Sudoku Puzzles

So I'm first today.

30:26

wow, I've never been here before....

Hello Molly!

Welcome, Anna/Thailand

The sun has come out and it has turned out to be a beautiful day. I hope everyone has a good one!

Aww, she's adorable!

She's beautiful

sorry.....dog lover here! 16:25 good mAen to all (even molly!)

Molly is lovely. No guesses today.

13:36; thanks for saving Molly and sharing her picture, hope she's brought a lot of love to you.

After yesterday's cream puff, today's puzzle makes quite a contrast.
Plain chains, max depth 4, are sufficient to take care of today's puzzle. However, I do not believe there is any way to use only one non-native elimination step (like yesterday's).

Hello Kitty... hehe
So, do you know stirfry?

we have a molly too but she is a big fluff ball

It's been awhile since we've seen a beloved pet photo. Molly is beautiful. Thank you for sharing her.

Time:11:36AM
Hai good Picture,Nice to see everyone here.Today tough puzzle is easy by removing all the probabilities to two digits.

22:45 With lots of guesses and most of them wrong! oh well couldn't wait to see Molly.. I love all cats but prefer Siamese..I have two that I adore.. my family don't share my obsession but they do share the cat hair much to their disgust. ( and the cats aren't even allowed inside!)

A proof for tough sudoku of 04 02 2007:

1) Start at 23 filled - the given puzzle. Unique Possibilities to 26 filled. (UP 26).
2a) Locked 4s at e89 forbids e46=4
2b) Locked 4s at gh6 forbids ghi5,hi4=4 UP 28
3a) pair 37 at bc8 forbids ab7,ade8=3 and forbids c9,de8=7
3b) Locked More...

Not tough. Interesting, though.
