Bert
Also known as: doubles erne, cross-court erne
A bert is a doubles variant of the erne. A player crosses in front of their partner and jumps around the far kitchen post to hit outside the non-volley zone.
The erne requires jumping around or beside the post on your own side of the court. The bert is its doubles-specific cousin. One partner crosses entirely in front of the other to attack a ball that has drifted wide. For example, they might move from the left side to the right-side post. Because the bert requires crossing the full width of the court, it demands exceptional communication and commitment from both partners. The partner who stays must cover the entire vacated half of the court, and both must call the maneuver in advance. When executed cleanly, it is one of the most spectacular plays in doubles pickleball.
The bert requires an even higher level of partner trust than the erne, because one player crosses in front of the other. That physical commitment temporarily removes both players from their assigned side. The staying partner must resist the instinct to move toward the ball. Instead, they hold the vacated side firmly, trusting that the bert player will complete the play. Any hesitation by the staying partner creates a gap that an alert opponent can exploit down the line.
The bert is most viable when the ball has drifted wide to the side opposite the bert player. Pulling them across the court then creates a genuine angle advantage, not just a spectacular movement. When the bert player reaches the post, they must make contact outside the kitchen zone and land outside the kitchen after contact. The landing zone is the most commonly missed rule in bert attempts. Players who leap across the court sometimes land inside the kitchen, causing a fault even if the shot was a winner.
Master the standard erne before attempting the bert. The bert adds partner coordination to an already complex overhead contact, and executing it without erne experience creates confusion rather than opportunity.
Call the bert to your partner before you start moving — not as you cross in front of them — giving them the maximum time to cover the vacated side and ensuring neither of you hesitates.
Example
The left-side player sprints across the court in front of their partner and contacts a wide ball outside the right post. An aggressive bert — while the partner covers the left.
How it shows up on video
On video, watch the bert player's movement across the court. Pause at contact to check it against the kitchen boundary. Also watch the partner's position during the crossing for coverage gaps.
Common mistakes
- The staying partner moving toward the bert player's target rather than covering the vacated side
- Contacting the ball while any part of the body is inside the kitchen zone, causing a NVZ fault
- Attempting the bert on a ball that is not wide enough to create an angle advantage, producing a speculative play with no tactical gain
- Not communicating the bert attempt before crossing, causing the partner to also move and leaving the whole court uncovered

Motion Lab follows one athlete and does not track court distance, your partner, or the NVZ boundary. On video, check how far the bert player crossed and whether the partner shifted to keep full court coverage. Also check contact against the NVZ boundary.
