In chess, an "advantage" refers to a situation in which one player is in a stronger position compared to the other player. A player with a slight advantage is said to be "better." A player with an large advantage, or multiple types of slight advantage, is said to be "winning." A player with a massive advantage or series of advantages is said to be "crushing." Advantages in chess can and often are measured in approximate pawn equivalents.

There are three main types of advantages:

1. Material advantage - this refers to one player having more and/or better pieces than the other player.

2. Positional advantage - this refers to one player having their pieces placed in a better position or formation compared to the other player.

3. Time advantage - this refers to one player having the initiative and thus being able to dictate the pace and nature of play. See tempo.
