If you want to get serious about the BDG, you'll want to check out the new Diemer Memorial Club. It promises to become BDG-Central for fans all over the world. It features email tournaments to test and improve the opening. A Bogoljubov thematic is underway, with Teichmann and Tartakower-Gunderam thematics to start over the next few months. There will be databases, theoretical articles, and a discussion forum.
Membership is free, but the club is looking for committed players.
Check out the Diemer Memorial Club . I'll try to add some supplemental games in PGN format for anyone interested in exploring the variation featured in the game. This replaces the Forum, which was difficult to implement on another server, and drew little attention anyway. If GeoCities ever straightens out its FrontPage implementation I might revisit this later. I printed that game and another and wondered which was really Diemer's first.
