How it works
Three cells with two candidates each: a pivot holding X and Y, and two pincers it can see, one holding X and Z, the other Y and Z. The pivot is either X or Y, so one pincer or the other is forced to be Z — we just don't know which. Either way Z lands in one of them, so any cell that sees both pincers can't be Z.
Try it
Look at Row 1, Column 3, Row 2, Column 1, and Row 8, Column 3 — three cells with two candidates each. Let's pencil them in, then see why 1 can't survive where they overlap.
