FEN is the abbreviation of the Forsyth-Edwards Notation, and it's fully supported in the club.
A FEN text contains one single textual line, which describes a setup of a game, and some other things about it.
In all the details please see here.
We can use FEN lines to start a game from a defined setup.
And for sending in our favorite chess problems also.
