nisaba, Sulis, and tarotbear are right. If you aren't prepared and don't know tarot well enough (you said you just started not long ago?) then yes/no questions are going to be extremely difficult. It's far, far easier to just avoid them altogether, and a big pain in the butt to try to figure out how they are working for you. But then, if you are the type who likes to push the limits and experience new learning by trial and error, you just might succeed with them in your own way- I believe that I have.
A woman asked me, "Will he contact me?" And the cards told me "No, because he doesn't want anything to do with you or the child you share." I got all kinds of details that were correct to the situation (like the guy's father was telling him to step up and be a man) from the yes/no spread that I was using. It's all how you work it. And so she got mad and contacted him. Was I/tarot wrong? Nope. When she contacted him, he yelled at her and told her to leave him alone- she was crazy, she was *this, she was *that... blah blah blah. It was quite obvious he didn't want to own up to that kid. I'm pretty sure he was never planning on contacting her. But they did have contact because she initiated it and her response to me before contacting him was along the lines of "I can't believe we will never have contact again" and I said "I didn't say you would never have contact again, I said that he wouldn't be contacting you", and so you see, she didn't ask me the question she really intended to know which would have been "Will we have contact again?" and that is the problem with yes/no questions... the people behind them. Tarot will most definitely split hairs and answer the exact question you ask of it, so it's important to get the question right from the start because yes/no questions leave very little room for one to mess up. That's probably why others don't like them so much; yes/no questions leave very little room for cushion-of-error on the reader's part without a round-a-bout story to fluff things up and it's much more difficult to be exactly right.
But I like the challenge. Maybe you will too.
