To Tarek: As a novice, I'm looking for advanced solving techniques. I am working 3-star (or "medium") puzzles but would like to be able to solve them better and move on to higher-rated puzzles. I'm quite new to this puzzle and so do not understand the terminology in the solving techniques. Wondered if you (or another patient soul) could help bring me up to speed. (I have a book, but it only addresses the beginner solving processes.) There is a Tarek posted with some info that looks great, but I can't decipher. Especially concerning locked pairs and remote locked pairs and some quadrangle techniques. I stumbled onto the locked pairs thing myself, but I still get tripped up sometimes, making false logic assumptions. Anyway, any help you can give is appreciated.
PS: For comparative analyses, I'm so new that the only way I can figure out how to post a question to someone is to click on new topic. I sent this same email to Crazy Girl, as both of your postings seem to have interesting new logic to solve the sudoku's.
