[edit] Grünfeld Defence - Nadanian Variation

[edit] 5. Na4!?

This strange looking move was first employed by Ashot Nadanian in 1996. Usually it is not recommended to put a Knights on the edge of the board, but here it is meaningful. White takes the important c5-square under control and going to banish black's Knight from the center with е4 move. In the further the a4-Knight can occupy the c5-square and attack the pawn on b7.
