Something is wrong here, you have the white rook on a1 and king on b1 yet in your solution: 1)Nxe7,Qxe7 2)Rxf7,Kxf7 3)Qd5+,Qe6 4)Rf1+ This rook moves to F1 despite being blocked by the king on b1, maybe it should be on f1 at the start ? or the king and rook positions reversed. UltraB ,Rxf6!!,Kxf6,Qd4+,Ke7,Bg5+,Kf7,Bc4,Re8,Qf6+,Kg8,Bh6!
