Stockfish finds the mistakes. AI explains the missed idea and what to play instead.
Punish mode makes you find the move yourself. Hints guide you without spoiling it.


Instead of a cryptic +0.8, you get a clear explanation: objective, concrete gain, and risk avoided.

As soon as a mistake appears, you must find the punishment. You build patterns that win real games.

Each error is ranked, explained, and compared to the best move so you know exactly what to fix.
