King's Indian Defense: Normal Variation, King's Knight Variation — c5

This position is all about central space. By playing 4.d5 you've locked the centre and claimed the d5-square as a permanent outpost. White's plan is straightforward: develop your pieces to active squares, castle kingside, and then decide whether to push on the queenside (with b4 and a4) or prepare a kingside attack with e4 and eventually f4. The engine evaluation (+0.73) confirms that you already have a comfortable edge — you're not risking anything, and Black is the one who has to find a way to generate counterplay.

The most popular reply — played in over 17,000 games — is 5...Bg7, continuing the King's Indian setup. The engine's best continuation runs 5...Bg7 6.Nc3 O-O 7.e4. That's exactly the kind of natural development you want: bring the knight to c3, castle, and push e4 to seize even more centre. White scores 47.3% after 5...Bg7 (with 3.8% draws), which is solid but not dominating — the position demands accurate play. Keep your pieces active and remember that Black will try to strike back with ...e6 or ...b5; stay alert and you'll maintain your advantage.

Here's a number that might raise your eyebrows. Across all 36,677 games from this position, Black actually wins 50.8% of the time, while White wins 45.4%. That's unusual for a position the engine rates as clearly better for White (+0.73). What gives? The answer is that this line requires precision. Black's kingside attacking plans can be dangerous if you play passively or misplace your pieces. The engine sees the objective truth — White is better — but human games show that Black's counterplay (especially the classic King's Indian kingside attack) scores well when White isn't careful. Don't let the stats scare you; they're a reminder to stay sharp.

The second most-played move after 5...Bg7 is 5...b5 — a sharp pawn sacrifice Black uses to stir up immediate counterplay. White scores only 42.2% after this move, making it the trickiest reply to face. The key is to know how to handle it: don't grab the pawn carelessly if it weakens your position. Similarly, 5...d6 (4,192 games, White scores 46.9%) and 5...e6 (2,872 games, White scores 44.7%) are solid developing moves where Black aims for the typical ...e6 break or ...Bg7 set-up. Against all of these, the engine's guidance is clear: develop naturally, keep your centre intact, and don't rush. The drill will train you to meet each reply with confidence.
