Ok, this one is very left field - apologies!

I have been trying to make use of guardian/broken wings recently with not very productive results - in some ways they are a bit like Ted's external SIS moves. The 4s here are clearly very turboty...

Code:
 *------------------------------------------------------------*
 | 2      1     *48   | *45   3     59    | 7     69    68    |
 | 5      9     3     | 8     6     7     | 2     1     4     |
 | *(4)78 78    6     | 1     (49)  2     | 58(9) 3     58    |
 |--------------------+-------------------+-------------------|
 | 9      2     1     | 3     5     4     | 6     78    78    |
 | 6      78    78    | 9     2     1     | 45    45    3     |
 | 3      4     5     | 7     8     6     | 1     2     9     |
 |--------------------+-------------------+-------------------|
 | 1      5     4789  | 6     479   3     | 48    478   2     |
 | *47    3     2     | *45   1     8     | &45-9 69    567   |
 | &478   6     4789  | 2     479   59    | 3     4578  1     |
 *------------------------------------------------------------*

The potential broken wing (terminology?) is marked with * and the guardians are marked with &. One or both of r9c1 and r8c7 must be 4.

(4)r8c7 ; r8c7<>9
||
(4)r9c1 - r3c1=(4-9)r3c5=r3c7 ; r8c7<>9

Or as an AIC...

BrokenWing(4)[(4)r8c7=(4)r9c1] -r3c1=(4-9)r3c5=r3c7 ; r8c7<>9
