Hi Ruud,
My recent solving experience has suggested that the pattern I call semi-remote naked pair (first reported (AFAIK) by John MacLeod and called the corkscrew rule, then posted by Stephen as an example of a y-wing style, and others have called it a w-wing) is a terribly useful and common pattern. In theory, it will get picked up as a Medusa Bridge, I think, but in practice, they are rarely caught by SudoCue. Any chance on adding this to a future release?
