What Prepare reads
Four signals turn a game archive into a practical briefing
The report describes recurring public-game evidence. It does not predict what a player will choose in a future game.
Overlap
Where your games meet
Signed-in players can compare the opponent's routes with positions from their own imported repertoire.
Priority
What deserves time
Frequent and relevant routes rise above rare branches so preparation stays focused.
Evidence
Why it is shown
Coverage, sample size, and freshness remain visible so every signal can be judged in context.

Preparation signal
A recurring route
A signal is a repeated, evidence-backed opening habit that may be useful to prepare for. It is not a prediction.
