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 |

| 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
