Chess Opening Theory/1. e4/1...d5/2. exd5

= Scandinavian Defence: 2.exd5 = Black has the ability to immediately take back the pawn with /2...Qxd5/ but at the cost of a slower development, because White can win a tempo with 3. Nc3.

The other option is to play /2...Nf6/ attacking the pawn. White may try to keep the pawn (with 3. c4 or 3. Bb5+) or leave it and keep the initiative. As White has doubled pawns on the d file, the second option is probably the best.

Gambits like 2...c6 and 2...e6 are inferior and don't give enough for the pawn.
