In the left part of the wall, up a corner and right via 2 BH to a blunt edge to the 3rd BH. Along the edge via 3 BH (at 5th BH from the right), higher up left over an overhang and further up the wall (5 BH) to the 12th BH. (Due to rope drag, it is common to start via the Cunning Plan route, where from the 2nd K one traverses left to the blunt edge to the 3rd BH of the original route.)
