The King's Indian Defense is one of Black's most popular answers to 1.d4, and the move 3.Nc3 is the most principled way to meet it. By developing the knight to c3, you maintain your pawn grip on the centre (c4 and d4) while keeping all your options open. Black has just played 3...d6, supporting a future ...e5 break and preparing to fianchetto the king's bishop. At this moment, the database shows over 2.2 million games have reached this exact position, making it a well-trodden battleground. Your task is to choose a continuation that maximises your plus — and the statistics reveal which path delivers. Across all games from here, White wins 48.7% of the time, with 4.1% draws and 47.2% Black wins. The gap is narrow, but the right move can tilt the odds your way.
The Engine's Top Choice: 4.e4
Stockfish recommends 4.e4, pushing your central pawn duo to d4 and e4 — the classic 'big centre' that directly challenges Black's setup. After 4.e4, the engine's predicted continuation is e4 Bg7 Be2 e5, leading to a standard King's Indian mainline where White's space advantage is clear. This move has been played in nearly a million games (991,258), and White scores 49.8% — your best winning percentage among the major options. The idea is simple: seize space in the centre, develop naturally, and dare Black to prove their counterplay is real. If you like positions where you have a clear spatial plus and your opponent must generate action on the kingside, 4.e4 is your move.
What the Other Moves Tell You
Not every developing move is equal here. The second-most popular choice, 4.Nf3 (531,726 games), scores 48.0% for White — slightly below the overall average. The pinning 4.Bg5 (349,313 games) brings 48.5%, close but still a tick below 4.e4. The quiet 4.e3 (128,627 games) drops to 45.7%, a noticeable dip that suggests you are giving Black too much leeway. Meanwhile 4.Bf4 (101,667 games) yields 47.3%, and the fianchetto 4.g3 (47,160 games) scores 50.0% — decent but rarely chosen. The pattern is clear: the most ambitious central move, 4.e4, gives you the best results, while more timid set-ups let Black equalise more easily. Use this data to trust your central push.
Your Typical Middlegame: Space vs. Counterplay
After 4.e4 Bg7 Be2 e5, you reach a thematic King's Indian middle game. Your structure (pawns on c4, d4, e4) gives you a space advantage, especially on the queenside and in the centre. Black will typically challenge you with ...e5xd4 or ...e5-e4 at some point, and may later aim for ...f5 or ...g5 breaks on the kingside. Your plans often involve a queenside expansion with b4-b5, or simply consolidating and preparing to meet Black's attack. The engine's +0.63 evaluation reflects your extra space and easier development — but Black has dynamic counterchances. Stay alert to kingside threats, keep your king safe (often castled short), and use your space to outplay them positionally. The drill will help you practise these exact decisions.

Frequently asked questions
Is 4.e4 the only good move against the King's Indian Defense?
No, but it is the engine's top recommendation and statistically your best bet, scoring 49.8% across nearly a million games. Moves like 4.Nf3 and 4.Bg5 are perfectly playable, but they score slightly lower (48.0% and 48.5%) and give White a smaller edge.
What does +0.63 mean for me as White?
The engine evaluates the position at +0.63, which is a small but consistent advantage for White. In practical terms, you have a little more space and slightly easier development. It does not mean you are winning — you still need to play well — but you start the middle game with a real plus.
Why does 4.e3 score so poorly for White?
4.e3 is a solid but passive move that scores only 45.7% — below Black's winning percentage from this position. By refusing to fight for the full centre, you allow Black to complete their King's Indian setup without any pressure. The statistics confirm that this caution costs you.
What is the engine's predicted line after 4.e4?
Stockfish suggests 4.e4 Bg7 Be2 e5 as the best continuation for both sides. This leads to a typical King's Indian mainline where White has the centre and Black prepares kingside counterplay. You can practise this exact sequence in the interactive drill below.
