Chess Automatons by Sarah Beth

First, I want to acknowledge Chess.com member, gretagarbo, for all the help rendered to me, especially in researching Ajeeb. I would go as so far as to say I would have had very little new information on Ajeeb without that help.

Second, I'd like to draw everyone's attention to Jane Irwin's "Clockwork Game," a webcomic, or as she terms it, a docudrama, based (with uncanny accuracy) on the Turk.  If you enjoy reading about this pseudo-automaton, visit Jane's pages. I promise, you won't regret it.

Below I've linked all my articles (some may not yet be available).
