Frequently Asked Questions
How many Stockfish vs Fat Fritz games does this archive have?
This archive contains 82 games between Stockfish and Fat Fritz, sourced from CCRL and TCEC computer chess testing/championship archives (2024 onward).
What time controls were used in Stockfish vs Fat Fritz games?
Games come from official engine testing at varied time controls — classical (90+10, 120+15) and rapid (40 moves in 15 minutes) from TCEC, plus 40/15 testing games from CCRL. Each game page shows its specific time control.
Are these games annotated?
Every move includes the actual engine evaluation from when the game was played: score, search depth, and time used. You see exactly what the engines saw during play.
Can I download a Fat Fritz game in PGN format?
Yes. Open any game and use the Copy PGN button. The PGN preserves all engine annotations and is ready to paste into ChessBase, Lichess, Chess.com, SCID, or any other PGN-compatible tool.
Why does the displayed Stockfish version vary?
Different games came from different official Stockfish releases (Stockfish 17, 17.1, 18). The displayed name simplifies to just "Stockfish" for clarity, while the original version is preserved in the PGN headers if you need it.
How are the games filtered?
Only games from 2024 onward are included, since older engine matches are at noticeably weaker strength than current play. Stockfish-vs-Stockfish games and games not involving Stockfish are filtered out.
How can I practice these games?
Open any game and click the Practice button (next to Analyse). You will be guided through Watch, Manual, and Test modes where you play the winning side's moves yourself.
Can I analyze a game with a chess engine on this site?
Yes. Every game page includes an Analyse button that opens the game in our embedded Stockfish 18 analyser, running locally in your browser at full strength.
How accurate is the engine evaluation shown?
The eval bar uses each engine's own analysis from when the game was played — typical search depths of 25-40 plies for TCEC games and 20+ plies for CCRL games. You can re-analyse with our embedded Stockfish 18 for current evaluation.
Is this archive updated?
New games are added when CCRL releases monthly testing updates and when TCEC publishes new seasons. Latest update covers TCEC Season 28 Final (October 2025) plus CCRL data through 2026.
