The knight is going to d6, White's queen can go to g4, and his play is very easy. Black's next move makes things worse.
1. g1f3  1... g8f6  2. g2g3  2... b7b6  3. f1g2  3... c8b7  4. e1g1  4... c7c5  5. d2d3  5... d7d5  6. e2e4 [%c_effect e4;square;e4;type;GreatFind;persistent;true] A thematic move and the best way to fight for an advantage. White doesn't need to wait for the e4-square to be protected, as it's possible to exploit the h1-a8 diagonal. 6... e7e6 It's better for Black to maintain the center. 7. e4e5  7... f6d7  8. f1e1  8... b8c6 On the board we have a typical pawn structure of the King's Indian Attack. Black has not castled yet, so he can take the opportunity to attack the e5-pawn and advance the kingside, perhaps placing the king on the other side of the board. 9. c2c4 Forcing Black to advance the center and gaining the e4-square for the knight. 9... d5d4  10. c1f4 This natural move is a novelty. 10... h7h6  11. h2h4  11... f8e7 Black prepares the g7-g5 advance. 12. h4h5  12... e7g5 [%c_effect g5;square;g5;type;Interesting;persistent;true] An interesting way to use the g5-square. 13. b1d2  13... g5f4  14. g3f4  14... c6e7 [%c_effect e7;square;e7;type;Mistake;persistent;true] After this mistake, White gains the initiative. 15. f3h4 [%c_effect h4;square;h4;type;GreatFind;persistent;true] 15... b7g2
