An easy solution to this puzzle is simple coloring on (8)

However, a more fun solution (for me) was an Almost XY-wing(79-8) marked * with (89=1)r6c9 plus transport
Code:
*--------------------------------------------------------------------*
 | 79     2      1      | 39     389    6      | 4      78     5      |
 | 79     4      5      | 19     2     a18     |*78     3      6      |
 | 3      8      6      | 4      5      7      | 2      19     19     |
 |----------------------+----------------------+----------------------|
 | 1      67     9      | 8      4      5      | 3      67     2      |
 | 5      367    8      | 1369   379    2      |*79     1679   4      |
 | 4      367    2      | 1369   379    13     | 5      16789 *1=89   |
 |----------------------+----------------------+----------------------|
 | 8      5      3      | 2      1      9      | 6      4      7      |
 | 6      1      7      | 5      38     4      | 89     2      389    |
 | 2      9      4      | 7      6     b38     | 1      5      3-8    |
 *--------------------------------------------------------------------*

[xy-wing(79-8) plus transport: (8=9)r6c9-(9=7)r5c7-(7=8)r2c7-8r2c6=8r9c6 ; r9c9<>8] = [1r6c9-(1=3)r6c6-(3=8)r9c6 ; r9c9<>8] ; r9c9<>8
