The Critical Moment: a4

The position after 1.d4 d5 2.c4 dxc4 3.e4 b5 4.a4 c6 is the tabiya of the Greco Variation. White immediately challenges your b5-pawn, threatening to undermine your entire queenside structure. Your pawns on b5 and c4 look solid, but they are vulnerable to the axb5 break. If White captures on b5, you recapture with ...cxb5, and then your pawn chain is gone — but you get open files and piece activity in return. This is the main battleground: White wants to shatter your pawn shield; you want to use it for counterplay.

The Main Line: axb5

White's best and most common move is axb5, played in over 273,000 games. After axb5 cxb5 Nc3 Bd7, you develop your light-squared bishop to d7, where it protects the b5-pawn and keeps an eye on the centre. White scores 53.3% from here — but that also means you hold your own in nearly half of all games. Your plan is straightforward: complete your development, maintain tension in the centre, and look to exploit the open a-file and your extra pawn on c4 if White mishandles it.

What to Watch Out For

Your opponents will sometimes deviate from axb5. The second most popular move is Nc3 (89,249 games), where White scores 54.4%. From Nc3, prepare ...Bd7 and keep an eye on e4-e5 ideas. The move d5 (19,769 games) is actually a mistake according to the engine — it loses roughly 1.1 pawns compared to axb5. e5 (7,253 games) is an inaccuracy, losing about 0.8 pawns. Both of these are gifts: if your opponent plays d5 or e5, you have a clear positional advantage. In each case, focus on centre control and piece activity to exploit White's suboptimal choice.

Your Repertoire as Black

Statistically, White wins 53.3% of games when they play axb5, 54.4% after Nc3, 53.1% after b3, 51.5% after d5, 53.1% after Nf3, and 55.9% after e5. Black wins 42.6% overall across all lines — far from hopeless. Know your main responses: after axb5 play ...cxb5 Nc3 Bd7 as in the main line; after Nc3 prepare ...Bd7 and keep the centre under watch; after b3 prepare to challenge with ...d5 ideas; after d5 or e5 from White you have a clear positional advantage. Stay solid, don't panic over the +0.59, and remember that the Greco Variation rewards players who understand pawn structures.
