				| Two steps: x-wing (1), xy-wing (269). Any one-step solutions?

 Not from me. I obviously missed something, or a lot of things, since it took me six steps. So I erased it, did it again and it took me seven!!

				| Actually, I used the x-wing(s) on <1> and an ER on <4> before finding the <269> xy-wing. So I started again and just used the xy-wing - and found that was all that was needed.   Seven steps indeed!! |  |

 After basics, I had this code:
  	  | Code: |  	  | *--------------------------------------------------*
 | 1    5    49   | 6    79   3    | 478  2    478  |
 | 8    49   6    | 5    79   2    | 347  1    347  |
 | 7    3    2    | 4    8    1    | 5    6    9    |
 |----------------+----------------+----------------|
 | 2    8    179  | 19   4    5    | 36   79   36   |
 | 4    69   5    | 3    26   7    | 1    89   28   |
 | 3    169  179  | 129  126  8    | 27   4    5    |
 |----------------+----------------+----------------|
 | 9    2    18   | 178  3    4    | 678  5    678  |
 | 5    14   3    | 78   12   6    | 9    78   24   |
 | 6    7    48   | 28   5    9    | 24   3    1    |
 *--------------------------------------------------*
 | 
 
 My solution was exactly like that posted by Earl. The x-wing <1> to eliminate <1> in r6c34 which opens up the xy-wing <269> with pivot <27> at r6c7 and pincers <79> at r4c8 and <29> at r6c4 to solve the puzzle.
 
 How did you eliminate the <1> in r6c4 or did you use a different xy-wing <269>?

 Well - there wasn't a <1> there after I rubbed out the first attempt and did it again.  The rubber (or eraser to you guys) must have slipped.

				| I solved it the same way everyone else did but didn't count the # of steps! I enjoyed today's puzzle more than other VHs recently because it didn't just fall apart like some do --  it took some methodical work. But not too much!

 I am puzzled with others saying that the xy wing was <269>. Can a <269> xy wing pivot on something with a 7 in it?
 
 I am thinking that the xy-wing should be <279>.

				| I thought that it was a fun puzzle.  We solved it with one x-wing and the 269 xy-wing.  For my husband and I, these puzzles have been fun lately.  Good practice too with the xy-wings. 
 There have been more VH puzzles than usual in the last week or so.

				| Aha! There is a 269 xy wing and a 279 xy wing. I never saw the 269 wing. Either solves the puzzle. |  |
