This video and the kite string video really helped me to master the various links. Now that I have binged many of your videos and seen both at the same time, I can see how I became so confused. With X-Wing, and related techniques, I only needed 1 candidate per cell. With this, I need 2. Thank you so much.
The Turbot Fish, 2-String Kite, Empty Rectangle, Skyscraper are all variants of the X-Chain. So when solving a puzzle I look for X-Chains before I look for Empty Rectangles and Turbot Fish. I still look for Skyscrapers and 2-String kites directly since those patterns are easier to spot than running my finger over the puzzle as I follow the X-Chain.
Around the 4th minute mark we missed one of the kill zones with the puzzle. The kill zone is just one cell 9, 4. This cell shares two houses with cell 7, 5 and cell 9, 9. It turns out cells making up the kill zone share the same two color assignments. So there are no non-possible candidates in cell 9, 4. So nothing is missed. We will probably make a revision to this video at some point in the future.
[Edit: never mind; it seems that you figured it out in a later video] You can specify exact times in the video like this: 4:09. UA-cam then turns it into a link to start the video at that spot in the video. You can have an entire table of contents in your description or comment. The description is better, I think.
I just watched this video because it was required to understand the XY chain video. This remote pair technique is very nifty. Is it a special case of the XY chain?
I just found another error in the video. At the 6:28 mark the video says, "the non-possible candidate is removed" but the possible 9 candidate in cell R2C5 remains. It should be removed from the cell.

Yes. With the Remote Pair all the cells have the same two X and Y values.
