The English Opening: King's English Variation, Smyslov Defense — Playing as Black
Welcome to the Smyslov Defense, a cunning way for Black to meet the English Opening. After 1.c4 e5 2.Nc3 d6 3.Nf3 Bg4, you've already pinned the knight and asked White a tricky question: how do they deal with the pressure on f3? The statistics show this is no pushover — across over thirty thousand games, Black scores 41.9% and draws 4.2%, which is respectable for a sideline. The engine rates the position +0.83 in White's favour, so you must be realistic: you are clearly worse, but the position is rich in imbalance and winning chances if your opponent doesn't know the best reply. The drill below will sharpen your instincts in this exact tabiya.

The Smyslov Defense is about gaining dark-square control and provoking a concession. Your bishop on g4 pins the f3-knight to the queen, making it awkward for White to develop naturally with d4 or e3. If White plays timidly — pushing pawns that don't challenge you — you can follow up with ...Nd7, ...c6, and a solid kingside structure. The trade-off is time: you've spent two moves on a bishop that might get chased by h3, but in return you've avoided well-trodden open lines like 1.c4 e5 2.Nc3 Nc6 where White's plans are well known. Your job here is to keep the centre fluid and wait for White to overreach.
The Critical Moment: White's Best Reply
Stockfish's top choice is d4, establishing a strong pawn centre. The engine's suggested continuation is d4 Nd7 g3 c6. This shows that even when White plays centrally, you can respond solidly: develop the knight to d7 (keeping the c8-h3 diagonal open), meet g3 with ...c6 to bolster the d5-square, and prepare ...exd4 followed by ...Bxf3 if appropriate. Against d4, your score drops slightly (White scores 57.0% from 4,330 games), so it's a tough test — but you're not aiming for equality; you're aiming to outplay a less-prepared opponent in a position they might misjudge.
Which White Replies Give You the Best Chance?
Not all of White's continuations are equally dangerous. The most common move, e3 (8,247 games, White scores 56.4%), is modest but solid — White develops slowly, giving you time to complete development. The critical opportunities come when White errs with one of the known inaccuracies. h3 (4,021 games) is White's worst-scoring option at 49.8% — after h3 you can retreat to h5 or exchange on f3, and the h3 pawn can become a target later. e4 (3,894 games, White scores 49.5%) and g3 (5,607 games, White scores 55.4%) are both flagged as inaccuracies that lose ground compared to d4. Specifically, e4 loses about 0.8 pawns of advantage and g3 loses about 0.6 pawns of advantage — both are mistakes that you should be ready to punish.
How to Punish White's Inaccuracies
If White plays g3, preparing Bg2, you should know that this is a sizeable error. With the centre still open, fianchettoing is too slow. Your plan: consider ...exd4 immediately to open lines, followed by ...Bb4 to pressure the c3-knight, or simply ...Nd7 and ...c6 as in the main line — but with White's bishop on g2 rather than d3, your counterplay on the light squares (like ...c5 later) gains extra sting. Against e4, White weakens the d4-square and blocks the c1-bishop. Here you should strike back in the centre with ...exd4 Nxd4 ...Bxe4? No — be careful; the e4 pawn is protected by the knight on c3. Instead, consider ...Nd7 followed by ...g6 and ...Bg7, targeting the d4-pawn. The key is to treat these inaccuracies as a green light to seize the initiative, not just equalise.

Frequently asked questions
Is the Smyslov Defense a good opening for Black against the English?
It is a playable but slightly worse option. Stockfish evaluates the position at +0.83, meaning White has a clear edge. In practice, White scores 53.9% across over 30,000 games, but Black still wins 41.9% — so you'll get plenty of winning chances, especially if White doesn't know the best reply (d4).
What should Black do if White plays h3 in the Smyslov Defense?
h3 is actually White's worst-scoring move in the database (49.8% from 4,021 games), so this is good news for you. You can retreat your bishop to h5, preserving the pin, or exchange on f3 to double White's pawns. The h3 pawn can become a long-term weakness, so keeping the bishop active is usually best.
Why is g3 considered an inaccuracy for White here?
The engine says g3 loses about 0.6 pawns of advantage compared to the best move d4. The problem is that fianchettoing is too slow when the centre is still fluid — White should claim space with d4 first. After g3, you can challenge the centre with ...exd4 or develop quickly with ...Nd7 and ...c6, and White's kingside fianchetto doesn't pressure anything yet.
What is the main idea behind Black's setup with ...d6 and ...Bg4?
The pin on the f3-knight makes it hard for White to play d4 immediately without preparation (since ...Bxf3 would damage White's pawn structure). You also keep the pawn on e5, controlling d4 and f4. The setup aims to provoke White into either a slow build-up (e3, g3) or a positional concession, while you prepare ...Nd7, ...c6, and a flexible kingside.
