In a gold medal match at World Championships 2019 (World Taekwondo), there was a VERY controversial match. Bianca Walkden of Great Britain was up against Zheng Shiyun of China. Down 10-20, but realizing that her opponent had already generated several fouls, Walkden proceeded to focus on pushing her opponent instead of striking, forcing a few more exiting-the-ring fouls that led to Shiyun being disqualified and Walkden being awarded the gold by default. The response from Shiyun's camp was fierce. Many have called for the referee to be barred from refereeing World Taekwondo matches and for Walkden's championship to be taken away. Walkden's response boils down to "a win is a win." This video shows Walkden's switch in tactics that led to Zheng Shiyun being disqualified. I'm torn. On one hand, there's plenty of combat sports where forcing your opponent out of the ring is a valid tactic (sumo, sanda, fencing). But on the other hand, in these competitions, I think it always generates points for the person pushing, not fouls for the person being pushed, clearly showing that it's intended to be a legitimate offensive technique. The fact that pushes don't generate points in taekwondo, and that a few points couldn't have overcome the ten point lead that Shiyun had generated, suggests to me that pushing was never meant to be used this way in taekwondo. I have trouble saying that Walkden's victory should be taken away, but I do think the rules should be clarified to prevent this tactic from being used again. Thoughts?
