A totally different three step sequence than Dan used but I deleted similar digits.
Quote:
Kraken x-wing 8 r26c18 with fin r7c1 deleted 8 r6c3, that opened a
x-wing 8 in r26c18 to delete the Kraken fin in the previous step in r7c1, that setup a
xy-wing 13-5 with pivot 13 in r9c3 and pseudo-cell 35 in r5c4. Transport 5 r5c4 => r5c6 => r2c6; delete 5 in r2c1.

Dan, I have a terrible time finding patterns such as your first step in this puzzle. Please provide some detail after others have posted their solutions.

Thanks, Ted

At this stage

Code:
+------------------------------------------------+
| 3   4   7    | 159   6    8  | 19     2  15    |
| 58  1   9    | 2     4   35 | 7     38 6     |
| 6   2   58   | 1359 *13   7  | 13489  14 13458 |
--------------------------------------------------
| 2   38  4    | 6     9    1  | 38     5  7     |
| 7   9   6    | 35    8    35 | 2      14 14    |
| 18  5  138  | 4     7    2  | 6     38 9     |
--------------------------------------------------
| 158 38  1358 | 7     2    6  | 134    9  134   |
| 9   7   2    | 13    5    4  | 138    6  138   |
| 4   6  *13   | 8    -13   9  | 5      7  2     |
+------------------------------------------------+

the two (13)s marked by asterisks in r3c5 and r9c3 are linked by the conjugate 3s in rows 2 and 6. So one of r3c5 and r9c3 must contain 1, which can be eliminated from r9c5.

Code:
+-----------------------------------+
|  3  4   7   | 9  6 8  | 1   2  5  |
| *58 1   9   | 2  4 35 | 7  *38 6  |
|  6  2   5-8 | 35 1 7  | 9   4  38 |
-------------------------------------
|  2  38  4   | 6  9 1  | 38  5  7  |
|  7  9   6   | 35 8 35 | 2   1  4  |
|  1  5  *38  | 4  7 2  | 6  *38 9  |
-------------------------------------
|  58 38  358 | 7  2 6  | 4   9  1  |
|  9  7   2   | 1  5 4  | 38  6  38 |
|  4  6   1   | 8  3 9  | 5   7  2  |
+-----------------------------------+

There is now a (finned) x-wing for 8 in rows 2 and 6, which eliminates 8 from r3c3.

Neat puzzle.

Thanks for the details, Dan. I still have great difficulty finding chain structures.

It is interesting that my first move, a Kraken x-wing on 8, used some of the same cells and deleted the identical 8 as your m-wing. I now also notice that my second move is unnecessary since my third move is a complement to your second move.
