Your setup is clean: pawns on d4 and c4 give you a space advantage in the centre, and the fianchetto with Bg2 will let your bishop eye the long diagonal. Black's ...e6 has already committed to a stonewall-ish or Leningrad-style setup, but they haven't declared their exact plan yet. The most common move here is Be7 (26,860 games), a natural developing move that keeps the position solid. Right behind it is Bb4 (26,016 games), pinning your knight and creating more immediate tension. Your task is to handle both confidently — the engine's top recommendation is Bb4, and we'll look at why that's Black's best try. From your side, you're slightly better: the space and the coming Bg2 give you a comfortable edge, but you still need good moves to keep it.
The Engine's Best Continuation — What Black Wants
Stockfish's suggestion from the diagram is Bb4, and the full line runs Bb4 Bd2 O-O Bg2. Black pins your knight on c3, preventing you from advancing d5 too quickly and threatening to double your c-pawns after ...Bxc3. Your reply Bd2 is simple and strong: it breaks the pin, develops, and keeps the option of playing Nge2 or Nf3 later. After Black castles, you develop with Bg2, completing the fianchetto. Black hasn't gained anything tangible — the pin is gone, your structure is sound, and your pieces are coming out naturally. If you meet Bb4 with Bd2, you're following the engine's path and maintaining your small plus. The other popular move, Be7, invites you to continue with Bg2 and Nf3, building a classical Catalan-style setup.
The Statistics — What 80,000 Games Reveal
The numbers tell a clear story about which Black replies are dangerous and which are not. Here are the most-played moves and your scoring chances: - Be7 (26,860 games): White scores 52.4% — solid, normal chess. - Bb4 (26,016 games): White scores 52.3% — just as reliable, and the engine's pick. - c6 (10,340 games): White scores 48.6% — this is trickier; Black prepares ...d5, and your win rate dips slightly. - d5 (7,183 games): White scores 49.7% — the Stonewall setup, a common Dutch approach. - b6 (2,751 games): White scores a whopping 60.2% — this is the outlier. Black's last move is also marked as a mistake, losing roughly 0.7 pawns. - d6 (1,999 games): White scores 56.2% — another subpar option for Black. The big takeaway: if Black plays b6, you've already won the opening battle.
Punishing Black's Worst Mistake — When You See b6
The move b6 is flagged as an inaccuracy, losing about 0.7 pawns of equity. Black tries to fianchetto their queen's bishop, but in this position it's too slow and leaves the dark squares vulnerable. The engine says Black should have played Bb4 instead. As White, you should treat b6 as a green light to take the initiative. Your development continues naturally — Bg2, Nf3, O-O — but you can also consider an immediate d5 break or putting pressure on the queenside with a quick a3 and b4. With a 60.2% win rate for White, this is the line you want to see. Keep in mind that c6 (48.6%) and d5 (49.7%) are more challenging for you — those positions require careful play and a bit of patience, as Black often sets up a sturdy centre.

Frequently asked questions
Is the Dutch Defense good for Black?
Statistically, Black scores around 43.7% from this exact position after 4.g3 in the Queen's Knight Variation with e6. While the Dutch is a legitimate opening, the numbers show that as White you have a clear scoring advantage — 52.2% wins — and the engine gives you a small but stable +0.38 edge. Black can be dangerous if you're unprepared, but with solid play you should outperform.
What should White do against the Stonewall setup with ...d5?
When Black plays d5 after 4.g3, they're aiming for the Stonewall Dutch structure with pawns on d5, e6, and f5. This is a solid but somewhat rigid setup. Your plan is straightforward: fianchetto with Bg2, develop your knight to f3, castle, and then look to undermine the centre with moves like b3 and Ba3 or an eventual e3 and exd4 break. White scores 49.7% here — it's balanced, so patience is key.
Why is b6 a mistake in this line?
The move b6 loses roughly 0.7 pawns compared to the best continuation (Bb4). It's too slow — Black wastes time preparing ...Bb7 while you develop freely. The statistics back this up: White wins 60.2% of games after b6, your highest win rate against any common Black reply. If your opponent plays b6, focus on natural development and you'll likely get a comfortable edge.
How should White handle the pin with ...Bb4?
Black's most challenging move is Bb4, pinning your knight on c3. The engine's recommended reply is Bd2, breaking the pin and developing. After Black castles, you continue with Bg2. The pin never becomes dangerous because you can always recapture with the bishop if Black takes on c3. White scores 52.3% against Bb4, so you're still doing well — just don't panic and push d5 prematurely.
