Petrov Defense

13. Boden-Kieseritzky Gambit 3.Bc4 Nxe4 4.Nc3

A venomous gambit where White sacrifices pawns for a rapid attack: 3.Bc4 Nxe4 4.Nc3 Nxc3 5.dxc3. Black must avoid greed and play the cold, sturdy 5...f6! followed by Qe7, slamming the door on e5 and leaving White with zero compensation.

Move by move

  1. 1.e4 – White opens with the classical 1.e4, controlling d5 and f5 and freeing diagonals for both the f1 bishop and the queen to begin an open game.
  2. 1...e5 – You respond symmetrically with 1...e5: staking your claim in the center, preventing d4, and opening paths for your own pieces.
  3. 2.Nf3 – White develops the king's knight toward the center, attacking your e5 pawn and preparing rapid kingside castling in two moves.
  4. 2...Nf6 – The Petrov Defense! With 2...Nf6 you disregard White's attack on e5 and launch a symmetrical counterstrike against their e4 pawn.
  5. 3.Bc4 – The Bishop's Opening or Boden-Kieseritzky Gambit: White develops the bishop to c4 aiming straight at the vulnerable f7 square.
  6. 3...Nxe4 – You capture the undefended central pawn with 3...Nxe4: putting White's tactical ambition to the test with concrete, solid play.
  7. 4.Nc3 – White sacrifices a pawn with 4.Nc3, hoping to gain rapid piece development and open attacking files against your king in the center.
  8. 4...Nxc3 – You accept the trade with 4...Nxc3: removing White's active attacking knight and drastically diminishing their tactical potential.
  9. 5.dxc3 – White recaptures with the d-pawn, opening the file for their queen and clearing diagonals for both of their attacking bishops.
  10. 5...f6 – Masterly key move with 5...f6! Permanently locking down any knight jumps to g5 and sealing your central fortress flawlessly.
  11. 6.O-O – White completes kingside castling, hoping to organize an attack along the open files with queen and rooks against your king.
  12. 6...Qe7 – Solid defense with 6...Qe7: preparing queenside development with d6 and Be6 while preserving your clean extra pawn in safety.
