♟ ChessInsights

Openings — cross-tournament clusters

Every game in the DB replayed up to move 5, then grouped by the position reached. Transpositions across different tournaments and different move orders collapse into the same cluster — something a move-tree viewer like ChessBase cannot do natively.
