Wouldn’t say it is impossible but it requires a lot of training with bots and reviewing which moves can be made better after a match. I take chess as a problem solving puzzle whereby the goal is to trap the opponent king first before mine. There may be some strategy involved like how to get the king exposed by forcing it out or forcing it in. In the meantime, the defense also need to be there to prevent our own king at risk. After a few matches, I’m sure you will have a tired mind and for my case I can easily sleep off after 5 to 7 matches.
