... by: P MajumdarIn the wright-up for Bi-Value links, you have stated "...and highlighted all the cells with two remaining candidates." [please refer to 'bi-value links' diagram on the side of the wright-up.]
Out of 81 cells you have highlighted 18 cells with yellow. These cells are- A1,A9,B5,B6,B7,C2,C7,C8,E2,E8,E9,F4,F6,G3,G4,H9,J5&J9.
Please explain, why the cell E3 (also a bi-value cell, containing the candidates 4 & 9 only) has not been highlighted. Thanks.

I missed that cell when I coloured it. Diagram now updated. Thanks for the alert!
