The usefulness of pawn majorities

1. e4 e5 2. Ng1f3 Nb8c6 3. Bf1c4 Ng8f6
Two Knights defense
4. d3
4.Ng5 is a more direct, double-edged option here, but White instead chose a quieter, positional move
4... Bf8c5
And so we transpose to something more akin to the Giuoco Piano, a traditionally quieter opening.
5. h3 h6 6. Nb1c3 a6 7. a3 b5 8. Bc4d5 Qd8e7
Ensuring the e5 pawn is held, should Bxc6
9. Bd5xc6
This means Black will have doubled pawns for the meantime, but there will be opportunities to amend this
9... dxc6 10. b4 Bc5a7
Maintains watch over long diagonal
11. Bc1e3
? Perhaps a dubious move. Bb2 may have been more ideal to cover a longer diagonal, potentially attacking e5
11... Ba7xe3
Now White will also have doubled pawns
12. fxe3 c5 13. bxc5 Qe7xc5
Tempo gaining, as the Knight and e3 are both hit
14. Qd1d2 Bc8b7 15. O-O Ra8d8
Getting a rook opposite the Queen is often a good idea
