netguru. I posted those very moves awhile back. Though the starting position for Bird's Chess is a matter of contention as to where the Guard and Equerry are placed at the start of the game. I used the version from the Chess Variants web page, which Ed Trice dubbed "Wrong Bird's Chess". Assuming you're using Ed's set up for Bird's Chess, I thought it would take 7 moves to transpose the game into Gothic Chess. You say it's five? It has been my assertion about the game being a subset of the other. It was shortly after that post an immense flame war started. It also got some interesting conversation about both games going, so you'll have to wade through a lot different posts to see which apply to your interest. Starts October 14th.

Capablanca Chess was created about 50 years after Bird's Chess in the 1920's. I believe Bird made his game up in 1874. Gothic Chess in the late 1990's. To me, all are the same game. Same pieces, same rules. The starting position greatly effects the play at the beginning of the game, but after 15 or 20 moves it'd be hard to tell which game is which if you chanced upon a game in progress.
