A Killer Pair is a Killer Subset of size 2.
How it works
Here is a simple example:
The cells R78C6 = 6 = {15} or {24}, i.e. they must contain either 1 or 2. They therefore form a naked pair in conjunction with the {12} in R3C6. This allows us to eliminate {12} for the rest of column 6, which means that R4C6 = 3.
