A sacrifice is deliberately giving up material — a pawn, a piece, or more — in return for something worth even more, such as a mating attack, a winning position, or material won back later.
Unlike a blunder, a sacrifice is intentional and calculated. You hand over material because you’ve judged the compensation is worth it: a direct attack on the king, a decisive lead in development, a crushing pawn structure, or a forced sequence that wins more than you gave.
Sacrifices split into two kinds. A sound sacrifice can be calculated to a clear gain, like the classic Greek-gift bishop sacrifice on h7 that rips open the castled king. A speculative (or ‘sham’) sacrifice gambles on long-term pressure that you can’t calculate to the end.
Before sacrificing, ask what concrete return you’re getting. If you can’t name the compensation — checkmate, a fork that wins the material back, an unstoppable attack — it’s probably not a sacrifice but a mistake.
A sacrifice is deliberate, played for calculated compensation like an attack or material won back. A blunder is an oversight that simply loses material for nothing. Intent and compensation are what separate them.
A sound sacrifice has concrete compensation you can point to — a forced mate, a fork that regains the material, or an attack the opponent can’t defend. If you can’t name the return, treat it as risky.
