About ChessBlunders
What is ChessBlunders?
ChessBlunders is a training tool that analyzes your actual chess games to find the specific mistakes you make, then turns those positions into puzzles you can practice. Instead of solving random tactics, you train on the exact patterns where you went wrong.
Powered by Stockfish 16, the strongest chess engine in the world, every game you import gets deep analysis to identify blunders, mistakes, and missed opportunities. Then you practice finding the right moves until those patterns become automatic.
How It Works

Analyze with Stockfish
Every game is analyzed by Stockfish 16 to find your blunders and mistakes.
Practice Your Blunders
Solve your blunders as puzzles. Find the move you should have played.
The Philosophy
Most chess improvement platforms throw random puzzles at you. The problem? Those puzzles might not address your specific weaknesses.
ChessBlunders takes a different approach: learn from your own games. Every blunder you make is a lesson waiting to be learned. By practicing those exact positions, you build pattern recognition for the situations you actually encounter in your games.
No ads, no distractions - just focused training on the mistakes that matter.
