For FAQ go to my web site http://www.sudokuguy.com

In this tutorial I show the importance of 3 numbers in a row or column within a block and the resulting ramifications of TMB and LCR. This technique can be very helpful in puzzles of all levels.
At approx the 15 min point I cut to the end of the puzzle to save you time watching what has already been covered in previous puzzles as well to allow you to see the mess your puzzle may look like when you don't remove small numbers. Have fun.

NEW you can now go to my web site and see an INDEX OF VIDEOS under strategy headings. Clcik on the number and it will take you to the video of interest. http://www.sudokuguy.com
