Who's Puzzle?

Tip:

Shooting is a perishable skill that requires continuous work to stay sharp. But how do we stay sharp for the unexpected?

Someone else's puzzle:

When training, we need to recognize that we are attempting to solve a problem that you have never encountered. To train to this end, going to courses that force you to shoot to a standard with which you are unfamiliar is an important challenge. I attempt to attend 2 or more shooting courses per year, as well as shooting in local competitions. Both events will offer you something that cannot be found when training alone: you are shooting someone else's problem.
