context: 1. d2d4  1... g8f6  2. b1c3 An interesting move to escape the normal queen's pawn lines. It's become popular even in elite grandmaster games, especially in blitz. 2... g7g6  3. e2e4  3... d7d5  4. e4e5  4... f6h5  5. f1e2 Other moves are also tempting. 5... h5g7 Theoretically this was the bishop's square, but perhaps Black's position is a little better than it seems, since the knight can go to f5 or e6, with some luck. 6. h2h4 I'm not sure this move helps White's position. 6... h7h5  7. c1g5  7... g7e6 It would be better to develop the c8-bishop first. 8. g5e3 This suddenly gives Black a lot of counterplay in the center. 8... c7c5  9. g1f3  9... c5d4  10. f3d4  10... b8c6  11. d1d2  11... e6d4  12. e3d4  12... e7e6 It's bad to shut the bishop out of the game. 13. e1c1  13... f8h6  14. f2f4  14... a7a6  15. g2g4 Opening the kingside. Black is unable to offer much resistance. 15... h5g4  16. e2g4  16... h6f8  17. h4h5  17... g6h5  18. g4h5  18... h8h7  19. d1g1 There are many winning moves. 19... d8c7  20. d2d3  20... h7g7  21. g1g7  21... f8g7
