Plain-English Definition
A positional sacrifice may create active pieces, weak squares, open files, safer king, or a blockade. The material may never come back directly.
Why It Matters
It separates tactical calculation from strategic investment.
Common Signs in Games
- The sacrifice creates permanent activity or weak squares.
- The opponent material cannot easily coordinate.
- The compensation survives after checks end.
Common Mistakes
- Sacrificing for vague vibes.
- Ignoring whether compensation is durable.
- Failing to keep pieces active after the sacrifice.
