Which is very nice.

Excellent !

So this Leo is a really good way to get into the guts of a puzzle. Same solution but arrived at in a very different way. Instead of starting out looking for a wing of some sort, consi ...

Hi Leo and welcome

It’s all about strong links for these various wings to work.

Looking for wings is helpful but also consider things from a fundamental level.

Absolutely. I think getting to understand different solving techniques is more important than step count. Variety is also the spice of sudoku life imho.

Yes that is also what I was saying. I think Earl may have meant to say xy wing and then “btte.” I think we note basics but don’t regard them as a step as the eliminations are implicit.

I think the basic must come after the <123> ?
Once you have removed the 3 from r3c3 it is just basics.

That’s right. Thanks Tom. Should have made that explicit. Whether ANP true or false or wherever the 9, the answer is that “a” is always 4

If you don't delete number 3 from r3c3 (with the XY-Wing) you don't have the LC in column 2 with number 3.

Picking up a little on all these themes there is another structure that gets us to the same conclusion as Tom’s contradiction.

Using Tom’s grid, incorporating a, is an ANP <139> at r12c ...

Hi glesco and welcome. Have you right clicked the “quote” section below ZeroAssoluto’s posting of the puzzle ?

Thanks Ghostrider. We have all sorts of solving tactics alive and well here!

Interesting - I’m normally good at puns! I like the new name Sudoshiki particularly!

….and another reason to p&p sokve!

Well done dongrave!

Patience, persistence and skill in decoding the symbols! I’m not convinced that it is “greater than sudoku” but thanks to sobspaour for providing an interesting variant ...

Good on ya virgyaa.

Well done Clement - tough puzzle. Like the skyscraper at the start - might have given me an idea. Not sure yet!

….and many thanks Immp!

Pincers for 2 at r7c1 and r3c2 are the two ends of an xy chain that removes 2 from r1c1 and r7c2.
