English Opening: Anglo-Indian Defense, King's Knight Variation – e6 (White)

By playing 3.d4 you claim a share of the centre and set up a flexible pawn duo on c4 and d4. Black's knight on f6 already eyes e4, and their e6 pawn supports a quick ...d5 challenge. The engine's +0.38 evaluation reflects White's comfortable space advantage and the possibility of developing naturally with moves like Nc3 or Nbd2, g3, or even Bg5. You are not crushing anyone yet — but you have the kind of edge that rewards understanding over memorisation. The most popular Black move, d5 (over 1.2 million games), leads directly into a Queen's Gambit Declined style struggle where your slight space advantage persists.

Stockfish's preferred reply for Black is 3...Bb4+, pinning your knight and provoking a commitment. The engine's suggested continuation runs 4.Nbd2 b6 5.Qc2. By interposing the knight on d2, you avoid doubled pawns on f3 and keep your c4 pawn intact. Black often follows up with ...Bb7 and ...d5 anyway, transposing to a known structure where you can castle queenside or kingside depending on taste. In the database Black plays Bb4+ in over half a million games, and White scores a solid 51.3% — slightly above the overall average, suggesting that handling the check well is rewarding.

Across 2,892,104 games, the numbers tell a clear story. Black's most common move, d5, gives White a 50.2% score — almost identical to the baseline. The most punishing Black move (from White's perspective) is actually c6 — only 69,078 games, but White wins 53.0% of them. That sharp jump suggests many players meet 3...c6 with an imprecise plan. On the flip side, Black's b6 drops White's winning percentage to 48.7%, making it the reply where you need to be most careful. The rarest of the top six, Be7 (161,486 games), yields White's second-best score at 52.0%. Overall, the 4.2% draw rate confirms this is a fighting opening — most games end decisively, and you are winning more often than Black.

While no single error is listed for this exact position, the numbers hint at the biggest trap: over-pressing. With a +0.38 edge, you do not need to force a win in the opening. Players who lash out with an early g4 or a speculative piece sacrifice often hand Black the counterplay that brings their score down. A more subtle mistake is misplacing the queen. After Black plays Bb4+, some White players try to avoid the pin with 4.Qc2? — a blunder that blocks your own light-squared bishop and weakens your control of d4. The engine's 4.Nbd2 is cleaner. Stick to simple developing moves, castle early, and let the position's natural advantages do the work.
