In order to learn from those mistakes, can someone better explain the definition of an inaccuracy for me? I think it has something to do with how many attackers and defenders are on a certain square, but I'm not certain that I am correct.
Its when you make a mistake greater than 50 centipawn loss but lesser than 100 centipawn loss(correct me if im wrong).
Inaccuracy:
1. The quality or condition of being inaccurate.
2. An instance of being inaccurate; an error.
It's the smallest form of a mistake.
It wasn't the best move, but it wasn't the worst move (blunder). It is a move that will not hinder your game progress.
Inaccuracies are often related with positional mistakes. You will feel the consequences of a mistake in the long term. Most of the times inaccuracies are not obvious, even for very skilled players. Inaccuracies are normal, and you should not worry too much about them. Unless you have a deep theoretical knowledge or you can see many moves ahead in your mind, it will be hard for you to understand most of your inaccuracies.
Mistakes on the other hand are more obvious. Maybe you just lost a pawn, or a rook for a bishop. You might recover from a mistake if you are playing against a human, but it's really hard.
Blunders are often huge mistakes. It's not hard to recognize a blunder. A blunder might be hanging a Queen or a Rook, falling for mate, or missed checkmate yourself. You cannot recover from a blunder, unless you already had a big advantage before blundering.
My previous answer was just to troll.
Cheers.
