I have a nice spin move i do, not to fancy but it get you an open shot and a lil reaction. Most importantly its legal. I dont have a name for it though.

Say your posted on the block with your defender right behind you.

1.While dribbling the ball in your right hand give him a shoulder fake to the right.
2. then quickly go to the left pivoting on your left foot, making him think you are going to try and go around him, then immediately change directions by crossing the ball over to your left hand, (making him think u are now going for the layup on the other side of him)
3.then immediately spin back to your right (the opposite direction) picking up your dribble and using your 2 steps to roll right around him.

This move should be done very fast and very close to the defender. If you pull it off correctly the defender will left completely on your left side not even facing you at which point you can layup or dunk.
