Perfect time to show her the new man you've become with your gaming skills!
As she is an old friend though, I would say you should stay away from emotional connection shit, and get more into demonstrating your value, teasing her a bit and being brave with kino - hand on the lower back to push her towards the bar, holding her hand to lead her places etc etc. (that's just my opinion though)
Also, buy her a drink. I mean, make a show of it - she will probably say 'no, no, i'll get them' blah blah blah, say no and go macho. I know all the books say don't do it, but you wanna let her know that she is on a date with you? Buy her a drink, and if you're both sat there with empty glasses and she's looking around waiting for you to get her a drink - then waggle your glass in front of her and say 'your turn' with a big grin on your face
Alternatively she may offer to buy you one, and you say no, no I'll get them, if she's a normal human female she will then insist - you give in and get your drink bought for you, whilst at the same time looking macho and like a perfect gentleman. Move conversation onto relationships and sex quickly, get her thinking about it, with you. that with escalated kino, and a few drinks - i think you'll be good to make a move.
