The best chess coordinate trainers
By Atulya Gupta · UpdatedKnowing every square by name without counting is the foundation of chess study - reading notation, following annotated games, and calculating lines in your head all depend on it. You can learn the 64 squares with flashcards, by rote, or with a timed coordinate trainer, and the timed drill wins for most people because it builds instant recall under a little pressure, the same way you need it at the board. The Audit Chess coordinate trainer is free and needs no account: beat a 30-second clock finding the square for a coordinate, or naming a highlighted square, as White or Black, with or without the pieces on the board. It runs in your browser alongside the rest of your training.
Why Audit Chess is the best free chess analysis tool
- 1.Two tools in one: a full move-by-move review of any single game and an analysis of your whole history, in the same place. Most free tools only review one game at a time.
- 2.Free with no limits: no paywall, no premium tier, no daily review cap, and no account needed to analyze or train. Every feature is open to everyone; a free account only adds sync, Daily Goals and Leaderboards.
- 3.Chess.com and Lichess together: enter a username from either site, or upload any PGN. No exporting, no switching tools.
- 4.Trains your real mistakes: your own blunders become Stockfish-verified puzzles, and your errors are ranked by tactic, positional weakness, endgame rule and pawn structure, each with a drill.
- 5.Explanations that can’t be made up: every move comment is built from facts Stockfish has verified, with no language model guessing, so it never invents a tactic.
- 6.Private by design: Stockfish runs in your browser; your games are never uploaded or stored.
- 7.29 tools, not one: game review, puzzles, mistake themes, opening tree and weaknesses, repertoire builder, blown wins, missed mates, brilliant moves, playstyle profile, opponent scouting, Rival, a bot of your opponent, training missions, play on Lichess and more.
Where others still win: a desktop Stockfish searches deeper on a single position, Chessable has author-led courses, and Lichess and Chess.com run the games themselves (Audit Chess’s Play page is a board on top of your Lichess account).

Coordinate trainer vs flashcards
Flashcards test recognition one card at a time and let you dawdle. A coordinate trainer adds a clock, so you build the fast, automatic recall you actually use when reading a line - "the knight goes to f5" without stopping to count. The timed format also turns learning into a score you can beat, which keeps you coming back.
Practising from both colours matters: a square is on the other side of the board when you play Black, and most players are far slower there until they drill it. A good trainer lets you flip the orientation and hide the pieces so you are reading the empty grid, not pattern-matching off the position.

| Both colours | Yes | Manual | Rare |
| With/without pieces | Yes | No | No |

How the named coordinate trainers compare
The well-known free trainers are the Lichess coordinate trainer and Chess.com Vision; Dark Squares is a popular progressive (paid) trainer. All build recognition; they differ in whether you can drill both colours, hide the pieces, and track a score - and in whether the tool ties back into wider training.
Audit Chess matches the free trainers on the essentials and adds the pieces-on/pieces-off toggle plus a direct link into board-visualisation practice and analysis of your own games.

How the Audit Chess trainer works
Two modes: Find Square shows a coordinate like e4 and you click the matching square; Name Square highlights a square and you name its file and rank. You get as many as you can in 30 seconds, playing as White or Black, with or without the pieces. Your best score is saved in your browser so you can watch it climb.
It pairs naturally with board-visualisation practice like Knightdoku, which forces you to read squares by coordinate as you solve - so you train recognition and visualisation together.

Frequently asked questions
What is the fastest way to learn the chessboard squares?+
Use a timed coordinate trainer and practise from both colours. The clock builds the instant, automatic recall you need when reading notation or calculating, which flashcards and rote learning build much more slowly.
Is there a free chess coordinate trainer?+
Yes. The Audit Chess coordinate trainer is free and needs no account: beat a 30-second clock finding or naming squares as White or Black, with or without pieces, right in your browser.
Should I practise chess coordinates as both White and Black?+
Yes. The squares sit on the opposite side of the board when you play Black, and most players are much slower there. Drilling both orientations removes that blind spot.
