Remote pairs, a particular case of XY chain

I invite you to talk in this site about „Remote pairs, a particular case of XY chain”, my essay from page forum has been the only one in which I contrive to attach my essay as a word document, in initial form. Also, Andrew Stuart, the godfather of Remote pairs technique, has been so kind to place this essay on
and web sites. You will find a series of exciting exercises, which are waiting for response.
My study needs as well some observations and addings. Bob Hanson has sent me a pertinent alternative method to resolve the grid from Figure 3 with Forcing chain algorithm.
Good luck!

For me remote pairs are a special case of strong links, where you have the same strong links for a pair of digits. Therefore they are very easy to spot.
