The 4-2 offensive is the first volleyball offense to be discussed. This translates to four hitters and two setters on the court. The two setters will play opposite one other and set when they are on the front row, leaving two hitters on the front row at all times. This form of offense is not without its drawbacks. Most notably, it is difficult to replace players due to the number of positions that need to be filled. However, if you have the resources available, this form of attack can be effective. Hitting takes place at the net or in the middle. There are three main types of swings used by the hitter: topspin, backspin, and flat. Each type of swing has its advantages and disadvantages. For example, a topspin shot is harder to block than a flat because it stays on the floor longer. However, a topspin shot travels less far than a flat so you need more of them to hit well. Backspin is used for hitting down the line or into the corners. Because it goes around the side of the net, a backspin shot is easier to return than a topspin or flat shot. After hitting, the ball will come to rest under one of three conditions: out of bounds, in the receiver's hand, or on the floor. If the ball is out of bounds, there is no point value for that ball and the game continues as normal. If the ball is in the receiver's hand, it is a free ball.
