What the map shows

Questions before the first map

What does it actually show?

Opening stats from your own games: how often you play each line, the win rate and score behind it, and where that line goes next. Not a database of master games. Your repertoire, as you really play it.

Is this an opening explorer?

An opening explorer built from your own games, yes. The familiar kind tells you what the world plays from a position. This one tells you what you played, how it went, and how often.

How many games does it read?

Up to your whole Lichess or Chess.com archive. You can narrow it by colour, time control and opponent rating first, which is the difference between one map of everything and a map of the games you actually want to think about.

Which lines should I drop?

The map marks the outliers for you: black holes are the lines you lose far more often than the rest of your repertoire, neutron stars the ones you win far more often. Those two shapes are the shortlist. The decision to keep or drop a line is still yours.
