Splitting the post is one of my favourites, if it works it gives great satisfaction when you are the post.
It starts with a pass from 1 to 3.
1 and 2 will start a cutting move at the same time. As with the scissors timing is very important.
While protecting the ball 3 can make a pivot move to set a screen for 2 and 1.
1 and 2 split the post by cutting towards 3.
If 1 or 2 can grab the ball out of the hands of 3 they should do so.
The post however should not give a little hand off pass. Little control and quick defenders make this a not so smart move.
While player 3 pivots to face the basket (watch your pivot foot), 1 and 2 cut to the basket.
Player 3 has three options.
1) pass the ball to 1
2) pass the ball to 2
3) take a shot.
In this case the ball goes to 1 who makes the lay-up.
