The Robatsch (Modern) Defence with 2...Bg7 arises after 1.e4 g6 2.d4 Bg7. ECO code: B06.

This is the standard position of the Modern Defence. Black completes the kingside fianchetto, and the game's character depends on White's next moves and Black's choice of setup. After 3.Nc3, Black typically plays ...d6 (entering the Pirc Defence) or ...c6 (preparing ...d5). White enjoys a space advantage and should develop actively to exploit it.
