How the repertoire adapts to your level

Opponents play differently at different rating levels. For each opening, the table below shows the first position where the opponent makes a real choice, and every reply they actually play there — with its frequency in Lichess games up to 1400 and up to 2000.

Status shows how each reply behaves as the level rises: stays when it appears at both levels, drops when it falls away by 2000, and new when it only shows up at the higher level. A marks a main reply, B a secondary one. This is why RBOT trains a separate repertoire for each rating tier.
