3...d5
1.e4 g6 2.d4 Bg7 3.Nc3 d5!? A surprising
move. Black tries to play a Scandinavian-like
system in which White already have played
Nc3.
[ 3...c5 A rather dubious system 4.dxc5
A) Due to the bad results achieved in the
main line, Black started looking for a refuge
in this line. At the cost of his fianchettoed
bishop Black worsens White's pawn
structure. Of course such an action involves
some risks. 4...Bxc3+ 5.bxc3
