Practice: You may not hit a practice shot while playing a hole, or from any hazard. Normally, practice is not allowed on the course before a stroke event, but is allowed before a match. However, a committee may alter this rule so always check the conditions of competition.
Always borrow money from a pessimist. He won't expect it back.
Rakes in Bunkers
Rakes are movable obstructions, so if a ball comes to rest against a rake the player may remove the rake without penalty, even if they move their ball while doing so. If the ball is moved it must be replaced and if it will not come to rest on the spot where it originally lay, it must be placed at the nearest spot, not nearer the hole, where it can be placed at rest (Rule 20-3d(ii).
Golf Australia, in their Administration manual for preparation of bunkers for elite competition, requires rakes be placed outside of bunkers.
How do you place the rake and why?
