The UNIX chess program (/usr/games/chess) has some undocumented commands which have been around since v6 or earlier. One of them is "manual", which lets you play both sides of the game. It's useful to see a position. If someone posts a scoresheet in a notation which "chess" can understand, you can start up an editor, and - put each half-move on a separate line - stick a blank line between each line (g/./a ) - insert a line saying "manual" at the top and fire it off to /usr/games/chess, producing a running visual play-by-play of the game. Other interesting commands are "remove" (whether in manual or game-playing mode), which lets you take back a move; and "hint", to ask the machine what it would play now.
