Indian Defense: Normal Variation g6 — Your Guide as White

At its heart, this variation is a battle for the central squares. Black has played ...g6 to prepare Bg7, putting indirect pressure on d4. Your job as White is to seize space and not let Black's fianchettoed bishop become a long-term problem. The engine's top recommendation is to push 4.d5 immediately, grabbing space and closing the centre. The plan is straightforward: after d5 cxd5 Nxd5, you recapture with the knight, then follow up with e4, building a powerful pawn duo in the middle. This approach limits Black's bishop on g7 and gives you a clear structural plus. Remember: in most lines, your central pawns are your strength — don't give them up without a fight.

Stockfish's best continuation is 4.d5. After the sequence d5 cxd5 Nxd5 e4, you've established a strong centre and your knight sits actively on d5. This isn't just engine theory — it's also the most effective practical choice. The most popular reply, Bg7 (played in over 6.9 million games), scores only 48.8% for White — a slightly below-average result. Compare that to Black playing 4...d5 themselves (1.25 million games), where White scores just 44.9%. That tells you something important: if Black copies your central push with ...d5, they're doing something right. Your best weapon is to beat them to the punch with d5 first, taking away squares from their knight and limiting their bishop's scope.

Black has several plausible-looking replies that are actually inaccuracies, each costing roughly 0.6 pawns. If your opponent plays one of these, you can seize a clear advantage. The mistakes, all of which should have been replaced by 4...d5, are: c6 (intending ...d5 later, but you can prevent it), e6 (aiming for a Keres-style setup, but too slow), and c5 (challenging your centre prematurely). In each case, you should respond energetically — maintain your space advantage, develop quickly, and don't let Black equalise. The drill will train you to recognise these moments and capitalise on them.

With nearly 8.7 million games in the database, the stats offer a clear picture. White scores best against e6 (56.7% — a rare but punishing line for Black) and c6 (52.1%). Both of these are inaccuracies, so those high win rates make sense. More surprising: Black's most popular move, Bg7, gives Black a nearly equal score (White 48.8%). And when Black plays d5 — the engine's best move — White actually scores worst at 44.9%. That means most White players don't handle the ...d5 reply well. The solution? Play 4.d5 yourself first, as the engine recommends, and avoid letting Black force you into uncomfortable positions. In this line, initiative and space matter more than memorising long variations.
