"All I need is a partner to play spades with the cards up, All trust!"
- Jay Z

You know what.. It makes a hell of a lot more sense now.

There's a lot of people who think they can play spades. Spades can be as sensual as a relationship (or jus sex). It's a team game.
If you think u can run 8 books... Either it goes three ways.

You think your teammate can't cover you, so you sell yourself short and say you have a 5, because you gotta cover your partner's stupidity, because you dont ever know what they're thinking , and how they operate.. the learning stages.. dont you hate when you get stuck with a partner who thinks they can play, and then there's just no connection there. It's gotta be a relationship.
or...

You go 8, and when you go eight, your partner knows what's up. they know what you mean when you say eight.. they know how you go about making your books (do you lead off with spades... do you talk when you got a good hand, can you see thru the bluff...) just tendencies that make a good team a good team. Does the partner pay attention when you play off of her ace of hearts, does she go back to it , and put the TEAM in a better position to come out on top.

or...

You take over, because you think that your hand is just that good. You have the top spades, all the high cards in every suit... and you know you can get in with any off suit. You cut over your teammate, you do what you want to do. and that's ok for the time being... until you dont have a bangin ass hand... and you can't operate any way else.

With that said.. that's all just a big ass metaphor for relationships.

needless to say.. i need a woman who knows how to play spades. forreal.
