How to play the Zukertort Opening: St. George Defense as Black
After 1.Nf3 a6, White has the move and the game is still very flexible. That flexibility cuts both ways: you have chosen a rare setup, but you also need to know what White is likely to do next and how to meet it. The drill below lets you practise the position from Black’s seat, so you can get used to the first important decisions instead of guessing over the board. The aim is simple: stay solid, answer White’s central ideas well, and avoid drifting into an early disadvantage.

This opening is not about an immediate tactical fight. It is about handling White’s most natural ways to take space and develop. In practice, White can aim for the centre with d4 or e4, build with g3, or choose quieter development with Nc3 or e3. Your job as Black is to meet those setups without falling behind in development or allowing White an easy grip on the board.
The engine’s best reply
Stockfish rates this +0.56, a small edge for White. That means you are slightly worse here.
The engine’s top continuation is c4, and the line given continues c4 c5 g3 Nc6. That tells you the practical direction: White is looking to claim space and steer the game into a more active middlegame, so you need to respond with accurate, principled play rather than passive waiting.
What the numbers say
Across 166,319 games at this exact position, White scores 52.3%, draws 4.4%, and Black wins 43.3%. That is a useful reminder that this is not an equal, “nothing to worry about” position for Black. White has done better overall, and the drill is designed to help you survive the opening with a clear plan instead of letting White’s initiative grow.
What White actually plays most often
The database shows a clear set of most-played continuations, and you should be ready for all of them:
- d4 — 49,523 games; White scores 52.5%
- e4 — 32,945 games; White scores 51.8%
- g3 — 31,592 games; White scores 53.7%

- Nc3 — 13,377 games; White scores 49.3%
- e3 — 6,781 games; White scores 50.6%
The main takeaway is that White has several playable ways to continue, so you should not memorise only one answer. Instead, focus on the broad ideas: meet central expansion, develop sensibly, and keep your position coordinated.
The move to watch for
There is one listed mistake in this position: Nc3 is an inaccuracy and loses about 0.6 pawns; e4 was better. That is very helpful for Black. If White chooses that move, you know the position is not being handled in the best way, so your aim is to stay alert and make the most of the advantage in accuracy rather than forcing anything flashy.
