Key ideas
- 2...Qxd5 3.Nc3 costs Black a tempo, but the queen usually retreats to a5 or d6 and the position stays solid.
- 2...Nf6 aims to regain the pawn later and keeps the queen at home.
Plans for White
Use the extra tempi from attacking the queen to build a lead in development.
Plans for Black
Develop smoothly with ...Nf6, ...Bf5 or ...Bg4, ...c6 and ...e6, reaching a Caro-Kann-like structure.
