 An exception occurs when the interfering player is directly in the path of the other player's swing, effectively preventing the swing, in which case a stroke is always awarded.When it is deemed that there has been little or no interference, the rules provide that no let is to be allowed in the interests of continuity of play and the discouraging of spurious appeals for lets.Because of the subjectivity in interpreting the nature and magnitude of interference, awarding (or withholding) of lets and strokes is often controversial.
