There was some discussion in this thread:
Van't Kruijs Opening

Thank you very much for your valuable informations.
So, is there a correspondence between Van't Kruijs Opening and the C00: Lengfellner system (1. e4 e6 2. d4 d6) ? ...
What do you think of the Lengfellner system and is there a game base of this system?

Thank you very much in advance.
