You need to be familiar with the rules before you can start playing bar-pool. You should know the rules of 8-ball, Rotation and Double tapping as well as Assigning solids and stripes. This will ensure everyone enjoys the game. This will allow you to win.
8-ball
Eight-ball pool rules differ from the rules for professional pool games. The 8-ball pool rules are meant for the average player, not the professional. These rules won't force you to learn 15 pages of complicated rules just to play a particular game. Instead, the rules will help you understand how to play basic pool.
Color-based racking is not allowed in the eight-ball game. The 8 ball must be the first of the three middle balls in this game. Most people prefer to place the one in front. Rules also stipulate that you can lose a turn for making a mistake with a ball. It is also not a requirement to call straight shots or touch a rail when making a shot.

Double tapping
Double tapping in bar pool rules refers to a player's ability to double tap on an object ball by positioning the cue ball close to the object ball and aiming at it. A cueball is closer to an object when it is less then an inch from it. It is also called "sharking".
Assigning solids to stripes
It is common to assign solids or stripes for bar pool rules. This helps define the game's style. The most common pool games are solids and stripes, which are variations of eight ball. In a game of 8 ball, players use a cue ball to call most aspects of a shot.
Official pool rules prohibit hitting an opponent's object ball first. The turn ends when a player has taken a striped object ball. Double hits are when the cue stick strikes the cueball twice in one stroke. This is called a foul.
Etiquette
There are many rules to play pool at a bar. Each bar will have their own rules. Be sure to check before you go. You might also ask about any special rules in effect for the next games. If there are any, it's best to respect those rules and play by them. Everyone can still have fun with the game and not do any damage.

It is important that you remember that WPA's "official rules" don't include "dirty swimming pools." Smart pool is the type of shot that's not dirty. However, some people consider defensive shots dirty. Intentionally scratched shots are also considered unethical.
