Help!

If anyone has the time to figure this out for me I would appreciate it. I was stumped on this puzzle for days - kept starting over in case I had made a fatal error - and the same result each time meant I was at a dead end. The only way I could finish was to get one hint and the rest was easy. I want to know how to get that cell with the available possibilities!

Here is what I had when I was stumped. I'll place a * in the spot where the hint said there should be a 3.

5-- --3 -8-
73- --4 -5-
214 --- -*-
-52 --7 6-8
-87 6-2 315
6-- 5-- 2--
--- --- 82-
82- 4-- -69
-7- 82- --1

I looked for x and xy wing and triplets to no avail.
Thanks! T

Have a fresh look at row 3. The 5 and the 8 are confined to r3c5 and r3c6.
The only place left for 6 in this row is in column 9. Then the only place for 3 in the top right-hand box is r3c8.

Steve R is right. Here's another way to look at it.

The only possibilities at r3c4 are {7, 9}. The only possibilities at r3c7 are {7, 9}. The only apparent possibilities at r3c8 are {3, 7, 9}, but the {7,9} are ruled out by the naked pair in row 3. dcb

I finally see the camouflaged pairs - they were pretty sneaky!

Thanks again, T

I would really appreciate an answer on this. I've only been doing these puzzles for about a month, and there must be some bit of logic that I've simply failed to grasp.

R2c8. He has a 5 in that spot, while I had it as being either a 5 OR a 9.

I did, however, have an 8 in r2c3.

Other than those 2 differences our 'solutions' were the same at the time we became stumped.

I can get no further in this puzzle without resorting to trial and error. Please, how does one eliminate the 9 from consideration at r2c8?

I'm ashamed to admit that I had to create a grid of possibilities to get past this roadblock. Even the grid didn't help but I'd be more than willing to show it if it will help.

Incredible...

One reads the forums about puzzles that one has already easily (well, relatively easily) solved, and wonders about people who've missed what seem to be obvious clues...

It's a bit sobering when the shoe is on the other foot...

Thank you David. I, of course, have no idea how I missed seeing what now seems to be as plain as the nose on my face.

Sheepishly,

Bo
