The Van't Kruijs Opening: d5 – Why 1.e3 Might Be Smarter Than It Looks

With 1.e3 and 2.d4, you build a pawn duo on e3 and d4 that supports central control while keeping your options open. Unlike 1.d4 or 1.e4, this setup doesn't commit to an early bishop move or a kingside attack. Black's most common replies in the database are Nf6 (over 8.8 million games) and Nc6 (over 8.3 million games), both natural developing moves. The engine's favourite response is e6, leading to a French-like structure after Nf3 Nf6 Bd3. Your core idea is simple: develop solidly, keep the centre closed or half-open, and look for chances to outplay your opponent in the middlegame. The statistics show this works — you score a healthy 50.2% against the most accurate Black replies.

Here are the top replies you'll face and what the database says about them. Each number comes from the Lichess database of over 35 million games at this position (1.e3 d5 2.d4). The percentages are White's scoring rate (wins + half draws):- Nf6 (8.8m games, White scores 48.8%) — The most common move. Black develops and threatens …Bg4 or …e6. You can meet it with Nf3 or Bd3, keeping your options open.- Nc6 (8.4m games, White scores 50.2%) — Equal in popularity and effectiveness for White. This often leads to a Queen's Pawn structure where …Bf5 or …Bg4 can be annoying. Your slight plus is real here.- e6 (6.6m games, White scores 50.2%) — The engine's top choice. Black solidifies the centre. After Nf3 Nf6 Bd3, you have a comfortable French-type position with easy development.- Bf5 (4.8m games, White scores 49.0%) — Pinning the e-pawn is a natural idea, but your c4 break or quick Nf3-Nbd2 can challenge the bishop.- c5 (2.1m games, White scores 47.7%) — This is Black's most aggressive try, attacking your centre immediately. Your score dips below 50% here, so be ready. Meet it with c3 or Nf3, keeping the centre solid.- c6 (1.8m games, White scores 49.6%) — Preparing …Bf5 or …e6. A flexible response.Overall, you score above 48% against every popular reply — a sign that White is fully OK in all lines.

The numbers are reassuring for a White player: 49.5% wins, 4.4% draws, 46.1% losses. That win percentage is healthy for any opening, especially one that starts with a quiet first move. But here's what really matters: your opponent is more likely to make a mistake than you are. The engine evaluation of +0.19 (a tiny edge for White) means you are slightly better — not a forced win, but a real pull. Many club players hate facing offbeat openings because they aren't sure how to punish them. Your job is simple: develop naturally, don't overreach, and let your opponent's uncertainty do the work. The most accurate Black move (e6) leads to positions where you can outplay them with straightforward development.

The best way to learn the Van't Kruijs is to play it against an engine that adapts to your level. The drill below starts from the position after 1.e3 d5 2.d4, with Black to move. You'll see the most common replies and get immediate feedback on your moves. Focus on developing your kingside pieces (Nf3, Bd3) and castling quickly. If Black plays the engine's best move e6, follow the continuation Nf3 Nf6 Bd3 — you'll reach a comfortable French-type setup where White has easy play. Don't worry about memorising every line; the engine will guide you.
