1. Introduction to the variation 3... ♛h4+

  1. 1. e4
  2. 1... e5
    After 1... e5

    We play ♟f2-f4, transitioning to the starting position of the King's Gambit

  3. 2. f4
  4. 2... exf4
    After 2... exf4

    As with any gambit, the best response from the opponent is to accept the pawn sacrifice. White has two moves: ♞g1-f3 and the very tricky ♝f1-c4, which provokes Black into giving a check with ♛d8-h4. We develop the bishop!

  5. 3. Bc4
  6. After 3... Qh4+White to move.
    At the board3... Qh4+
    After 3... Qh4+

    A sensible response aiming to deprive White of the right to castle. We play ♚e1-f1 with a further attack by ♞g1-f3 on ♛h4

  7. 4. Kf1
    After 4. Kf1

    This is a blunder

  8. 4... Bc5
    After 4... Bc5

    At first glance, what seems like a logical move turns out to be a blunder. We play ♟d2-d4, seizing the center with tempo.

  9. 5. d4
  10. 5... Bb6
    After 5... Bb6

    Now is the perfect moment to continue development: we play ♞g1-f3, taking advantage of the awkward position of the enemy ♛

  11. 6. Nf3
  12. 6... Qe7
    After 6... Qe7

    Combining business with pleasure: we play ♞b1-c3 both to reinforce the ♟e4 pawn and to bring a new piece into play

  13. 7. Nc3
  14. After 7... Nf6White to move.
    At the board7... Nf6
    After 7... Nf6

    A logical attempt to complete development turns out to be a decisive mistake: we play ♟e4-e5, taking advantage of Black’s lack of central control and forcing the ♞f6 to a less favorable position.

  15. 8. e5
  16. 8... Ng4
    After 8... Ng4

    We capture ♝c1xf4, preventing the possible jump ♞g4-e3

  17. 9. Bxf4
  18. 9... O-O
    After 9... O-O

    White's position is absolutely winning. All that remains is to fully capitalize on the better placement of their pieces to achieve a decisive advantage. We play ♞c3-d5, bringing the piece into the attack!

  19. 10. Nd5
  20. 10... Qd8
    After 10... Qd8

    Which black piece is the most active? — ♞g4. We confidently play ♟h2-h3, forcing Black to send the ♞g4 to the edge of the board.

  21. 11. h3
  22. After 11... Nh6White to move.
    At the board11... Nh6
    After 11... Nh6

    Confidently capture with ♝ f4 - h6, ruffling the hairstyle of the enemy ♚

  23. 12. Bxh6
  24. 12... gxh6
    After 12... gxh6

    Only a small task remains: to reach the opponent’s ♚. We jump in with ♞d5-f6, planning to bring the ♛d1-d2 into play next!

  25. 13. Nf6+
  26. 13... Kh8
    After 13... Kh8

    We play ♛d1-d2, threatening checkmate in two moves. The rest is a matter of just a few moves.

  27. After 14. Qd2Black to move.
    At the board14. Qd2

2. Unfortunate development ♝f8-c5 #1

  1. 1. e4
  2. 1... e5
    After 1... e5

    We play ♟f2-f4, transitioning to the starting position of the King's Gambit

  3. 2. f4
  4. 2... exf4
    After 2... exf4

    As with any gambit, the best response from the opponent is to accept the pawn sacrifice. White has two moves: ♞g1-f3 and the very tricky ♝f1-c4, which provokes Black into giving a check with ♛d8-h4. Let's develop the bishop!

  5. 3. Bc4
  6. After 3... Qh4+White to move.
    At the board3... Qh4+
    After 3... Qh4+

    A sensible response aiming to deprive White of the right to castle. We play ♚e1-f1 followed by an attack with ♞g1-f3 on ♛h4.

  7. 4. Kf1
  8. 4... Bc5
    After 4... Bc5

    At first glance, what seems like a logical move turns out to be a blunder. We play ♟d2-d4, seizing the center with tempo.

  9. 5. d4
  10. 5... Bb6
    After 5... Bb6

    Now is the perfect time to continue development: play ♞g1-f3, taking advantage of the awkward position of the enemy ♛

  11. 6. Nf3
  12. 6... Qe7
    After 6... Qe7

    Combining the pleasant with the useful: we play ♞b1-c3 both to support ♟e4 and to bring a new piece into play

  13. 7. Nc3
  14. After 7... c6White to move.
    At the board7... c6
    After 7... c6

    A more successful attempt from Black, aiming to limit the mobility of ♞c3. Since we cannot deliver any threats for now, we capture the pawn — ♝c1xf4, bringing a piece into play.

  15. 8. Bxf4
  16. 8... Nf6
    After 8... Nf6

    As we already know from the first example, the absence of the black ♟d6 allows us to confidently play ♟e4-e5, completely seizing space in the center.

  17. 9. e5
  18. 9... Nh5
    After 9... Nh5

    If we have the opportunity to advance, we certainly do so by playing ♝f4-g5, forcing a weakness in Black's camp by provoking the move ♟f7-f6 forward.

  19. 10. Bg5
  20. 10... f6
    After 10... f6

    What should we do: exchange with ♟e5xf6 or maintain the pin by playing ♝g5-h4? If we choose ♟e5xf6, we allow the ♞h5 to escape its dubious position. Therefore, it’s better to retreat with ♝g5-h4, provoking Black into a mistake.

  21. 11. Bh4
  22. After 11... g5White to move.
    At the board11... g5
    After 11... g5

    Excellent, the mistake has been provoked! Black overlooked the dubious placement of ♞h5, naively assuming that we are forced to save ♝h4. We confidently strike with ♞f3xg5, opening up an attack on ♞h5!

  23. 12. Nxg5
  24. 12... fxg5
    After 12... fxg5

    With great pleasure, we capture the knight — ♛d1xh5!

  25. 13. Qxh5+
  26. 13... Kf8
    After 13... Kf8

    We play ♝h4xg5 with a quick checkmate to the opposing ♚f8 to follow.

  27. After 14. Bxg5Black to move.
    At the board14. Bxg5
