The balls used are smaller and the table is pocketed. Straight pool is played to a specific number of points agreed on prior to the match's start, with each pocketed ball being worth one point to the shooter. It is played using a cue stick, one white ball (the cue ball), fifteen red balls and six colours: a yellow (worth two points), green (three points), brown (four points), blue (five points), pink (six points) and black ball (seven points). The rules also vary depending on whether the cue ball or fifteenth ball are resting on the table's head spot. Play then continues with the cue ball shot from where it rested and the fifteenth ball from where it rested prior to racking. A number of rules have developed which detail what must be done when one or both of the cue ball and fifteenth object ball are either in the rack area at the time an intragame rack is necessary, or are in such close proximity to the intragame racking area, that the physical rack cannot be used without moving the one or the other. After the initial rack, the balls are played until only the cue ball and one object ball remain on the table's surface.
If you don’t have a way to set up your next shot, you can always position the cue ball to make things harder for your opponent. In nine-ball, the basic principles are the same as detailed in the eight-ball section above, but only balls 1 through 9 are used; the 1 ball is always placed at the rack's apex (because in nine-ball every legal shot, including the break, must strike the lowest numbered ball first) over the table's foot spot, and the 9 ball is placed in the center of the rack. In both one-pocket and bank pool all fifteen object balls are racked entirely at random, with the center of the apex ball placed directly over the foot spot. But there are other easy ways to tell what type of material is used on any given pool table. In nine-ball games where a handicap is given by one player being spotted a ball, some tournament venues enforce a rule that the spotted ball must be racked as one of the two balls in the row directly behind the 1 ball. The 8 ball must be in the center of the rack (the second ball in the three-balls-wide row).
On the baulk line, looking up the table from the 'baulk end', the yellow ball is located where the "D" meets the line on the right, the green ball where the "D" meets the line on the left, and the brown ball in the middle of the line. Some players (most often amateurs) place the balls in numeric order but for the 9 ball; from the top of the triangle down and from left to right, i.e., the 1 on the foot spot, followed by the 2 then 3 in the second row, and so on. If there is no available spot, it is placed as close to its own spot as possible in a direct line between that spot and the top (black end) cushion, without touching another ball. If there is no room this side of the spot, it will be placed as close to the spot as possible in a straight line towards the bottom cushion, without touching another ball. Erring too much in this direction is "missing on the professional side of the pocket." It is so called because experienced players understand that on a thin cut, overcutting the object ball to a corner pocket will far more often leave the object ball in an unfavorable position, i.e. along the short rail for the incoming opponent than will an undercut, which often leaves the object ball sitting in front of or nearby the pocket it had been intended for on a miss.
A semicircle of radius 11.5 inches, called the "D", is drawn behind this line, centred on the middle of the line. At the exact middle of the table sits the blue ball. Finally, the black ball is placed on a spot 12.75 inches from the top cushion on a full-size table. Every four years, the top countries play in the World Team Championships in AC (the MacRobertson Shield) and GC (the Openshaw Shield). Nitrocellulose lacquer is spin-coated onto aluminium or glass discs, then a groove is cut with a lathe, to make one-off phonograph records, used as masters for pressing or for play in dance clubs. A nitrocellulose slide, nitrocellulose membrane, or nitrocellulose paper is a sticky membrane used for immobilizing nucleic acids in southern blots and northern blots. A few years later in 1838, another French chemist, Théophile-Jules Pelouze (teacher of Ascanio Sobrero and Alfred Nobel), treated paper and cardboard in the same way. Around 1846 Christian Friedrich Schönbein, a German-Swiss chemist, discovered a more practical formulation.
