Hi. I've finally mastered the ability to write FEN code for chess
positions. They're relatively simple to do...but now I'm trying to
understand how to write down the best variations in FEN code. How do you
do this? Here's an example:

1kr1r3/1b1pn2p/pq2p1p1/4Pp2/Pp3P2/3B2P1/NPP1Q2P/1K1RR3 w - - 0 21

Now, I can setup the board using the above FEN line...but I can't figure
out how to actaully write down the best move from this position using
FEN code. Can anybody tell me how that's done?

It isn't. If you know how to write FEN, you also know that it is used to
describe *positions*, not moves. Moves are written in something called
*algebraic notation*, perhaps you've heard of it.

FEN cannot contain move information. However, the extended EPD format can,
using 'bm'.

especially Section 16.2

Joachim Vaerst

You must use your fen-position description in a pgn-format tag where you
can describe the best move in a normal way

Succes,
Jo
