堆叠站位（Stacking）
堆叠站位是一种双打策略，双方球员在发球或接发球之前站在场地的同一侧，随后在球开始比赛后滑向各自偏好的一侧——凌驾于比分决定的站位之上，让双方的正手都能覆盖中路。
在标准的双打匹克球中，比分决定哪名球员从哪一侧发球，但计分规则对球发出之后每名球员应该站在哪里并没有任何规定。堆叠站位正是利用了这一点，让双方球员在发球（或接发球）之前都站在场地的同一半，随后在球离开发球方球拍的瞬间切换到各自偏好的一侧。结果是，无论计分规则原本会把双方安排到哪一侧，双方球员在每次回合的预备阶段结束时，都能处于各自的最佳位置。
最常见的堆叠目标，是让双方的正手都覆盖中路。中路是双打匹克球中来球最多的区域，而中路的正手比反手拥有更好的角度和更大的够球范围。对一支双方都是右打的组合而言，这意味着双方都想站在各自的右侧位置——左侧球员站左边，右侧球员站右边——这样他们的正手就能自然覆盖中路。当计分把一名球员轮换到本应是其反手覆盖中路的一侧时，这支组合就会通过堆叠来纠正它。对一支左右手混合的组合而言，站位目标可能有所不同（是保护某一方球员的弱点，而不是最大化中路正手覆盖）。
完全堆叠意味着双方球员在每一次发球时都堆叠并切换。半堆叠意味着只有一种轮换（仅在发球时或仅在接发球时）使用堆叠。这次切换必须在发球之后、回球到达之前干净利落地迅速完成——缓慢的切换会在覆盖上留下一个临时空档，一支反应敏锐的接球组合能用一记直线抽击加以利用。发球球员无论堆叠站位如何，都必须从正确的底线发球区后方发球；搭档可以站在自己一侧的任何位置，包括发球员旁边或厨房区附近。
Start with half stacking on the return side only. Have your team decide your preferred sides, then stack together on the correct side before each return and switch after the return is hit. This one-sided version builds the habit without requiring synchronization on every serve.
Signal the switch direction before every serve rather than relying on memory. A quick verbal call or pre-agreed hand signal eliminates the hesitation that produces collisions during the switch. As the switch becomes automatic, start using it to set up specific shot patterns. This means stack wide to invite a crosscourt return your partner has pre-loaded to intercept.
Example
由于计分规定A球员从左侧发球，双方球员都堆叠在场地右侧；当A球员发球时，双方交叉——A移向左侧，搭档移向右侧——在回球到达之前，双方都到达了各自正手覆盖中路的位置。
Why it matters
堆叠站位让一支组合能够无视比分、自行决定场地站位，而不是接受轮换所产生的位置安排。一支拥有正手优势球员或明显反手短板的组合，可以在整场比赛中中和这些因素。
How it shows up on video
Watch where each player is standing just before the serve and then where they end up when the rally reaches the kitchen line. If the team is stacking effectively, the switch should be completed before the return arrives. This means review whether coverage gaps appear during the switch. This indicates timing or communication issues.
Common mistakes
- Switching too slowly after the serve, creating a temporary coverage gap that the return team exploits with a down-the-line drive.
- The server moving to the wrong side during the switch. This means both players must know in advance which direction to go. A collision at the center is common in teams new to stacking.
- Using full stacking before the switch is reliably clean. This means half stacking (on only one side of the rotation) is a safer starting point that builds the habit before applying it to every serve.
- Forgetting that the server must still serve from behind the correct baseline position regardless of where the partner is stacked.

SwingVantage tracks each player's court position at key moments. This means during the serve, during the switch, and at the kitchen line. This means helping identify whether the stack and switch sequence is being completed before the return arrives or whether coverage gaps are opening during the transition.
Frequently asked questions
堆叠站位合法吗？
合法——堆叠完全合法。规则规定了发球球员必须站在哪里（正确底线区域后方）以及球必须落在哪里，但对非发球搭档在发球前后应站在哪里没有任何规定。
完全堆叠和半堆叠有什么区别？
完全堆叠把堆叠加切换应用于每一次发球和接发球——全部四种轮换。半堆叠只在发球时或只在接发球时使用，减少组合需要执行的切换次数，同时依然能纠正最有问题的位置轮换。
对手能反制堆叠站位吗？
能——最直接的反制方式，是在切换过程中把球回球或抽击到发球方让出的一侧，瞄准那个临时的覆盖空档。堆叠的组合必须切换得又快又干净，才能关上这扇窗口。
