It's refreshing to see an author actually play an opening he writes about--especially when the opening is the Blackmar-Diemer. In the just completed Luebeck club tournament, Christoph Scheerer, author of the recently published the Blackmar-Diemer gambit, a modern guide to a fascinating chess opening, tried for a BDG in two games. In one game Black evaded the BDG by going into a Hübsch Gambit; in the other Black declined with the Vienna Defense.
Unfortunately, White lost both games and finished with 4 points. His opponents, Michael Kopylov and Vladimir Epishin, along with Henrik Danielsen finished on top with 6 of 9, with the title going to Kopylov on tie-breaks. The game with Kopylov, a Vienna Defense, goes 18 moves deep in a line in Scheerer's book.
