A problem by a famous Danish composer which shows a thematic link
between the defences and the mating moves.
After the key, 1.Qg7, threatening 2.Qxf7+ Qd5
3.Qxd5, the black pawn at c7 can defend four times, leading
to four mating moves by the white pawn at c2. 1...cxb6
2.Scxb6+ Kb5 3.c4; 1...c5 2.Sxb2+ Bxb2 3.cxb3; 1...c6 2.Qxg4+
Sxg4 3.cxd3 (dual after 2...Se4), and 1...cxd6 2.Sxd6+
Kd4 3.c3. A beautifully constructed task. There is one
by-play variation 1...Qd5 2.Bxd5+ Kd4 3.c3.
Jacob Hoover: A true delight of a problem.
