Exchange sacrifice

Giving up a rook for a minor piece (the 'exchange') for positional compensation.

Sacrificing the exchange — rook for bishop or knight — trades material for something less tangible: a monster knight on an outpost, a shattered enemy structure, control of a colour, or a raging attack. Petrosian made it an art form.

It's usually a positional decision, not a forced win: you judge that the active minor piece and the concessions you win are worth more than the nominal material.

Why it matters

Knowing when the exchange is worth giving up frees you from counting material and lets you play for real, lasting advantages.

The mistake everyone makes

Clinging to a 'winning' exchange when your rook is passive and the opponent's knight dominates — the material count lies.
