1.d4 d5 2.e4!?

1.d4 d5 2.e4!? loool...what a strange move! 2...dxe4 that's the main line.

2...e6 that is french defense and 2...c6 is karo-kan defense..

After 2...dxe4 3.Nc3 Nf6 4.f3 (4.Bg5 is also possible) 4...exf3 5.Nxf3 and now if 5...Bg4 White can play 6.h3 Ah5 7.g4 Ag6 8.Ce5 and the position is not clear..

This line is not popular but it is interesting ...WHAT DO YOU THINK?
