I have some problem regarding an opening and it's on my forum.  Can you help?

That is an English opening by transposition.

Black has played 1...e5, which is the best move against either 1 c4 or 1 e4.

In Carsten Hansen's "Guide to the English Opening 1...e5", p. 239, he notes "2 e4? is premature: 2...Bc5 3 Nc3 d6 4 g3 Nc6 5 Bg2 f5 6 d3 Nf6 and White already has problems getting his pieces developed as the f2-pawn is quite vulnerable, Colin-Gulko, St Martin 1992.

The complete game:

Colin Mancera, Cleto-Gulko, Boris 2560 

1 c4 e5 2 e4 Bc5 3 Nc3 d6 4 g3 Nc6 5 Bg2 f5 6 d3 Nf6 7 Nh3 0-0 8 0-0 h6 9 Qd2 fxe4 10 Nxe4 Nxe4 11 dxe4 Be6 12 Kh1 Qd7 13 Ng1 Bxc4  0-1
