Mellado Trivino Meets BDG Elbert

Juan Mellado Triviño played another Blackmar-Diemer Gambit. For me this was sweet and sour. Sweet because I love to see International Master Mellado Trivino play a BDG. Sour because I do not like the way he handled the move 4…e5. The Elbert Variation 1.d4 Nf6 2.Nc3 d5 3.e4 dxe4 4.f3 e5 implies confusion by Black and sometimes by White. Black may confuse it with the Lemberger 1.d4 d5 2.e4 dxe4 3.Nc3 e5. The line with 3…Nf6 4.f3 e5 leaves Black with a vulnerable knight on f6 and it gives White a combination. 3…e5 and 4…e5 are quite different.

Grandmaster Tartakower demonstrated the win in 1954. White needs to know three moves. White gets a material advantage after 4…e5. Play it this way 5.dxe5! Qxd1+ 6.Kxd1! Nfd7 7.Nd5!! White wins one pawn or two pawns or the Exchange or a rook. IM Mellado Trivino chose 7.f4 leading to an equal position. Unfortunately White got outplayed by Vicenc Esplugas Esteve of Spain.

The line 4.f3 e5 is section 3.0 in my Blackmar-Diemer Games 2 book.

  1. The simple 7 Nd5! Kd8 8 Bg5+ f6 9 ef6 wins easily. All of which proves does not know beans about BDG theory!!

  2. Yes, I played 7.Nd5! all 25 times from this position and won almost all of them up two pawns. The first time I met 4...e5 I did not know White was supposed to take with the King. I took with knight after 5.dxe5 Qxd1+ 6.Nxd1?! and only drew.
