After basics:
Code:
+-------------+-------------+-------------+
| 6   9   5   | 4   1   3   | 8   7   2   |
| 3   7   4   | 8   2   9   | 15  56  16  |
| 2   1   8   | 7   6   5   | 4   9   3   |
+-------------+-------------+-------------+
| 179 2   17  | 3   4   6   | 79  8   5   |
| 8   5   3   | 2   9   7   | 6   1   4   |
| 79  4   6   | 1   5   8   | 2   3   79  |
+-------------+-------------+-------------+
| 4   6   79  | 5   8   1   | 3   2   79  |
| 17  8   2   | 9   3   4   | 157 56  16  |
| 5   3   19  | 6   7   2   | 19  4   8   |
+-------------+-------------+-------------+

<79> in R6C1 and R7C3 are a remote pair that takes our <7> in R8C1 and R4C3. Or, you might see this as a skyscraper on <7>, the towers grounded in C9.

Finned X-wings on <7>: ("true" means "<7>")

Look at C17. Either the X-wing is true, or R6C1 is true. Either way, R4C3 is not true.

Look at R48. Either the X-wing is true, or R4C3 is true. Either way, R6C1 is not true.
