with all due respect Metomeya, I am not sure I believe in any one opener that has the power to create a chase over others. In the example you give I feel like it actualy instantly gives the woman the ability to put up a wall you have to try and get around. "Are you single?" "No". Just because she says no does not mean she is actualy unavailiable, but now you have a barrier to work around. NOt saying that the opener does not have to ability to work beautifuly but it has just as much room for error as many other openers.
I have always felt like the opener can really be anything as long as A:your fundamentals are there, and B: You know how to be present and adapt. It is less about the things you are saying, and more about the dynamic you are creating. So many guys get caught up in the opener and don't necessarily realize that it is more about how they speak with their body, and also how they lead the interaction. If you really want an opener to work quickly follow it with by getting a small level of compliance with it. Opening line: "Hey, I saw you here thought I would introduce my self" . Compliance: "Tell me about yourself, what have you been getting into?" Note that I am saying "Tell me about yourself" if she responds she is subcounciously aware that she has complied. This of course is only a very small leval of compliance you can be a bit more bold. How about "OH, thats a nice ring, let me see it" take her hand. I would call this a True Opener, in that it is not just a line you say but a way of setting up dynamic interaction. I actualy like to just keep my opening line very simple, it doesn't need to be anything special as long as you follow with dynamic setting technique. Another thing you can do is follow and opening line by getting her to qualify herself; "You look like you might be an artist, are you a creative person?" if she says yes then continue the thread, if she says no "Ok, then what is you are passionate about?". Or better yet, because it creates compliance and qualifcation "Not an artist? tell me what you are passionate about". Note that I have not just asked her off the bat what she is passionate about, I have taken the lead by first making a qualifying statment for her, A:it shows confidence and B: By qulaifying her for her, weather it is correct or not, you put her in a position where she must now qulaify herself. And so a dynamic is created. Opening line/Compliance, Opening line/Qulaify. Also anything that can involve some physical touch is a major plus. All of this has an amazing way of flipping the script. You were the one who approached her but now she is the one doing the work to impress by qualifying, or she is the one trying to keep up with you by complying. If you build on this foundation she subcounciously becomes more and more aware of her investment, and in turn is the one putting more effort. All the while you just sit back and lead the interaction.
Also, in regards to coming off as you are not attached and prepared to leave. I think that body language can convey this very potently. By appearing mildly bored and completly at ease it conveys that the interaction is not a big deal and you are not at all invested in what direction it goes in.
So, as I am saying, there is no magic opening line that will make woman chase harder. Woman chase because of attraction and dynamic not because of a clever opening line. Yes, asking if she is single could be a great way of starting things off, but it is all about how you follow through. Fundamentals get your foot in the door. Being present, taking the lead, and being able to adapt creates dynamic. And that is a True Opener.
