this puzzle was solved relatively easily with a new approach (not a method or technique) that I use in very difficult Sudoku puzzles, but it does not work on all puzzles, however it did work on this one and on AI Escargot from 2006. Before using this approach, I "accidentally" solved it by looking for a cloaked X-Wing. If this post generates interest, then I would be happy to describe both incidents.
