After beating my head against the wall working on XY_01 Puzzle 11, this puzzle was a delight. I found two finned x-wings, two x-wing and an ER, but then I found a move that solved the puzzle in one step:
Quote:
w-wing<28> at r4c9 & r5c6 with a grouped strong link in box4. It then takes some clean-up but it is a one step solution.
