I have been in the "game" for just over a year now and have k-closed and with many women in clubs, pubs and bars (something that has become almost too easy after years of struggling beforehand).
I had to share with you guys the easiest pick up I have had from an opener.
For some strange reason, this night I was having difficulty picking up anyone and was getting quite irritated with this, so I came up with a plan on the spot.
I walked towards a large group of girls who were dancing together (the fear had gone at this point, it was more irritation that I hadn't succeeded yet), one HB8 had caught my eye.
I went in with plenty of eye contact and said to her "I've just caught you dancing in the corner of my eye and you definitely need some one-on-one lessons", led her by the hand away from the group and she was all over me! She was constantly trying to get my approval and I just teased and teased. She was putty in my hands!

I can't stress how much the DHV and neg theory works. It is indisputable and also you have a much better time because you aren't the one trying.
