"Well, I'm standin' on a corner
in Winslow, Arizona,
such a fine sight to see ..."

"...It's a girl, my Lord, in a flat-bed Ford, slowin' down to take a look at me ..."
Take it, Dan ...

It looks like a nice place to visit. I like the landscaping.

Judy, I think you have caught what Dan has........

Oh no!! Cathy too!

5:34 Maen! Nice train station... and that was a Hard, not a Tough. UP to 81!

"Take it eaaaaaasy, take it eaaaaaaaasy..." :)

"C'mon baaaaaaby, don't say maaaaaaybe, I wanna know if your sweet love is gonna saaaaaave me!"

37:27 - slow finding key to solving this one

"We may lose and we may win though we will never be here again"

1. After a2=7,d2=5,d7=6,locked 1s at c13,g7=1,pairs 12 at i12;69 at b13,h2=4 and Unique possibilities to 39.
2. Note triple 689 at beg3.If b2=8,this would create an unresolvable loop of pairs of 12 at c13,f23 and i12.Hence b2=2 and UPs to 81.

Hark, I think I hear a cry of the Eagles.

10:01, hi all.

Almost identical to Alfred's:
August 1 .au
1) Start 23 UP 26
2) (LC1) a89 => c789<>1 UP 27
3) (HP12)i12 => I12<>48, h12<>2 UP 29
4ab) (LC6)bg13 => b56g6<>6 UP 39
5) (UL12) c13,f123,i12 => (2)c7, directly, using hidden sets (12) as (1) is locked More...

Above, I should have written ... of (12), only (2) is not locked at c13 => (2)c7.
This puzzle is ripe with many uniqueness loops, AUR's etc. It would be a good study of these techniques for anyone who would be interested in them.

Hi Steve.I didn't see any AURs in this puzzle,but I remembered the idea of the unique loop (or unresolvable loop) from one of your blogs or posts.Regards,Alfred.

A longer path:
1)Start at 23,basic techniques to UP=39
2)(8):i6=b6-b2=c1-c7=h7,=>h5i8<>8.UP=40
3)(9)i8=(9-7)i4=h4-(7=2)d6-(2=9)d5,=>d8& lt;>9
4)(7):d6=g6-i4=i8,=>d8<>7.UP=81

28:44

better yet UR(69)fh45 =>(7)f4=(5)h5
2.sotir(8):i6=b6-b2=c1-c7=h7,=>h5i8<>8.UP=40
3.(7=5)g6-(5)h5=(7)f4-(7)d6 =(7)g6 => g6=7 UP=81.
