In a game from the same meeting, Anderssen took the Black side of this opening and played 5....Bg7 6.d4 Ne7 7.g3 fxg3 8.Kg2 Qb6 9.hxg3 Qg610.Nf3 h6 11.Rf1 Rf8 12.e5? (Better was 12.Be3) 12....g4 13.Bd3? (Necessary was 13.Nd2) 13....gxf3+ 14.Qxf3 Qb6 15.Qg4 Rg8! 16.Qf4 Qe6 17.Bd2 d5 18.Rh1 Bd7 19.Ne2 N8c6 20.b3 O-O-O with the much better game for Black.
A better idea was 15....Nc6.
