Two Knights Defence:Fritz variation
9...e4
Hans Berliners move.
This position has been the subject of World Correspondence Championship games. Black has the advantage in development but White has extra material in many lines. It seems White's position is better but finding the correct moves is not easy and many times Black comes out better.
