Key ideas for both sides

White

  • 3.Nxe5 wins a clean pawn; after ...Nc6, trade on c6 and develop with Nc3 and g3.
  • Keep pieces safe after the capture. Watch for ...Qe7 or ...Qa5 tricks against the knight.
  • If you do not want to take, Bc4 and c3 with d4 also give a good game.

Black

  • After Nxe5, ...Nc6 at least develops with tempo and forces a trade on c6.
  • Follow with ...Nf6 and ...d5 to fight the center and use open lines.
  • Look for active piece play to make up for the lost pawn.
  • Next time keep e5 covered with ...d6 or ...Nc6 on move two instead.

Plans and pawn structure

After 3.Nxe5, White is a pawn up with a healthy position. White develops with Nc3, g3 and Bg2, castles and slowly converts. Black has a half-open b-file and a lead in development after ...Nc6, ...Nf6 and ...d5. These give some play, but the extra pawn is solid. If White does not take the pawn, Black gets a closed center with ...Nc6 and ...d6 and a normal game.

How to play against it

With White, take on e5 at once. Follow with Nxc6 if Black plays ...Nc6, then develop with Nc3 and g3. Do not waste time or chase pieces with the queen. The extra pawn is healthy and wins in the long run if you castle and trade pieces.
