1.e3 opens the Van't Kruijs Opening, ECO A00. A modest first move that opens lines for the queen and king's bishop but cedes the center. Black gets a free hand to choose the structure.
Strategic Overview
1.e3 is an irregular but not ridiculous first move. It opens diagonals for the f1-bishop and the queen, but it does nothing to contest the center, and crucially it blocks the c1-bishop. Black can answer with almost anything sensible: 1...e5 and 1...d5 stake central claims, 1...Nf6 and 1...c5 keep options open, and 1...g6 sets up a flexible fianchetto that handles multiple White plans. From here, White's game is mostly transpositional. A follow-up c4 reaches the English, d4 leads to Queen's Pawn structures, b3 and Bb2 enter Larsen territory. One quirky possibility is 1...e5 2.e4, arriving at an Open Game with reversed colors and Black to move, which is mostly a curiosity. The real verdict: 1.e3 is passive but solid. Strong players will equalize, but the position stays playable for White as long as the queenside bishop eventually finds a diagonal.
Key Ideas
The recurring motifs below distinguish a confident handler of this opening from a beginner:
- Plan to free the queen's bishop early — The pawn on e3 hems in the c1-bishop. White either commits to b3 and Bb2, plays a later d4 and Bd2, or concedes a tempo with e4. Pick the plan before the bishop becomes a permanent problem.
- Use 1.e3 as a transposition tool — Many White systems include e3 anyway. With c4 you reach the English, with d4 a Queen's Pawn structure, with b3 a Larsen setup. Choose the destination once Black has shown their central preference.
- Let Black overcommit in the center — Because 1.e3 invites ...e5 and ...d5, Black often grabs more central space than they can defend. White's plan is to undermine that center later with c4 or f4, treating the early concession as bait.
Performance Across Rating Levels
The picture changes a lot as you climb the rating ladder. The 1200 bracket has 15,215,982 games (2.26% of all games at that level); White wins 46.6%, Black 49.3%, 4.1% are drawn. Move up to 1800 Elo and the share shifts to 1.06%, with White winning 46.7% versus Black's 48.9%. At the top end (2500+ Elo), popularity is 0.36% with 9.1% draws — a clear sign of how much theory rules the line at master level.
Time Control Patterns
Look at the same opening across time controls and bullet stands out. In bullet, it appears in 2.83% of games (75,114,786); White wins 48.6%. Blitz shows 1.67% adoption across 60,049,175 games, White scoring 46.9%. In rapid, the share rises to 1.72% — 19,052,276 games, White 45.3%. White's score swings 3.3pp across formats, so time control isn't just a stylistic choice here — it shifts the actual results.
Move Diversity and Theory Depth
Move choice is far from uniform in the Van't Kruijs Opening. At 1200 Elo, the top reply is e5, played 53.4% of the time. There are 4 other moves seeing meaningful share, and 78.5% of games stick to established theory. Entropy: 2.29. By 2500, d5 dominates at 27.7% of replies; only 5 viable alternatives remain and 64.8% of moves are theory. Entropy drops to 2.84. Even elite players don't fully agree on the best continuation here, which keeps the position dynamic.
Historical Trends

Main Lines and Variations
After 1.e3, the established follow-ups are:
Each branch leads to a different middlegame character — the resulting pawn structure decides what kind of game you get.
Common Mistakes
- Neglecting development — Extra pawn moves in the opening are tempting, especially when you "know the moves". Developing a piece each turn is the simple correction.
- Playing without a plan — Each Van't Kruijs Opening middlegame demands a specific approach. Decide whether the position calls for attack, manoeuvre, or simplification before reaching for a move.
