其中那个insideout900的评论我感觉完全切中要害
Frankly, all players face their own sets of challenges when it comes to their game and when you have a weakness it's not nearly that easy to fix.
With Alcaraz, he really enjoys just overpowering the opponent with no response back. And when his power is met back with interest or even more, when he is the one of defence, he doesn't know how to respond. That's because insinctive mechanisms kick in and he either panicks and makes a lot of UEs or just plays very defensive with 0 intent behind his shots.
It's a multi-layered issue and not just ingraved into things like match-up advantages.
When your ball bashing is inefficient, you need to throw in slower balls and wait for a better opportunity to strike, when your opponent dominates the baseline you need to hang on with the serve and accept the defeat, while waiting for a change in momentum, which is what he couldn't do properly against Dimitrov.
It's a game of hiding your technical weaknesses, hanging on mentally and problem solving on the run. A very difficult task when you don't have the most solid base out there.
======================
坦率地说，所有玩家在游戏中都会面临自己的一系列挑战，而当你有弱点时，修复起来就不那么容易了。
与阿尔卡拉兹一起，他真的很喜欢在没有任何回应的情况下压倒对手（用力量优势）。而当他的力量受到兴趣甚至更多的反击时，当他是防守者时，他不知道如何反应。这是因为本能机制启动了，他要么惊慌失措，造成很多误判，要么只是打得很保守，进攻意图为零。
这是一个多层次的问题，而不仅仅是刻在对决优势之类的事情上。
当你的击球效率低下时，你需要投入较慢的球，等待更好的击球机会，当对手占据底线时，你需要坚持发球并接受失败，同时等待势头的变化，这是他在对阵迪米特洛夫时无法做到的。
这是一个隐藏你的技术弱点、保持精神并在奔跑中解决问题的游戏。当你没有最坚实的基础时，这是一项非常困难的任务。

Alcaraz tends to play a hard hitting game, which gave the impression to most he is a great baseliner thrown in any scenario, but in reality he is vulnerable when he is not on top of his opponent.
Matches like the USO semi and the recent AO quarterfinal exposed just that. When Alcaraz has a lot of room to manuever he finds powerful shots, dropshots, nice angles. But when Medvedev returned his power back with interest and when robbed of time, all of these 'nice' shots vanished because he couldn't execute the essential one, which was matching the rally pace of his opponent.
Against Zverev or against Dimi yesterday, when faced with hard hitting and forced to counterpunch, he became a sitting duck, feeding weak responses and errors.
This stems from 2 things: his footwork being less than elite and his hitting technique from both wings being out of sync with his footwork.
On the FH he does the arm charging thing, except when he gets rushed he is out of balance and tends to fall backwards, resulting in a weaker, loopier shot and on the BH side he gets jammed due to the stiff arm technique, being unable to generate any angle and pose a threat as a counterpuncher.
Also noticed deep slices make him fall backward on his FH when he is hitting it.
The fact his footwork and hitting technique are suboptimal when rushed greatly hurt his counterpunching and ability to construct points, which are a core part of what makes every great baseliner in the modern era.
By contrast, someone like Sinner executes the counterpunching and point construction better due to a more stable footwork and tighter hitting technique, which should win him more matches on average, but lacks the A game power and creativity of Alcaraz.
===================
阿尔卡拉斯倾向于打一场强硬的比赛，这给大多数人留下了他在任何情况下都是一个伟大的底线进攻投手的印象，但实际上，当他不在对手之上时候，他非常的脆弱。
USO 半决赛和最近的 AO 四分之一决赛等比赛就暴露了这一点。当阿尔卡拉斯有很大的操作空间时，他会找到强有力的正手进攻、吊球和漂亮的角度。但当梅德韦杰夫满怀兴趣地恢复力量，并且时间被剥夺时，所有这些“漂亮”的进攻都消失了，因为他无法执行关键的一个部分，与对手的底线强相持相匹配。
对阵兹维列夫或昨天对阵迪米，当面对猛烈打击并被迫反击时，他变成了一只待宰的鸭子，反应无力，失误不断。
这源于两件事：他的步法不够出色，以及他的两翼击球技术与他的步法不同步。
在正手侧，他会用手臂冲锋，而他被调动时，他会失去平衡并倾向于向后摔倒，从而导致反击更弱、更容易失误；而在反手侧，他会由于僵硬的手臂技术而被卡住，无法进攻。产生任何角度并构成反击的威胁。
还注意到，当他击球时，深切球会让他的FH向后摔倒。
事实上，他的步法和击球技术在冲刺时并不是最理想的，这极大地损害了他的反击能力和构建得分的能力，而这是现代每一个伟大的底线手的核心部分。
相比之下，像辛纳这样的人由于更稳定的步法和更严格的击球技术而能够更好地执行反击和建点，这应该会让他平均赢得更多比赛，但缺乏阿尔卡拉斯的A级比赛力量和创造力。

希望阿卡可以好好看看

炮王迪米，

正手遇到快节奏容易被挤住， 只能带后仰往上提， 这点更纳达尔有相似的地方。 迪米这种节奏快， 最近状态也好

一场比赛而已， 遇到对手状态好克自己的打法， 对方节奏快， 没办法身体向前发力， 还是看好阿卡。 不过阿卡在这种强密度的比赛当中， 总感觉打法对身体体力有点消耗大。

美网的输球完美的体现了他目前这个打法存在的弱点
