Chess is not one of those mindless games that you can play with your eyes closed. Chess requires strategy. You have to think 2 moves ahead. You have to anticipate your opponent's next move.
I'm in the middle of a chess game. I have my next few moves planned out. My opponent has underestimated me. He didn't know that this is a timed game. He also didn't know that I learned to play chess as a child. He thinks he's a Knight, he's really a Pawn. But in the end, it's all about the Queen!
