Most of the currently popular strategy–what I call the Standard Strategy–is a ruse. The rush to fill all the vacant cells with marginal notes is intended to throw you off track and relinquish your own deductive power to those who would mislead you–or outright lie. Mapping out a linear path that meanders through the matrix is not only inefficient; it misses the mark completely. One concept that is completely unknown in the Standard Strategy is "coupling" where a set of cells/digits in a Box can link Cells in one Band to another set in Stack. The key is identifying sets of Cells and Digits which share common values.
