RE: Chess problem 47 / Schachaufgabe 47

Solution - the only one. :)

Here now the only solution, found by @greatwolf:

1. Qxg7+! Kxg7
2. f6+ Kh7
3. b6! cxb6 (3. ... axb6 4. c6! with the same idea like in the main variation.)
4. a6! bxa6
5. c6 Qg4! (That's the only way to get some counterplay.)
6. hxg4 h3
7. c7 h2
8. c8Q h1Q
9. Qf8! (Now it's over because of the threat Qg7#.) Qe1+
10. Kd8 Qd2+
11. Kc8 Qc3+
12. Kb8 ...
    
    And now black has no reasonable check anymore:
    12 . ... Qc8+
13. Kxc8 a5
14. Qg7#

Very nice chess problem which combines several ideas, like restricting the mobility of the opponent's pieces by means of a brilliant queen sacrifice, and a pawn break through with underpromotion into a new queen.
