Interseting puzzle, which can be unlocked with only one advanced move. After simple steps and a sashimi X-Wing (skyscraper) we get:
Code: | +-------------------+-------------------+-------------------+
| 368 5 1 | 2 *369 7 | *89 4 3689 |
| 9 36 27 | 8 *36 4 | 27 1 5 |
| 3678 2346 2478 | 1 5 369 | 2789 378 3689 |
+-------------------+-------------------+-------------------+
| 2 7 9 | 34 *368 368 | 4-8 5 1 |
| 5 1 3 | 49 7 89 | 6 2 48 |
| 4 8 6 | 5 2 1 | 3 9 7 |
+-------------------+-------------------+-------------------+
| 3678 2346 2478 | 39 1 389 | 5 378 3489 |
| 1 34 478 | 6 3489 5 | 4789 378 2 |
| 38 9 5 | 7 348 2 | 1 6 348 |
+-------------------+-------------------+-------------------+
ALS-XZ: (8=9)r1c7-(9=368)r124c5 -> r4c7 <> 8 = 4
The rest are singles only. |
This ALS-XZ only involves 4 cells. So it's not really harder to spot than a Sue de Coq with 4 cells. _________________ Jean-Christophe

Nice find Jean-Christophe !
I got to the same place as you (doing it on paper) and found a finned swordfish, a different ALS and then two xy-wings.
Your method was sitting there through each of my steps!

JSudoku generated. I am having great fun with this!
Bonus puzzle. This one needs W-wing/ M-wing/ 2 ALS patterns, where "/" means "or".
Sashimi sword, 2 skyscrapers, maybe the x-wing and one of the above.
Code: | . . 5|. . 9|. . 3
. . .|7 3 .|. . .
3 . 8|. 2 .|. . .
-----+-----+-----
. 8 .|6 . .|. . 2
. 9 4|. . .|6 5 .
2 . .|. . 8|. 7 .
-----+-----+-----
. . .|. 7 .|3 . 1
. . .|. 8 4|. . .
4 . .|9 . .|7 . . |
Here is an example of an M-wing, close to a W-wing and xy-wing in terms of spotting the pattern. The cells marked "*" are strongly linked on 1. The cells marked "@" are strongly linked on 2.
Code: | +-------------------------------------+
| . *12 . | -2 . . | . . . |
| . . . | . . . | . . . |
| . . . | . . . | . . . |
|-------------+-----------+-----------|
| . *13 . | . . . | . . . |
|*12@ . . | 26@ . . | . . . |
| . . . | . . . | . . . |
|-------------+-----------+-----------|
| . . . | . . . | . . . |

Incredibly easy puzzle. W-wing by-passes 3 sashimi swordfish and a jellyfish.
Only hard technique is W-wing/semi-remote pair/y-wing styles.
There is an nearly worthless W-wing also available.
Use the one with 3 eliminations, not one.

Thanks for the excercise. Even though I am still looking for all of them I have learned a lot.
