Queen's Gambit Accepted, Classical Defense

In the Classical Defense, White does not build an enormous center immediately. White first develops the king's knight to f3, advances the e-pawn to e3 to open the bishop's diagonal, and recovers the pawn on c4 with that bishop. Black develops the king's knight and does not try to cling to the captured pawn.

Black's c-pawn advance to c5 is the central strategic point. It attacks White's pawn on d4 and forces a decision about supporting or transforming the center. In some continuations, White is left with an isolated pawn on d4, a pawn with no friendly pawns on adjacent files. It provides space and activity but can also be attacked.

The line develops pieces and challenges the center through direct ideas, but it is not passive. Both sides seek activity, and the timing of exchanges matters. Compared with the Central Variation, White prioritizes development and recovery on c4 before advancing the e-pawn to e4.
