Haven't done this one yet, so going by the guidebook description. This is also known as The Pinch Problem.
Start with your left hand on a small, left-facing, lieback hold, which is nearly 6' above the ground and 5' right of the obtuse arete at the left end. Your right hand goes on a crimp to the right. The first move is to place the right hand on the pinch hold at the short and very rightmost vertical seam. Take the direct line to the lowest top-out without using the sloping shelf to the left.
