Oh great, not another thread promoting a terrible move....
h6 does nothing to address any of the opening principles at all even remotely. It goes against every single one of them. GO back and review them please.
It doesn't control the center and its insanely passive.
Just play regular openings. Honestly, you won't find a startling novelty that can possibly be any good. Follow the basic opening principles and play sound moves.

Can't find any information about this defense.
1.e4 h6
Seems like a good idea to me because after
2.d4 g5
white probably won't play 3.Nf3 because of the pawn on g5.
My chess program plays
3.h4 gxh4
4.Rxh4
It seems like a bad idea to play 4 Rxh4 because now white can't castle kingside.
