Inaccuracy means you played a move that cost you a small amount of points.
You need to look at what the analysis recommends so you'll know why your move was inaccurate.
But at your rating group, inaccuracies aren't so bad. We're not computers, and we're not masters... yet. When we push ourselves to play outside the box, to play something unique and spectacular, we make mistakes along the way.
When I analysis my game I find a lot of inaccuracies and I don't know why they are inaccuracies What to do ???
