So I've used a lot of different openers on Tinder cause I tend to get a good amount of matches. Lately I've been using an opener that hasn't failed yet. Basically I look at their pictures and try to find something that I can either ask about or ask a question related to it. So for example the girl might have a picture of skiing and I would ask "have you ever snow boarded"... (I got a number off that one) It separates you from the crowd and engages them pretty well. From there I follow this approach http://www.reddit.com/r/seduction/comments/1hzg9g/how_to_tinder/
