Is chess a sport?

Most def. Yes!

Nope, Chess is a puzzle memory games. CPU memory and algorithm has proved it

Chess is a sport of the mind. Chess players can burn 6,000 - 7,000 calories per day while i know people that only burn 2,000 (theyre not very athletic). Chess is a sport and you use a lot of energy doing it. 

elite male soccer players from the eridevise only burn 3,500 calories on average so chess is just as demanding as soccer

I believe chess is a sport for the fact that during a game your blood pressure and heart rate SKY ROCKET. Joe Caplablanca died from a burst blood vessel from pressure and top GM's need personal fitness trainers. Imagine of having a heart rate of about 130bpm for sometimes 6hrs AT A TIME while playing chess.
