I’m very interested to see the solution to the painting puzzle. I tried out a bunch of different sealed-bid mechanisms and none seemed to work properly. All of them provided an advantage to shading from one player assuming the other played honestly. I was just trying them out in a table of outcomes, not trying to solve analytically as I don’t think I understand the math well enough to do so at the moment.
