rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1

There is no "/" following the last "R".

The "w" (or "b") is lower-case.

The "KQkq" is castling, white flags are upper-case.  If castling is not legal,
there will be a hyphen ("-").

The hyphen following the "KQkq" could also be a square, for instance e3, which
is the target of an en-passant capture, if one is legal.

The "0" is the number of plies (not moves) since an irreversible move.

The "1" is the move (not ply) number.

An obsolete dialect of FEN uses "nil" instead of hyphen.
