Spend more time on this exercise than you think you need to; most people never learn to properly apply the light touch needed to pick better quality locks. If necessary for the shot, the referee or a deputy may hold the light fixture out of the way. You should be able to confidently find each pin and push it all the way up, without jamming the pick against anything or moving other pins. Using the five or six pin lock, find a pick that lets you locate and lift each pin across its full range of motion without disturbing adjacent pins too much. Although the objective varies depending on the game, however, the primary goal is to pocket the balls using strategic shots. When you feel confident visualizing and using picks to maneuver around the pins in the AR1 and SX keyways, you're ready to start actually opening locks. Find the board with the six "Arrow AR1" keyway locks.

On the grid below, click on each sortable category to find out how our 60 sports rank in each skill. A process out of a thing? The player or team pocketing their group of object balls and legally pocketing the black ball wins the game. A player is allowed to ask for a reconsideration of a factual decision by the referee only one time. If the player wants to protest against that ruling, he may contact the head referee and after that the tournament director. If the interference had no effect on the shot, the referee will restore the disturbed balls and play will continue. The red balls are worth one point each, while the yellow is worth two, the green three, the brown four, the blue five, the pink six, and the black seven. The yellow, green, brown, blue, pink and black snooker balls, each worth a different number of points, are all placed in a specific position on the table.

The number of balls used in pool range from one to fifteen depending on the game type. This keyway is common in commercial and residential locks in the US, and is close in shape and size to a number of other common keyways, including that used by Kwikset, a very popular (and easily defeated) line of US residential locks. You'll notice that it resists more than it did in the previous exercise because its top pin is pinched between the plug and the shell at the shear line by the torque you're applying. It won't turn, of course, what is billiards because the cut of the (single) pin stack is still below the shear line and its top pin is preventing the plug from rotating. Several positions are possible; here a vertically-oriented torque tool is used at the top of the keyway. Your index and middle fingers should be touching the edge of the pick close to where it enters the keyway. Figure 3. Holding a pick. Figure 4. Manipulating pins. It is important to develop a "mental image" of the internal state of the lock, the locations of the pins and your pick, etc, as you manipulate the pins.

Continue with the one pin lock, trying to apply less and less torque each time. That means being able to reliably pick the lock, both clockwise and counterclockwise, and being confident that you know how you opened it. Some locks will open both clockwise and counterclockwise, but many will only open when turned a particular way, depending on the configuration of the underlying locking mechanism. See Figures 3 and 4. Once you're comfortable with the AR1 keyway, move on to the "Ilco SX" keyway locks and repeat the exercise. This keyway is a bit more "open" (it's intended to allow several different key profiles to fit in it), and so requires the use of a larger pick than the Arrow AR1 keyway does. Go back to the "Arrow AR1" keyway lock board and find the one pin lock. In lock picking terminology, we say that the pin statck is binding. The numbers on the front of the practice locks indicate the keying codes, from the front-most pin stack to the rear-most.
