I'm sure most people know about Emil Joseph Diemer. He was the player who revised Blackmar's gambit (1.d4 d5 2.e4 dxe4 3.f3 ?! ... 3. ...e5 ! ) to include 3.Nc3. Diemer had many beautiful games with his gambit (including tons of miniatures). He even published a book on the gambit (It's been a while ... the spelling might not be correct.), Vom Erstem Zug An Auff Matt (Towards Mate From The First Move).
The book only in included games with 4.Nc3 Nf6 5.f3 exf3 6.Qxf3, however. Over time, 6.Nxf3 (!), replaced 6.Qxf3.
Back to the story ...
Diemer had many games to test out the gambit with Gunderam (I believe, a fellow German and strong player).
Gunderam unveiled this astonishing variation against the maestro himself (7. ... Ne4 !?)
Here is a typical crazy line.
I'm sure the game is full of mistakes, but it is still quite beautiful.
The game was in BDG World March 1988.
In Gunderam's own book on the BDG he gives 9. ... f6.
Later, the entire variation was proven to be unsound, but who cares.
It is a beautiful variation rich in tactics and a joy to look at.
Variations like this are seldom seen today (because of all the darn computers ... They really took a lot away from chess.)
For those interested, here are a few flaws.
8.Bb5+ (!) c6 9.0-0 is good for white.
11.dxc5 Na6 12.Nxf7 (!) and white seems to survive.
I will show one more draw with 12.a4 before this opening variation is put "back in the casket" so to speak. 🙂
