Duplicate source games are counted once. Win rates exclude unknown outcomes. Move frequencies describe only the matching branch of recorded games; results do not prove a move is best. Engine findings use a bounded opening sample (12 games checked) and do not diagnose every phase of play. No reader's own repertoire is used.
