TheSniper said:More often than not I go down to the pool hall by myself and find there's no one to play against. Fair enough. I'll just play by myself. So I throw 9 balls out on the table over and over and run them out. This can't be the best way to improve my game. Could someone tell or show me some good drills or practise routines to go through when I'm at the pool hall by myself.
I agree with Hal that you need to rack them up and break instead of throwing them out. I know it's inconvenient to rack, but breaking well takes a lot of practice, and you'll end up with more game-like ball positions/clusters to practice.
I think practicing like this can be very effective, especially if you stop whenever you make a bad mistake (miss a ball, hook yourself, scratch, etc.) and practice the shot you messed up until you can execute it correctly several times in a row. I've heard multiple great players say that this is their primary practice method.
Once you've identified weaknessed in your game by doing this, you should figure out/search for drills that target these weaknesses. I don't think there's any complicated formula for how to improve. Practice playing the game, and take time out to target your weaknesses. If you suspect you have mechanical issues that hold you back, find an instructor who's qualified to help you correct them.
