A private chess club · entry by diagnosis

The chess club for people who don't have time for a chess club.

Different games. Same pattern.

We read your real Lichess or Chess.com games, find the one pattern quietly costing you the most, and prescribe the master whose chess is its antidote — trained from your own positions in five minutes. The club that fits between your games, not instead of them.

  1. 1Find the pattern
  2. 2See the evidence
  3. 3Train the antidote

No account. Stockfish runs on your device — your games are never uploaded.

Then we prescribe the master whose chess carries the antidote.

The uncomfortable truth

Your rating plateau is not a mystery. It is one pattern — and it can be closed.

The loose piece, the missed dagger, the won ending that slips away: the same mistake, game after game, hiding in plain sight. We read the games you actually played, name that pattern, estimate your ELO and tell you which strengths to keep. Then the real work begins: a legendary master trains it shut with you, teaching from his own games.

  • Nothing invented

    Every claim points to a move you actually played — game, date and opponent you can check. No AI making things up about your chess.

  • Same games, same verdict

    A chess engine analyses everything right here in your browser. Run it twice and the diagnosis is identical — check us.

  • Real genius, never faked

    Masters speak through their real games and human-written lessons — never a chatbot in their name.

See it before you try it

This is what your verdict looks like.

A moment, cited

A real amateur game (Lichess, 2026). White grabbed the b5 pawn with the knight — and lost the piece to it. The position asked for d5, breaking open the centre. Red is what was played; blue is what the master teaches.

And the master speaks

Nimzowitsch

Nimzowitsch · The Prophylactic Mind

“First restrain, then blockade, and only then destroy. Patience is a weapon.”

Your verdict names the pattern, prices it in ELO points, and seats you with the master whose style is its antidote — his voice on every move you review.

Before you ask

The short version.

Is this just another engine that lists my blunders?

No. Stockfish finds the moments — that part is plumbing. The product is the master who cures the pattern behind them, and the discipline of training under one style until the pattern closes.

Do you use AI to analyse my games?

Never. Diagnosis is a deterministic chess engine plus curated, human-written content. Same games in, same diagnosis out — no model inventing wisdom about your chess.

Are these real masters?

The games are real and public, always cited to their true players. Long-deceased masters appear under their own names; the remaining seats belong to original ARCHETYPES — fictional coaches who teach a real school of chess without representing or impersonating anyone. No master ever speaks as a chatbot.

Do I need an account?

Not for your first diagnosis. Paste a Lichess or Chess.com username and meet your master in under a minute.

Which sites do you support?

Lichess and Chess.com — the games you already play.

What if the price goes up?

Yours won't. The founder price is frozen the day you bet on us: as long as you keep your subscription, you'll pay forever what you paid on day one — no matter how much it rises for everyone else.

Stop studying at random.

Find the one mistake — and the master who'll fix it.
