By the way,  I am college student who really love chess. I consumed 3-8 hours in a day just to play chess in two chess sites , chess.com is the one. I cannot sleep if I not play in just one night. My addiction in chess is usual to other players but in my case, it was totally bad because I spend a lot of money in renting in computer shop, instead of buying foods and school supplies in my study. But, chess addiction is normal for a teenager who wants to be stronger than before. I can say that it is worth it and no regrets and doubt to be a chess-maniac player. I don't have any kinds of rating. I just join the tournament if I invited and enjoy it up to the last minute of the last round of my game. Comment here if I am right or not. Thank you if you read this simple blog and have fun in playing chess here in chess.com.
