Exact Figshare tags:
White="Steinitz, William"; Black="Anderssen, Adolf"; Event="Baden-Baden"; Date="1870.07.23"; Result="0-1". LibreChess parsed the main line with chess.js and stores normalised SAN. Source comments, side variations and termination detail were not retained.

LibreChess checks every SAN move with chess.js and compares the result and move sequence with a stored reference. The engine comparison was calculated offline from the fixed settings above; it is not a source for historical claims. No termination is inferred where the imported score does not preserve one.
