I'm finding I do best at letting the HB's open me. I dress in such a way that I will clearly be the best dressed guy in the place. I include a bright but classy necktie (usually Jerry Garcia) for my peacock accessory. I smile all the time and brighten the smile when I make eye contact with a target. If i get a genuine smile back i just pass right on by unless they stop me. Usually they will blurt out "nice tie". at that point I thank them for the compliment verbally and with Kino (gentle hand shake if they are seated or a quick playfull hug if they are standing). Then I go into finding out who is who. if i dont get stopped I mill about through the crowd as if I'm looking for someone. After making eye contact with everyone I am interested in I sit near but not next to one of the targets and ignore all of them while I make sure they see me looking at other women (no one I got an ioi from). I always try to choose a location where everyone has to pass by, like near the restrooms or near the service area of the bar. This gives them a reason to come by. The closest target will usually open me at this point. Then I watch my peripheral vision for when the others will pass by. They will soon need to come by and open me.
