Australian Lemberger

In the first round of the just-concluded Oceania Zonal an untitled player gave up 400 points to an IM and still had good chances to win against a Lemberger Countergambit. This 4.dxe4 line is not my idea of fun, and I can’t imagine that either player was totally relaxed in the wild melee that ensued.

Lemberger Countergambit

1.e4 d5 2.d4 dxe4 3.Nc3 e5


The Lemberger Countergambit, not what a Blackmar-Diemer player wants. On the other hand, many BDG players enjoy playing the black side of it--I always did.
