Patrons file onto the course after the gates are opened near the first fairway before the start of the 80th Masters Golf Tournament at the Augusta National Golf Club. And of course there is the surest and fastest method of all: the use of the correct key. Other classes of attack, not discussed here but at least as worthy of study and scrutiny, include lock decoding, which is concerned with producing a working key based only on access to the external interface of the lock, lock bypass, which aims to unlatch the underlying locking mechanism without operating the lock at all, and forced entry, which, as the term suggests, involves the destructive application of force to the lock or its surroundings. Traditionally, Billiards has been a blanket term that refers to any kind of sport that involves using a cue. The pick design it calls a "rake" is called a "hook" by the rest of the world (it's the kind of pick you'll be using most). The first step toward learning to defeat locks is a thorough understanding of how they work, where their security comes from, what is billiards and how their design and manufacture introduces potentially exploitable vulnerabilities.

In this document. we focus specifically on the conventional "pin tumbler" lock, which is the most common commercial and residential design used in the United States. 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. It's binding because it's the one most out of alignment in the direction you're turning, and so its top pin is being pinched (gently) between the plug and the shell. Do not assume that the next pin will be adjacent to the one you just set. Other lock types include "European profile" cylinders, master keyed locks, master ring and SFIC cylinders, tubular pin tumbler locks, dimple-key pin tumbler locks, pin tumbler locks with secondary locking mechanisms, wafer tumbler locks, disk tumbler locks, lever tumbler locks, combination locks, and electronic locks. While some of these features can be defeated with conventional picking tools and are covered here, picking high security locks generally requires specialized tools and techniques (often designed for a specific brand or model of lock) and are beyond our scope here. A detailed introduction to locks is well beyond the scope of this document; we assume here that you already understand, or have access to, the basic principles.

Eventually, you'll be able to comfortably pick the locks with five and six pins installed. When you hold a cylinder in your hand you get different feedback from the pins than you do on a real door. If you can find a copy for sale, get it. Losing Hazard: You score if you hit the other cue ball, which should then hit the red ball and pocket the ball to get three points. The controls are easy, simply click and drag to find the right level of force, then line up the angle with the ball that seems easiest to pot next. While pins are usually set by raising the cut from the plug to the shear line, they can also be picked by first oversetting the cut to within the shell and then lowering it to the shear line. The pick must be strong enough to resist bending or breaking while lifting pins, yet the shaft must be small and thin enough to maneuver freely around the keyway without disturbing other pins.

While pin-at-a-time picking is usually the most reliable way to open a given lock (and the skills used essential for mastery of other techniques), raking can sometimes open a lock more quickly. By honing your skills and knowledge of the game, you can enjoy the thrill and excitement of billiards to the fullest. Pin-tumbler lock picking has long been among the common skills of the security community. From the attacker's perspective, too, lock picking is rarely the most efficient, most economical, fastest, or easiest method of entry. Criminals generally prefer either procuring a key or forced entry for speed, certainty, and stealth, notwithstanding whatever property damage or evidence is left behind. Surreptitious entry (e.g., for espionage or law enforcement surveillance) is likewise often best accomplished by obtaining a key or through the use of specialized decoding or bypass tools designed to quickly and quietly defeat the locks used by the target. Probably the best book I've found on picking locks is the Gerry Finch Manual of Lock Picking, which unfortunately appears to be out of print as of this writing. Often raking is used to best effect in conjunction with pin-at-a-time picking. For example, the method it calls "scrubbing" is called "raking" by almost everyone else (it's not something I suggest you spend much time on, at least at first, by the way).
