training.

Key features of Fritz 21 include:

Personal chess trainer that adapts training for beginners through tournament‑level players.
Legendary opponents: play Lasker, Tal, Fischer, Karpov with authentic, humanlike styles.
Adaptive ELO settings tailor opponent strength to your level for realistic practice.
Animated video rivals that react to and comment on your moves for immersive learning.
Bullet Training mode to improve calculation and decision‑making under severe time pressure.
Advanced style simulation—choose aggressive, positional, exchange‑oriented, risk‑taking, or solid play.
Champion‑grade engine performance with a peak rating of 3,620 ELO.
Enhanced calculation system and new evaluation tools for deeper, more effective training.
