2.Ke2, the Indian Gambit, is not really a sound answer to Alekhine's Cloud, but for a beginner it's acceptable.
5.g4 is the Indian Gambit mainline as it hampers Black's thematic f5 advance.
8.g5? loses another pawn for nothing. It was better to avoid moving the king to h4 in the first place and play h4(with a g5 bind), then Nf3(optional), Kh3 and finally g4-g5.
After some wavering tactical play by both sides(complex but White came out with an advantage in the end) 29.Kg7!! and nothing can stop 30.Kg8 winning the game.
A devastating variation of the Bongcloud.
