Welcome to this Sudoku Video Turorial - Sudoku Pairs Chain.. It is part of a series of Sudoku Tutorials that I am basing closely on the Sudoku Analyses Techniques which can be found on the LittleGogs website Analyses Section

Duncans Specification of a Pairs Chain:
Pairs Chain: A linked Chain of paired Possibles. The ends of the Chain have the same value. The linking elements may have different values. If one end of the Chain is 'false', then the other must be 'true' and vice-versa. Any Possible that can 'see' both ends of the Chain may be removed.
