This evening, Private Practice returns to ABC with another new episode, "Know When to Fold." All hell breaks loose when Charlotte's rival practice, Pacific Wellcare, opens its doors and the competition with Oceanside Wellness begins.

Check out four sneak previews below!

Sam and Pete steal one of their clients, a patient of Addison's goes to a Pacific doctor for a second opinion, and Dell proposes an in-house adoption program.

Looks like another good one! We'll have a full recap for you tomorrow after the show. For now, discuss in our Private Practice forum!
