=EPD Syntax=
One EPD string or record consists of one text line of variable length composed of four fields separated by a space character followed by zero or more operations. The four data fields, which describe the position, are common with the [[Forsyth-Edwards Notation#FEN Syntax|FEN-Specification]], while the [[Halfmove Clock|halfmove clock]] and [[Forsyth-Edwards Notation#Fullmovecounter|full move counter]], obligatory in Forsyth-Edwards Notation are replaced by optional '''hmvc''' and '''fmvn''' operations, and 0, 1 are their default values <ref>[http://www.talkchess.com/forum3/viewtopic.php?f=7&t=70048&start=5 Re: Fun challenge for best cool code] by [[Harm Geert Muller]], [[CCC]], February 28, 2019</ref>.
