About the Scandinavian Defense
Black hits e4 immediately with 1...d5. After 2.exd5 Black takes back with the queen or the knight.
After 2...Qxd5 3.Nc3, the queen moves again, usually to a5 or d6.
Black develops with ...Nf6, ...c6, ...Bf5 and ...e6: a solid, easy setup.
White gains time by attacking the queen, so Black must not lose more tempi.
