You probably forgot a black knight on c6. In the diagram white wins with 2.Bd4. Note also that white is a piece ahead.
Please read carefully what I wrote before you reply. My comment is clearly about the next white move (2.Bd4)
But it is black to move
What on Earth are you saying? Arisktotle's point is as clear as day. In your position, White can respond to 1...d5 with 2. Bd4. In the original game, a knight was on c6, making 2. Bd4 a losing move. Rather than repeating the same sentence a billion times, you can read through the comment carefully and understand the point.
