S-wingish off of overlapping URs (MUG)
Code:
 *--------------------------------------------------*
 | 26   7    14   | 14   28   3    | 69   89   5    |
 | 9    48   5    | 7    48   6    | 2    3    1    |
 | 26   18   3    | 9    5    12   | 67   478  478  |
 |----------------+----------------+----------------|
 | 3    5    8    | 2    1    9    | 4    67   67   |
 | 1    9    7    | 8    6    4    | 5    2    3    |
 | 4    6    2    | 3    7    5    | 8    1    9    |
 |----------------+----------------+----------------|
 | 5    2   -14   | 14   9    7    | 3    68   68   |
 | 7   *34+1  6   | 5   *234  8    | 19   49  *24   |
 | 8   *34+1  9   | 6   *234  12   | 17   5   *24+7 |
 *--------------------------------------------------*

(1)r89c2=(7)r9c9-(7=1)r9c7-r9c6=(1)r7c4 ==>r7c3<>1

Beautiful! Very Happy

Here is another (less classy) solution.
Code:
 *--------------------------------------------------*
 | 26   7    14   | 14   28   3    | 69   89   5    |
 | 9    48   5    | 7    48   6    | 2    3    1    |
 |b26   18   3    | 9    5   a12   |c67   478  478  |
 |----------------+----------------+----------------|
 | 3    5    8    | 2    1    9    | 4    67   67   |
 | 1    9    7    | 8    6    4    | 5    2    3    |
 | 4    6    2    | 3    7    5    | 8    1    9    |
 |----------------+----------------+----------------|
 | 5    2    14   | 14   9    7    | 3    68   68   |
 | 7    134  6    | 5    234  8    | 19   49   24   |
 | 8    134  9    | 6    234  2-1  |d17   5    247  |
 *--------------------------------------------------*
xy-chain
(1=2)r3c6-(2=6)r3c1-(6=7)r3c7-(7=1)r9c7 => -1r9c6; stte

if r3c6 is not a 1 then r9c7 is a 1

I also used an XY-Chain with r1c5=8--->r9c6=2; r3c6<>2.
