A screen, also called a pick, is a legal block set by an offensive player on the side of or behind a defender in order to free a teammate to take a shot or receive a pass or dribble past his defender.

The screen should be set stationary in such a position to delay the defender following the path of the dribbling opponent.

The effectiveness of the screen depends not only on the screener but also on the person who receives the screen. It is important that the player comes close to the player setting the screen. If he makes the mistake of going a step or two away from the screener, the screen will lose most of its effectiveness, especially when a good defensive player is guarding him.

Pick and roll

This is a combination play between the screener and his teammate with the ball. Its essence is that after the screener has set a screen, He makes a turn and looks to receive a possible pass. If it is well executed and he reecives the ball, generally he is in a very good scoring position.

This type of play is one of the most often used against the man-to-man defence.
