One of the white balls (plain or spot) serves as the cue ball for each player, the red ball and other white ball serving as his object balls. There are three ways of scoring: (1) the losing hazard, or loser, is a stroke in which the striker’s cue ball is pocketed after contact with another ball; (2) the winning hazard, or pot, is a stroke in which a ball other than the striker’s cue ball is pocketed after contact with another ball; (3) the cannon, or carom, is a scoring sequence in which the striker’s cue ball contacts the two other balls successively or simultaneously. The player must first pocket a red ball and then try to pocket any colour he may choose, scoring the value of the ball that he has pocketed. He then alternately pockets red and coloured balls. It is worth noting that the laws of physics that determine how the billiard balls move are precise and unambiguous: they allow no room for randomness. In play, the object is to stroke the cue ball so that it hits the two object balls in succession, scoring a carom, or billiard, which counts one point.
Notice that three points are aligned: the point marking your position, the point on the mirror where you see the reflection of the object and the (imaginary) point behind the mirror where you believe the object to be. The traditional mahogany billiards table is still in use, but tables are now generally made of other woods and synthetic materials. 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). There are many different styles of raking, some of which entail the use of special rake picks specifically designed for a particular technique. Become comfortable with this before you try picking this lock with torque or you could bend or break your picks. No matter how consistent you are with the first shot (the break), the smallest of differences in the speed and angle with which you strike the white ball will cause the pack of billiards to scatter in wildly different directions every time.
What at first glance appears to be random behaviour is completely deterministic - it only seems random because imperceptible changes are making all the difference. The pins are at the bottom of the keyway rather than the top. 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. Snap guns are occasionally successful as well. These locks are unusual in not requiring springs on the individual tumblers and are therefore especially well suited to outdoor use under extreme conditions. India, they are commonly used for door locks and padlocks as well. While the pin tumbler cylinder is by far the most popular door locking mechanism in the United States, it is not the only kind of keyed lock in common use. The most comprehensive treatment of raking techniques I've found is in the Finch Manual of Lock Picking, what is billiards although other authors have different perspectives on the subject.
These locks are often quite susceptible to rubbing and jiggle-key raking. Interestingly, what we get is an elliptical caustic curve that shares the same foci as the elliptical table, and so these are confocal ellipses. What if we change things slightly and have the ball initially pass between the two foci? While looking at an object in a mirror, you have the impression that the object is behind the mirror. You can challenge the clock and compete against other swimmers in this state-of-the-art swimming facility while you swim laps by yourself in the pool. Now release torque and start over, taking care to pick all the pin stacks with spool/mushroom pins while leaving at least one regular pin stack unset (this will require a light touch and good sensitivity). Now is the time to demonstrate what you're capable of. You should always know which pin you're working on at any given time. Gradually ease up on the torque, allowing pins to drop one at a time. For example, Medeco locks use special wedge-shaped bottom pins that are rotated into one of several possible positions by the key cuts (which can be cut at different angles).
