so the friday competitions are considered to be the MM puzzles??? or are all the competition puzzles considered MM puzzles?
this puzzle has some very interesting patterns, I think the key is spotting the x-wing. then its choose your destiny from a number of techniques. |

| After the x-wing mentioned by Norm there is a finned x-wing on <6> that solves the puzzle |

After the xwing I had all singles to this BUG+1 here:
| Code: |
+--------------------------+--------------------------+--------------------------+
| 5 2 69 | 3 7 69 | 1 8 4 |
| 8 39 1 | 2 4 5 | 6 79 37 |
| 36 7 4 | 1 69 8 | 5 2 39 |
+--------------------------+--------------------------+--------------------------+
| 2 6 8 | 9 3 7 | 4 1 5 |
| 79 4 5 | 6 8 1 | 2 3 79 |
| 1 39 37 | 5 2 4 | 8 79 6 |
+--------------------------+--------------------------+--------------------------+
| 79 5 79 | 4 1 2 | 3 6 8 |
| 4 1 36 | 8 69 369 | 7 5 2 |
| 36 8 2 | 7 5 36 | 9 4 1 |
+--------------------------+--------------------------+--------------------------+

(BTW, the x-wing is still sitting there in cols 2 and 8 like it was when it removed all those nines ...) |

After the X-wing and a couple of basics, I used a Remote Pair on {69} to eliminate the {6} from r8c3, which left singles to finish the puzzle.
