How it works

Four steps from “I always blunder move six” to a repertoire you trust.

Pick your opening

Choose a repertoire — Sicilian, London, Caro-Kann — for the side you actually play.

Follow the guided path

A branching map walks you move by move, with a coach explaining the idea behind each one.

Drill with repetition

Lines resurface right before you'd forget them, so the moves stick under pressure.

Track streaks & XP

Daily streaks, XP and stars turn revision into a habit you don't want to break.

The route map

One branching path per opening. You always know the next move to learn.

Every repertoire is a map of connected nodes — each a tiny position to master. The path lights up as you go, so there's never a “what do I study now?” moment.

♟

Available — the next line to learn, pulsing violet

★

Completed — earned one to three stars

↻

Review due — memory fading — time to refresh

🔒

Locked — unlocks as you progress the path

👑

Boss test — prove the whole line end to end

Sicilian · Najdorf★★★

Strike from the side — push your c-pawn to challenge the centre.

1.e4 c5 — the Sicilian

The guided board

A coach on the board. Hints when you stall. Corrections that teach.

A coach bubble explains the idea. A gold arrow nudges the move when you're stuck. Play it right and the line advances; play it wrong and you get an instant, friendly correction — never a wall of engine notation.

✓

Plain-English coaching on every move, not raw engine lines.

✓

A gold arrow hint appears when you hesitate — like a patient coach.

✓

Wrong move? Instant, friendly correction and a chance to replay.

Why it sticks

Spaced repetition built for club players.

Each line has a memory strength. When a node is about to fade, it turns teal and resurfaces as “review due” — exactly the spaced-repetition engine serious players use to keep a repertoire sharp. Built for the 800–1800 crowd who want a real training tool, not a toy.

A day is enough

Short daily reviews beat marathon study sessions.

800–1800

Built for your Elo

Depth that respects club players, not a beginner toy.
