You should NEVER twist or snap your hand when throwing any pitch, including a curveball. That increases the stress on your elbow and shoulder and leads to significant injury issues. A proper curveball is accomplished with grip and angle of the hand position during a normal throwing motion. Please refer to any book or video by Tom House on this issue
