How to Play the Queen's Gambit Accepted: Slav Gambit
After 1.d4 d5 2.c4 dxc4 3.Nf3 b5, you have chosen a sharp way to hold the extra pawn. The position is tricky, and White already has strong pressure, so your main job is simple: survive the first wave, keep your structure as healthy as possible, and know the most forcing answer when White immediately challenges the queenside. The drill below puts you in the hot seat and lets you practise the exact position that matters most.

This opening is less about grabbing space and more about defending the c4 pawn without falling behind in development. White is trying to punish the pawn grab quickly, and the board is already tense after 3...b5. Your practical goal is to make the queenside support work long enough to reach a playable middlegame, not to pretend that you are comfortably better. The stats and engine both say White is the one pressing here, so treat every move as a test of accuracy.
The key reply White uses most
The engine's best move here is a4, and that is also the most common continuation by a wide margin. The idea is direct: White challenges your queenside structure immediately and tries to open lines before you can settle. In the main engine line, a4 c6 axb5 cxb5 follows, which shows how concrete this position is. If you are Black, this is the critical moment to know, because the whole opening often revolves around whether you can keep your queenside together after that pressure.
What the numbers say about this line
Stockfish rates this +0.75, a clear advantage for White. That means you are worse here and need to play accurately just to keep the game going. The database backs that up too: across 222,945 games at this exact position, White scores 57.8%, draws 4.0%, and Black scores 38.2%. In other words, this is not a line to choose if you want a safe equal game; it is a fighting opening where White gets the easier play.
The moves you need to respect most
Several White moves are common, but one stands out as the main practical test. The most-played continuations are a4 with 72,159 games, Nc3 with 43,603 games, e3 with 42,542 games, e4 with 25,463 games, g3 with 20,349 games, and Bf4 with 7,797 games. Among these, a4 is the most important because it is both the engine's choice and the most frequent try. The others still matter, but they are less forcing than the immediate queenside challenge.
Common mistakes to avoid as White
The database marks e4 as an inaccuracy, and it also marks g3 and Bf4 as inaccuracies. The note attached to each one is simple: a4 was better. For you as Black, that is useful because it tells you where White players often drift away from the most challenging continuation. But do not get careless just because a move is labelled inaccurate; White is still better in the position, and you still need to know how to respond cleanly when the queenside is attacked.

The most-played continuations are **a4**, **Nc3**, **e3**, **e4**, **g3**, and **Bf4**. Among them, **a4** is by far the main practical test. The others appear often enough that you should recognise them, but the position is built around the queenside challenge.
