Chess Steganography

If anything the "one-sided" mode is even more fun: https://incoherency.co.uk/chess-steg/oneside.html

It lets you interactively encode a message in your moves when playing against a player who is not in cahoots with you :)

(Disclosure: I made this).

And yeah, sorry about the lack of error-checking. If pretty much anything goes wrong it (maybe) writes an error to the console, and just does nothing.

I'd be interested to see if anybody can produce a short message which can't be encoded because it results in a state where the only legal moves are checkmate.

I'd be interested in the shortest word that can't be encoded in the "one-sided" mode when playing against a strong AI. I played Stockfish as white while having black try to encode "hello" but Stockfish was able to checkmate black before it had finished.

awesome, one just needs to consider to keep the message size below the expected move count for the game required for encoding
