There're two main situations where you can *close a woman.

First, tipical one, you are talking for a while, working your magic, and you are getting some IOI. You move few centimeters forward since you are close and go for the kiss.

Second, only for clubs, you find a woman willing to be kissed and go for it. Of course many more things should be present, but you'll be doing them anyway.

Who are these women? I've found out few indicators, but I'd like you to share the ones you've found. Tipically she'll be alone, either because her friend is with someone else or she just happens to be alone. She'll be "orbiting" your group if you are doing everything right. But she won't give you the main IOI as eye contact or body looking straight to you. She'll have an open body language, half smiling, half dancing to the music. When you speak to her, she will be completely non-reactive, but you should first speak to her anyway or you'll come too strong.

An example: a friend of mine was with a woman, and her friend was with us. I was having fun with my friend and the other girl was at my left. At some point, I turned to her ear and asked "What's your name?". She told me but didn't ask for mine, so I just pushed a little bit and was like "cool" and went back to talk with my friends. But she knew my interest, she was still doing the same but I could feel how the sexual tension had just raised.

Then, while I was talking with my friends, I put my hand in her hair and turned to her and kissed her. She was really close already (IOI), so no problem. It was a "let's try it, there's nothing to loose" situation. We had some fun and then I left when I felt like it. I don't like getting too kinky if there's nothing to do for that night.

What indirect IOI have you seen on the dancefloor when there's a clear interest on not showing IOI?

Don't look for IOIs ... just assume everything.

I heard stories of Leonardo Di Caprio entering a club in Vegas only wearing a hoodie and a hat. He sits down and a HB sees him and approaches him. He then simply grabs the girls hand and takes her to his hotel. This is an example of assuming the attraction and assuming the pull. Of course he is Leo!

What I'm saying is the pro's don't look for IOIs they assume everything.

The advantage of assuming everything. Let's say you are talking about politics ... or something logical ... then you go for the make out. Even though she is not complying ... you laugh at her for over reacting ... then continue with the interaction ... then try again for the make out again ^_^. Always be applying pressure on the interaction to move forward. Example ... going for the make out even though you don't see IOI ... stare at her eyes and talk to her really close ...

Only by pushing the interaction with girls will you develop an intuition of IOIs and Windows of opportunities.

But for newbies her are some IOIs or Windows of Opportunists.

When girls are ready for a make out ... look at their eyes. If their eyes are big (aka: anime eyes) they are ready for a make out. You can even do this to a girl walking by. If you see her with big eyes ... pull her in and go for the instant make out.
Or
If you are staring at her eyes and you see her quickly look at your lips ... she want's to kiss you ...

Girls who are willing to be approached by guys
- If you see a group of girls. You see one is more energetic (dancing more) than the other girls ... she is normally easily to approached. Or the opposite ... if the group is dancing and one is not as energetic is also approachable.
- If you see girls talking to each other put have their eyes scanning the room for boys. Mostly cougars do this. They are easily to approach.

But, always be the selector! Approach all girls ...

You will only kill yourself if you look for IOIs ... You will improve way faster if you just assume attraction. Push the interaction forward by being the leader.
