The unpredictable card is a lot like the bluff in Poker. THe game would be really boring without it. And predictable too.

I think alot of us think that getting her interest level is a predictable process where you build rapport/curiosity/challenge/control/

ONe by one, and then you stay in those modes like a prizefighter that is working you into the corner so he can bring the roundhouse.

Bad move.

Simply because she probably is more observant than you think and she can begin to see through your game.

So you bring the bluff.

Use it when you think she might be slightly cooling in interest level .

A few bluffs: Dont call her for a week, go on an exciting trip and dont tell her, take up a new hobby, show up somewhere with a female "buddy", do an offbeat date, or saying something totally out of character.

Once she starts begging you to explain yourself (she's testing to see how predictable you are) refuse to answer her questions.

Keep her off balance by bluffing. Dont let her see your cards.
