David Wight won this Blackmar-Diemer Gambit vs “evgeny1955” in the BDG Euwe. This variation may be good for Black in theory, but it is terrible in practice. White has a huge plus score. Black can easily fall prey to a winning combination at all levels of play.
White has a kingside attack that flows naturally. Prime targets in Black’s position are nine squares from f6 to h6 to h8 to f8 and everything in between. The White army aims at these squares with obvious strong threats. Both bishops take aim. The queen arrives diagonally from d1, d2, or e1. The Nf3 knight hops to g5 or e5. The Nc3 knight moves to e4 for reinforcement. The Rf1 may capture the Nf6 followed by Raf1. David Wight missed the bishop sacrifice Bxh7+ on moves 10 and 11. But by move 12 Wight realized it could work. Sure enough, he won!
