This is an awesome problem on the B-1 Boulder, found just a couple feet to the left of the Slopster. It features some highly unconventional moves for a boulder problem and is an enjoyable puzzle to solve.
Start with a good undercling and sidepull at head height. Climb past the large right-facing block and top out to the right. The first couple moves are thuggish, but after that it takes more brains than brawn.
