About the Queen's Gambit Accepted
After 1.d4 d5 2.c4, Black takes with 2...dxc4. Black does not try to keep the pawn but uses the time to develop and hit the centre.
White usually wins the pawn back with e3 and Bxc4.
Black strikes back with ...c5 and ...e6, often getting an isolated d-pawn fight.
Holding the pawn with ...b5 is usually a mistake: a4 breaks the chain.
