I went out last night with some of my friends, 4 guys (2 alpha type, two beta) and a girl. We all hang out fairly regularly. We were at a bar, sitting outside together. I want to know, how should I act to maximize attraction with the one girl? She has some baseline attraction towards me (laughs at my jokes, gets me into conversations with her etc). Should I focus on talking and joking around with the alphas, or talk primarily with the girl?

Remember I want to know what to do for this particular situation, not overall.
