Looking for unusual moves, I found one that I do not know how to describe or notate. It is like a skyscraper except the two pincers do not share a common level, but a simple transport provides a deletion.
| Code: |
*-----------------------------------------------------------------------------*
| 5 1 #26 | 239 8 239 | 7 4 #69 |
| 268 7 268 | 4 5 129 | 126 3 169 |
| 9 3 4 | 7 12 6 | 12 5 8 |
|-------------------------+-------------------------+-------------------------|
| 14 26 9 | 236 123467 12347 | 8 267 5 |
| 3 26 7 | 8 126 5 | 16 9 4 |
| 14 8 5 | 269 12467 12479 | 3 267 167 |
|-------------------------+-------------------------+-------------------------|
| 7 5 #36 | 1 #346 34 | 9 8 2 |
| 26 4 1 | 236 9 8 | 5 67 367 |
| 268 9 2368 | 5 2367 237 | 4 1 36 |
*-----------------------------------------------------------------------------* |
skyscraper-like on 6 in r17c3 marked #, plus transport: (6)r1c9 - r89c9 = (9)r8c8; r8c4<>6
Then two xy-wings complete the puzzle.
xy-wing 2-36 with vertex r8c1; r7c56<>3
flightless xy-wing 36-7 with vertex r9c9: (7)r8c8 - r46c8 = (8)r6c9; r6c5<>7
Does anyone have a suggestion how to describe my first move?

| Code: | finned Franken Swordfish r17b9\c39b8 w/fin r8c8 => r8c4<>6
|
As an X-Chain:
| Code: | [r7] [r1] [b9]
(6): r7c5 = r7c3 - r1c3 = r1c9 - r89c9 = r8c8 => r8c4<>6

Danny,
Thanks for the feedback. I have heard of Franken fish, but have never looked into the technique. Guess this is an occasion to do so.
As for the notation, my only excuse is jet-lag due to the 38 hours required to fly home. A nightmare trip!
