Martian Gambit Question

@Witty_Alien

I want to do some question about this Gambit.

1)If black plays 5...h6 the sacrifice is good or not? Because 6.Nxf7 6...Kxf7 7.Nf3 we try to transpose to the alien if black plays Nf6 but he plays Nd7 and how is this position?

2)If Black plays 8...Bf5 and after that h5 trying to play g6 without g4! and the bishop is trapped? After 8...Bf5 what we play?

3)If Black plays 8...Be4 or Bh7 what we play?

i didn't understand the second and third one but for the first one you do sacrifice like it's alien gambit. the move order is different there

1 the sacrifice is good and you can watch witty aliens video where he explains it

2 what are the moves on move 7?

3 same thing as 2
