White - Steinitz
Black - von Bardeleben
Giuoco Piano (Hastings 1895)

1  e4               e5
2  Nf3             Nc6
3  Bc4             Bc5
4  c3
So far, all of the moves have been natural developing moves. White's fourth move does nothing much for development (in this game White's queen does not go to b3) but is all about central control and the support of a pawn on d4.
