Sacrifice
A sacrifice is a deliberate decision to give up material, such as a pawn, an exchange or a piece, in return for something else, like mate, a stronger attack, a better structure or a larger gain later.
A sacrifice means choosing to be worse off in material on purpose. The reward can be concrete, such as forced mate or recovering more than you gave, or positional, such as an open king, lasting activity or a crippled pawn structure for the opponent.
The difference between a sacrifice and a blunder is calculation. A real sacrifice has a purpose you can name and, for the tactical kind, a line you have seen through to the end. If you cannot name what the material buys, the move is a gamble. Concrete lines justify concrete sacrifices, while positional ones rest on judgment about long-term compensation.
Sacrifices often clear a square or a line, lure a defender away, or pull the enemy king into the open. Typical triggers are a king with few escape squares, a defender that guards two things, or a file that can be opened with tempo.
When the opponent offers one, do not accept automatically. Ask what the offered material is meant to achieve, and check whether declining or returning the material is better.
Sacrificing because a move looks attractive, rather than because the follow-up works, is the habit to break. Always count the forcing replies before giving up anything.
Compare it with Poisoned pawn. A poisoned pawn is a pawn that can be captured, but whose capture lets the opponent punish the greedy player with a tactic that costs more than the pawn is worth.
Compare it with Positional sacrifice. A positional sacrifice gives up material, usually a pawn or the exchange, not for a forced tactical gain but for lasting benefits such as space, a safer king, better piece placement or a damaged enemy structure.
Compare it with Queen sacrifice. A queen sacrifice gives up the strongest piece on the board, usually with a check or a capture, to win through a forced checkmate or to gain enough other material to be clearly ahead.
Knowing "Sacrifice" helps most once you can spot it in a real game. A first lesson with George Li starts from your own games and finds the tactics you keep missing.

A combination is a forcing sequence of moves, usually built from sacrifices and checks, in which every move leaves the opponent few or no choices and the sequence ends in a concrete gain such as mate or material.
An exchange sacrifice gives up a rook, worth five points, to capture a bishop or knight, worth three, in return for a positional or tactical gain that is worth more than the material lost.
A queen sacrifice gives up the strongest piece on the board, usually with a check or a capture, to win through a forced checkmate or to gain enough other material to be clearly ahead.
A positional sacrifice gives up material, usually a pawn or the exchange, not for a forced tactical gain but for lasting benefits such as space, a safer king, better piece placement or a damaged enemy structure.
Compensation is whatever a side holds in place of missing material: faster development, an exposed enemy king, strong squares, a ruined pawn structure or other trumps that balance an extra pawn or piece on the other side.
A material imbalance arises when the two sides own different kinds of material, such as a rook against two minor pieces or a queen against rook and bishop, so that simple point totals miss the real strengths of each army.
