Two black pieces place themselves on a single future pin-line. One of them is also a self-block and the other follows a checking unpin from White.

For a short time in the 1970s, following his article on Chinese Pieces in the British Chess Magazine, I corresponded with John Driver. This was the only problem that resulted. John had been working on a Grasshopper idea that he couldn’t get sound. I couldn’t get it sound either, but at some point realised that it might be easier with Chinese Pieces.
