2. exd5
editAfter 2. exd5, Black can recapture the pawn.
2...Qxd5 retakes the pawn immediately. This is the mainline, also known as the Mieses-Kotrč variation. Black regains the pawn but allows White to develop with tempo against the queen: 3. Nc3 and the black queen must move again, usually to 3...Qa4. 3. Nf6 is also tried, with the idea of retaining the option of pushing both c4 and d4 and taking over the centre.
2...Nf6 is called the Modern Scandinavian. Black delays recovering the pawn. Now if 3. Nc3?! to defend d5, 3...Nxd5 4. Nxd5 Qxd5 and Black has nicely centralised queen with no danger of Nc3. The mainline is 3. d4, just giving back the pawn. 3. c4!? to hold onto the pawn transposes into a Caro-Kann Panov attack (3...c6 4. d4 cxd5 5. Nc3).
Gambits like 2...c6, the Blackburne-Kloosterboer gambit, or 2...e6 are inferior and don't give enough for the pawn.
