Part 5 - Eliminate the extraneous
============================
We have looked at the basic number finding strategies, but what if these are just not up to the job?  Until now we have been causally penciling in possible numbers, but there are many puzzles that will require you to be totally methodical in order to seek out and eliminate extraneous numbers.

If you have come to a point where obvious clues have dried up, before moving into unknown territory and beginning bifurcation (more on that later), you should ensure that you have actually found all the numbers that you can.  The first step towards achieving this is to pencil in all possible numbers in each square.  It takes less time than you would think to rattle off can 1 go, can 2 go, can 3 go while checking for these numbers in the cells region, row, and column.

It never hurts to repeat the one basic tenet of the Sudoku puzzle:  if something is true for one element then it has to be true for the other two associated elements.  Lets look back to something that we looked at earlier:  twins.  When you discovering the rule about twins the grid wasnt so crowded as it is in section of the Sudoku grid below.
