Harder for me than the last two. But its quite interesting, there are different options to solve it.
Who likes (finned) swordfish and Sue de Coq, can try to find JSudoku's solution:
1 Swordfish
1 Remote Pairs
1 Skyscrapers
1 XYZ-Wings
1 Hidden Unique Rectangle
2 Finned Swordfish
1 Sue de Coq up to 6 cells
A hint to get started: Look at the 4's |

| I can't even add anything to the posted grid. The only basic step I see is from the naked 7's in C9 - which doesn't do anything. Certainly can't see any skyscrapers or xyz-wings. Did I miss something obvious? |

cgordon,
did you see the hint, i added later ? You can make it visible by highlighting (marking with the mouse) the "invisible" text right of the hint.
To make it more concrete:
Three of the 4's, all conjugated to the same one. can be eliminated with (multi)coloring, 3 strong links (skyscraper/kite plus transport) or finned swordfish.
Highlight the text above to make it visible. |

My path was 4 steps:
Finned Swordfish
Swordfish
XYZ Wing with transported pincer
W-Wing |

Do you (and others) look for swordfish, finned or otherwise, manually or with electronic assistance? I don't bother anymore it's so tedious. |

Manually i look for them at most if i cant find anything else (just before medusa), for the same reason.
When looking for nice puzzles, i usually ask a program to see, if it might be interesting (this filters many out quickly). And at least the older programs have ranked swordfish before techniques, which are much more familiar and preferable to me. (But its different, if you do it on paper or can highlight single numbers. With this option you are much faster.)
What i noticed is, that puzzles with a very symmetric pattern (like the diagonal pattern) often have swordfishs as the first good step (not so surprising, because the pattern offers more possibilities for a swordfish). |

Since most Swordfish contain at least one conjugate pair, I don't find them that difficult to spot manually while exploring conjugate links for possible Skyscrapers, Kites, ERs, etc. (A "fully occupied" 9-cell Swordfish is more difficult because of the lack of a conjugate pair.) It is Jellyfish that I find tedious to spot and only look for when almost all other approaches have been exhausted. (After a Jellyfish hunt, comes Sue de Coq, perhaps, then it is off to Medusa.) A simple, quickly jotted dot grid helps with spotting candidate patterns.
Norm,
I, for one, appreciate the "hidden font" spoilers. Often, when an overt solution is posted immediately, I skip the puzzle. |

This is my solution and JSudoku's Sue de Coq:
Coloring in 4 (skyscraper plus transport) and 2 kites for 6 bring you
here:
| Code: | *------------------------------------------------*
| 9 67 1 | 2 58 67 | 58 3 4 |
| 8 3 67 |@15 156 4 | 2 9 1-57 |
| 5 2 4 | 189 3 179 | 18 6 178 |
|--------------+------------------+--------------|
| 7 #59 3 | 6 4 2 |#589 1 *58 |
| 2 #159 8 | 3 7 *15 |#569 4 *56 |
| 16 4 56 | 1589 1589 159 | 7 2 3 |
|--------------+------------------+--------------|
| 3 8 2 | 4 @156 156 | 16 7 9 |
| 4 16 9 | 7 2 8 | 3 5 16 |
| 16 57 57 | 19 169 3 | 4 8 2 |
*------------------------------------------------* |
To destroy the DP 59 in rows 4/5 one of the starred cells must be 5.
The 5 in r5c6 can be transported to r7c5 and r2c4 (i.e. if r5c6=5 then
also r2c4=5).
This takes out the 5 in r2c9.
(Similarily you can take the 2 outstanding 5's in columns 2 and 7 and
transport r9c2=5 to r6c3, r5c6 and r7c5 to take out 5 from r1c5)
A skyscraper in 1 finishes it off.
In the same grid there is JSudoku's Sue de Coq.
(I never look for them, too hard to find for me, but interesting to see them.)
| Code: | *------------------------------------------------*
| 9 67 1 | 2 #58 67 | 58 3 4 |
| 8 3 67 |*15 1-56 4 | 2 9 157 |
| 5 2 4 |*189 3 179 | 18 6 178 |
|--------------+------------------+--------------|
| 7 59 3 | 6 4 2 | 589 1 58 |
| 2 159 8 | 3 7 15 | 569 4 56 |
| 16 4 56 |-158-9 1589 159 | 7 2 3 |
|--------------+------------------+--------------|
| 3 8 2 | 4 156 156 | 16 7 9 |
| 4 16 9 | 7 2 8 | 3 5 16 |
| 16 57 57 |#19 169 3 | 4 8 2 |
*------------------------------------------------* |
In r23c4 1589 cannot be 5 and 8 because of the 58 in r1c5 in box 2. So they form a 19 pair with r9c4 in column 4. And they cant be 1 and 9, so form a 58 pair in box 2 with r1c5.
Note, that Sue de Coq's can be much more complicated (i remember samples by Asellus). |
