• 
  
  So first of all let me just explain what the strategies are,
  我先解释一下其中的策略吧
• 
  
  so I'm assuming the row player is Venus
  横行代表维纳斯
• 
  
  and the column player is Serena.
  竖行代表塞丽娜
• 
  
  I'm assuming that if Venus chooses L
  如果维纳斯选择了L
• 
  
  that means she attempts to pass Serena to Serena's left,
  这表示她向塞丽娜左侧发穿越球
• 
  
  we'll orient things from Serena's point of view,
  我们是以塞丽娜的视角为标准的
• 
  
  and if she hits right that means
  如果她选R则表示
• 
  
  she's attempting to pass Serena on Serena's right.
  向塞丽娜的右侧发穿越球
• 
  
  If Serena chooses L that means
  如果塞丽娜选l表示
• 
  
  she cheats slightly towards her left:
  作为回应 她稍向左倾
• 
  
  not cheats in the sense of breaking the rules,
  这里不是说她作弊的意思
• 
  
  but cheats in terms of where she's standing or leaning.
  它指的是向哪个方向稍微倾斜
