Facing the King's Indian Defense: Bg5 as White
Against the King's Indian Defense, most White players expect to face the main lines with Bg2 and Nf3. But when your opponent throws 3.Bg5 at you, followed by the cheeky 3...Ne4, you've left the textbook behind. Black's knight jumps into the centre, attacking your bishop and forcing you to make a decision on move four. The statistics are sobering: across over 17,000 games, Black scores a massive 56.3% from this position, while White only manages 40.1%. But don't panic — the engine says the position is dead level. You just need to know which move keeps the balance. Let's find it in the drill below.

After 1.d4 Nf6 2.c4 g6 3.Bg5 Ne4, White has several plausible moves — the Lichess database shows no fewer than six options with significant play. But the engine is crystal clear: only one move keeps the game equal. Stockfish rates the position at -0.15, which is essentially dead level. However, that tiny number only holds if you play the right move. The most popular choice, Bf4, is actually the engine's top pick, and it scores a respectable 42.3% for White across 6,631 games. The second most-played move, Bh4, is played over 3,500 times — but the engine calls it an inaccuracy that loses about 0.6 pawns. That's the difference between equality and a small but real edge for Black.
Why Bh4 Is a Trap for White
It's understandable why Bh4 is popular: you retreat the bishop to a safe square, keeping the pin on the knight. But in this exact position, Bh4 is a known mistake. The engine identifies it as an inaccuracy, losing roughly 0.6 pawns compared to Bf4. Black can quickly organise ...c5, challenging your centre, and the bishop on h4 ends up misplaced. Worse yet, the statistics show that even though Bh4 scores 45.3% for White (better than Bf4's 42.3%), this is likely because stronger players choose Bf4 more often, drawing out the opponent's skill. Trust the engine here: Bh4 lets Black off the hook and gives them a pleasant position.
The Engine's Best: Bf4 and the Plan
The top engine move is 4.Bf4, and Stockfish recommends the following continuation: Bf4 c5 Qc2 f5. White's idea is simple and strong. After Bf4, the bishop is active on the long diagonal, eyeing the queenside. Black typically strikes with 4...c5, challenging your centre. Your reply Qc2 is key — it defends the d4 pawn indirectly and also eyes the e4 square. If Black then plays ...f5, as the engine line shows, Black's kingside looks a bit rigid, and White has a small but comfortable edge in development and space. The position remains level, but you have the cleaner plan. In the drill, try this exact sequence and see how the engine responds.
The Worst Option: Qc1 and Nf3
Two other moves deserve a warning. Qc1 is played 456 times in the database, but the engine flags it as an inaccuracy costing White about 0.5 pawns. Retreating the queen to c1 loses time and doesn't improve your position meaningfully. Even worse is Nf3, played over 3,000 times but scoring a miserable 34.8% for White. That's the worst score of any reasonable move — you're basically handing Black a 56% win rate by developing normally. The knight on f3 blocks your bishop and doesn't challenge Black's ...Ne4 at all. Stick to Bf4, and you'll avoid the worst statistical outcomes.

Frequently asked questions
Is the King's Indian Defense: Bg5 a good surprise weapon for Black?
Statistically, yes — Black scores 56.3% from this position in Lichess games, which is excellent. However, the engine evaluation says the position is dead level if White plays accurately (4.Bf4). So it's a practical weapon: Black gets winning chances if White doesn't know the correct response, but with correct play the game is equal.
What is the best move for White against 3...Ne4 in the Bg5 line?
The engine's top move is 4.Bf4, and it's the only move that keeps the position near equal. The recommended continuation is 4.Bf4 c5 5.Qc2 f5. Other moves like Bh4, Qc1, or Nf3 are either inaccuracies or give Black much better practical chances.
Why is Bh4 considered a mistake here?
Stockfish identifies Bh4 as an inaccuracy that loses roughly 0.6 pawns. While the bishop retreats to a safe square, it ends up slightly misplaced, and Black can quickly organise ...c5 to challenge your centre. Bf4 is simply a more active and principled square for the bishop.
What is Black's plan after 4.Bf4 in the King's Indian Bg5 line?
Black's most common response is 4...c5, directly challenging the d4 pawn. After White plays 5.Qc2 (defending d4 and eyeing e4), Black often follows up with ...f5, locking the centre and preparing kingside play. The resulting position is roughly equal but both sides have clear plans.
