Lesson #14: First question, what is a chain? Well, I like to think of it as a “what if” scenario. A remote pair is the result of a chain, and is one of a variety of chaining strategies in sudoku. This strategy can be used to eliminate candidates and usually helps to solve harder level puzzles.

Remote Pairs is one of my favorite advanced strategies and probably one of the easiest chains involving bivalue cells to spot. So nice to see you feature them. You mentioned that remote pairs have to contain at least 4 cells. You can clarify it a little further and say that it has to be an even number of cells in the chain (4,6,8,etc.).

Thanks Smart Hobbies, you are right, since they are pairs, they have to come in two's, so its always an even number of cells. One true, the other false. Thanks so much for the comment!

LOVE your videos! Thank you for what you teach us. (You must be a math teacher in "real life". 😊 I have pairs all over my "extreme" board, but most are not in the same house. Is there anything special about this?? I keep coming across this scenario. Thanks!!

I am new to your videos and WOW! You are very helpful and I am renewing my interest in sudoku. I didn't pick up if the route of the chain is arbitrary or is there a rule? Some seem obvious, but others have more than one possibility. Thanks

I’ve really enjoyed your instruction videos. I’ve not yet seen how to identify a matching pair. Also when do you recommend increasing the number of candidates to greater than 2 squares in a unit? Thanks,

@LearnSomethingNewEveryDay 11 ай бұрын

Hello Marv, thanks for your comment, I appreciate it! A matching pair is when there are only two of the same candidates in a unit, for example a 5,9 in two cells in a row, column or block. You might want to check out the Sudoku Guy, he has some great instructional videos and I have a video on hidden pairs here: kzfaq.info/get/bejne/eshig7yUvd-bmZ8.html I hope that helps! As for increasing the number of candidates I only do that at the beginning of solving the puzzle, but once you are "stuck" then you need to put in more candidates as logic dictates it. Thanks for your question!

Why are you purposely skipping F9 which is also a 3-4 matching pair to B9? I realize it resolves itself, and your trying to stay with a chain of four. But this makes it confusing when one is trying to learn to identify groups and pairs.

Thanks Rood67 for your comment and feedback! This is meant as a lesson on remote pairs so I'm giving examples, first with 4 cells, then with 6. Hopefully my examples help to explain the concept. There may be other examples and concepts to explore, thanks for pointing that out!
