This is an opener that seems to do the trick online, it's a bit slow, but more fun than others i think.
Look at your targets presentation, especialy the pictures and make a mini cold reading from that. Make some statements about her personality and just give them to her. "You are calm, tough when you have to, but mostly warm... bla bla"
It's not hard to do it, just think about how you put the statements... Even the most stupid things work, like "you sometimes experience low self asteem when other people say bad things to you..." But make it most positive things about her. Remember, it's what she thinks about herself you should point out, not what she actually is like
She will think it's fun even if you get it wrong.
I think it's good to follow up with a neg you get from the reading
The best thing is that it's also quite interesting for me to do:)
