I don't normally have many problems with mid-game. I usually keep it as short as possible, then either go home with the girl or get out of there quick with a number/date lined up.

However, in a couple of weeks I'm visiting an old female friend who lives abroad now. We haven't seen each other since we were 16 (so my "gaming" wasn't up to much then), about 7 years ago. But she's pretty hot now, so it would be rude not to try my chances

However, do you need different strategies for mid-game when you're essentially forced to spend a whole week with a girl rather than bailing after 20 minutes or so? I'm staying at her flat, so I can't do the usual direct hit and run tactic of get the number/date/lay and then get out.

agreed with magic method.

If you lead a decent life, you shouldn't need a routine for "mid game"

just go with the flow, empty mind, small talk and dig deeper into her topics. I can talk forever like this without it fizzling.

was hard at 1st though, but you should be normal things like watching movies, hanging out with mates, going out, going to restaurants, going on holiday..

This naturally gives plenty of "mid game" and chat, all you gotta do is escalate eventually when there is a good vibe.
