A rainy, dreary day here, perfect for sanding and painting in the basement--yuck! Hope you've got something more exciting planned. Enjoy!

Improvised waterslide...could be risky!
Grey day but nice breakfast with daughter Yanie. How nice to meet your number one daughter after a long absence. Very grateful!

Splish! Splash! I was takin' a bath!

Good afternoon to all! 'Okay, who pushed me?'

When we did things like this when we were kids, we always yelled, "Geronimo!" I assume that, in a Native American language, this means something akin to: "I'm doing something very stupid ... but it's fun, and I'm young and reckless!" Ah ... the Good Old Days ...

9:29 to you all.

I think that is one of Wagdy's photos.

everybody.
23.27 with possibilities. I'm studying the link I was given on Sudoku methods but only practice makes the stratagies come naturally! Hopefully my times will improve.

8.50 For a sec there, I thought they were cows!

Nice but not difficult.

Yes the good old days Judy, when kids could be kids.

1) Start 23, ---> UP=37

2) YW: (9=5)h2-(5=2)h1-(2=9)f1, -->f2<>9

3) fc: (1)i456=(1)h4-(1=9)h3-(9=6)d3-(6)f2=(6)f5

--->f5<>1, UP=81

Sotir, Your chain in step 3 does not forbid f5=1 because i456 do not ALL see f5.

I do admire the effort though.

Can anyone see anything wrong with the following proof of f5<>1? (I'm still in gb's sandbox ...):

At sotir's step 3:

3)5g5-(5=2)g1-(2=9)f1-(9=6)d3 ...

This leaves d5 (to my way of thinking) as if it were confronted by a naked pair (heavens!) of 56 YW style (i.e. 3 strong links), pincers at g5 and d3.

Therefore assert d5=2, e6=1, f1=6 UP81.

To answer my own question:

3a) Y style chain as above

3b) 6d3-6d5 reveals naked quad 1235 forbids f5=1

3c) 9f1-(9=1)f9 ditto

(maybe I'm getting it)

best to all maen-ers
