Yes, you may do so, the key distinction that you have made in the question is the ball 'out' of the bunker. If the ball is still in the bunker you would be penalised two shots for grounding a club in a hazard. If the ball is no longer in the bunker you are in you may ground the club, but be aware, there is really no need to.
yes, you can ground the club before you tee off the only time you can not ground your club is if you are in a bunker or hazard.
yes.
we believe that when in any hazard you are not allowed to groound your club and if you want to play the ball out of a hazard you are not allowed to touch any of the grass that grows in the hazard on your backswing
Yes, if a bunker is marked GUR you are entitled to a free drop. To do so, you remove your ball from the bunker, and from the nearest point of relief you are allowed one club length, you drop your ball and play. If there is water in the bunker and there is no GUR marked you are allowed a free drop in the bunker, no nearer the hole. If you cannot get relief from the water you can either play it or you can take a penalty drop out of the bunker.
No, you are not allowed to do so, you must not rake the bunker or smooth sand over with your feet, as this is deemed to be improved your stance or testing the ground conditions. You will get a two shot penalty for testing, if you do so.
It is a strategically placed and shaped hole in the ground which is filled usually with sand. You cannot ground your club in it. G1Golf.com says: It is not really a hole in the ground. It is a sand-filled depression in the ground, which, if your ball does into it, it is difficult to get out of. As the above answer correctly states, a player is not allowed to place their club into the sand, prior to hitting the ball. The technique to get the ball out of a bunker is to imagine that the ball is the yolk of a fried egg, and with the club (called a sand wedge), you try to slice up the entire "fried egg", meaning that you actually hit the sand in front of the ball, and not the ball itself. It is too difficult to describe actually! It is worth mention for golfers planning on playing in Russia, that the word 'bunker' there is extremely rude. It is a crude reference to the female genitalia.
I am not sure I understand the question in regards to the grass. If the first one is marked ground under repair you are entitled to relief, of one club length. The other one must be played as it lies, if this means the ball is in the bunker, you must not ground the club whether there sand or not.
No, this is not possible. Well, you can do it but you will receive a penalty for grounding your club in the hazard. There is no space in the rules for such an allowance which would no doubt be abused by many players.
When you 'ground' your club you have caused your golf club to come in contact with the ground or another substance such as water, sand or weeds. Generally speaking the subject of grounding a club centres around hazards where you are not permitted to touch the surface or the weeds that exist within an area marked as a hazard. If a player grounds their club in any of these examples they are penalized two strokes for doing so. If a player grounds their club on the putting surface and the ball moves - by gravity, wind or anything else - there is a penalty for this as well.
Yes, absolutely. Each bunker is considered an individual hazard, not a collective hazard of bunkers. If you play out of one bunker and land in another, you may rake the one you have just played from. Note, there is a common misconception that if you are in a bunker and rake footprints before you play your shot you are penalised, this is not the case, you are only penalised if you improve the lie of the ball, your stance or test ground conditions.
The bunker buster bomb is a very large bomb that either blows up the bunker by exploding directly on top of it (if the bunker is at ground level), Or if the bunker is a few feet below ground, the bomb will go through the dirt and explode in the general area of the bunker and destroy it. The bunker bombs of today, that are dropped by the F-15E Eagle, are much more powerful than the bunker buster bombs that were dropped in WWII by the English Avro Lancaster bomber.
