Since you sad after the basics, I am just wondering did I miss something...
Is there "easy" method to get 1 in r1c9.
What i mean is I had to use Swordfish patern but with 4 rows (r1, r4,r8,r9)
to get that 1 in r1c9. So I am wondering is there easier method to get it?
After that and the rest of the basics that come out of that 1 in r1c9, mentioned XY wing realy doeas it... |

+---------------+----------------+-------------+
| 1 2 468 | 359 4589 89 | 348 369 7 |

there are two 1's in block 8. All the other 1's in c5 can be removed.
This leaves a lone 1 in r1. |

| The 148 XYZ wing with pivot in R8C7 will also solve it. |
