I’ll be playing in my first ever APA Cities this weekend in 9 ball.
Anyone got advice for a first-timer? It’s at a pool room I’ve never played at before, so I definitely plan on practicing there a couple times this week to get a feel for the tables and speed.
Don't worry about your opponent, their skills are irrelevant when you're shooting. Shoot the percentages, if you're on a ball you have a 80-90% chance of making then don't shoot it, play a safe. The percentage is your call

Play the table, not your opponent.
