Restricted king's bishop's gambit: position after 3. Bf1 – e2

Template: checkerboard / maintenance / new

The restricted king's bishop's gambit is a rarely played variant of the accepted king's gambit , an opening in chess . Together with other variants of the King’s Runner's Gambit , it is classified under the ECO code C 33 .

The restricted king's bishop's gambit is created after 1. e2 – e4 e7 – e5 2. f2 – f4 e5xf4 by moving 3. Bf1 – e2 .

history

According to information in the Handbuch des Schachspiels , it was first analyzed by Carl Ferdinand Jänisch in 1843 , then by Max Lange in 1855 . In the master practice of the 19th century it was used by Henry Edward Bird , who won a game against Miksa Weiß with it in 1888 . The variant became known mainly because it was played in four games by Savielly Tartakower in the 1924 New York tournament. He won against Efim Bogoljubow and Frederick Dewhurst Yates , drew with Alexander Alekhine and lost to José Raúl Capablanca . In today's grandmaster practice, the variant no longer occurs.

Opening theory aspects

Alekhine described the idea of ​​the variant in the New York tournament book in 1924. In the case of the thematic black move g7 – g5, White can move his bishop to f3 and then develop the king knight to e2. In this way he avoids the knight being attacked by g5 – g4. Another advantage compared to the usual bishop development after c4 is that Black's counter-attack in the center with d7 – d5 does not increase the tempo. This can be seen, for example, after Black's natural development move 3.… Ng8 – f6, which can advantageously be followed by 4. e4 – e5. However, the move Be2 does not pose any direct threats and therefore, in Alekhin's view, cannot be dangerous for Black. Tartakower contradicted this in his book Die hypermoderne Schachpartie , in which he described Be2 as the "most lasting continuation of the King's Gambit". Modern theorists do not share this view, as Alexei Suetin calls the runner move “modest” and not in keeping with the spirit of the King's Gambit. Kurt Richter and Rudolf Teschner were of the opinion that 3. Be2 could not be good for reasons of principle because it would move the white queen.

There are several possible answers for black:

  • 3.… Nb8 – c6, played by Yates, is considered weak.
  • 3.… Ng8 – e7, played by Alekhine, leads to an equalization in his opinion.
  • 3.… f7 – f5 is an interesting counterattack that was already known in the 19th century. Black wants to open the f-file and after 4. e4xf5 Qd8 – h4 + 5. Ke1 – f1 use White's unrocheted king position.
  • 3.… d7 – d5, played by Capablanca, is generally considered the best answer. In the game of 1924 this was followed by 4. e4xd5 Ng8 – f6 5. c2 – c4 c7 – c6 6. d2 – d4 Bf8 – b4 + (Bogoljubow played weaker 6.… c6xd5, after which White after 7. Bc1xf4 d5xc4 8. Be2xc4 Bf8 – b4 + 9. Nb1 – c3 had a pretty good position) 7. Ke1 – f1 (on 7. Nb1 – c3 or Bc1 – d2 Black could answer 7.… Nf6 – e4)… c6xd5. In this position, according to Paul Keres , Black is better. The point of Black's game is that after 8. Bc1xf4 dxc4 9. Bf4xb8 (threatens to win pieces after 9.… Ra8xb8 10. Qd1 – a4 +) the strong intermediate move 9.… Nf6 – d5 follows. Instead, Tartakower suggested the moves 8. c4 – c5 or 9. Be2xc4 as possible improvements, but from today's point of view these are not very promising.
  • 3.… Qd8 – h4 +
