Code: Select all
*-----------*
|4..|.5.|1.8|
|7..|19.|5..|
|135|...|29.|
|---+---+---|
|.73|..5|9.6|
|.4.|...|72.|
|6..|7..|8..|

|.17|.46|389|
|3.4|.8.|6..|
*-----------*

You missed a couple of intersection moves, as shown in the following diagram.

Code: Select all
*---------------------------------------------*
| 4   269 269 | 2-6  5   *237    | 1 367 8    |
| 7   268 268 | 1    9   *234    | 5 346 34   |
| 1   3   5   |#468 #67   478    | 2 9   47   |
|-------------+------------------+------------|
| 28  7   3   | 248  12   5      | 9 14  6    |
| 589 4   189 | 689  136  189-3  | 7 2   135  |
| 6   259 129 | 7    123  1249-3 | 8 134 1345 |
|-------------+------------------+------------|
| 89  689 689 | 3    17   179    | 4 5   2    |
| 25  1   7   | 25   4    6      | 3 8   9    |
| 3   259 4   | 259  8    29     | 6 17  17   |
*---------------------------------------------*

There is a pointing pair of 3's in Box 2 (cells marked*) which removes 3 from r56c6. More decisively, there is a claiming pair of 6's in Box 2 Row 3 (cells marked #) which removes 6 from r1c4, solves that cell and the puzzle.
