I got it straight.I don’t know if there is a catch. 1.Rc7+ Kxe6 (1…..Nd7 2.Rxd7+ Kxe6 3.Bh3+ kf5 4.Rf7+ kg5 5.Rf5#) 2.Rh6+ Kf5 3.Rf7+ Kg5 4.Rg6+ Kh4 5.Rh7# In both cases 3…. Ke4 4.Rh4#
The critical line is 1.Rc7 Kd6. In that line, there is some careful play that white must do with his king to evade checks long enough to mate with the knight from f7.
