Still looking for more unusual moves, I found another 'funny" xyz-wing 235 in r9c3.
(2)r9c3 - (2=3)r8c3; r7c23<>3,
(3)r9c3; r7c23<>3,
(5)r9c3 - (5=3)r9c6 - r9c79 = (3)r7c79; r7c23<>3.
Thus, r7c23<>3 to complete the puzzle.

I have recently found a small number of patterns similar to this one and was wondering if they have a name?

It appears to me that you took a non-productive XYZ-Wing and extended/transported the pincer at r9c6 to r7c79. As such, I don't think it has a name.

You mean an absolutely wonderful finned xy-wing? Yes I saw it and left a post.

I didn't look at the grid and that particular move, but what you have described was described here a couple of years ago and it was called "XYZ Transport." It's fun but I've only been able to use it a couple of times.
