Playing stroke, David and Greg are both on the putting green.
Greg's very errant putt looks like it might strike a player's glove that has (earlier) been left on the putting green which might affect where his ball could come to rest
Whilst Greg's ball is in motion, Greg instructs David to lift the glove to prevent any such interference, which he duly does as he agrees that a strike is imminent.
If David had not lifted his glove, Greg's ball would have most likely struck the glove.
Both players get a 2-stroke penalty.        [REF: 4S1532]

Playing stroke, Liz's tee stroke has come to rest in an abnormal course condition No Play Zone.
She plays a poor stroke from that position, which stays in the NPZ.
From there she now plays to the putting green.
Liz's next stroke will be her fifth.     [REF: 4S1544]

Playing stroke, Greg's tee stroke might be lost (on the course, outside a penalty area) so he declares and plays a provisional ball.
Greg finds a ball that he believes is his original in a playable position (on the course), makes a stroke at it, lifts the provisional ball, and then discovers that the ball he played was not his original ball.
Greg resumes searching for the original ball but cannot find it within the time allowed.
If Greg returns to the teeing area, his next stroke will be his ninth.    [REF: 4S1482]

In a stroke round, David's ball is at rest on the putting green after 3 strokes.
His next stroke is strong and comes to rest in a yellow penalty area situated well below the other side of the putting green.
David best estimates the point of entry and drops a ball into a 2-clublength lateral relief area.
Before making a stroke, he lifts the ball and places a different ball on the spot from where his putt was made from.
From there, David holes out with 2 more strokes.
David scores 7 for the hole.       [REF: 4S1508]

David and Greg are about to start their stroke round.
They are waiting on the first tee for the players ahead to play their second strokes.
Greg asks David what club he intends to use and David replies with "I'm going to use my 4-iron given the windy conditions".
There is no penalty to either player.     [REF: 4S1458]

Greg is playing stroke and has 14 clubs in his bag.
Having a bad day on the putting green, in frustration, Greg snaps his putter shaft, making the club non-conforming.
Later in the round, his sand-wedge is accidentally damaged when a maintenance vehicle runs over it.
Greg quickly runs into the nearby locker room, drops off his damaged sand-wedge and grabs another putter.
Greg uses the added putter for the remainder of the round (instead of his damaged putter).
Greg is disqualified.     [REF: 4S1477]
