Under the 2019 Rules, if a ball subsequently moves after a player has marked, lifted and replaced the the ball on the putting green, the player must always replace the ball back on its original spot.

The 2019 Rules include a new form of stroke-play called “Maximum Score” where a player or side’s score for a hole is capped at a maximum number of strokes set by the Committee

Under the 2019 Rules, there is no penalty if you accidentally move your ball or ball-marker on the putting green.

Under the 2019 Rules, when you are assessing the line for your putt, there will be no penalty if you, your caddie or partner touches the putting green to point out where you should aim.

There is no longer a penalty for hitting the flagstick that is in the hole when you’ve played your stroke from off the putting green or if you’ve played your stroke from on the green.

The term penalty area has been introduced and will replace areas previously known as water hazards.

When taking “lateral relief” from a red penalty area, under a one-stroke penalty, estimate the point on the edge of the penalty area where your ball last crossed as it went in.

When you decide your ball in a bunker is unplayable, under the 2019 Rules you have an extra option that lets you drop “back-on-the-line” outside the bunker for total penalty of two strokes.

When dropping in taking free relief or penalty relief, your ball must be dropped in and come to rest in the defined relief area.

When you drop in relief areas defined by one or two club-lengths, in the 2019 Rules, a club-length will always mean the length of the longest club in your bag, except your putter.
