A served ball that strikes the front wall and on the rebound reaches the server so close that the receiver is unable to have a clear view is called a screen serve. There are also various forms of hinder in the game. Play is halted when the ball makes an abnormal bounce off a rough or irregular surface or when it makes contact with any portion of the court that was pre-determined as a court hinder. (You will have to torque your wrist if you want to hit the ball flat.) Another grip to head off potential problems would be placing your forefinger up the grip pointing towards the racquet face on the forehand stroke, inhibiting a wrist snap. On the backhand stroke, place your thumb on the handle as though you are pushing an imaginary button. The presence of around 40,000 handball court in YMCAs and JCCs also contributed to the game s cause. In 1969, the International Racquetball Association or IRA came into being via the efforts of Robert W. Kendler who was the president-founder of the US Handball Association. Moreover, in this very year the IRA took the spot of the NPRA in facilitating the national championships. There are court shoes that are commercially available to help players get appropriate footing on the floor of the court. Racquetball gloves are available with designs that could help players keep grip on the racquet. Such accessories would be very helpful in playing the sport well. More and more fitness clubs are offering and facilitating racquetball. Play the angle in hitting the front wall so that the returning ball will be deep in a corner. If your opponent can hit it, he might be in an awkward place at the back corner and will have trouble in the next shot. Again, returning the shots is tricky by themselves. Placing the ball where you want it needs practice. 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.
