【論文摘要】ANALYSIS OF THE TACTICS USED BY THE CHINESE MIXED DOUBLES PAIRING OF SUN YINGSHA AND WANG CHUQIN AGAINST TAIWANESE TABLE TENNIS STARS LIN YUN-JU AND CHENG I-CHING AT THE 2021 WORLD TABLE TENNIS CHAMPIONSHIPS
摘要
目的：孫穎莎與王楚欽的混雙組合目前世界排名第一，獲得多個WTT大賽冠軍。希望透過解析技戰術組合之勝率，分析該混雙組合的優劣之處。方法：透過PYTHON標註工具與分析工具，獲取中國組合孫穎莎、王楚欽與台灣組合林昀儒與鄭怡靜在2021世界桌球錦標賽四強賽的技戰術分析，歸納孫穎莎、王楚欽為發球方以及接發球方時各技戰術組合的勝率以及使用次數，以解析該組合的優劣勢環節。結果與結論：孫穎莎、王楚欽在2021世錦賽四強賽中對陣林昀儒與鄭怡靜以3:1擊敗台灣組合，但內容相當接近，雙方實力相當。值得一提的是，孫穎莎與王楚欽組合在這場比賽中相持球部分（板數六板以上）的表現只有贏10球輸15球，略占下風，代表對於台灣組合而言，進入相持球有機會形成比賽的突破口。相對來說，孫穎莎與王楚欽組合在板數小於五板的時候直接贏球的比例相當高，才能拿下比賽的勝利。本文著重於針對板數小於五板的情況進行解析：當孫穎莎、王楚欽組合為發球方時，利用發球搶拉拿下了四球，勝率為100%。若是第三板使用擺短、反拉等較為被動的技術回球，勝率僅有20%。而作為接發球方時，孫穎莎與王楚欽組合戰術積極，有19球在接發球回擊後直接結束，並且有著63%的勝率，在接發球方面正有明顯的優勢。其中，孫穎莎最常使用的接發球技術為擺短，使用了7次，並且勝率高達86%。而王楚欽則以擰球技術為擅長，使用7次擰球作為接發球技術，同樣勝率為86%。孫穎莎與王楚欽組合戰術積極，並且主動攻擊情況下的勝率相當高。因此，林鄭組合若想要突破，需著重接發球回擊質量，主動進行攻擊。當林鄭組合作為發球方時，則需提防孫穎莎的擺短控制以及王楚欽的擰球回擊，才有取勝的機會。

Introduction: The mixed doubles pairing of Sun Yingsha and Wang Chuqin, currently ranked number one in the world, has won multiple WTT major titles. This analysis aims to examine the strengths and weaknesses of this pairing by analyzing their winning rates against the tactics used by Taiwanese pairing Lin Yun-ju and Cheng I-ching at the 2021 World Table Tennis Championships. Method: The analysis was conducted using Python annotation and analysis tools to gather data on the tactics employed by both pairings in the semi-finals match, including the serving and receiving strategies used by Sun Yingsha and Wang Chuqin and their opponents. This data was used to compare the winning rates and frequency of tactics used by both pairs, allowing us to identify the strengths and weaknesses of the Chinese mixed doubles pairing. Results and Conclusion: In the semi-finals of the 2021 World Table Tennis Championships, Sun and Wang defeated the Taiwanese pairing of Lin Yun-ju and Cheng I-ching 3-1 in a closely contested match. It is worth noting that Sun and Wang were slightly at a disadvantage in the part of the game where both sides were using more than six shots per rally, winning only 10 points while losing 15 points., the Taiwanese pairing had opportunities to break through during those moments. On the other hand, Sun and Wangs win -loss record in exchanges of less than five is relatively high, and this is key to their victories. This article focuses on analyzing the situation where there are less than five exchanges. When Sun and Wang are serving, they have a 100% win rate when they use serve-and-attack tactics to win four points. If they use passive techniques like drop shots and blocks for the third ball, their win rate drops to only 20%. As receivers, Sun and Wang adopt aggressive tactics and have a clear advantage in receiving, with 19 points directly won after receiving, and a 63% win rate. Sun often uses the drop shot technique and has a high win rate of 86% in seven attempts, while Wang excels at using the twist return, with a win rate of 86% in seven attempts as well. Based on the above analysis, the combination of Sun Yingsha and Wang Chuqin is aggressive in tactics and has a high winning rate when taking the initiative to attack. Therefore, if Lin and Cheng want to break through, they need to focus on the quality of their return when receiving serves and take the initiative to attack. When Lin and Cheng are the serving side, they need to be wary of Suns short control a nd Wangs twist return to have a chance of winning.
