Older version:

Yesterday I already found an example with the same shape, also rated 2.9 with the newest version and 3.2 (x-wing) with the one of october.

I solved it by hand and found a naked quad, resulting in a hidden pair and finally the x-wing, which reduced the puzzle to pointing/claiming and naked/hidden subsets(max triple).

So in the search of examples replacing generalized intersection by x-wing, I found the example above which replaced 2 generalized intersections, the first by x-wing and the second by generalized x-wing.

Is there a way to generate similar examples?

One possible solution is probably extending the fiendish rating(2.6 to 6.0) to 6.5 including generalized x-wings?
