In chess, material refers to the pieces on the board, and a player's goal is to increase their material advantage over their opponent. This can be achieved by capturing the opponent's pieces or by forcing them to make exchanges that leave the player with a more advantageous position. In this video, we will explore the basics of gain of material, including how to recognize opportunities to capture pieces, how to make advantageous exchanges, and how to use these techniques to build a winning position. We will also look at some common pitfalls to avoid, such as giving up material in the wrong situations, and also discuss how material advantage can impact the outcome of a game.
