Sudoku Demonstration - 2-String Kite Technique (Example 01)

As I've continued to grow in my ability to solve Sudoku puzzles, I've also continued to seek out more advanced puzzles to push and challenge myself to learn and understand techniques that are necessary in order to complete "Hard+" puzzles. Keys to finding and using a 2-String Kite (in this example, we're filtering on the number "3"): 1. Look for one column and one row where only two possible candidates exist for a number (ie: Column Seven has two cells where a 3 is possible and Row Four has two cells where a 3 is possible). 2. Identify if the Row and Column intersect in a way that causes one cell from the Row and one cell from the Column to end up in the same "house" where the intersection of the Row and Column occurs. 3. Identify the "foundational" or "base" cells of the kite (the ones that ended up in the same "house" - these form the center frame of the kite) and identify the "relational cells" or "wing tips" of the kite. 4. Perform an "if this, then that" scenario analysis on the base cells: Notice what happens when you ask yourself "If THIS cell is a 3, then what happens to the other three cells that form the kite?", and then ask the same question while choosing the "other base cell". 5. You will notice that, in the first scenario, two cells will be "green" (possible) while the other two cells will be "red" (not possible) - and you will also notice that, in the second scenario, two cells again will be "green" while the other two cells will be "red" (noticing that "opposing cells" are either green or red in the two "if this, then that" scenarios). 6. Identify the "elimination cell" (the cell where the possibility of a 3 can be eliminated). If anyone watching this video would like to see other examples of this particular technique, let me know and I'll post one or more videos demonstrating it. Or, if you have a question, feel free to send me a message on YouTube and I'd be happy to discuss it with you in more detail :). If you'd like to keep growing in your Sudoku skills, but you're not quite ready for this level, keep practicing beginner to intermediate puzzles until you feel more comfortable and confident to take on new challenges like this and other techniques I'll be demonstrating in the months to come. The application I used for this demonstration is "Hodoku" hodoku.sourceforge.net/ More info about the "2-String Kite" technique: hodoku.sourceforge.net/en/tech_sdp.php#t2sk
