Hugh, there's a problem in the subject line because Jan. 24 is not a VH. I would've edited it but I don't know what puzzle it is.

It's an archive from 6th Jan 2011. Must have been left on when I came
to look at the computer yesterday. I thought it was strange that no one
had posted......!

Ill be getting a rep for doing this - I'll be more careful in future. Sorry to
all.

Hugh I hate to be so negative, but I don't see that solution. The wing is 39-29-23, with pincer of 2 and there are no direct eliminations.

It was an even more dozy day than I thought. After basics it should have been
this:

Code:

+-------------+----------+-------------+
| 23  8   9   | 23 1  5  | 6   4   7   |
| 7   4   16  | 23 69 8  | 39  5   12  |
| 235 356 156 | 7  4  69 | 389 29  128 |
+-------------+----------+-------------+
| 1   2   68  | 5  78 4  | 89  679 3   |
| 4   56  3   | 9  78 1  | 2   67  568 |
| 9   7   58  | 6  23 23 | 4   1   58  |
+-------------+----------+-------------+
| 35  359 4   | 8  39 7  | 1   26  26  |
| 8   1   7   | 4  26 26 | 5   3   9   |
| 6   39  2   | 1  5  39 | 7   8   4   |
+-------------+----------+-------------+


(With the same solution as Parkash 2 years ago!)

With further apologies

Hugh
