The old double-hit

There is no longer a penalty for hitting a ball multiple times on the same swing. The old rules stated that if a player swung and hit the ball more than once (most common on chips and pitches), the player had to count the stroke and take a penalty stroke.

Under the new rules, if a player hits the ball more than once, the player just counts the intended shot and plays the ball from where it came to rest.
