A problem which might be solved by looking for what John Beasley called the "Wouldn't it be nice if" move.
1.Sg5 threat 2.Bxb6+ Kxb6 3.Qc5+ Kc7 4.Se6
1…Sxg5 2.Qf2 threat 3.Bxb6; 2…Bxc5 3.Qxc5+ b6 4.Qe7
1…fxg5 2.Qc4 threat 3.Rxa6+ bxa6 4.Qf7; 2…Bxc5 3.Qxc5+ b6 4.Qe7
1…Rxg5 2.Rxa6+ bxa6 3.Qxh7+ Rg7 4.Qxg7; 2…Kxa6 3.Qc4+ Ka7 4.Qa4; 3…Ka5 4.Qa4 or Bb4.
A triple sacrifice key which is perhaps not too difficult to spot given the strong move 1...Rxc5 in the diagram.
