Blackmar-Diemer Olympiad Win

Chess Olympiads allow competition different from normal club or state tournament play. Contestants come from all parts of the world. Players bring together different styles and skill levels. Top levels grandmasters may know each other from tournament events throughout the year. Further down in the standings it’s another matter altogether. Most players are competing against complete strangers who come from other continents.

Blackmar-Diemer Zeller Gambit begins 1.d4 d5 2.e4 dxe4 3.Nc3 Bf5. BDG Accepted is 3…Nf6 4.f3 exf3. Zeller is similar to a BDG but not exactly the same if Black delays Nf6. Anthony Mongiello of the US Virgin Isles won his game against Christophe Batakafwa Biabu from the Congo in Africa. The game saw Black delay the knight until 8…Nf6.The result was not clear until White found Black’s vulnerable king and pressed the attack. The 3...Bf5 line is section 1.5 in my Blackmar-Diemer Games 2 book and in my new Blackmar-Diemer Theory 4 book.
