Catalan Opening Sacrifice in Chess

A catalan opening sacrifice is a tactical decision in the Catalan Opening where White intentionally gives up material—often a pawn—to gain initiative, open lines, or force a favorable central break. A defining feature is the Catalan setup with c4 and g3 (typically aiming for d4 and pressure on the center), followed by a sacrifice that changes the pawn structure or opens the c- and d-files.
