Or 24-7 XYZ wing pivot r9c1: r2c6=7: stte (Easiest basics  for a long time...)

Sorry, Hugh, I don't see it. I don't see a 7 in r2c6. For there to be an elimination, there needs to be one or more cells that see all three of XYZ, XZ and YZ. Those cells would need to be r78c1. |

				| Marty - As always absolutely right. I was looking at r6c2 but the 247 arrangement doesn't affect that or anything else! |

				| I used the XY-Wing 27-3 pivoted in R5C9.  That appeared to get me to the end. |

That's very interesting, one cell being a pivot for two XY-WIngs. |
