I saw a bit more of the clip. I could see how the blue guy lost which is unfortunate for him. He looks younger and fitter but he seemed to get himself into a quandary and couldn't find a way out.Haha watch the game, interesting how it changes. The blue guy is playing himself going for too much and getting frustrated, the orange guy is playing the opponent.
Broadly speaking, he didn't realize his assets of being younger and fitter. He didn't need to continuously play the same exhausting, loopy shots. Just careful, flatter slower but sharper angle shots would have done the orange guy in. Hehehe
