There is a hazard or an obstacle blocking a clear shot to the green.
You need your ball to land on an island green.
We love it when we make the perfect shot and often expect it to happen again every time we try to repeat it. When you fail duplicate that shot it causes your game to fall apart.
If you are playing just to practice and you approach a water hazard or a tough shot, you switch to a dingy ball you found on the course. You are usually glad you did because the ball went just where you didn?t want it to go.
You have to make a shot over a water hazard or a sand bunker. Every time you approach a shot like this, you focus too much on what you do not want to do and somehow that is exactly what happens.
You are in the rough with an obstacle blocking the green. So you need to hit the ball so that it flies high and short with a soft landing.
You need to hit under trees or other obstacles and you do not want to take a penalty for an unplayable lie.
The ball is sitting in shallow water and you cannot afford adding on a stroke due to an unplayable lie.
Your ball is in or surrounded by pine needles, twigs, leaves, or dirt. Remember, you cannot move the ball without taking a penalty. If you remove anything from under the ball and it moves, you need to replace the ball and add a on a stroke before even taking the shot.
You need to hit over a water hazard. Most mistakes occur here because you do not take enough club. Players are afraid of over shooting and getting in trouble but you will have even bigger problems if you do not take a long enough club.
