Many amateurs don't understand that both sides, not one, determine the opening. They think if they play d4 and Bf4, it is a london system, or if they play 1...d5, it is automatically a Queen's Gambit or Scandinavian.
Well, 1.d4 d5 2.Bf4 c5 3.e3 cxd4 4.exd4 is not a London - It's an Exchange Caro-Kann (1.e4 c6 2.d4 d5 3.exd5 cxd5 4.Bf4 is the exact same position).
1.e4 d5 2.exd5 Nf6 3.c4 c6 4.d4 cxd5 5.Nc3 is not a Scandinavian. It is a Caro-Kann, Panov-Botvinnik Attack.
Just like how 1.d4 d5 2.Bf4 e6 is a London, not a Queen's Gambit Declined, even though Black's moves were the same. White's were not.
So yes, Identifying openings is more than just your own moves.
