Understand the ruling
A ball went in, but the turn ended. Or the eight dropped and the rack was lost. Start with the rule surprises that cause the most confusion when switching from another pool game.
Control what happens after the pot
Draw, follow and stun describe different cue-ball outcomes. Learn why contact point alone does not decide the result, and compare shots without changing all your settings at once.
Plan a small route through the table
Good position is often a generous landing area, not an exact spot. Work backwards from a third ball and choose a first shot that keeps useful options open.
