Sacrifices in chess: giving up material to win
Losing a piece isn't always a mistake. Here's how to recognize and evaluate a real sacrifice, rather than a plain blunder.
Key takeaway
A sacrifice isn't a free gift: it's a calculation, with concrete compensation expected in return for the material given up.
Willingly giving up a piece can seem to defy all logic, and yet, it's sometimes the best move on the board. The difference between a sacrifice and a blunder comes down to one word: calculation.
Sacrifice or blunder: the difference
A blunder is losing material without seeing it coming. A sacrifice is giving up material on purpose, having calculated (or strongly anticipated) concrete compensation in return. The question to ask before sacrificing: "what exactly do I get in exchange?"
Types of compensation
- ✓A forced mate, calculated all the way through
- ✓A lasting attack against the enemy king, even without an immediately visible mate
- ✓Piece activity far superior to the opponent's
- ✓The opponent's pawn structure permanently wrecked
- ✓A tempo gained in development over the opponent
A concrete example
In the diagram above, White just played Qxh7+, sacrificing the queen. Black's king has no option other than to capture on h7: its previously intact castled position is suddenly wide open for the rest of White's attack.
How to evaluate a sacrifice before playing it
"I have a good feeling about it" is never enough. Before sacrificing, calculate at least the opponent's first forced replies, and identify concretely what you're gaining: a visible mate, or at minimum practical chances clearly worth more than the piece you're giving up.
Key takeaways
- ✓A sacrifice is distinguished from a blunder by the calculation and intent behind the move
- ✓Compensation can be a forced mate, a lasting attack, activity, or tempo
- ✓Before sacrificing, identify precisely what you get in exchange
- ✓A successful sacrifice often rips open the enemy king's position for the rest of the attack
