Around eight years ago I used to read 'Doctor Who: The Internet
Adventures' on the Newsgroups. Here is a brief excerpt from the
multiauthor story: TIMEWAR - Chapter 10 - 'Endgame' by C. A Reed Jr.
* * *
The Black knight threatening the White King and Queen slowly
reformed itself. It lightened in color until it matched the white
pieces, and the figure itself reshaped itself into the image of the
other two white Knights. The only reaction from the old man's
opponent was the tightening of a hand into a fist.
The old man shook his head slowly. 'You really have to know
your pieces before you can use them to their best advantage.' He
moved the reformed Knight to a new square near the other two
Knights. 'I always enjoyed this game more then cards -- a little
less random. Your move.'
