Proper Fen String #164

Closed folksgl closed 5 years ago

folksgl commented 5 years ago

A proper FEN string has six fields as seen here: https://en.wikipedia.org/wiki/Forsyth%E2%80%93Edwards_Notation

Using improper FEN string representations limits the maturity and flexibility that chessboard.js can achieve. Additionally, FEN is a standard. If it happens that you do not or will not implement according to the standard, then please do not use the term.

From the documentation:

Note that FEN notation captures more information than ChessBoard requires, like who's move it is and whether or not castling is allowed. This information will be ignored; only the position information is used.
