Dear Chess Friends! 

There are two types of advantage:

⠀

1) Static is an advantage that lasts throughout the game. It remains, when there are no abrupt changes in the position.

⠀

An example of a static advantage: extra material, better pawn structure, space advantage, bishop pair in an open position.

⠀

2) Dynamic is a short-term advantage that can disappear after a few turns.

⠀

This is, for example, an initiative or lead in development. You retain the initiative as long as you make moves that threaten your opponent. As soon as the quality of moves drops, the opponent will develop his moves and the initiative will disappear. The dynamic advantage also includes the ability to attack the king. If it appears in a position, then this is your clear advantage, otherwise the opponent can pull up pieces to protect the king.

⠀

What are these classifications for?

⠀

It is worth distinguishing between types of advantages, since you will be able to manage them during the game, namely, converting one type of advantage to another. For example, you have a static advantage of two bishops. In an open position, you can exchange one bishop for a knight, thereby worsening the opponent's pawn structure, so it will be possible to attack the opponent's pawns.

⠀

You can also sacrifice a pawn for attack or initiative, forcing your opponent to defend. Or vice versa, when you can't checkmate, you can win a pawn, move the game into an endgame and increase your chances of winning.

⠀

When planning a game, always keep the advantages in mind. Don't be afraid to sacrifice pieces and exchange them to power up your pieces.
