Remote Pairs Sudoku Chain Strategy

[@tjbuege]

You have a gift for teaching! Your Sudoku tutorials are the easiest to follow of all I’ve found so far on KZbin. Thank you!

[@SmartHobbies]

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.).

[@LearnSomethingNewEveryDay]

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!

I’m really appreciating how you teach techniques with clarity and great real examples, thank you

[@chowlissy]

What a clever strategem, and very well explained, thanks.

[@soldier7439]

You have really “upped” my game, and increased my confidence level- THANK YOU!

[@macfid]

Your presentation is fabulous. Thanks for these lessons... they're improving my understanding.

[@ShirleyKhamani]

Outstanding!! Finally someone who manages to explain it clearly!! Well done!

[@longhaulblue]

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!

[@jeyakumarvaz]

Explained in a very very way. Thank you mam.

Excellent video!

[@johnspathonis1078]

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

[@darcash1738]

I don’t see it. Oh and could you use square cell numerical notation to show your full path? I just find it very quick to lookup. Eg 3 3 = square 3 cell 3 (A9). 7 6 = square 7 cell 6, where squares and cells are numbered left to right going down: 123 456 789 When I tried it there didn’t seem to be a connection of 6.

[@johnspathonis1078]

@@darcash1738 Hi There appears to be a few numbering schemes. I think this is right. Let me know if I made a mistake. 28 - 37 - 61- 66 - 44 - 74

@@darcash1738c5 to c7 to d7 to e9 to h9 to h1. The 1,6 in h5 is seen by c5 and h1, so it can be eliminated. Oops: my bad. E9 and H9 are not a pair in column 9, since I9 is also in column 9. There is no implication link between e9 thru h9 to h1 because I9 breaks the chain.

I enjoy this so much thank you very much. Really helps.

[@LearnSomethingNewEveryDay]

Thanks Derek, I really appreciate that!

[@SunHurtsMe0001]

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

[@ConstanceCarter-h5h]

love your videos!

[@kenlamb5697]

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

[@matrixrosemary]

thank toy. this is going to help my solving techniques.

[@warrenbridle2494]

Let’s be honest, chains and other strategies (colouring etc.) are just nice ways of saying ‘trial and error’, ‘bifurcation’, ‘backtracking’ and/or ‘guessing’.

[@jasony001]

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?

[@seemashrivastava1661]

Very well explained

[@marvfj6451]

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]

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: kzbin.info/www/bejne/epOVgYyZjd5qn80 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!

[@GrimLime]

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?

[@car12moh1]

Thank you

[@LearnSomethingNewEveryDay]

My pleasure, glad you liked it Mohamed!

[@marnak24]

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!!

[@Nabuchadnezaar]

🤲🤙

[@Rood67]

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.

[@LearnSomethingNewEveryDay]

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!

She's good at what she does and definitely knows her stuff but her monotone voice finds it difficult to follow as by 1 minute in I've fallen asleep zzzzz
