Description

Chessigma answers chess questions with its opening guides, an opening catalogue and facts computed from the rules of chess. Ask about the London, the Caro-Kann, the Sicilian and 15 more openings to get the main line, the key variations and the ideas for both sides from Chessigma's opening guides, or name any of 3,700 catalogued lines to get its ECO code and moves. Paste moves to identify an opening and see where a game left theory. Paste a FEN to get the side to move, check or mate status, material and every legal move. Paste a PGN to get a summary (players, result, opening, how the game ended) and a link that opens the game on the chessigma.com analysis board, plus a review link when the PGN comes from a Chess.com live game or a Lichess game. Share a Chess.com live game link or a Lichess game link to get a link to that game's full move-by-move review on chessigma.com. On those pages Stockfish runs in your own browser. Also: the daily puzzle with its solution, and Elo estimates with FIDE, Chess.com or Lichess K-factor defaults (Chess.com and Lichess use Glicko ratings, so their real changes differ). No account needed. For chess players of any level who want facts about openings, positions and games. Chessigma does not evaluate positions inside ChatGPT, does not play games, and cannot read your Chess.com or Lichess account: share a game link or a PGN instead.

Tools

7 tools agents can invoke

Summarize a chess game given as a PGN or as plain SAN movetext: players, result, number of plies, the opening and how long it followed theory, how the game ended (checkmate, stalemate, draw by rule, or unfinished or resigned) and the final position. Returns a link that opens the whole game on the chessigma.com analysis board, where the Stockfish engine runs in the user's browser, and, when the PGN's Link or Site tag is a Chess.com live game or a Lichess game, a link to that game's move-by-move review. It never evaluates moves itself and stores nothing.
analyze_game
Read a chess position from a FEN and return facts computed by the rules alone: side to move, status (normal, check, checkmate, stalemate or insufficient material), every legal move in SAN, the material count (pawn 1, knight 3, bishop 3, rook 5, queen 9) and the opening name when the position is a catalogued opening. This tool does not evaluate the position and does not choose a best move: the Stockfish engine runs in the user's browser at the returned analysisUrl (full analysis board) and bestMoveUrl (best move finder) on chessigma.com.
analyze_position
Estimate 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.
calculate_elo
Get Chessigma's daily chess puzzle: today's by default, or a past day's via date (YYYY-MM-DD, from 2024-01-01 to today in UTC). 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 replies at odd ones. Do not reveal the solution unless the user asks for it. If today's puzzle is not out yet, the latest one is returned: check date. playUrl opens the puzzle on chessigma.com.
get_daily_puzzle
Identify the chess opening of a move sequence, given as SAN movetext ("1. e4 c5 2. Nf3 d6") or a full PGN. Returns the ECO code and name from a catalogue of about 3,700 named lines, how many half-moves (plies) followed known theory from move one, the first move that left it, a link to Chessigma's trainer when the opening has one, and a link that opens the moves on the chessigma.com analysis board.
identify_opening
Look up a chess opening by name or slug (for example "London System", "Caro-Kann" or "sicilian-defense") and return Chessigma's guide to it: the main line in SAN, a short summary, up to four key variations with the idea behind each, the strategy for each side, strengths and weaknesses. Full guides exist for 18 popular openings; any of about 3,700 catalogued opening names returns its name, ECO code and moves. When nothing matches, found is false and suggestions lists close names. Links open the opening's trainer and the analysis board on chessigma.com.
get_opening_guide
Turn the link of a public Chess.com live game or a Lichess game into a chessigma.com link that imports the game and opens a move-by-move review, computed by Stockfish in the user's browser. Nothing is fetched when this tool runs: the game is read from Chess.com or Lichess only when the user opens the link. Chess.com daily (correspondence) games are not supported; ask for the PGN instead.
