1. Accuracy is not important in the slightest. Use centipawn loss or some other metric to analyze your games more effectively.
2. Computers play as near to perfect as we can get right now. Your question rephrased is just, "Which is more common, attacking play or defensive play?" It is decently difficult to answer this question, as computers play attacks when they are decently sure it will succeed.
I will play a game and think my moves are good and receive a low ranking. I will play a game with my coach present and where I do not agree with the moves but it will score in the 90's. My question is twofold. 1. How important is accuracy? 2. Does the computer prefer a more attacking style or defensive style?
I am 47 and have only been playing for 6 months and am loving this site and this game.
