Remote Pairs is an advanced technique. Its name comes from a collection of locked pairs that are linked together remotely. The simplest way to picture them is to form a path through an **even** number of locked pairs (i.e. an even number of squares containing locked pairs). The intersection of **both** ends of the path cannot contain either of the digits in the locked pair. The path may consist of two, three or more locked pairs (i.e. 4, 6 or more squares) and the intersection might be on a row, a column or in a 3x3 block.

There are two linked occurrences of a Locked Pair in <28>. R2C1 is the intersection of the ends and no matter which way around <28> actually go, R2C1 cannot be a <2> or <8>.

There are two linked occurrences of a Locked Pair in <26>. R5C6 is the intersection of the ends and no matter which way around <26> actually go, R5C6 cannot be a <2> or <6>.

There are three linked occurrences of a Locked Pair in <26>. R7C7 is the intersection of the ends (i.e. buddies of both ends) and no matter which way around <26> actually go, R7C7 cannot be a <2> or <6>.
