Kevin Sheldrick Wins BDG Euwe

Kevin Sheldrick played a Blackmar-Diemer Gambit that led to checkmate. The line was a BDG Euwe Variation 5.Nxf3 e6. The position in his notes are fantastic with  tactical surprises! My favorite was that checkmate in six on move 15.

Sheldrick wrote: "I played a BDG that had some bizarre tactics. It was on the internetski at the rate of 1 minute each for the game so it isn't of high standard and you may reject it, lol, but I thought it was quite amazing the tactics that Stockfish came up with at moves 9 and 15 so I have sent it in. Bye, Kevin"

Thanks Kevin. I enjoyed this, despite the mistakes due to speed.

I have observed that the 6.Bg5 Bb4 line is most often chosen by mid-level players. They play the bishop pin 6…Bb4 because they are strong enough to see the Nc3 is a real threat. Alas, they are also weak enough not to see the grave danger to their own Nf6.

A far stronger move is simply 6…Be7. It is interesting to note that in this game Black later retreated with 9…Be7. The wasted time gave the White knight a head start on its heroic journey 3.Nc3, 9.Ne4, 16.Nxg5, 17.Nxf7, and 18.Nxh8. All the White pieces are potentially dangerous to Black in the Blackmar-Diemer Gambit. If White can make his pieces dance, Black is in big trouble.

The Euwe 6.Bg5 Bb4 is section 2.4 in my Blackmar-Diemer Games 1.
