Play the Queen's Gambit Declined: Chigorin Defense with 3.Nc3

The Chigorin is an opening where you fight for the centre with pieces rather than pawns. Your knight on c6 already puts pressure on White's centre — it eyes the d4 pawn and supports active piece play throughout the game. With 3...e6 you've opened a diagonal for your light-squared bishop, but you've also blocked in your queen's bishop, which will need solving. White's main plan is to finish development with Nf3, then choose between e3 or Bf4, aiming for a solid but slightly comfortable position. Your job is to complete your development, castle kingside, and eventually activate that c8 bishop — the engine recommends starting with ...a6 to prepare queenside counterplay.

Stockfish's top move for White is 4.Nf3, played in over 327,000 games — roughly half of all games at this position. White scores 58.3% with it, reflecting that small +0.61 edge. The engine suggests the sequence: 4...a6 5.e3 Nf6. Your ...a6 claims queenside space and prepares further counterplay. Then ...Nf6 develops naturally and fights for central squares. This is a solid, modern approach: you keep the position semi-closed, get your pieces out, and wait for White to show their hand. You have time to manoeuvre — do not rush, develop harmoniously, and react to what White does.

Not every opponent knows the theory. Two moves in particular are worth knowing because they give you a clear advantage if White plays them. 4.a3 is an inaccuracy, costing White about 0.6 pawns — the engine says Nf3 was better. White wastes a tempo on a move that doesn't fight for the centre or develop a piece. Simply keep developing solidly, happy to have an extra tempo and a fully equal game. 4.e4 is much worse: a full mistake that loses around 1.6 pawns for White. White overextends in the centre before development is complete. You can strike back energetically and exploit the overextension — after 4.e4, you're not just equal, you're firmly better according to the engine.

From 678,620 games at this position, the numbers paint a clear picture. White wins 56.8%, draws 3.8%, and Black wins 39.4%. Your chances are best when White plays inaccurate or weaker moves. White scores 54.6% after 4.a3 (that inaccuracy) and just 49.9% after 4.e4 — that's a below-average result for White, meaning you win more than you lose in that line! The most dangerous move for White is 4.Nf3, where they score 58.3%, so be ready to hold your own in that line. Meanwhile, 4.Bf4 (56.5% for White) and 4.cxd5 (55.9% for White) are also respectable for White but still below their overall average of 56.8%. Trust your position, develop, and look for the moment to strike.

Here is a quick summary of how to handle White's most-played continuations after 3.Nc3: 4.Nf3 (most common, best for White) — follow the engine's line: 4...a6 5.e3 Nf6, keeping the position solid and grounded. 4.e3 — a quiet line; develop sensibly with ...Nf6 and your remaining pieces, reaching a comfortable setup. 4.cxd5 — recapture and develop naturally with Nf6, reaching a straightforward position. 4.Bf4 — develop calmly with Nf6 and prepare to challenge White's piece placement. 4.a3 (inaccuracy) — just keep developing solidly, White has wasted a tempo and you have no worries. 4.e4 (mistake) — White loses 1.6 pawns according to the engine; react actively in the centre to punish the overextension. Learn these basic responses, and you will outscore the average Black player.
