Gambit
A gambit is an opening in which a player deliberately sacrifices material, usually a pawn, in exchange for compensation such as faster development, greater central control, open lines for pieces, or an attack on the opponent's king. The side accepting the gambit must decide whether to hold onto the extra material and defend accurately, or return it to simplify and neutralize the attacker's initiative, which is often the safer practical choice. Gambits matter strategically because they trade a long-term asset (material) for a short-term one (time and activity), making them especially potent in faster time controls or against opponents unfamiliar with the resulting sharp positions. A classic example is the King's Gambit (1.e4 e5 2.f4), where White offers a pawn to open the f-file and accelerate development, aiming to build a strong attack before Black can consolidate the extra material.
