An opener is exactly the same thing as an opening move in chess.
You can move any one of your pawns down the board, you can bring your knight in to play but, sure as eggs are eggs, NEITHER opening move is guaranteed to win you the game - it's what you do after, and the mindset you bring to the game, that is the key.
Lets look at your options:
1) You can open indirect ("Where's the nearest Starbucks?"), and talk in a mealy-mouthed, beat around the bush type of way, just hoping she is going to show enough interest in you that you will eventually be able to pluck up enough courage to articulate your intentions towards her.
- WEAK SAUCE -
2) You can open indirect (as above), but laser-eye-fuck the living daylights out of her as you talk about your love for peppermint hot chocolate, thus pumping her buying temperature. and leaving her in no doubt that you want to fingerblast her behind a dumpster. I am now in such a place in my head that I believe, when I laser-eye-fuck a girl, her pussy starts to tingle and get wet; it's a self-fulfilling prophecy.
- THIS IS GOOD, ESPECIALLY IF YOU'RE UNCOMFORTABLE HITTING ON GIRLS VERBALLY WITHIN EARSHOT OF OTHERS. AND WHAT DO THEY SAY? 97% OF COMMUNICATION IS SUBCOMMUNICATED, ANYWAY.
3) You can open indirect, then in the very next sentence admit why you're talking to her.
"Hey, where did you get that hat from? My niece would love one like that for her birthday."
"Actually, I haven't even got a niece. I just had to talk to you because I saw you and thought you were striking"
(Just a note: I'd never use the word: 'cute' - teddy bears and babies are cute. 'Nice' to me, is too wishy-washy, as well. If somebody described ME as 'nice', I'd take it as an insult)
- ON ANOTHER FORUM THIS TYPE OF APPROACH IS KNOWN AS: DDA (DELAYED DIRECT APPROACH), AND PEOPLE HAVE HAD SUCCESS WITH IT.
4) A balls-out, no nonsense super-direct approach - both verbalizing and subcommunicating your desire for sex with this girl.
- THIS IS VERY POLARIZING AND NOT VERY BEAUTIFUL OR SUBTLE. *HOWEVER*, IT SAVES YOU A LOT OF TIME AS YOU FIND OUT ALMOST IMMEDIATELY WHICH GIRLS ARE DTF.
However, as I said, it is not the the opener that gets you laid, it's what you bring with it to the interaction: the energy, the fun, the sexual tension, the romance, the honesty etc.
Remember, an opener is just that: The opening sentence to a conversation - nothing more, nothing less. You can use the most laser-intense, super-direct opener ever known to man but, if in the following conversation, the girl picks up you're a needy, whiny, value-taking, little bitch, your opener will count for nothing.
I'm all about honesty, being a man, and being unapologetic that I have a dick and I want to use it on her. I've no time for manipulation, button-pushing, or micro-managing my behaviour as to what I think the girl would like to hear.
So, choose your weapon. What's your poison?
