i'm kinda new here, i think i have read most of the "for n00bs" articles and i still have to use the glossary for most of the terms but i have a doubt and I have not seen anything on the subject.

how do you choose your target? i mean: how does one knows which girls are the mos likely to be available or the ones with the most chance of success?

I assume that most pick up artist do this by instinct and that they can read a crowd in a second and the go for the most probable or desired girl but i would like to have some pointers.
