Chaos: Oh, I know I could look in the move history, make notes and such. But that is too much work for me. BK could also decide to not show chess boards anymore, afterall "there's the move history". I'll stop playing chess here if the board will disappear.

There are many, many other games (here and at other sites) to be played that don't involve the work that Espionage requires. So Espionage loses, and I don't play it here.
