Solving a Hard Level Sudoku Puzzle with Skyscraper Swordfish AND Forced Chains!!!

E16: Three advanced level strategies are used here, you are going to love this puzzle! It starts out very easy, so you might want to skip to about half way through when the good stuff starts. I have to use the skyscraper and swordfish and then forced chains to get to the end, but its lots of fun and very challenging. I hope you enjoy, and, I hope you learn something!!!
