Adjust your play
You need to adjust your play depending on the pocket size. If the pockets are really tight, you need to be more careful. Some pockets have jaws that are really sharp and very difficult for you to get the cue ball inside. These pockets do not accept side so easily and the cue ball will rebound out of the pocket unless you get right inside the pocket.
The run through loser is a good example of a shot that is valuable on a tight table. A pot along the cushion may not be a sensible option but by using side on a run through loser, the pocket effectively becomes bigger.
