After 1.d4 Nf6 2.c4 g6, Black signals a King's Indian Defence. By playing 3.g3, White fianchettoes the king's bishop, a quieter but principled approach. Black's reply 3...c6 is a subtle move: it prepares ...d5, challenging the centre immediately, while keeping options open for a later ...b5 or ...e5 break. Black wants a solid, slightly cramped position with good piece play. Your job as White is to keep the centre closed or trade on your own terms, while developing naturally. The statistics show that most players (3,516 out of 4,271 games) choose Bg2 here — and that's the engine's top recommendation too.
The Best Move: Bg2
Stockfish recommends 4.Bg2, continuing the fianchetto plan. After 4...d5, the line goes 5.cxd5 cxd5, and the centre is cleared. White's bishop on g2 eyes the long diagonal — a typical g3-System strength. White scores 49.7% from this position, essentially matching the overall win rate. Other moves like Nc3 (48.6% score) and Nf3 (49.0%) are playable but don't improve your chances. The move b3 has a higher win percentage (60.9%) but is rare, played only 23 games — the sample is too small to draw strong conclusions. Stick with Bg2 for a sound, principled position.
The One Mistake to Avoid
The most common error in this position is pushing 4.d5. This advance is played in only 21 games, and White scores just 33.3%. Stockfish calls d5 an inaccuracy, costing about 0.6 pawns of advantage. The correct alternative was Nf3 (which scores 49.0%). By pushing d5, you give Black a free tempo to develop or expand on the queenside, and you surrender the central tension too early. Unless you have a specific line prepared, avoid this move. The engine line starting with Bg2 keeps the pressure on without overreaching.
What the Numbers Tell You
With a 4.4% draw rate, this opening rarely fizzles into an early peace — you'll get a fight. White wins slightly more often than Black (49.5% vs 46.1%), which matches the tiny engine edge. That +0.22 evaluation means you are slightly better after Black's 3...c6. It's not a big advantage, but it's real. If you play accurately — starting with Bg2 — you'll retain that plus and steer the game toward positions where your space and development matter more than Black's solidity.
