Player Positioning
Besides the server, there are no rules dictating where each player must stand when the serve is initiated, but serve receivers usually start behind the baseline until they know where the serve will bounce. The receiver's partner usually starts near the non-volley line also known as the kitchen line. The server's partner usually stays behind the baseline with the server until they know where the first service return will bounce. Some doubles partners use a strategy called stacking to ensure each partner can quickly move to the most advantageous side of the court, based on each partner's skill set, after each serve and/or service return.
Serving from the wrong side of the court, the wrong player serving or the wrong player returning a serve should be avoided. Though not a fault since USA Pickleball changed the rule in 2024, player positions should be corrected as soon as they are noticed. If noticed during a rally, the rally should be stopped and restarted. If noticed after the rally is finished, the rally stands.
Singles: In singles, a server's score will always be even (0, 2, 4, 6, 8, 10...) when serving from the right service court and odd (1, 3, 5, 7, 9...) when serving from the left service court.
