Bob's my uncle, so she said
emm, the starter of this thread
Choose a rhythm, this trochee?
Surely she will disagree.

If not done as she has told
something evil will unfold
Glum or dumb, I must obey
Her constraints communique

Constraint: A restriction derived from the rule. Sometimes used as an alias for house.

[emm]

First thing I would like to say -
What constraints communiqué?
Glum or dumb (you saw that too )
(I was just being kind to you).

My idea’s prescriptive-free.
Sing trochee! It’s fine with me!
Any other song you croon,
Sing it here (if it's in tune)!

Sing to us unplugged or wired,
We don’t mind, we’ll be inspired!
One Sudop'ian word’s the task -
Is that such a lot to ask?

Sudop'ian: Pertaining to Sudopedia, the free Sudoku reference guide.

Yesterday, I was taken to task
Distressing! "About what"? you do ask.
About! Well, here's the rub
It's my union sub
Settling it, has left me quite aghast.


Hidden Subset: A Hidden Subset is formed when N digits have only candidates in N cells in a house.

Cleverly hidden, MCC...

Here is my returned favour, which might be a tad bit naughtier than usual...
Go light on me please... I'm poetically handicapped...


Two couples trot along a stream.
Burning hot, they go for a swim.
No togs to wear, they just strip.
"There's no shame, let's skinny dip!"
Swinging naturists - scary theme...


Naked Quad - 4 cells that have candidates for only 4 digits and are collocated in the same house.

[Mike Barker]

These rhymes are incredibly cute
As much fun as climbing a chute
So strike up the band
I'll come lend a hand
To the stack add this auspicious beaut.

chute: a band or a stack
band: three boxes in a row
stack: three boxes in a column

[MCC]

Years ago, I went up in a plane
For charity, must have been insane.
About two thousand feet
Parachute opened. Neat.
No box! No ER! Let's go again!


ER = Empty Rectangle: is a single-digit solving technique which uses the absence of candidates to perform an elimination.

Box: A group of 9 cells in a 3x3 formation.

Chute: A subdivision of the grid that encapsulates 3 boxes in a line.

(ER or E.R. = Emergency room, after a very bad landing.)
(Box or coffin, after a very, very bad landing.)

Hey, nice one Mike. Very nifty getting 3 defs in one. Very funny, MCC. The alternative defs are great. Are we all getting autobiographical here?

I take it yours is autobiographical, udo, you Aussie swinger! Free expression is a valid form of poetry and I’m all in favour of you expressing yourself in this way. I can’t decide if you get 0/10 for not including the word or 10/10 for visual imagery (BTW, everyone note that in Australia swim does rhyme with stream! That's just how they say it! )

Hope your cricketers swing well today!

To udo the water looked cool,
So he stripped off and jumped in the pool.
But his naked subset
A sorry end met!
First look, and then leap - that’s the rule.

Naked subset: If you need me to explain this then you’ve been spending too much time at Sudoku.

[MCC]

The parachute jump for charity was for real. A small plane just big enough for seven jumpers, a small plane with no door
It was too windy that first weekend to jump, so two of us went back the next weekend and seven of us went up, two novices and five experienced jumpers. It was still fifty/fifty whether we would jump or not, it being judged that the wind was still too strong. At 2000ft they decided to let us two novices jump, we found out later that we were the only two jumpers to jump that day because it was too windy to let the others jump. Both of us got down ok


Bob, a prisoner of old, did flee
His cage, chained to a dwarf, his buddy
Both killers, on the run
From men, each with a gun
Guardians, who'll constraint their folly.


Buddy or peer: Is a cell that shares one or more houses with another cell.

Cage: Isolated part of the grid in a Killer Sudoku, with the sum of all caged cells in the top left corner.

Chain: A series of linked cells or candidates.

Constraint: Is a restriction placed on the Sudoku puzzle.

Guardian: Is a candidate that prevents a Broken Wing to form a loop with an odd number of strong links.

Killer: A Sudoku variant where givens are replaced by cages labeled with the sum of the digits to be placed inside them.

Let's say my visual imagination is better than my courage about "free expression"...

(BTW, everyone note that in Australia swim does rhyme with stream! That's just how they say it! )

I suppose it's a stupid question but I've always thought swim rhymes with stream... How else should they be pronounced in New Zealand?

Hope your cricketers swing well today!

They swung pretty well against your cricketers tonight...

I'm a bit thick now... Whatever "sorry end" met my "naked subset"?

FYI I did go to a pool today for a swim... I wasn't naked, I didn't jump or leap, and the water wasn't cool... I did look at the water before I entered the pool...

My problems with puzzles are vast
and prize winners tend to be fast.
I am hoping the same
will submit in my name
and by proxy win goodies at last

[emm]

No need for proxies, Bigtone, you will win prizes! (Luckily for you there’s a last digit in Sudopedia.)
First prize - perfect beat, perfect rhyme. Total = 9/10 (You missed the final period. Sorry, this is a tough school.)

Bigtone is a poet but shy,
Though Big Numbers he does on the fly.
Needing proxy or pun
He did n-1.
Now he's Bigtoe - a wholly new guy!

Big Number: Collective term for given and placed digits, as opposed to little number for pencilmarks.


Udo, I take it your skeeny deeping question is rhetorical.
Too bad about the cricket - we did what we do so well, look like we will surely win, then lose. Hey, there’s always the World Cup!

Should I have highlighted the xy-wing in the last line? It looks a bit obvious to me

Thanks for kind words, emm

[udosuk]

Bigtone, the convention of this thread suggests you should write a glossary at the end of the post in the format:

xy-wing: ...

If you'd done that it would have made you look very smart, much like MCC's "hidden subset" poem (which doesn't contain the word "hidden" btw, as the "hidden" is "hidden in context" )...

Udosuk,

I know. It was just that it took me so long to come up with a (printable) xy-wing limerick that I wanted the team to wonder why I was writing and find it.

Am working now on xyz-wing. This could take a while!

[MCC]

Bigtone ponders "How can I include
A tricky term into a rhyme"? Dude.
"Easy as A.B.C
Or as your X.Y.Z.
Wing it, so's people don't think you're rude".


The Z is pronounced the American way - Zee rather than Zed.

XYZ-Wing: Is an extension of the XY-Wing. The pivot cell also carries the Z candidate.
