The New Sudoku Players' Forum

[Xcelerate]

I recently read the guide from sudocue.net, and I found it to be very useful. Reading through the guide, it said that most published puzzles can be solved using all the methods before "fishes" (in this guide). So I tried a few puzzles, and I found that the techniques presented made solving much easier, so I decided to go onto a fiendish one. Well now I'm stumped:

Code: Select all

. 3 . | . . . | 7 4 .
. . . | . . . | 9 8 .
. . . | 4 8 5 | 6 2 .
------+-------+------
2 . . | . . 9 | . . .
. 6 . | 1 . 4 | . 3 .
. . . | 8 . . | . . 9
------+-------+------
. 9 6 | 7 3 1 | . . .
. 2 . | . . . | . . .
. 1 7 | . . . | . 6 .


This is what I have so far:

Code: Select all

568   3      258  | 269   1269   26    | 7     4      15
456   45     245  | 236   1267   2367  | 9     8      15
19    7      19   | 4     8      5     | 6     2      3
------------------+--------------------+-------------------
2     8      1345 | 35    57     9     | 45    17     6
579   6      59   | 1     257    4     | 258   3      28
13457 45     1345 | 8     2567   2367  | 245   17     9
------------------+--------------------+-------------------
48    9      6    | 7     3     1      | 28    5      248
3458  2      3458 | 56    456   68     | 1     9      7
458   1      7    | 259   2459  28     | 3     6      48


I have tried locked candidates, disjoint subsets, all the "basic methods", and I can't seem to get any further. Since this is a publication puzzle, I wouldn't think it would require any of that more advanced analysis... any help?

Look at column 6 and find a naked triple or a hidden pair, whichever you spot first.
