4. cxd5
White captures the d5 pawn in an attempt to give Black an isolated queen's pawn. Black has two viable responses:
/4...exd5/ is the main line, replacing the captured pawn to control the center.
/4...cxd4/ is the Schara gambit, luring White's queen into the center in order to develop quickly with tempo on the queen.
