How it works
FEN notation fully describes a chess position in a single line of text: it is used by chess software, game databases, and forums to share a precise position without a screenshot. Simply paste it into the field above to watch it take shape on the board.
How do I read the six fields of a FEN?
A complete FEN has six space-separated fields: the piece placement (rank by rank from the 8th to the 1st), the side to move (“w” or “b”), remaining castling rights, any en passant target square, the halfmove clock (for the 50-move rule), and the fullmove number.
What do the letters in the “piece placement” section mean?
Each letter represents a piece: P/N/B/R/Q/K for pawn, knight, bishop, rook, queen, and king. Uppercase letters denote white pieces, lowercase letters denote black pieces, and a digit indicates a number of consecutive empty squares on the rank.
The position you enter is never transmitted anywhere except your own browser.
