A simple and good move. Without the h6-pawn, Black cannot defend the position. White only has to stack the pieces up against the black king.
1. e2e4  1... e7e6  2. d2d3 The King's Indian Attack is always an interesting option in a blitz game. 2... d7d5  3. b1d2  3... c7c5  4. g1f3  4... b8c6  5. g2g3  5... g8f6  6. f1g2  6... f8e7  7. e1g1  7... e8g8  8. f1e1  8... b7b5 This is the main variation of the King's Indian Attack and the play is very characteristic, with well-defined plans for both sides after the center is closed with e4-e5. 9. e4e5  9... f6d7  10. d2f1  10... a7a5  11. h2h4  11... h7h6 I don't really like this move, as I prefer to wait for White to play h4-h5. Perhaps the intention was to prevent Bc1-g5, but that's not so dangerous. 12. f1h2  12... f8e8 [%c_effect e8;square;e8;type;GreatFind;persistent;true] A prophylactic and thematic move, the idea of which is to bring the bishop to f8, securing the h6-pawn against possible sacrifices. 13. h2g4  13... e7f8  14. c2c4 [%c_effect c4;square;c4;type;Interesting;persistent;true] This is a new move. 14... b5c4  15. d3c4  15... d7b6 [%c_effect b6;square;b6;type;Mistake;persistent;true] A fatal mistake. The knight was needed on d7 to defend the f6-square. 16. c1h6 [%c_effect h6;square;h6;type;GreatFind;persistent;true] The sacrifice on h6 appears anyway, even with Black's bishop on f8. 16... d5c4
