Our take
Fritz has quietly become the most feature-rich training partner you can buy outright instead of renting. The 2026 release leans fully into AI training: the Style Engine and the "Evolving Genius" hint system make solo sessions feel less like grinding and more like playing someone. I'll be honest about the style claims — "Tal mode" plays sharp, sacrificial chess, but it's an impression of Tal, not a resurrection. If you're on Windows and allergic to subscriptions, this is the best one-time-purchase trainer on the market.
Fritz is ChessBase’s venerable play-and-train program, in continuous development since 1991. Fritz 21 (May 2026) ships a 3620-Elo engine, but raw strength stopped being the point years ago — the pitch is AI-assisted training: a Style Engine that imitates Lasker, Tal, Fischer, or Karpov adapted to your playing strength, animated opponents that comment on your moves as you play, “Evolving Genius” AI-hinted training, and bullet and calculation drills.
Its predecessor Fritz 20 (2025) introduced AI voice commentary across 170 board themes; version 21 builds on that. The program costs €69.90 one-time (€49.90 as an upgrade from Fritz 18–20) and includes three months of ChessBase Premium membership.
Pros
- The deepest desktop training feature set anywhere — adaptive sparring, calculation training, animated opponents that comment on your moves
- Style Engine plays like Tal, Lasker, Fischer, or Karpov scaled to your level — gimmicky on paper, genuinely fun in practice
- One-time purchase (€69.90) with no subscription, including three months of ChessBase Premium
Cons
- Windows-only in an increasingly web-first world
- The legend "style" simulation is entertainment-grade — don't expect a true Tal to materialise
- A new paid version arrives roughly yearly, and the upgrade treadmill adds up
