是不是只有对方没有碰到的球才算winner,
只要对方碰到了,不管有没有足够的时间和合适的位置,
只要碰到球,但是失误了,就算对方的unforce error? |

发帖数: 7271 | 3 上周日正好看见曾搭讪过我的牛人的比赛，偷录了一个set。
好像是白衣6：0蓝衣。
蓝衣人我没有任何信息，看起来2，30岁的样子。最近见到好几次他跟
白衣练球和打比赛。练球时看起来底线不错，不过好像发球较弱，比赛
总是输得甚惨，基本hold不住，也break不了白衣。
白衣人，据说10岁开始练球，东方式正手，球很平，技术很全面，发球
很不错。岁数看着不小，但是具体不详，也可能只是显老。有三个男孩，
最大的小孩8，9岁。打上3个set好像没见体力问题。
贴一个他们的比赛录像，偷拍的角度不好，大家将就。我在边上练发球，
所以噪声比较多。（另：上载400M好慢啊，大家给点包子慰劳慰劳吧？）

请各位鉴定鉴定两人的NTRP吧。以后有空再谈一谈白衣人跟我搭讪打球

同有些人打球，球的高度，PACE正好在comfortable zone,就容易很多。
其实，现在的unforced error 这个说法是不科学的。绝大多数unforced error是
forced的。如果球都往中间打，那还有什麽unforced error. |

Your three level theory is very interesting and I think there is a lot of
truth in it.
The way I interpret it:
Level 1: waiting for your opponent's unforced error
Level 2: creating opportunities for your opponent's unforced error(yes still
unforced)
Level 3: force your opponent into errors
Right now I am trying to get to level 2 when playing with similar level
players.
Your suggestion about the 'charging' makes sense too, as was jjch's comments

But I guess I don't really see anything wrong with your strategy here.
Yes, you made three consecutive unforced errors at your match points which
probably cost you the match. But, that doesn't mean what you did was wrong.
What went wrong was the fact that you were bothered by your errors. And if I
take a guess I would say your second and third unforced error were probably
a chain reaction from the first one. And the reason you failed for the
first one is that y |

发帖数: 6757 | 20 是这样。 那么为什么会出现这些 unforced error 呢？ 在我们这个水平阶段， 练习
时一般对拉对抽是不会经常发生这种 unforced error的。 那么为什么比赛时会经常发

力是指没能没能把专注力控制在球和自己。 比赛时常常受其他因素影响， 比如得要赢

的对待每一个球， 完全忽略他们，自然也会赢了（supposed that your techniques
are better than theirs, in most case they are)。

这次Federer应该没有料想到和Safin的比赛那么tough，Safin5盘从头到尾都没有一点
心里波动，unforced error比Federer少那么多，简直神了。可能是因为Federer领先
其他人太多，所以Safin比较容易focus on the match。
结果不错，Federer有了更好的动力提高自己的体力和发球，希望看到他和Safin的rivalr

下次两个碰到还是Federer的胜算大一点。

好担心啊，觉得这个老怪Agassi不会撞对了风水（现场观众好夸张，我怕影响GG睡觉调的
声音特别小都可以感觉出来“压力”），真的要在今天创造历史了吧；而且Federer最拿
