The plan, from masters' games
Everything in this opening revolves around the g2 square. 1.g3 clears that square and 2.g2 puts your light-squared bishop there, on the long diagonal running from h1 to a8. Among players rated over 2200 online, the bishop lands on g2 in 96 games out of 100. You castle short behind it, and then the d-pawn steps forward to contest e4. The strong-player line, 1…d52.g22…f63.f33…e64.O-O4…e75.d3, follows exactly that order. Your results with it hardly depend on rating: whichever band you're in between 900 and 1700, you score 51 in 100.
After 1…d5, 2.g2 hits the d5 pawn through f3 and e4, which are both empty. Its only defender is the queen on d8, so 2…f6 adds a second one and also covers e4, the central square on your diagonal. 3.f3 covers e5 and d4 and clears the way between your king and the h1 rook. With the knight on f3, the e7 pawn can no longer land on e5 without hanging. 3…e6 props up d5 with a pawn: your bishop now runs into a pawn with three defenders, and your opponent's f8 bishop gets e7 to come out. 4.O-O puts your king on g1, shielded by the f2, g3 and h2 pawns and by the g2 bishop. 4…e7 gets your opponent ready to castle. After 4.O-O, 67 strong players in 100 choose it; at your level, 21 do. 5.d3 rounds off the sequence: the pawn covers e4, prepares to push the e-pawn there to hit d5, and opens the diagonal for your c1 bishop all the way to h6.
Five of the six mistakes on this page share one root: you let your opponent set up pawns on d5 and e5. After 2…f6, 3.b3 leaves e5 unguarded and allows 3…e5. That's why 3.f3 comes before anything else. The same logic holds against 2…c6: 3.f3 covers e5 before 3…e5 can arrive, while 3.e3 leaves the square free for it. Against 1…e5, which is what you'll face most, the square to watch is d5, and the c-pawn does that job: 2.c4, or 3.c4 if you've already played 2.g2, hits d5 before your opponent's pawn can get there. With a pawn on c4, your g2 bishop keeps its view down the diagonal instead of staring at a pawn on d5.

g2Inaccuracy
After 1…e52.f32…c6, 3.g2 lets 3…e4 kick your f3 knight, which heads back with 4.g1. Your opponent props up that pawn with 4…d5 and, after 5.d3, with 5…f5 before 6.dxe4. 46 in 100 play it. At your level it goes unpunished: you score 46.5 with it and 45.3 with 3.c4.

b3Inaccuracy

20 in 100 play it in this position. It gives away 0.9 pawns of advantage. It scores 50.1%; c4 scores 52.2%.
b3Inaccuracy
Against 1…e52.g22…f6, 3.b3 runs into the same d5 problem. Your opponent goes 3…d54.d34…d65.d25…O-O6.a3: pawns on d5 and e5, the d6 bishop holding e5 and the king already castled. 21 in 100 play it. At your level it often goes unpunished: you score 49, against 51.7 with 3.c4.
22 in 100 play it in this position. It gives away 0.7 pawns of advantage. It scores 49.0%; c4 scores 51.7%.
b3Inaccuracy

3 in 100 play it in this position. It gives away 0.8 pawns of advantage. It scores 49.3%; c4 scores 54.3%.
e3Inaccuracy

At your level it often goes unpunished: you score 51.1, against 52.8 with 3.f3, which covers e5 in time.
