Go to top/bot where enemy isn't hugging turret (around middle of the lane, at least)
Enjoy free kills/pressure
Playing in lane heavily depends on champion you play, and the matchup. In general it's better to play aggressively, or passive-aggressive. Laning is also really damn wide topic, and i don't wanna write a wall of text. You can always watch Annie Bot if you wanna see how to play her.
if you play annie try to save up your passive and bait them to your turret .aboout roaming ,check to see if your laner is there or not go to botlane/toplane just wathc out for your leaner returning to lane . cuz if you do it wrong you might lose a tower
