Sudoku Solving Techniques

Submitted By: sudoku lover from Germany

Hi sudoku fans!

I have been playing sudoku for myself for many years. Recently I've found a nice site aboult solving techniques for beginners and more advanced players: http://sudokusolvertips.com/sudoku-resolving-tips-techniques/

Do you now more solving strategies like the named above? I mean, some of them like naked pairs are used very intiutively but the more advanced ones are kind of new for me…

Greetings!
