Key ideas for both sides

White

  • Take with 3.dxe5, the top engine move, and meet ...Nd7 with Bg5 and Nc3.
  • After ...dxe5, trading queens on d8 and taking e5 with the knight wins a pawn.
  • Keep the extra pawn safe with quick development, Nc3 and short castling.

Black

  • After 3.dxe5, play ...Nd7 to defend e5, then ...f6 to win back the pawn.
  • Avoid ...dxe5, which loses a pawn after the queen trade and Nxe5.
  • Develop quickly with ...Be7 and ...Ngf6 to make up for the lost pawn.

Plans and pawn structure

The Vos Gambit is a dubious gambit: White takes with 3.dxe5 and keeps a big edge. Black tries ...Nd7 and ...f6, but White's development with Bg5 and Nc3 is faster. After ...f6 and exf6, Black regains the pawn but leaves e6 weak and the e-file open. White develops with Nc3 and castles, aiming rooks at the e-file and Black's loose king. Black must find active moves to justify the pawn.

How to play against it

As White, take with 3.dxe5 and develop with Bg5 and Nc3. Don't let Black win back the pawn for free. If Black plays ...dxe5, trade queens and take on e5 with the knight. Keep your pieces active and castle short before Black's ...f6 break.
