I took the longer route with a boulder in the path.

ALS A 138 r7c35
ALS B 178 r8c56
Exclusive: 1
Common: 8
r8c3<>8,

(8=7)r3c9 - (7=3)r2c7 - r2c5 = r7c5 - (3=8)r7c3; r7c9<>8,

Still another interesting (and maybe invalid) pattern.
Code:
 *--------------------------------------------------*
 | 1    38   378  | 9    4    357  | 357  2    6    |
 | 9    6    5    | 8    37   2    | 37   1    4    |
 | 4    2    37   | 1    6    357  | 357  9    8    |
 |----------------+----------------+----------------|
 | 3    4    2    | 7    5    6    | 9    8    1    |
 | 5    9    6    | 3    8    1    | 4    7    2    |
 | 8    7    1    | 2    9    4    | 6    3    5    |
 |----------------+----------------+----------------|
 | 2    5    38   | 6    13   9    | 18   4    7    |
 | 6    18   9    | 4    17   78   | 2    5    3    |
 | 7    138  4    | 5    2    38   | 18   6    9    |
 *--------------------------------------------------*

Note the pattern in r13c367. Now view it as a (35), (37), (57) configuration (which I think is termed a BUG lite).
Looking at the outside row implications to prevent the deadly pattern, we find:
3: r1c2
5: None
7: None
Thus, r1c2=3 to complete the puzzle.

As always, comments are appreciated.

I believe in Ted! ...but since you invited comments, I'll be the kibitzer.

I think your pattern is valid, but you're making it slightly more difficult than need be. Your pattern is a classic type 1 MUG.

How can you tell? A MUG is a composite of two or more overlapping BUG-Lites. Here they are:
Code:
37 35 57
37 57 35

Together you get
Code:
37 357 357
37 357 357

It's a permutation of this archetype:
Code:
357 357 357
357 357 357

Simple as that, the only thing preventing the MUG is (8)r1c3, so it can be placed.

Another cool find Cool ...you're on fire this week.

Thanks for the feedback Luke. My understanding of URs, BUGs, Bug-Lites, MUGs , DPs, etc is still a fog. I truely need to read/understand the thread by Myth.

In the meantime, I appreciate support by those that already have insight into this world.

I'm far from the best source for insight, be warned. On the subject of advanced deadly patterns, get corroboration on anything I claim. I'm still learning this stuff myself, and there is a lot of confusion to go around.

BTW, have you forgotten that Myth Jellies cross posted his MUG paper here at Daily?

Compare your MUG above to this one you discussed earlier with Ravel and Danny.

Here's another from Norm.

Captain Pete pointed out this one, which is as close to the archetype as you'll see (rows 78.)
