Blackmar-Diemer Vienna Famous Trap

In slow grandmaster tournaments, opening traps are rare. But in blitz, club, and online games we see traps all the time. The Blackmar-Diemer Gambit can be declined with 4.f3 Bf5 known as the BDG Vienna. The most common continuations are 5.g4 Bg6 or 5.fxe4 Nxe4. If Black takes with the bishop by 5...Bxe4, a trap winning the queen is playable. All Black has to do is to see a hanging d4-pawn in the middle of the board and grab it. Blitz players fall for it, as my opponent did in our two-minute bullet game below. This same simple trap can also be found in the BDG Euwe variation. It works!
