Ivanov Wins Blackmar-Diemer

Oleg Ivanov won a Blackmar-Diemer Gambit Poehlmann Variation. This line can arise from a Dutch Defence move order, but Ivanov chose the BDG path. His opponent was the higher rated Ivan Punchev in the 181st MGU Open in Sofia, Bulgaria. The game begins 1.d4 d5 2.e4 dxe4 3.Nc3 f5. The Dutch move order would be 1.d4 f5 2.Nc3 d5 3.e4 dxe4. Why not 3...fxe4? Because 4.Qh5+ picks off the d5 pawn.

My Blackmar-Diemer Theory 4 book discusses the details of White's good choices after 3...f5. I like the BDG type 4.f3! When the game opens up White has several potential targets in the Black position. In this game Punchev fought back, but he developed only one minor piece in the first 10 moves. That usually spells trouble. FIDE indicates that Oleg Ivanov of Bulgaria was born in 1952. Many older players find the Blackmar-Diemer Gambit makes games fun. With his performance in this tournament, Oleg Ivanov raised his FIDE rating to 1628.
