Hmmm. I ran into a wall on this one. No wings that I can find (X, XY, XYZ, or W), and my chains all wind up at inconclusive dead ends.
Code:

+--------------+-----------------+---------------+
| 137 235  257 | 8     135   6   | 9    4   35   |
| 13  4    569 | 1359  7     159 | 8    36  2    |
| 8   3569 569 | 4     359   2   | 356  1   7    |
+--------------+-----------------+---------------+
| 9   35   4   | 135   1358  7   | 2    38  6    |
| 37  8    67  | 369   2     4   | 13   5   139  |
| 2   356  1   | 3569  35689 59  | 7    389 4    |
+--------------+-----------------+---------------+
| 4   7    29  | 12569 1569  8   | 1356 369 1359 |
| 5   29   3   | 1269  4     19  | 16   7   8    |
| 6   1    8   | 7     59    3   | 4    2   59   |
+--------------+-----------------+---------------+

Play this puzzle online . The player says it's a "too hard" puzzle! Hmmm.

Not as messy as the last puzzle I posted, but even with all the bivalue cells I'm drawing a blank. Any suggestions?

Yes!! That did it! After your hint, the eliminations exposed another skyscraper (that's what I usually cal them) on the same digit. I gotta start looking for these patterns before banging my head against the wall trying for the more complicated ones.

Thank you very much!
