Boy, you sure do like grouped strong links!
| Code: | ***** ***** *****
-a =b -c =d -e =f => [r3c4]<>9
+-----------------------------------+
| . 9 9 | . . 9 | 9 c9 . |
| . . . | . . a9 | b9 . b9 |
| 9 . . | -9 . . | 9 c9 . |
|-----------+-----------+-----------|
| 9 9 . | . . e9 | 9 d9 9 |
| . . . | f9 . . | . . 9 |
| 9 9 . | f9 . . | . . 9 |
|-----------+-----------+-----------|
| . . 9 | . . . | 9 . 9 |
| 9 . 9 | . . . | 9 . . |
| . . . | . 9 . | . . . |

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
edit 2nd try...

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

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. |
