Answers.Text: @B.Swan, I think there are some differences that make 1.c4 d5 more favorable for white then 1.e4 d5. 1. White still has two center pawns, so they can get stronger control of the center. 2. In 1.e4 d5, even though the knight jumps to c3 with tempo, it blocks the c-pawn, which makes it a little bit harder for white to coordinate, in 1.c4 d5, the c-pawn is already traded, so it is not an issue.

  Against `1.c4`. This will allow white to exchange their c-pawn for black d-pawn and later gain a tempo. `2. cxd5 Qxd5 3.Nc3`, or `2...Nf6` at some point will be followed with `e4` with tempo. All in all, white can take control of the center.
  
  According to [lichess'](https://lichess.org/) database `1.c4 d5` is very rarely played.
  
  However, the move is probably not losing; stockfish gives it: 0.6. The significance of this advantage varies a lot depending on the player's strength.
