Note that while many locks pick predominantly back to front or front to back, there are exceptions, and you may find that the binding pin stack "jumps around" from the back to the front to the middle and so on. You may hear a faint "click." This is because you've pushed the cut (between the bottom and the top pin) up to exactly the shear line. While this might have gotten the lock open, you just as easily might have pushed the cut past the shear line entirely, preventing the lock from opening altogether. If you're having trouble, you may be pushing adjacent pins up past the shear line as you pick a pin, causing them to be overset even before they start to bind. If you inadvertently push a pin up too far or are applying so much torque that more than one pin is binding, you may have an overset pin instead. You should already be able to distinguish between an unset pin that isn't binding, an already set pin, and a pin that is binding.

Now the plug is being prevented from moving by the next most misaligned pin (which, in this case, is the other pin, since there are only two). The pin is not picked but is not the currently most misaligned one. Once you've picked a cylinder, you should know in exactly what order the pins pick. Learn to pick this lock one pin at a time. Some lock manufacturers and locksmiths install special "security pins" intended to resist lock picking. Many dimple key locks also incorporate secondary high security locking mechanisms. Most wafer locks are made to very loose tolerances and have relatively open keyways, however, and are very easy to pick. Chances are the two pins will be reversed -- the formerly springy one will give resistance and the formerly stuck one will be springy. This will overset the pin. Much of lock picking skill depends on testing pins stacks for the purpose of finding which to push up next and assuring that no pins are overset. Congratulations, what is billiards you've picked the (two pin) lock. Set/not-binding. The pin stack was already picked.

A pin stack in a lock being picked might be in any of four states: Unset/not-binding. Each of these sports focuses on the idea of hitting small balls with the end of a narrow stick called a cue with the object being to accrue more points than the opponent. This technique requires a great deal of practice to master, but has the surprising property of sometimes being more effective against better made locks. Eventually, you'll be able to comfortably pick the locks with five and six pins installed. These are typically pin tumbler locks, but their orientation is "upside down" with respect to the convention for locks installed in the United States. Again, continue with the AR1 locks. Now release torque and try again, but this time lift the pins as little as you can when you test them, while still distinguishing between the two states. You should always know which pin you're working on at any given time. Only one pin stack should be in a binding state at any given time, of course. Unset/binding. The pin stack is the currently most misaligned one. Your goal is to learn to do this with the absolute minimum amount of torque needed to bind the most misaligned pin enough to distinguish it from the other one.

If both feel springy, you're not applying enough torque (which is unlikely). Now re-apply torque and set the first binding pin. It's possible that the plug will turn as soon as you set the first pin; if this happens, it's because you inadvertently lifted the other pin with the shaft of your pick while you were working on the first one. To win the pool game, you will need to pocket the number 8 ball after you have pocketed all seven balls. As long as a shot first contacts the lowest ball, any ball pocketed allows the player to continue shooting. The difficulty he has arises out of Astill’s managing to avoid much in the way of controversy over his career and, playing for arguably the least "fashionable" of the First Class counties, not having participated in any famous matches. Observe that after you set the first pin, your three pin cylinder has one pin in each of three different states: set/not-binding, unset/not-binding, and unset/binding.
