Sacrifice
Giving up material on purpose for a larger gain — mate, more material, or a winning attack.
A sound sacrifice trades material for something concrete: a forced mate, the recovery of more material a few moves later, or a decisive attack the opponent cannot survive.
A speculative sacrifice trades material for pressure that is hard to calculate to the end — the domain of attacking players and, sometimes, of hope.
The most beautiful and instructive games hinge on sacrifices. Learning which ones are sound teaches you what activity and king safety are really worth.
Sacrificing on feeling without calculating the follow-up, then finding the attack simply runs out.
