Smile back, wave her over to come over to you and just escalate. You Dont need to game at this point. Gamey stuff will probably do more harm than good

Let's agree to disagree your post is huge and so gamey. I am speaking from my experience and perception

Well I would just say ask yourself, "Have I laid the girl yet?" If the answer is 'no' then you still need to game her. I was simply saying that you just start in qualification since you already have attraction. Remember the only gamey things you are doing are the compliance tests and the false takeaway which serves as a compliance test. If you use kino tests on the girl thinking that you 'don't have to game her' then you risk telegraphing too much interest. It all depends on what state she's in. Hormones play a role. Women who are ovulating will be very receptive to heavy escalation if they like you while women who are in logical male mode will be turned off at your inability to realize that she isn't in a sexually receptive state. Escalation still needs to be calibrated otherwise you will look thirsty which is a major game killer. "Have you laid her yet?" The answer is 'no' so you still need to game her. You don't need to run attraction stuff. I agree with PEBBLE in that it will cause harm as it is a form of overcompensation do to insecurities about not having enough attraction. But qualification is another ball game. Some girls won't need gaming. But 10s will. If you aren't having to game then you are PUNCHING BELOW YOUR WEIGHT. You don't have to game because the girl already sees you as higher value. Physical attraction doesn't necessarily set a higher value frame. It creates something called lust. It helps with building comfort according to Adam Lyons. Gaming is more than building attraction. What about connection? What about flawless escalation in which you escalate without looking need while increasing her buying temperature.

In any approach, just a little bit of game is OK.

So if she is looking at you, you can approach and say something like,

"Hey, what's up? Do you look at every guy like that or just the one you really like...?"

And then you continue talking in a normal way, asking her normal questions.

In terms of escalation, I think your question was more about approaching itself, so I won't go into it too much,
but after you start talking, remember that you have the advantage because she already likes you.

Your only job is not screw things up too much by gaming her too much. So nothing weird, normal questions
and have some fun.

The reason I ask is that there are a lot of times when I got IOI's but I don't follow up because...to be honest, I'm more used to cold approaches at this point (which is completely weird).

From my experience being more used to cold approaches is because you are afraid to let the girl dictate the pace of the interaction - i.e. you might have time to calculate when you're about to use a cold approach but when the girl gives you an IOI it is a signal that you need to approach then and there. For me, this always means that I am analysing things too much because I feel I need that time period to think of something 'clever' to say.

Hope that helps, newbie to newbie.
