Acquiring a good understanding of the positional elements is one of the keys that help you increase your strength as a player. These are concepts that one should always take into account, whatever the phase of the game. They help you decide how to place your pieces, which ones to keep and which to exchange, how to place your pawns and so on. Endgames are no different. In more complex ones, the same principles apply. It is important to know which ones favor you and how to put a better opposition in the ones you have to defend.
