The Slav Defense arises after 1.d4 d5 2.c4 c6 and falls under ECO code D10. Once regarded as an unorthodox way to handle the Queen's Gambit, the Slav has long since established itself as a major opening system in its own right. The logic is straightforward: rather than blocking the light-squared bishop behind an e6 pawn as in the QGD, Black supports d5 with the c-pawn, keeping the c8-h3 diagonal open for future bishop development. This typically allows Black to achieve a more active piece placement compared to the Queen's Gambit Declined.
