 More or less the same as Bud.SSTS to UP251) (7)e4=f5-(7=3)e3-f789=e7 => e4<>3; UP81 13/Jul/13 12:49 AM |  |
 This 8.2 reminds me of kobold's remark that SE 8.2s could usually be knocked off with a simple group chain or kraken, while a lowly 7.2 might take persistent chipping away over several steps until it yields. 13/Jul/13 1:13 AM |  |
 Hi Jim. you may be right. I think that this is the easiest 8.2 I've ever seen. 13/Jul/13 1:25 AM |  |
 Bud, I don't understand these: (7=3)f3-e3=(7)e4, and (3)f3-f78=(3)e7 . Are this meant to represent AICs? 13/Jul/13 2:31 AM |  |

 Jim, like an xy-wing, an S-wing has a pivot bi-value cell. In this case (37)f3. To complete the S-Wing you need a (3)=(-3)=(3)chain and a (7)=(-7)=(7)chain and these must both end in the same house. The advantage of using 2 chains, is that frequently you can expand one or both chains and get additional cell eliminations. 13/Jul/13 9:53 AM |  |
 Bud, Yes, understood, but your inferences are all confused. 13/Jul/13 1:16 PM |  |
