There are one-stepper chains present, but I prefer this unproductive UR because I found it manually.
Code: | UR3 (14) [r47c23] => [r5c2]<>8, [r6c3]<>9

| 3 148 1489 | 6 59 2 | 45 189 7 |
| 89 24-8 6 | 7 359 1 | 2345 2389 58 |
| 5 127 17-9 | 4 39 8 | 23 1239 6 |

very nice!
I see it this way.
(8)r5c2 - (8=9)r5c1 - 14URr47c23[(9)r4c3 = (8)r4c23] - (8)r5c2; r5c2 <> 8
(9)r6c3 - (9=8)r5c1 - 14URr47c23[(8)r4c23 = (9)r4c3] - (9)r6c3; r6c3 <> 9

Started off as a good one for a cold Sunday morning. Found an x-wing on 6; an ER on 8 and a Type 2 UR - then got nowhere.
Once the chains have to come out - I'm outa here. |
