BDG Lemberger vs Alwin van Ee

The Blackmar-Diemer Gambit makes for an interesting choice in thematic tournaments. I played a few. Everyone has to play the same opening from each side of the board in all their games. For some reason I found myself playing the Lemberger Counter Gambit against Alwin van Ee in two games. Both games began with the moves 1.d4 d5 2.e4 dxe4 3.Nc3 e5 4.Nxe4.

In one game I played 4…exd4 5.Bb5+ c6 6.Qe2 Be7 and I lost as Black. See my Blackmar-Diemer Gambit Keybook II, Game 18 on pages 79-83 for more details.

In this game I played 4…Qxd4. Black kept the gambit pawn but his queen and king were vulnerable to White’s active pieces. As often happened in 1996, I agreed to a draw while up a pawn. About this same time, Doug Smith and Alwin van Ee organized a ten player thematic team match between the towns of Gloucester (Smith) and Utrecht (van Ee). The final result was 5-5. One of my own games with Smith is in the notes.

The 4.Nxe4 Qxd4 line is section 2.5 in my Blackmar-Diemer Games 2 book.
