The usual: An xy-wing (146) gives r4c5 = 6, which is enough. |

After Basics (I think): Code: |
+----------+----------+---------+
| 3 1 9 | 7 2 8 | 5 4 6 |
| 2 7 4 | 3 5 6 | 1 9 8 |
| 6 8 5 | 4 1 9 | 3 2 7 |
+----------+----------+---------+
| 7 45 2 | 15 46 3 | 8 156 9 |
| 8 3 1 | 59 69 7 | 2 56 4 |
| 45 9 6 | 2 8 14 | 7 15 3 |
+----------+----------+---------+
| 19 6 3 | 19 7 2 | 4 8 5 |
| 145 45 8 | 6 3 14 | 9 7 2 |
| 49 2 7 | 8 49 5 | 6 3 1 |
+----------+----------+---------+

Play this puzzle online at the Daily Sudoku site
Basics left a very simple diagram. Couldn't see the 146
xy wing but the 145 xy wing is yet another 'double'....it can pivot on r4c4 or r6c6. |
