| 9 4 . | . . 7 | . . . |
| . . . | 8 . . | . . 2 |
| 6 . . | . . 5 | . . . |
+-----------+-----------+-----------+
| . 3 8 | . . . | . . . |
| . 1 . | . . . | . 9 . |
| . . . | . . . | 6 4 . |
+-----------+-----------+-----------+
| . . . | 2 . . | . . 8 |
| 7 . . | . . 1 | . . . |
| . . . | 9 . . | . 3 5 |
+-----------+-----------+-----------+

print and solve at your leisure
Hint: to get started, look for hidden singles ("8" box 1 and 6, "6" in box 4)
Hint #2: naked quad (1357) in row 2. |

| Yes - very good. Seemed like a very "empty" grid at the start. These days I'm enjoying these "Hards" more than many of the VHs - which are often just "Easy's" with a boring wing. |

I used three steps, probably at least one of which wasn't needed.

1. "look for hidden single ( 8 ) in box 1" is clear and specific in my book.
2. I hate it when people include hyperlinks to sites that obviously have nothing to do with the post at hand.
3. "hard" puzzles are not meant to be "easy to solve"
4. over and out |

If you want me to delete them, I will. But, I prefer my interventions to be as minimal as possible.
