Hello everybody this is Profesor Jake and welcome back to a new activity.
After placing and understanding our chessboard we are going to see another important fact before starting to play Chess.
How much does our pieces cost?
The value of chess pieces indicates the value of the different pieces and their relationship among them.
Each piece has its strengths and weaknesses, and therefore the value of each piece varies. Let's see what the value of each piece is below!
Piece exchanges are complex! Exchanges of pieces of equal value, such as a pawn for a pawn or a queen for a queen, are fine in terms of value, but WATCH OUT because it's never so easy.
A typical exchange would be two minor pieces (knights or bishops) for a rook and a pawn. Just because the exchange is six points for six points does not necessarily mean that it is an even exchange. There are other factors of the position that must also be taken into consideration.
Now you know what chess piece values are, what their relative values are, how engine evaluations are connected to piece values, and how to evaluate various piece exchanges.
Here's what you need to know about the value of the pieces:
At the end you will find some questions.

Piece exchanges are complex! Exchanges of pieces of equal value, such as a pawn for a pawn or a queen for a queen, are fine in terms of value, but WATCH OUT because it's never so easy.
Let's look at this position. Black has moved the knight from f6 to g8, offering an exchange of bishops. White, after much thought, withdrew his bishop to f2. Was it wise to avoid the exchange? His reasoning must have been like this:
■ If the opponent offers the exchange, then he is willing to get rid of the bishops and therefore, why should I let him?
■ Anyway, my bishop will be useful to attack his weak dark squares.
■ If I take on e7, his knight will be activated by moving out of his passive square on g8.
All considerations are wrong!
The first point falls into the trap of assuming your opponent knows what he is doing - and he doesn't have to, the second point of forgetting the fact that Black's bishop is far more essential for defending the dark squares than White's bishop is for attacking them, the third point confuses short-term considerations with long-term goals.
With his pawns on c6, d5, f5 and g6, Black has neglected the black squares. White has control of a splendid central square on e5, and Black has no comparable square. The black bishop on e7 is the firewall of the dark squares. When it is exchanged, the battle for the dark squares is over. In fact, after 1.Bxe7 Nxe7 2.h4! the threat of an h5 break is always looming over Black's position and White has a huge advantage.
If you think "His bishop is more useful to him than mine is to you", switch them.
At the end you will find some questions.

¿Cuánto cuestan nuestras piezas?
De hecho no es cierto, la idea es saber su valor en caso que estemos capturando las piezas de nuestro oponente o que tu oponente esté capturando las tuyas.
Los intercambios de piezas son complejos. Los intercambios de piezas de igual valor, como un peón por un peón o una reina por una reina, están bien en términos de valor, pero ¡ATENCIÓN! porque nunca es tan fácil.
Veamos esta posición. El negro ha movido el caballo de f6 a g8, ofreciendo un cambio de alfiles. El blanco, tras pensárselo mucho, retiró su alfil a f2. ¿Fue acertado evitar el cambio? Su razonamiento debe haber sido así:
■ Si el rival ofrece el cambio, entonces es que está dispuesto a deshacerse de los alfiles y por tanto, ¿por qué debería dejarle?.
■ De todos modos, mi alfil va a ser útil para atacar sobre sus débiles casillas negras.
■ Si tomo en e7, su caballo se activará saliendo de su casilla pasiva en g8.
¡Todas las consideraciones son erróneas!
El primer punto cae en la trampa de asumir que tu oponente sabe lo que está haciendo - y no tiene por que ser así, el segundo punto de olvidar el hecho de que el alfil de las negras es mucho más esencial para la defensa de las casillas negras que el alfil de las blancas para atacarlas, el tercer punto confunde las consideraciones a corto plazo con los objetivos a largo plazo.
Con sus peones en c6, d5, f5 y g6, el negro ha descuidado las casillas de color negro. Las blancas tienen el control de una espléndida casilla central en e5, y las negras no tienen ninguna casilla comparable. El alfil negro en e7 es el cortafuegos de las casillas negras. Cuando se intercambia, la batalla por las casillas negras ha terminado. De hecho, después de 1.Axe7 Cxe7 2.h4! la amenaza de una ruptura h5 está siempre acechando a la posición de las negras y las blancas tienen una gran ventaja.
Si crees que "Su alfil es más útil para él que el mío para ti", cámbialos.
