If you have been playing chess for a while, you are probably familiar with the terms “evaluation” or “assessment” of the position. All variations in chess books and magazines end with an evaluation and you have surely heard players ending their lines with words like “white is slightly better” or “black is clearly better” or “this side has a decisive advantage”. Things may seem fairly simple when the evaluation is given to you by someone else, but it isn’t that easy in practice when you will have to do the same in your games, for example. Evaluating a position correctly is an important skill for a chess player, for a number of reasons.
