Starting position of the Allgaier gambit after 5. Nf3 – g5

Template: checkerboard-small / maintenance / new

  • 4. h2-h4 . After 4. h4 the advance 4.… g5 – g4 is forced. After 4.… h6? would 5. hxg5 hxg5 6. Rxh8 win the rook and after 4.… f6? wins 5.Nxg5! (e.g. 5.… fxg5 6. Qh5 + Ke7 7. Qxg5 + Nf6 8. e5 wins the knight back, 7.… Ke8 8. Qh5 + along with Qe5 + even brings quality gain )
    • Allgaier Gambit : 5. Nf3 – g5. After 5.… h7 – h6 the piece sacrifice 6. Ng5xf7 is forced and leads to an attack.
    • Kieseritzky gambit (named after Lionel Kieseritzky ): 5. Nf3 – e5 . That is considered more sustainable. Continuing the Kieseritzky gambit with 5.… Ng8 – f6 6. Bf1 – c4 d7 – d5 (6.… Qd8 – e7 !?) 7. e4xd5 Bf8 – d6 8. 0–0 Bd6xe5, the result is the Rice gambit . It is named after the American entrepreneur Isaac Rice , who paid top players to study this variant and offered cash prizes in themed tournaments. Nowadays it is no longer played in tournament practice because it is incorrect.

In Boris Spasski - Bobby Fischer , Mar del Plata 1960, it happened 5.… Ng8 – f6 6. d2 – d4 d7 – d6 7. Ne5 – d3 Nf6xe4 8. Bc1xf4 Bf8 – g7. Then 9. c2 – c3 is a suggestion from Fischer.

  • 4. Bf1-c4
    • 4.… g5 – g4. White can save the knight with 5. Nf3 – e5 and switch to the attack on f7, or he sacrifices him, which means that he retains the initiative:
      • Salvio gambit : 5. Nf3 – e5 White brings the knight into the attack on the weak point f7, but risks… Qd8 – h4 +. The ECO code is C37.
      • Lolli-Gambit 5. Bc4xf7 + avoids black queen's chess on h4 because of Ke8xf7 6. Nf3xe5 +
      • Muzio Gambit : 5. 0–0 g4xf3 6. Qd1xf3 with unclear play
      • McDonnell gambit: 5. Nb1 – c3 g4xf3 6. Qd1xf3, is considered weaker than the Muzio gambit.
      • Ghulam-Kassim Gambit 5. d2 – d4
    • 4.… Bf8 – g7
      • Philidor variant (also called Philidor gambit): After 4.… Bf8 – g7 White tries to break the black pawn chain with 5. h2 – h4 . The answer h7 – h6 covers. Also Greco is associated with the explosion h4.
      • Hanstein variant (also called Hanstein Gambit): 4.… Bf8 – g7 5. d2 – d4 d7 – d6 6. 0–0 Nb8 – c6 7. c2 – c3 h7 – h6 (the variant is also possible through various changes of move can be achieved, e.g. by Fischer's sequence of moves, starting with 3.… d7 – d6; see below) 8. Qd1 – a4 Bc8 – d7 9. Q4 – b3 brings about the double threat Qb3xb7 and Bc4xf7 +. But 9.… Nc6 – a5 10. Bc4xf7 + Ke8 – e7 10. Qb3 – a3 Ke7xf7 12. Qa3xa5 Kf7 – g6 is even. An alternative to this is a setup with 8. g2 – g3 g5 – g4 9. Nf3 – h4.
      • The modern 4.… Bf8 – g7 5. g2 – g3 g5 – g4 6. Nf3 – h4 f4 – f3 7. d2 – d4 Nb8 – c6 8. Bc1 – e3 enables the free stroke 8.… d7 – d5 9. Bc4xd5 Ng8 -E7. 8.… d7 – d6 9. Nb1 – c3 Ng8 – f6 10. Qd1 – d2 Bc8 – e6 11. Bf1 – d3 Nc6 – b4 shows a different game against the bishop who developed early after c4. The modern 5. g2 – g3 is therefore used after Rosentreter's 4. d2 – d4 Bf8 – g7 or Quaades 4. Nb1 – c3 Bf8 – g7 to bring about long castling with Be3 and Qd2 .
  • Rosentreter Gambit 4. d2 – d4 with ideas like the Quaade Gambit, whereby according to EA Schmidt in the continuation 4.… g5 – g4 5. Nf3 – e5 Qd8 – h4 + 6. g2 – g3 f4xg3 7. Qd1xg4 Black through 7 .… Qh4xg4 8. Ne5xg4 d7 – d5 9. Ng4 – e3 d5xe4 10. h2xg3 Nb8 – c6 gets a good position. Shaw points out 10. Ne3 – d5 Bf8 – d6 11. Nb1 – c3. The caveman attack 5. Bc1xf4 g4xf3 6. Qd1xf3 therefore finds supporters and was already played by Morosewitsch . After 6.… Nb8 – c6, 7. c2 – c3 can comfortably cover d4. 4.… d7 – d6 leads to the Fischer defense .
  • Quaade-Gambit 4. Nb1 – c3 with the idea 4.… g5 – g4 5. Nf3 – e5 Qd8 – h4 + 6. g2 – g3 f4xg3 7. Qd1xg4. Now after 7.… g3 – g2 + 8. Qg4xh4 g2xh1D 9. Qh4 – h5 Ng8 – h6 10. d2 – d4, White gets a decisive attack, because Nc3 protects e4. Therefore it is better with 7.… Qh4xg4 8. Ne5xg4 d7 – d5 9. Bf1 – h3 d5xe4 10. Ng4 – f6 + Ke8 – d8 11. Bh3xc8 Kd8xc8 12. Nf6xe4 g3xh2 13. Rh1xh2 and equalization continued (analysis by EA Schmidt).

Other sequels

  • Cunningham gambit : 3.… Bf8 – e7 4. Bf1 – c4 Be7 – h4 +, the theory suggests 4.… Ng8 – f6.
  • Schallopp defense : 3.… Ng8 – f6, whereupon 4. e4 – e5 Nf6 – h5 is usually played
  • Modern defense: 3.… d7 – d5 4. e4xd5 Ng8 – f6. A spectacular example game is Spasski - Bronstein, USSR Championship 1960 .
  • Tolusch defense: 3.… Ng8 – e7
  • Becker Defense or Nordic Defense: 3.… h7 – h6 Bobby Fischer gave 4. d4 g5 5. h4 Bg7 6. g3 g4 7. Nh2 fxg3 8. Nxg4 (8. Qxg4 loses because of gh2 9. Qxg7 Qxh4 + 10. Kd1 Qf6 ) d5 9. e5 Bf5 10. Bf4 with compensation.
  • Fischer defense : 3.… d7 – d6. After a defeat against Boris Spassky in Mar del Plata published in 1960 Bobby Fischer at the American Chess Quarterly 1961 the famous article A bust to the king's gambit in which it 3. ... d7-d6 recommends "high-class waiting move" and "refutation" of King Jumper Gambits. The purpose of this move is to reach the Hanstein variant (see above) via 4. Bf1 – c4 without giving the opponent the opportunity to play the Kieseritzky gambit.
