Chess Coach

Find the mistake you keep making. Then work on it.

Chess Coach analyses your recent Chess.com or Lichess games with Stockfish, finds the mistake that costs you most and builds a coaching plan for it, from your own games.

Coming soon for iPhone. Works with your public Chess.com or Lichess username, no password.

The focus screen: Tactical awareness suggested, a forcing reply in 9 of 47 games

Screens from a test build, with sample data.

You make all kinds of mistakes. Which one costs you most?

Hard to say from memory. So it's tempting to train what everyone trains.

  1. Missed the forcing reply9
  2. Piece left to be taken5
  3. Stopped one move early4
  4. Low clock after a long think3
  5. Miscounted an exchange2
  6. King still in the centre1
Games with each mistake, from 47 analysed games. Example.

Another opening course.

If your games slip away later, in the same kind of moment again and again, more opening theory won't reach it.

Another hundred random puzzles.

Random puzzles keep you sharp in general. They aren't chosen for the moment you keep getting wrong.

A sprinter with a slow start doesn't fix it by running more laps. They train the start.

Chess Coach does that for your chess.

We find the mistake that costs you most.

Stockfish goes through your last 50 games and looks at six areas, from opening to time. One comes out on top, with the count behind it: a forcing reply you allowed in 9 of 47 games.

Your six areas

Test build, sample data.

Then we go deep on that one thing.

Not a general course. The positions where it happened, taken from your own games. Find the move first, then see what you played and what was better.

Your own positions: find your move, then see the best one

Test build, sample data.

A coaching plan built around it.

Seven or eight steps and one cue to play with: your positions, themed puzzle sets on Lichess or Chess.com that match this mistake, games to play with the cue and a review.

The plan: step 1 of 8 with the cue

Test build, sample data.

Then see if it's working.

A recap shows the work you did and how that mistake compares with your earlier games. Then a fresh look, and the next focus.

Stretch finished: 6 of 8 steps done
