Sudoku Players' Forum (clone)

I found this:

Code: Select all

3    9    5
26   1    4
268  67   78

Only one box, as that's all it needs.
It's obvious the 7 and 8 must be in the bottom row, and the 6 has to be in there too. This means the 2 must be in the middle row.
It's pretty easy to see, yet it doesn't exactly fit with any techniques I know. A sort of part-hidden-naked triplet? I don't know. The two programs I tried that show all possible moves didn't show anything there either.
So, what do we call it?

really? the 6 must be in the last row?
how did you reach this conclusion?

Hmm. I have no idea. It's wrong.
I guess this is called "don't write posts at 3am".
