After 1. 2., strong players most often carry on with 3. 4. 5. 6.. You don't fight for the center with pawns right away. First you tuck your king in behind the g2 bishop, then you prepare one specific break: the e2 pawn to e4, against Black's pawn on d5.
2. clears g2, and 3. puts the bishop there, on the long diagonal from h1 to a8. For now it only reaches f3, where your own knight sits, but e4 and d5 are further along that same diagonal, and those are the squares the game will be fought over. Among strong players, 3. comes in 97 of every 100 games. With the bishop out, 4. takes the king to g1, behind the pawns on f2, g3 and h2 and right next to the bishop.
After , 5. and 6. work as a pair. The d3 pawn covers e4 and c4, and the knight on d2 covers the same two squares. That gives you two units on e4, matching Black, who eyes it with the d5 pawn and the f6 knight. This is how you prepare the e-pawn push: once the pawn reaches e4, it attacks d5, the pawn blocking your bishop's diagonal.
With this setup your king nearly always stays on the kingside: you castle short in more than 9 of every 10 games at your level. In 14 of every 100, your opponent castles long, so the kings end up on opposite wings.
At club level the line breaks down early. Against , the most common reply at your level, the setup stays the same: bishop to g2, pawn to d3, castle. What changes is the e7 pawn. If your opponent pushes it to e5 with no protection, as in , take it with 3.. Plenty of players at your level miss that capture, and the mistake notes show what it costs.
