Tiny little crimps on a balancy slab. Shorties have an extra crux hopping up on to the first foothold, so stacked pads may be needed to compensate for all the years of erosion at the base of the boulder.
For me the crux was getting off the ground, although even after the good hold there is a long reach to the left hand crimp. We used a slightly worse vertical crimp that was fractionally closer. For the fist move my beta involved pressing down with my right thumb on a marginal crozzle (see photo), and Beth used the tiny edge next to the crack.
Rain sucks, but broken holds suck even more. Remember, never climb on wet rock in Fontainebleau.
The sandstone becomes brittle, and pulling on it will ruin classic problems. Drying it doesn't help, because it's still wet and weak inside.
All you can do is wait for better conditions.
