Remote Pairs Sudoku Chain Strategy

Показать описание
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.).

I've been able to solve very hard sudoku puzzles for several months now using a variety of techniques. But I find myself having to guess very hard ones using patterns I've noticed over this time. These are not as satisfying since I am guessing. But your videos have been really helpful to reasoning out some of these patterns. Thank you!

I enjoy your videos and you are now one of my favourites. In the example at 8:22, there is a 1/6 chain that is 6 pairs long. Start in C5 and finish at H1, eliminating 1 & 6 from H5. Cheers

Thanks for the videos! I was struggling to understand some solving technics until I watched your videos. Now I am stuck again on this 'Remote Pair':) My question is that does 'W-Wing' cover 'Remote Pair'? That is, if I already tried W-Wing, will it be true that I will not be able to eliminate anything using Remote Pair?

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

she mentioned it need to be more than 4 pairs. Does this mean it works with odd numbered pairs over 4 or just even? If it was with 5 pairs, wouldn't the beginning and end always have the same number?

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,

There is also a 4-8 chain in the last example similar to the one in the 4th example.

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!!

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.
