The position (fen) is given with the solver to move, after the opponent's last move. The solution is in SAN, with the solver's moves at even indexes and the opponent's replcalculate_eloEstimate a player's new Elo rating after a single game with the Elo formula. Pure arithmetic, no chess engine. The system field picks a K-factor default for FIDE, Chess.com or Lichess, but the result is an Elo estimate: Chess.com and Lichess use Glicko ratings, so their real rating changes differ.
