Key ideas for both sides

White

  • Play 4.dxe5 Nxe4 5.Qd5, hitting the knight and f7 at once, so Black must find ...Nc5.
  • After ...Nc5 use Bg5 to gain time and look for queen trades that leave Black with weak pawns.
  • 4.Nc3 Nbd7 leads to the Lion Variation, with h3, g4 and a4 as White's main plans.
  • Bc4 is the Klein Variation, aiming at f7 and inviting tactics.

Black

  • After 4.dxe5 take on e4 and answer 5.Qd5 with ...Nc5 to cover f7 and the knight.
  • Develop with ...Be6 and accept a queen trade on c5 if it leaves your structure healthy.
  • Against 4.Nc3, play ...Nbd7, ...Be7, ...c6 and ...O-O for the solid Lion setup.
  • Against 4.Bd3, take on d4 and fianchetto with ...g6 and ...Bg7.

Plans and pawn structure

The position depends on White's choice. After 4.dxe5 Nxe4 5.Qd5, the queens come off quickly and White has a small endgame edge thanks to the better pawn structure. After 4.Nc3, the center stays tense and White plays h3, g4 and a4 while Black keeps e5 with knights and the e7 bishop. After 4.Bd3, Black takes on d4 and plays a fianchetto with ...g6 and ...Bg7.
