Chessfriends:
I wish to show the following analysis (indeed not own !) because I wish feedback about the effectiveness of an interesting line of the closed sicilian:
1.e4 c5 2.Nc3 Nc6 3.g3 g6 4.Bg2 Bg7 5.d3 d6 6.Nh3!
Here the theory have a few forgotten this last move and all the effort are concentrated at 6.f4 , 6.Nge2 or 6.Be3 variations !!
