Nice find Ted. I was looking and missed it.
I played a couple of X-Wings on 1, an apparently worthless Type 4 UR on 24 and an AIC; r2c6<>6. |

Ted, do you mean an almost W-Wing? |

Danny,
I did not think of the pattern as an almost w-wing, but it definitely could be viewed that way. My POV was simply a group of (6s) which, in this case, could also be considered as a Kraken Row: (6)r2.
Terminology is $#*&^.............

I still need some help seeing this. I see the W wing if r2c6<>6, but not how the alternative of r2c6=6 leads to eliminations in r8 - seems to me it targets row 7 instead. Can someone please clarify?
Thanks |

Susme,
How about: (6)r2c6-r13c4=r9c4-(6=1)r9c8
Sometimes the obvious to the hardest to see......

You need to proceed past r7c6 in your logic:
| Code: | (6)r2c6 - r7c6 = r9c4 - (6=1)r9c8 => r8c79<>1
