Blackmar-Diemer Euwe Torning

Richard Torning won a Blackmar-Diemer Gambit. I recommend the continuation 1.d4 d5 2.e4 Nf6 3.e5! with big threats. And below Tim McGrew used to play 9.Qe1. Rick wrote:

Blackmar-Diemer Von Popiel Bg5

An alternative to the Blackmar-Diemer Gambit 4.f3 for White is the Von Popiel 4.Bg5. White threatens to capture 5.Bxf6 followed by regaining the pawn 6.Nxe4. Here Black defended e4 by 4...Bf5. White may consider 5.Qe2 or 5.f3 Nbd7 6.g4. The players had chances in the game between Cristobal Barranco Montilla and Joaquim Borges Ayats.

Barry Attack Knight Adventure

This Barry Attack borrows a motif seen in the London System vs Gruenfeld Defence. A bishop and knight gang up on c7. White's knight travels from Nb1 to Nc3 to Nb5 to Nd6 to Nxf7 to Ne5 for the win in a game between Aleksandar Indjic and Abhimanyu Puranik.

Blackmar-Diemer Gambit 5...c5

This Blackmar-Diemer Gambit would normally arise after 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 c5. Here "anon4" played yet another unrated blitz game against IM Michael Mulyar. White treated the position as if it was a BDG Bogoljubow 5...g6. The mysterious "anon4" pressed the attack and eventually busted through on the f-file for checkmate.

Lev Zilbermints has played his Englund Gambit Variation 1.d4 e5 2.dxe5 Nc6 3.Nf3 Nge7 successfully for many years against all levels of competition, especially in blitz. Here the grandmaster playing White had a temporary blind spot on e4 - not once but twice.
