A perfectly constructed problem showing beautiful correspondence between the black and white play.
Solution: If White tries 1.Sd8?, threatening 2.Sf7 mate, Black’s
defence 1...Bd5 works because the white knight prevents the bishop from exploiting the obstruction of black’s knight (2.Bd8?). Similarly after 1.Bd8?, threatening 2.Bxf6 mate, 1...Sd5 works because White cannot play 2.Sd8? to exploit the fact that Black cannot play 2...Bd5. The key is
1.Rg6, threatening 2.Rxf6 and 3.Rf8 mate, and now White
can successfully meet the black self-obstructions with his set continuations: 1...Bd5 2.Bd8 and 1...Sd5 2.Sd8.
