Hello

Can anyone help me with this puzzle? I have removed 2 from D7 and E6 as it has to be in either F6 or F7.

749..12..1....4.8.8.2...4..6749.3.5.29.1....4.1..47....814....99.7.1..4.426.79...

I can get as far as here with a couple of reasonable chains and UR's.

Code: Select all
*----------------------------------------------*
| 7  4   9   | 3568 3568 1    | 2    36   356  |
| 1  356 35  | 2    3569 4    | 3569 8    7    |
| 8  356 2   | 7    3569 56   | 4    1369 15   |
|------------+----------------+----------------|
| 6  7   4   | 9    2    3    | 1    5    8    |
| 2  9   358 | 1    568  568  | 367  367  4    |
| 35 1   358 | 568  4    7    | 369  2369 236  |
|------------+----------------+----------------|
| 35 8   1   | 4    356  256  | 3567 2367 9    |
| 9  35  7   | 3568 1    2568 | 3568 4    2356 |
| 4  2   6   | 358  7    9    | 358  13   135  |
*----------------------------------------------*

From here on you will have to use forcing chains. This is a difficult puzzle for a general enquiry.
