I'm new to the terminology, so let's say the 9x9 boxes are represented like so:

ABC

DEF

GHI

One 8 is missing from each of the three middle boxes D,E,F.

In column 2 (Box D), an 8 must be in row 4 or 5.

In column 6 (Box E), an 8 must be in row 4 or 5.

In column 7 (Box F), an 8 must be in row 6 (by elimination of 4 and 5).

See how the two blanks in box C are vertically aligned?

Without knowing what order they're in, you know one is a 2 and the other is a 6 (the two remaining digits for that box).

If you assumed they were filled in and took up the only available 2 and 6 for their column, you might uncover a 2 or a 6 in one of the other two columns in box F.
