Moves: 1. d4 e6

1...e6

edit

At this point, it is more likely to transpose into a myriad of 1. d4 openings. What is unique about this move is that it is somewhat of an invitation for white to enter the French.

White can play almost anything at this point, but 2. c4, 2. Nf3 and 2. e4 are the more common replies.
