				Let's see if we had the same ending.

				Marty,
 
 
That is how I solved it.

				Another unusual one step ending is a useless skyscraper on 6 in r29c2. However extending the pincer 6 in r9c4 to r1c6 via r8c6 does the trick.

				| Ted, just from a terminology standpoint, if you see the term "multi-coloring" in my posts, it's probably a skyscraper or kite with pincer extension. When I first learned multi-coloring it was defined as two coloring chains, weakly linked. Which is basically the same thing but I tend to use the language I was originally taught. |

Multi-coloring was not mentioned here until your post,  I am confused. |

Maybe "multi-coloring" was not mentioned in this thread, but a skyscraper is multi-coloring, and a skyscraper with pincer extension is also multi-coloring.
