1) 6 conjugate ALS-Wing
(6)e4=(138)ghi4 & (6)e6=(238)abc6 => i6,a4<>38
Also (6)e4=(4)e1 & (6)e6=(15)e79 => e1<>1 UP=53
2) 7 color wing(di1-ei6) UP=81

1. Note triple 145 at c578.Unique possibilities to 53.
2. If h3=7=d5;column e is devoid of 7.So h3=2.UP81.

21:01, easy but slow as I had a number of interruptions along the way.

I know spotting AURs is not a best practice, but after applying basic techniques to UP 53, I considered (79) at 3ei and 6ei to be an AUR. I eliminated (79) as candidates for 3i, and therefore could not find a solution. In fact, there is a 7 in 3i. Yet, just because this 7 sets up a UR, there are not two solutions to this puzzle. That makes me hesitate to ever look for AURs again.

Never mind my previous posting. I read the blog tip on AURs a little more carefully, and I realize that 3ei and 6ei would not form a UR
