  what I claim is the equilibrium strategy 1/3, 1/3, 1/3
  所谓的均衡策略1/3, 1/3, 1/3
• 
  
  against 1/3, 1/3, 1/3, I get 0
  来应对对方相同的策略我的收益是0
• 
  
  and if I played any other strategy I'd still get 0,
  如果我采用其他策略收益仍然是0
• 
  
  Is that right?
  是这样吧
• 
  
  So therefore playing 1/3, 1/3, 1/3 is indeed a best response,
  因此说1/3的混合策略是最佳对策
• 
  
  albeit weakly, it is indeed a best response
  尽管是弱最佳对策
• 
  
  and this is in fact a Nash Equilibrium.
  但是它的确个纳什均衡
• 
  
  So what we've shown here is in "Rock, paper, scissors"
  我们发现在石头剪子布中
• 
  
  playing 1/3,1/3,1/3 against
  用1/3的混合策略来应对
• 
  
  the other guy playing 1/3,1/3,1/3 is a best response,
  对手的1/3的混合策略是个最佳对策
• 
  
  anything would be a best response,
  最佳对策有很多种
• 
  
  but in particular it's a best response.
  但这个就是其中的一种
