I have been experimenting lately with Direct Game. And doing direct openers.
One that actually works is just confidently walking up to a woman and telling her that she looks amazing. If you say it with a smile and not needed any sort of affirmation for yourself, but more of just something that you are noticing about her.. it goes really well. It always works to compliment something about what she is wearing.. something along the line of "I really like your look, you have a great sense of style. I think it is awesome how you matched your shoes with your shirt (or whatever - but make it believable)." If you are observant, you can always find something to comment on.. women work hard to look good so finding the result of this work is usually pretty easy.
Try it out.. and let me know.
