I have placed the content of my book on my website to facilitate review. I hope Sudoku enthusiasts of all levels will visit my site to see if you find it helpful. Please provide feedback so I'll know whether I've accomplished my mission.
I applaud your attempts and love the look of it. I have not studied it extensively, but like very much what your are trying to do and wish you all success. I like referring to you site as a one place index to many techniques and good links to a lot of good sudoku sites. I perhaps would like to see more examples and sure I will with time. Shalom, Richard
