				Yes, this was an easy VH. I found four different ways to solve it in one step.

				| UR (4,7)r89c48. We can remove 6 in r2c8 to avoid the DP in BOX 8 and 9. In this case 6 must be in r1c9 which solves the puzzle. |

				Here is the puzzle after removing most/all basics.
 
From here, you can see the UR (which I did not see when I solved this), and the 1-2-3 xy wing.
