During the point of live play the competitors take alternate strikes at the ball making the front wall the prime target. The player receiving a service may hit the ball after allowing it to bounce once on the floor or he may also choose to make a return while the ball is in flight. He must make it a point to get a direct hit on the front wall before the ball comes in contact with the floor. The IRA kicked off the first ever professional tournament in 1974 and in the same year stood out as a founding member of the International Racquetball Federation or IRF. During the latter stages of the 90s the IRA came to be known as the American Amateur Racquetball Association or AARA. Its name was then altered to USRA or the United States Racquetball Association. Players take alternating turns at service chores. Service is then received by the other two individuals who will play as a unit. California or in-and-out is also a three-player game. This involves two persons going head to head while the third competitor waits in the back court. A rally takes place with the winner coming out to serve the waiting player. Basketball has the rectangular court and the ring with backboard, golf has the green and a club, and baseball has the diamond-shaped field with a ball and bat. These games provide a breathtaking experience for both the players and the fans because their particular equipment has evolved quite well through the years. Another hinder can be caused by serious body contact which results in the prevention of a return shot. An offensive player can be awarded with a point once his opponent commits an avoidable hinder. One good example is the failure of a player to move in order to provide sufficient space for his counterpart to execute a shot straight to the front wall. A right-handed player performing a forehand to the right front corner is doing a frontside pinch while a forehand shot to the left corner can bring on a reverse pinch. A right-handed player makes a backhand frontside pinch when aiming to the left corner and a reverse double pinch when oriented towards the right corner.
