How to solve Sudoku puzzles, #2

How to solve Sudoku, puzzle #2. This is a Sudoku puzzle taken from a Sudoku book which contains Easy, Medium, and Hard puzzles. This is a "Hard" puzzle, yet you will see how easy it is to solve with my techniques. It only takes me 14 minutes to solve this puzzle, even though I am going slow to explain my method. I use a pen, not a pencil, when I solve Sudoku puzzles, with my method erasing is not needed. You can try copying the puzzle on a piece of paper first, and see how you do. You may need to pause the video now and then to be sure you understand how each number is found. As with any Sudoku system, you MUST write each number down correctly. A single incorrect entry may render the puzzle unsolvable, so check twice and write down once. This video was taken with the Panasonic PV-GS35 Sailing Video Index
