One reason I love chess is that all is fair in chess. Think about that for a moment. How often is everything fair? In chess, both sides are about as evenly balanced as can be achieved in a turn-based game. By saying chess is fair, I mean that any opening, strategy, or tactic, if over the board, is fair. Off the board, there are disagreeable things a player can do to make the environment more obnoxious for his opponent--these things I disapprove of. But anything played on the board is fair. Thus, I do not sympathize with sore losers who find fault in their opponent for winning based upon so-called "luck." I will tell you what "luck" means in chess. If your opponent wins on luck, it is because you missed something. You were at fault, period, and you deserve to lose every single time that you lose, and you deserve to win every time that you win. Therefore it is contemptible to be a sore loser in such a game, certainly online where each player has maximum control over their environment, and the other player's influence on one's environment is negligible or nonexistent.
The other thing I love about chess is that it is universal and timeless. Many people around the world play chess, and it is possible to find a game anywhere that you go. Chess has been around for centuries and found its way into history. As for the future, computers be damned, chess will never die. Unless our intellects evolve to match that of computers, chess will always be complicated enough to challenge some of the finest minds in the world, because even they make mistakes.
