Not genius. What you're describing is the difference between a problem and a mystery. If you have some basic skills in a domain, when a problem arises, you usually have some idea about how to solve at least part of the problem. But if you have no skills, every part of even the most basic problem is a mystery that you have no idea how to begin to solve. Then when you see someone solve your mystery, especially if they can do it adroitly, to you they appear to be a genius. Mystery solved. On that basis, a genius is someone who can solve a problem that other experts had no idea how to solve. A supergenius is someone who solves a problem that other experts didn't realize even existed. (AKA, they hit a target others could not see).
