I think
this blog post sums it up quite nicely.
Personally, I hate the dating games and rules, but a lot of my friends think ignoring the girl and not being available works wonders for building attraction.. and I'm sure it does for some girls.
If I go out on a first date and would like to see the girl again, I'll call her the next day to set up another meeting. It may not be as effective, but at least it's honest. Hopefully it will work someday soon
