My early hint, coming not too far from the International Date Line:

After unusually fruitful basics,
xy wing within the first two boxes

Yes- after a long wait for a VH found the same humdrum solution. Looking
for more interest could only find a type 1 UR leading to another
XY Wing using the same numbers. Maybe someone can find something
like a finned sashimi X wing (whatever that is....maybe I'm getting
sudoku mixed up with Star Wars....) Smile

Hugh, if you're really interested in Sashimi, I just played one the other day. I call it a Sashimi X-Wing, don't know about the finned version.

Code:
+-------------+---------------+---------------+
| 578 3579 2  | 37   6    4   | 3579 3578 1   |
| 178 1379 6  | 5    137  2   | 379  4    378 |
| 157 4    37 | 8    9    137 | 2    357  6   |
+-------------+---------------+---------------+
| 9   8    5  | 137  137  6   | 4    237  237 |
| 6   37   37 | 4    2    5   | 1    89   89  |
| 4   2    1  | 9    8    37  | 37   6    5   |
+-------------+---------------+---------------+
| 2   57   9  | 6    357  8   | 357  1    4   |
| 157 6    4  | 1237 1357 9   | 8    2357 237 |
| 3   157  8  | 127  4    17  | 6    2579 279 |
+-------------+---------------+---------------+


Note the 1s in r38. Almost a Skyscraper, but not quite. Since both r3c1 and r8c1 can't both be 1s, then either r3c6 or one of r8c34 must be=1. Under either scenario r9c6 cannot be=1 and gets zapped.

Now I really don't know if you wanted me to post that, but there it is. Laughing
