| for 1-steppers, there are two versions of 369 xy wings. There are a couple of unproductive xy wings (for me ) as well an unproductive type 1 ur. With all those bivalue cells floating around there may be some w-wing action as well. |

Play this puzzle online at the Daily Sudoku site
Same solution, but the 'red herring' XY wing and UR do lead to an out.
Couldn't find a W wing though.... |
