Play this puzzle online at the Daily Sudoku site

For a change I found the XY wing first- 189 pivot r2c3 setting
r6c8<> 1. But I did notice there's at least one more W wing- a 68
setting r4c2<>8 with all falling. I suspect there might be more.....

Totally stumped.
'Hint' indicated column 2 row 8 = 1. Why?

Code:

+--------------+---------------+---------------+
| 4 689 689 | 2 16 5 | 3 18 7 |
| 1 3 5 | 7 9 8 | 6 24 24 |
| 2 68 7 | 136 1346 34 | 18 9 5 |
+--------------+---------------+---------------+
| 5 689 4 | 689 68 1 | 2 7 3 |
| 3 1678 168 | 5 4678 2 | 14 146 9 |
| 67 2 169 | 369 3467 347 | 5 146 8 |
+--------------+---------------+---------------+
| 678 4 16 | 138 12378 37 | 9 5 12 |
| 78 17 2 | 4 5 9 | 178 3 6 |
| 9 5 3 | 18 1278 6 | 1478 1248 124 |
+--------------+---------------+---------------+

Obviously I fail. Using basic steps I am only able to get to this point. What steps clear row 5, column2 and column 8?

This is one good puzzle.

Hi 'Ema': To get you going again- theres a sole candidate number in box 5 and a hidden pair in column 2 and the rest is sorted if you look at column 9 and box 9 very closely........

Thank you. It was the block 9 '1s' that I missed. It was staring me in the face the whole time.

The 18/89/19 is a thing of beauty also.
