A problem which could be said to illustrate the value of persistence!
Solution: 1.Sf2 threatens 2.Sxg4, and Black can only defend by cutting the rook guard of d3 with 1...Bd2. The line-opening allows the a6 rook to renew the threat, and begins a sequence. 2.Ra3 (threat 3.Sxg4) Sc3 3.Ba6 (threat 4.Sxg4) S7b5 4.Qh7, and Black is in zugzwang. Any move will open a guard on d3 and the knight will finally get to mate on g4! If 2...Sxa3 3.Qxa3 mates next move, while if 3...Sa6 4.Qxa6 does likewise.
Jacob Hoover: This one was pretty easy, but a clever idea nonetheless.
