All the possible positions of the value 2 in three different cols are in the same three rows. Because the number of cols matches the number of rows, and because each col must contain the value 2; each row will have a 2 in one of the intersecting cells.

Hence other possible positions of the value 2 that are in the rows but not in one of the cols can be removed.

Therefore we can remove C1-2, D3-2, D9-2, F1-2.
