Analyze Your Chess.com Games on Lichess for Free
Move a completed game into Lichess, use a PGN fallback when needed, and review one turning point before starting the next game.
You lose a close game, suspect one move changed everything, and immediately queue another match. The lesson disappears before you have looked at the position.
My Lichess Analysis extension makes the transition from a completed Chess.com game to Lichess analysis easier. The point is to make review convenient enough that you actually do it.
Here is the workflow, including a manual fallback and a short routine for learning from the result.
Open a completed game
Install the extension in desktop Chrome and open the finished Chess.com game you want to review. Use the extension's action to open it for analysis on Lichess. The Chrome Web Store listing describes its supported workflow.
Check that the players, result, and move sequence match the game you intended to import. Start with a standard completed game when checking your setup.
Use analysis after the game has ended. During a live game, outside engine assistance defeats the purpose of playing and breaches fair-play expectations.
Use PGN when the shortcut does not work
PGN is the text format commonly used to exchange chess games. If the extension cannot read the page, obtain the game's PGN through the source site's game export controls, then open Lichess Import Game.
Paste or upload the PGN and confirm the resulting move list. This gives you a fallback independent of the extension's page detection.
Lichess distinguishes importing a game from requesting server-side computer analysis. Its import page currently asks for an account for the computer-analysis request. Check the options shown in your session rather than assuming every engine action is available anonymously.
The import page also explains that an imported PGN can be public and points to studies for private import. Choose the appropriate workflow before uploading a game you want to keep private.
Review before revealing the answer
Replay the game without immediately asking the engine to explain every move. Stop where you remember feeling uncertain.
Write down three things:
- What you thought your opponent threatened.
- Which candidate moves you considered.
- Why you chose the move you played.
Then compare your reasoning with the analysis. An engine move is more useful when you understand which part of your thought process it exposes.
Find one turning point
A full game can contain enough inaccuracies to overwhelm you. Choose one position where the evaluation changed sharply or where your plan stopped working.
Use this worksheet:
| Question | Your note |
|---|---|
| What changed after my move? | An undefended piece, open file, pawn weakness, or tactical threat |
| What was the alternative? | One candidate move and its purpose |
| What did I miss? | Calculation, threat recognition, time pressure, or a mistaken plan |
| What cue should I notice next time? | A short, specific reminder |
For example, "check which piece becomes undefended after a pawn move" gives you a cue for future games. "Stop blundering" gives you very little to act on.
Follow the line until it makes sense
If the suggested move looks strange, play the main reply and a few continuations on the analysis board. Look for the concrete consequence: winning material, preventing a threat, or reaching a safer position.
You do not need to memorize a long engine line. Try to explain the first useful idea in your own words. If you cannot, save the position and return to it rather than copying the move into a notebook without context.
Evaluation depends on the position and analysis settings. Tiny numerical differences between plausible moves rarely deserve more attention than a clear tactical mistake in the same game.
Make the habit smaller than another game
Before you queue again, record one turning point, one missed cue, and one position to revisit. Review that note before your next session.
The extension handles a repeated browser step. Your improvement comes from the review you do after it. Start with one completed game in Lichess Analysis, or use the PGN import page if you prefer the manual route.
