Boy, you sure do like grouped strong links!

Code:
 *****   *****   *****
 -a =b   -c =d   -e =f   =>  [r3c4]<>9

 |  .  9  9  |  .  .  9  |  9 c9  .  |

Danny,

I don't quite understand your diagram, but my grouped kite may be simpler:
Code:

+----------------+----------------+----------------+
| 4    179  179  | 8    6    129  | 1259 579A 3    |
| 2    5    3    | 7    4    19b  | 189B 6    189B |
| 179  8    6    | 59   25   3    | 129  79A  4    |
+----------------+----------------+----------------+
| 1679 179  4    | 2    58   8-9  | 1369 39a  1569 |
| 3    2    5    | 69   1    4    | 7    8    69   |
| 169  19   8    | 569  3    7    | 4    2    1569 |
+----------------+----------------+----------------+
| 5    3    79   | 4    278  28   | 689  1    689  |
| 179  6    179  | 3    78   5    | 89   4    2    |
| 8    4    2    | 1    9    6    | 35   35   7    |
+----------------+----------------+----------------+


In B3: One of the groups A or B is not true (is not <9>). Then, one of the cells a or b is true, taking out <9> in R4C6.

Here is an example of a beginner over his head in nice loops:
Code:

 *-----------------------------------------------------------*
 | 4     179   179   | 8     6     129   | 1259  579   3     |
 | 2     5     3     | 7     4     19    | 189   6     189   |
 | 179   8     6     | 59    25    3     | 129   79    4     |
 |-------------------+-------------------+-------------------|
 | 1679  179   4     | 2     58    89    | 1369  39    1569  |
 | 3     2     5     | 69    1     4     | 7     8     69    |
 | 169   19    8     | 569   3     7     | 4     2     1569  |
 |-------------------+-------------------+-------------------|
 | 5     3     79    | 4     278   28    | 689   1     689   |
 | 179   6     179   | 3     78    5     | 89    4     2     |
 | 8     4     2     | 1     9     6     | 35    35    7     |
 *-----------------------------------------------------------*
r1c6=2=r3c5=5=r3c4-9-r3c8=7=r1c8=5=r1c7=2=r1c6=>r1c6=2

Keith: Your grouped kite is much simpler than my example. I was rushed and fixated on [r3c4]<>9. I suspect that there's a much simpler way to perform my elimination as well. Nice catch!!!

A valiant try, but I couldn't follow your chain. It broke down for me at

r1c6=2=r3c5=5=r3c4-9-r3c8=7=r1c8=5=r1c7=2=r1c6=>r1c6=2

Maybe you could write it out at as a sequence of individual statements.

if r3c4=5, r3c8=9, r1c8<>5, r1c7<>2, r1c6=2 oops it is r1c7=2
if r3c4=9, r3c8=7, well woe is me. Thanks Danny I will keep on trying.
