The Spin Move is a great one... easy to use and easy to learn. Plus, you don't even have to be super close to the basket to pull this one off. The tricky part is that it only works in a one-on-one situation, so you have to set things up just right, and have your power forward or center backed up against the defender. Once you're one-on-one with your opponent, simply flick the right stick to the left or to the right (depending on which direction you want your player to spin towards the basket). It's a risky move, but you know what they say about risks and rewards. Besides, when it works, it's worth it – you get past your man, you will score every time.
Another move that is mandatory to master is the Fake Shot. Why, you ask, aside from the fact that it's ridiculously simple? Mastery of the Fake can add a couple of quick baskets to your score. And when you're playing here for those high stakes, and the game is close, well, a couple points can mean the difference between winning and going home empty-handed (and empty-bank accounted). Anyway, to do this one, Xbox users, just lightly tap B (PS3 users hit the Circle button). Use it to get to the basket for a layup, or just to get an open shot. It's such a cool move, because it's so simple and yet at the same time, can dramatically tip the scales in your favor.
So yeah, don't sweat if you haven't nailed all the complex moves. Sometimes all it takes is the light tap of a button to separate the winners from the LOSERS!
