If you say that Magnus is your Lord then you are sinning! Come on that is an insult!
This is how chess can become a sin.

As for Tuffy, what you’re saying is that you feel because some people spend a lot of time on Chess, that means they worship chess. By that logic, every Olympic athlete worships the sport they are playing. There’s a difference between worshiping something and being extremely focused on/committed to something. Someone who becomes a surgeon is not necessarily worshiping the medical profession, just because they spend their lives studying to become and then practicing as a surgeon. Spending time playing chess is much better than say drinking, smoking, gambling, or doing other things that are truly not good for you. Your logic is flawed in another way: people don’t hold chess up as some kind of God. I play chess because it’s fun, but it also is a good mental/brain exercise. It’s important to keep “exercising your brain” and playing chess is a great way to do that. Stop trying to find problems where they don’t exist. There are plenty of problems in the world to worry about; don’t invent one with chess for crying out loud.
It's ok to have chess as a hobby but if you start loving chess more than you love God then it becomes a sin. Because of the commandment, "Thou shalt not make unto thee any graven image." Chess can become a god to people just like how a statue can become a god to people there is no difference what you worship if it's not God. A sin is a sin.

Do you have a sibling or friend or someone who’s better than you and it’s really frustrating you? No one agrees with you that chess is a religion or a graven image for anyone. People have clearly already stopped taking you seriously. If you think that playing chess a lot is a sin, then you repeating this garbage over and over is a bigger sin, so stop sinning and save everyone’s time.
Hey there! I want to tell you how chess can become a sin. Two of the ten commandments are, "Thou shalt have no gods before me." That god could be chess. The next one of the ten commandments is, "Thou shalt not make unto thee any graven image." That graven image could be chess. That means that you love chess more than you love God. These two ways chess can become a sin.
