Stockfish analysis
Nexa chess uses Stockfish to review key positions from your Lichess and Chess.com games. It evaluates your moves one by one, highlights where the evaluation swung, and helps you see which mistakes keep repeating.
What the engine reviews in each game
After your games are imported, Stockfish analysis examines critical moments: sharp evaluation swings, tactical errors, and doubtful decisions relative to opponent strength.
You can revisit each game and understand not only the result, but which concrete move worsened your position and which alternative made more sense.
From evaluation to an improvement plan
The goal is not only to look at evaluation bars — it is to spot patterns. If the same kinds of mistakes appear week after week, you know what to train before your next session.
Combine move-by-move analysis with weekly tracking and the opening, middlegame, and endgame breakdown to turn every review into a concrete plan.
