The strong link is in box 5. The easiest way to see this sort of W-Wing is to note that <1> is not present in r456c4. Since <1> must be in either r456c5 or r456c6, one or both of the {12} bivalues must be <2>. |
I See! I See!
My analysis approach is still to mechanical. I never even considered a strong link within a box; I only looked at row/columns. In this specific situation, the comment by Steve about the link being in column 4 only confirmed looking in the same old manner. I can only hope that with continued effort and support over time I will become better at the logical/conceptual approach to analysis.
Thanks very much ......
