| Hey Hugh, you missed the basic locked 5's in row 3 which eliminates the 5 from r1c9 and r2c8 leaving the one-step XY 496 (its pivot is actually in r1c9) which removes the 6 from r2c1. |

| I missed the locked 5s too. Nevertheless, it's fun to do a two-stepper on these puzzles. |

| The W Wing in 36 boxes 1 and 2 acting on 6 in row 1 give3s a solution without sorting out the 5s in box 3! |
