The runner game is an opening of the chess game , which is divided into several variants. The runner game is one of the open games .
The bishop game begins with moves 1. e2 – e4 e7 – e5 2. Bf1 – c4 . The most common responses are 2.… Ng8 – f6 , 2.… Bf8 – c5 , and 2.… Nb8 – c6 .
The bishop game is a solid opening with some sharp variations. The disadvantage that White fixes himself early with 2. Bf1 – c4 is compensated for by the fact that White has some other development possibilities, e.g. B. After 2.… Ng8 – f6 White can decide between 3. d2 – d4 and 3. d2 – d3. White can often develop the queen after e2 or a setup with c2 – c3, d2 – d3 and Nb1 – d2. White has the choice between quieter or sharp variants. It offers transitions, e.g. B. by 3. Ng1 – f3 in the Königsspringer game or z. B. in the Viennese game with 3. Nb1 – c3. For the French chess master François-André Danican Philidor , it was the best of all openings. The runner game is rarely played these days.
The opening can be found under the ECO codes C23 – C24.
Schäfermatt , a common beginner's mistake, is derived from the bishop's game : 1. e4 e5 2. Bc4 Nc6 3. Qh5 Nf6 4. Qxf7 #
variants
2.… Nb8 – c6
This reply often offers transitions into other openings: 3. Ng1 – f3 leads to the Königsspringer game , 3. Nb1 – c3 leads to the Viennese game .
After 3. d2 – d3 Ng8 – f6 White moves on to the Viennese game with 4. Nb1 – c3 , followed by the double knight with 4. Ng1 – f3 . Variation 3. f2 – f4 is an exception . This pawn sacrifice leads into the King's Gambit . White has a good chance of getting enough compensation and space advantage for the pawn .
3.… e5xf4 4. Ng1 – f3 g7 – g5 5. 0–0 Bf8 – g7
(Another possibility for Black would be 5.… g5 – g4 6. Nf3 – e1 Bf8 – c5 + 7. Kg1 – h1 Qd8 – g5 . After 7.… Nc6 – a5? 8. Bc4xf7 +! Ke8xf7 9. Rf1xf4 + Kf7 – e8 10 Qd1xg4 Qd8 – e7 11. Qg4 – h5 +, however, White got an irresistible attack in Morch - Hansen, Copenhagen 1954.)
6. d2 – d4 d7 – d6 7. c2 – c3 h7 – h6 results in the Hanstein variant of the King's Jumper Gambit .
2.… Ng8 – f6 (Berlin Defense)
In addition to variants that lead to related openings such as the two-knight game followed by 3. Ng1 – f3 Nb8 – c6 (3.… Nf6xe4 is the Boden-Kieseritzky Gambit of the Russian Defense ) or through 3. Nb1 – c3 to the Viennese game and its Frankenstein -Dracula variant , there are other continuations: the passive 3rd d2 – d3 which allows c7 – c6 4. Ng1 – f3 d7 – d5; 3. d2 – d4, the Urusov gambit, (called Ponziani's gambit in English-speaking countries); 3. f2 – f4 (called Greco Gambit in the English-speaking world), which receives the reply 3.… Nf6xe4 4. d2 – d3 Ne4 – d6.
The accepted Urusov gambit with 3. d2 – d4 e5xd4 4. Ng1 – f3 Nf6xe4 5. Qd1xd4 including its three main variations - corresponding to Black's fifth move - enables White to gain a tempo and space despite losing a center pawn . A good interplay of the pieces and the best possible use of their firepower result in a slight advantage for White if continued consistently.
If Black tries to avoid this line with 4.… Nb8 – c6 , he ends up in the variant 4. d2 – d4 e5xd4 of the double knight game .
2.… c7 – c6
Black is planning the pawn move d7 – d5 with it. White can prevent this with 3. Qd1 – e2 , develop aggressive play with 3. d2 – d4 or develop it normally and thus allow 3.… d7 – d5 .
-
3. Qd1 – e2 In this case it is possible for Black to move the d-pawn only one square forward with 3.… d7 – d6 , to develop solidly with other moves or to allow it with 3.… Bf8 – c5 , that white can try a combination .
- 3.… Bf8 – c5 4. Bc4xf7 + !? Ke8xf7 5. De2 – c4 + d7 – d5 6. Qc4xc5 d5xe4 7. Qc5xe5 Ng8 – f6 (diagram). Now White has won a pawn, but Black receives strong initiative to equalize , so White now has to play very carefully. In addition, the black e-pawn inhibits white development. The game Boharchirtuk - Fleischmann (Regensburg, 1946) was followed by 8. Ng1 – e2 Rf8 – e8 9. De5 – d4 Qd8 – c7 10. Nb1 – c3 Bc8 – f5 11. Ne2 – g3 Bf5 – g6 12. Qc4 – c5 + Kf7 – f8 and White survived the worst. Instead of 9.… Qd8 – c7 , however Qd8xd4 would have been appropriate, with the variant 10. Ne2xd4 Re8 – d8 11. Nd4 – e2 Nb8 – a6 !? threatens Sa6 – b4 12. a2 – a3 unclear position, White is at a clear development disadvantage to compensate for the pawn gain.

Position after 7.… Ng8 – f6
-
3. d2 – d4 !?
- 3.… e5xd4 ?! 4. Qd1xd4 The queen can only be driven away with difficulty because of the currently adjusted c6 square.
- 3.… d7 – d5 4. e4xd5 c6xd5 5. Bc4 – b5 + Bc8 – d7 6. Bb5xd7 + Nb8xd7 7. d4xe5 Nd7xe5 then a rather calm game develops, although Black has to live with the deficit of d- Isolani . It is possible: 8. Ng1 – e2 !? Ng8 – f6 9. 0–0 Bf8 – d6 10. Nb1 – c3 Bd6 – c7 11. Bc1 – g5 Ne5 – g4 12. h2 – h3 h7 – h6 13. Bg5 – h4 g7 – g5 14. h3xg4 g5xh4 15. Ne2 –D4 Rh8 – g8 16. f2 – f3 Bc7 – e5 17. Rf1 – e1 Qd8 – e7 18. f3 – f4 (Computer game 386/33 Rex 2 30 - Super C , 1991) Black gets under the wheels.
- 3. Ng1 – f3 White can also consciously allow d7 – d5 in order to swap and seek his strengths in the development of pieces. E.g .: 3.… d7 – d5 4. e4xd5 c6xd5 5. Bc4 – b5 + Lc8 – d7 6. Qd1 – e2 with an even position
Other replies
- 2.… Bf8 – c5 offers a transition into Italian : 3. Ng1 – f3 Nb8 – c6 .
3. Qd1 – h5 threatens the Schäfermatt.
- 2.… f5 ?! Which, after Gioacchino Greco named "Calabrian counter Gambit ", is considered risky and double-edged continuation because White 4 by 3. Lc4xg8 Th8xg8 Dd1-h5 + g7-g6 5. Dh5xh7 Rg8-g7 6. Qh7-h8 the destruction of the black kingside succeed .
- 2.… b7 – b5 ?! is a pawn sacrifice that doesn't help Black any further: 3. Bc4xb5 c7 – c6 4. Bb5 – e2 d7 – d5 5. e4xd5 c6xd5 6. d2 – d4
