By playing 1.c4 and 2.Nf3 you've avoided symmetrical openings and kept Black guessing. After 3.g3 your plan is straightforward: develop the bishop to g2, castle quickly, and prepare to challenge Black's centre with d4. The engine's best move here is actually ...d5 for Black — a direct central strike — but your opponent will rarely find it over the board. Instead, most club players reach for natural developing moves, and that's where your small edge (+0.34, meaning White is slightly better) can grow. Black's most common replies — g6, Nc6, and e6 — all allow you to seize space with a well-timed d4, opening lines for your fianchettoed bishop.
How to Meet Black's Most Popular Replies
The database of 68,137 games reveals Black's top three moves and your excellent odds in each: - 3...g6 (21,651 games): Black fianchettoes too. Your winning percentage as White is 51.7%. Push d4 or build pressure on the dark squares — your bishop on g2 will eye the long diagonal while Black's kingside is slightly airy. - 3...Nc6 (20,552 games): A natural developing move. White scores 51.6%. Again, d4 is thematic. After d4 cxd4 Nxd4, your knight sits actively and Black has no easy counter. - 3...e6 (8,768 games): Black prepares d5. White scores 51.5%. You can allow ...d5 and recapture with the pawn, keeping a flexible structure, or play d4 before Black locks the centre. In every line your winning percentage hovers around 52%, with draws under 5% — meaning you convert more often than not when you play actively.
The One Move You Want to Play
Over and over, d4 is the engine's recommendation and the thematic continuation. In the FACTS the engine's best line runs: 3...d5 4.cxd5 Nxd5 5.Bg2. That's Black's best try, but even then you finish with a harmonious setup: bishop on g2, knight on f3, and a half-open c-file. Most opponents won't play 3...d5 — only about 6,247 games reach it — so when they don't, you should nearly always aim for d4 yourself. It's the break that activates your pieces and puts the question to Black's centre. If you hesitate, Black can equalize with a timely ...d5 of their own. The principle is simple: in this fianchetto system, d4 is your main lever.
Reading the Numbers
Let the stats guide your confidence. Across 68,137 games at this exact position: - White wins 52.1% - Draws 4.9% - Black wins 43.0% That's a strong practical result. Even Black's best-scoring reply — 3...d6, with White winning 53.6% — plays right into your hands, since Black's passivity lets you build a kingside attack or a central pawn roller. No matter which of the six most-played moves Black chooses, your winning percentage never dips below 51.5%. The +0.34 evaluation is a real edge — now it's up to you to convert it.

Frequently asked questions
What should I do if Black plays 3...d5 immediately?
That's actually Black's best move according to the engine. The line is 3...d5 4.cxd5 Nxd5 5.Bg2. You come out with a small advantage and a pleasant position. Your knight on f3 can eventually jump to e5 or d4, and your bishop on g2 targets the centre. Just avoid rushing — develop naturally and you'll keep the edge.
How important is it to fianchetto with g3 and Bg2?
Very important. The whole point of the King's Knight Variation is to control the long diagonal and support a later d4 break. Without Bg2, your position lacks bite. The g3 fianchetto is not just a stylistic choice — it's the backbone of your strategy in this line.
Why does Black rarely play 3...d5 despite it being the engine's top move?
Because it feels committal. Many amateur players prefer to develop (g6, Nc6) or prepare d5 with e6 first. The direct 3...d5 opens the centre early, which White's setup is ready for. So most opponents avoid it, which is good news for you.
