1. Basic techniques to UP = 26
2. (5)h6 = (5)de6 - (5)f5 = (5-2)f3 = (2)ac3 - (2=139)a124 - (9)a5 = (9)h5 => h6 <> 9, h5 <> 5
; UP = 81

I've posted comments for you on the Apr 27 and 28 tough pages. (I suggest you see Apr 28 first)

To others with experience in the broader Sudoku community, I would appreciate any feedback on the Apr 27 comments. Sorry if I was a bit long-winded.

That looks like fun except the part were you can see/hear what the neighbors do and/or doing.

way too long

Interesting solution with an "anti-5" in h6! Never approached it that way, but it seems to be a good technique when needed.

Hi All,
My special thanks to rwm, farpointer and ttt who posted replies relation to my 'requests and 'solutions') postings on the 27 and 28 April Toughs. I will reply, after digesting them, on those pages, and add a comment on the current Tough page to say that I have done so.
Best regards, Neil

Did it! Looks like a lot of people having fun. But isn't Australia one of the most sparsely populated places on earth? Doesn't look it here.

another 2 set path (shortest above is 4):
1. basic techniques UP 26.
2. (4)f5=(4)abc5-(148=5)bi6,d6 => ~(5)f5
3. UP 81.

rwm: I looked up Kraken and got fish, but still have no clue what a Kraken Cell might be??? (unless it's just the idea of using derived strong sets?).

--read sotir's proof jul'07. seem's like a kraken cell is just a polite way of dignifying: try every possibility in cells until something useful turns up. (in my field - C# programmer - that's called 'brute force' search).
