The 2^nd Black move is not a repetition (the bK does not come from the same square).
The orthogonal-diagonal correspondence is excellent.

The cycle of white moves ABCD at the 2^nd and 3^rd moves is all the more impressive as the motivation for White's 2^nd move is the same (deflection of bBd4). The final aesthetic blow is the star of the black Bishop.
