My solution is probably similar to Marty's.
Remote Pair 26,
ER on 2,
xy-wing 6-89,
skyscrapter on 6,
Either a Remote Pair on 26 with transport on 2 or a skyscraper on 2 with transport makes an identical deletion,
ER on 2 (another one),
coloring on 6 deletes a bunch to complete the puzzle.

I have a file of NR puzzles where single-digit turbot fish logic -- ER, Kite, Skyscraper, and finned/Sashimi X-Wing -- contributes significantly to the solution. This puzzle was from that file.
| Code: | b2 Naked Pair <> 26 r1c6,r2c56
c4 Naked Pair <> 26 r45678c4
r9 Naked Pair <> 26 r9c25
r5 Naked Quad <> 2369 r5c48
r39c4 Skyscraper <> 26 r2c1,r8c3 Remote Pair
r7 Naked Pair <> 69 r7c278
c2b7 Locked Pair <> 45 r8c2
r8 b9 Locked Candidate 1 <> 6 r8c256
r8 Naked Triple <> 239 r8c5
c1b7 Locked Candidate 1 <> 6 r56c1
|
| Code: | c39r4 Skyscraper (Sashimi X-Wing) <> 6 r2c2
r2 b3 Locked Candidate 2 <> 6 r1c7
c25\r15 finned X-Wing <> 6 r5c6
|
If you'd like, the second block can be shortened to:
| Code: | finned Kraken X-Wing c25\r15 w/fin r6c5 => r5c6<>6
Kraken: (6)r2c2 - r2c789 = r1c7 - r1c5 = r56c5 => r5c6<>6
+--------------------------------------------------------------+

| 8 @267 4 | 5 39 39 | 1267 1267 67 |
| 1 3 26 | 26 7 8 | 5 4 9 |
|--------------------+--------------------+--------------------|
| 4 1 26 | 379 8 5 | 2367 2679 67 |
| 239 *269 5 | 17 *2369 239-6 | 8 17 4 |
| 239 8 7 | 139 #2369 4 | 1236 1269 5 |
|--------------------+--------------------+--------------------|
| 69 45 3 | 8 1 69 | 47 57 2 |
| 7 29 8 | 39 45 239 | 46 56 1 |
| 26 45 1 | 26 45 7 | 9 8 3 |
+--------------------------------------------------------------+
# 69 eliminations remain
|
Bottom Line: Two good examples by Marty and Ted of working through the puzzle! |
