Well Immpy, your VH+ 101122 puzzle had me completely stumped, but I faired better with this one!

Remove <1> from r4c8 to solve

Code:

+------------+---------------+-----------------+
| 3  8  49   | 6    2    19  |  145   145   7  |
| 6  7  1    | 45   45   8   |  2     9     3  |
| 49 2  5    | 7    39   139 |  6     8     14 |
+------------+---------------+-----------------+
| 7  45 6    | 345  8    2   |  9    x1345 a14 |
| 89 3  89   | 1   c45   7   | b45    6     2  |
| 1  45 2    | 9    6   d34  |  7    z345   8  |
+------------+---------------+-----------------+
| 48 6  3478 | 2    37   5   |  1348  14    9  |
| 5  1  347  | 8    379  349 |  34    2     6  |
| 2  9  348  | 34   1    6   |  348   7     5  |
+------------+---------------+-----------------+

Play this puzzle online at the Daily Sudoku site

If x=1, a=4, b=5, c=4, d=3 leads to no <3> in box 6

or you could look at it as:

If x=1, z=3, d=4, c=5, b=4, a=1

Alternatively, there is a <45> W wing in r4c2 and r5c7 which removes the <4> from r4c89

My solution was the same as Tom's.

Code:
+--------------+--------------+----------------+
| 3   8   49   | 6    2   19  |  145  145  7   |
| 6   7   1    | 45   45  8   |  2    9    3   |
| 49  2   5    | 7    39  139 |  6    8    14  |
+--------------+--------------+----------------+
| 7  a45  6    | 345  8   2   |  9    1345 1-4 |
| 89  3   89   | 1    45  7   | d45   6    2   |
| 1  b45  2    | 9    6   34  |  7   c345  8   |
+--------------+--------------+----------------+
| 48  6   3478 | 2    37  5   |  1348 14   9   |
| 5   1   347  | 8    379 349 |  34   2    6   |
| 2   9   348  | 34   1   6   |  348  7    5   |
+--------------+--------------+----------------+

(4=5)r4c2 - r6c2 = r6c8 - (5=4)r5c7 => r4c9 <> 4; stte.
