I am always open to learn something new and that brings me to asking this. I am looking to expand my existing skills: I am at hard level. I am Google articles and reading this and that and picking up small things here and there but as you all know the Internet can and does have more garbage than help. Is there a site or/and book that has better lessons/examples that I can learn from?
Everyone I know now is simply from doing the puzzle.
BTW when it comes to playing the game, I prefer the books over anything else. I have the app on my phone simply in case I need to kill time somewhere but I prefer the organic method of pen and paper.
