Zukertort Opening: Old Indian Attack — 3.g3
After 1.Nf3 d5 2.d3 Nf6, White chooses the quiet fianchetto with 3.g3. This is the Zukertort Opening: Old Indian Attack, and it leads to a slow, manoeuvring struggle where space matters more than tactics. You are playing White, and the engine rates the position at -0.22 — essentially dead level. That means you have nothing to fear, but you also have no immediate edge to push. The drill below will test you against the most popular and challenging replies Black can throw at you from this modest starting point.

This opening is about outplaying your opponent in a closed, strategic game rather than blowing them off the board. By fianchettoing your king's bishop, you control the long diagonal and keep the centre flexible. You are not staking a claim to e4 or c4 immediately — instead, you wait for Black to commit to a pawn structure and then find the best square for each piece. The statistics bear this out: across nearly 192,000 games, White wins 48.7% and Black wins 46.6%, with only 4.7% draws. That low draw rate tells you the position stays imbalanced and fighting all the way into the middlegame. If you enjoy out-planning opponents in a quiet but tense atmosphere, this is your system.
The Engine's Roadmap: c5
Stockfish's top choice for Black is 3...c5, planning to meet 4.c4 with 4...d4 and then 5.e3 — a typical Benoni-ish structure where Black clamps down on the centre. This is the critical test of your setup. If you have never studied this line, the natural 3...c5 can feel annoying because Black immediately challenges you to find a plan. In practice, Black plays 3...c5 in just under 21,000 games, and White scores only 46.9% — so this is the reply that gives you the most work to do. The engine's suggested continuation (c5 c4 d4 e3) shows a typical fight for the d4-square. Against this, you should aim to develop your pieces harmoniously and not rush to recapture in the centre.
Facing the Most Popular Replies
Black's most common move by far is 3...Nc6 (over 58,000 games), where White scores 48.3% — a normal, balanced result. The knight doesn't threaten much yet, so you can continue with standard development: fianchetto your bishop, castle, and bring your pieces to natural squares. The second-most popular, 3...e6 (over 29,000 games), is actually the best-scoring reply for you: White wins 51.0%. Black's pawn on e6 hints at a French-like structure, and you can prepare e4 or c4 depending on how the game goes. Other common moves include 3...Bg4 (pinning the knight), 3...g6 (a mirror fianchetto), and 3...Bf5. Against all of them, your job is the same: get your king safe, finish development, and only then look for a break in the centre. Black's 3...Bg4 is tricky but White still scores a respectable 48.6%.
Common Mistakes to Avoid
The biggest danger in this opening is misjudging the pace. Because the position looks quiet, many White players drift — they develop aimlessly and let Black seize the centre with ...e5 or ...c5 followed by ...d4. Another typical error is fianchettoing but then forgetting to use the bishop: a fianchettoed bishop that never fires down the long diagonal is a wasted asset. A third pitfall is playing c4 too early, before you have enough support for the d4-square. If Black plays ...c5 and you push c4, you need to be ready for ...d4, which can leave your knight on f3 slightly misplaced. Keep your pawn breaks patient, develop your queen to e2 or c2, and let the game come to you.

Frequently asked questions
Is the Zukertort Opening: Old Indian Attack good for beginners?
Yes — it is a solid, principled system with few forced lines. After 1.Nf3 d5 2.d3 Nf6 3.g3 you avoid heavy theory and focus on general development and pawn structures. White scores 48.7% at the club level, which is perfectly healthy for a system that is easy to learn.
What is Black's best reply to 3.g3?
According to the engine, Black's strongest move is 3...c5, scoring 53.1% for Black in practice (White wins only 46.9%). The engine suggests 4.c4 d4 5.e3 as a typical continuation. Still, the position stays close to equal — the evaluation is only -0.22, so there is no reason to panic.
Why does the Zukertort Opening have so few draws?
Only 4.7% of games end in a draw from this position, which is very low compared to many main-line openings. The closed, flexible nature of the position means that imbalances — like one side getting a better pawn structure or a more active bishop — persist into the middlegame and lead to decisive results.
Should I play c4 or e4 after 3.g3?
Both are possible, but timing matters. If Black plays ...c5, you may answer with c4 to fight for the d4-square. If Black plays ...e6, you can often prepare e4. In general, wait until your king is castled and your pieces are developed before committing to a central pawn break.
