I've been going through puzzles in the archive and am completely stumped on this one from 22-Mar-2013:

Code:

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


I got this far and suspect there are more basics I am missing as the discussion on that date involved an xy-wing that I have not reached:

Code:

+---------------+------------------+----------------+
| 8    19   49  | 5    2     7     | 146  13469 36  |
| 1259 1259 249 | 468  13468 13468 | 148  149   7   |
| 7    6    3   | 48   148   9     | 1248 145   258 |
+---------------+------------------+----------------+
| 4    239  5   | 2689 1368  1368  | 126  7     26  |
| 23   7    1   | 246  3456  3456  | 9    8     256 |
| 29   8    6   | 29   7     15    | 3    15    4   |
+---------------+------------------+----------------+
| 36   34   7   | 1    468   468   | 5    2     9   |
| 129  129  29  | 7    456   456   | 468  346   368 |
| 56   45   8   | 3    9     2     | 7    46    1   |
+---------------+------------------+----------------+


So what am I missing?

Thanks so much, JC! Arghhh! I don't know how much time I spent staring at the puzzle, but I'm both relieved and annoyed that it was a copy error. I really wish the puzzles would still automatically load!
