I find it also amusing that chess indeed is the sport that involves mentally and psychological battle between you and your opponent. The slightest mistake could definitely cost the match that may have lasted for several hours depending on the game format (e.g. classical, rapid, blitz, or bullet). Though many have argued that chess is not considered as a "real sport", I do think that suffering a loss here can be brutally painful.
I am just thrilled that this sport has been widespread recognized and its popularity is steadily increasing. I just hope that more people would try it out as it is definitely enjoyable!
But in chess this is no possible, as nothing on the board is up to chance and the one to win is simply the one that plays the best.
