Chen Long is wont to make his opponents, except Lee CW of course, feel comfortable playing him, at least most of the time; such a nice guy.
I think Chen Long learns too much from Xia XZ, the runner, and too little from, say GM Tang Xianhu (not sure how much time CL had under his coaching), to be more like Lin Dan. Chen Long ought to know that his opponents are fully aware of his killer smash, so none of them will want to lift the shuttle if they can help it; expect most of his net shots to be returned with net shots 90% of the time.
May be Chen Long's play style is so tailored to deal with LCW that he is unable to play well with others.
