The point of opening is only to open the conversation.. I can't tell you how to have a conversation with women. It depend on you, you're style, the woman you're gaming, etc.
That being said, here's an example of a FB conversation I had with a girl I gamed last weekend:
Me: You're unbelieveable...
HB: ???
Me: Not even a "hi" since we decided to become best friend for life! Unbelieveable... (It was actually bullshit, I never said such things...)
HB: Aha I don't remember that at all sorry!
Me: I was at LEAST expecting some "good morning" texts! ahah
HB: loll but I don't even have your number...
Me: Oh, xxx-xxx-xxxx... Hope you will change your bad habit tommorow morning
