This one has me stumped - another "diabolical" from a Sydney newspaper. I've added skyscrapers to my portfolio of techniques and even used one to get to this point. But now I'm stuck - do I have to learn yet another trick?

Code:

+----------+---------------+-------------+
| 5   8 3  | 2    146 46   | 7    9  16  |
| 2   7 16 | 89   3   89   | 4    16 5   |
| 4   9 16 | 5    16  7    | 8    2  3   |
+----------+---------------+-------------+
| 7   5 24 | 46   8   146  | 1269 3  69  |
| 8   1 29 | 3    69  5    | 26   4  7   |
| 3   6 49 | 7    2   149  | 19   5  8   |
+----------+---------------+-------------+
| 69  3 7  | 1    5   2    | 69   8  4   |
| 169 4 8  | 69   7   3    | 5    16 2   |
| 169 2 5  | 4689 469 4689 | 3    7  169 |
+----------+---------------+-------------+


All help gratefully received.

Take a look at 9 in R4 and B6.

Then, a UR and an XY-wing reduce it to a remote pair or a Bug+1.

I just knew that I was missing something obvious like a hidden pair or a box-line interaction. How annoying.

Many thanks Keith.
