FENtastic

ChessUp now supports FEN.

What is FEN? It’s a notation system for representing chess positions. There are 8 parts separated by a slash (/), and each part represents a row. Lower case letters are black pieces, upper case is white, and numbers are how many sequential empty squares there are.

The standard starting position in chess is:

rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR

Of course, you don’t have to know any of this to use ChessUp. But if you do want to see what a FEN position looks like - or create a position and then get the FEN representation - you now have the ability.  Only position information is used.  Info about the game state is ignored.
