We haven't had one this tough in a long while!
I don't use UR's for puzzles here ever since Marty told me that they were not one of the 3 necessary VH moves in order to solve VH puzzles from this site so instead I used the X Wing of 6's followed by an X Wing of 3's followed by a 23-9 XY Wing in order to solve it. But it still took me 3 VH moves! |
