Bishop's Opening

When runner game is a chess opening, which is subdivided into several variants. The Bishop's is one of the open-ended games.

The runner game is a solid opening with some sharp variations. The disadvantage that white committing itself early with 2.Lf1 - c4 is compensated by the fact that White has some other development opportunities, such as white can be after 2 ... f6 - Ng8 decide between 3.d2 -d4 and 3.d2 -d3. Often, the white lady after e2 or a structure with c2 - c3, d2 -d3 and Nb1 -d2 develop. White has a choice of quieter or sharp variations.

The opening is under the ECO code C 23 - C 24 to find.

It provides transitions, eg by 3.Sg1 -f3 in the King Knight game or, for example in the Vienna Game by 3 Nb1 - c3. For the French chess master François -André Philidor Danican she was the best of all openings.

The opening is nowadays hardly played, so you can often surprise the enemy with variants such as 2 ... f6 3.d2 -d4 - Ng8.

The runner game begins with the trains 1.e2 -e4 e7 - e5 - c4 2.Lf1. The most played replies are second ... Ng8 - f6, 2 ... Bf8 - c5 and 2 ... Sb8 - c6.

From the Bishop's, the shepherd leads Matt, a common beginner's mistake: 1 e4 e5 2 Bc4 Bc5 (or Nc6 ) 3 DH5 Nf6 4 Dxf7 #

2 ... c7 - c6

Black plans so that the pawn d7 -d5. White can prevent this with 3 Dd1 - e2, develop aggressive game with 3.d2 -d4 or further develop normally and thus allow ... d7 -d5 3.

Variant: ( 1.e2 -e4 e7 - e5 - c4 c7 - c6 2.Lf1 ) 3.Dd1 - e2 In this case it is possible for the Black d-pawn with 3 ... d6 d7 only one field to push forward with other trains continue to develop solid or permit with 3 ... c5 Bf8 that White can try a combination.

3 ... c5 Bf8 4.Lc4xf7 ? Ke8xf7 5.De2 - c4 d7 -d5 6.Dc4xc5 d5xe4 7.Dc5xe5 Ng8 - f6 Now White has won a pawn, but to compensate Black receives strong initiative, so White must play very accurately now. In addition, the black e - pawn inhibits the white development. In the game Boharchirtuk - Fleischmann ( Regensburg, 1946) continued to follow 8.Sg1 - e2 - e8 Rf8 9.De5 -d4 Qd8 - c7 - c3 10.Sb1 Bc8 - f5 11.Se2 - g3 Bf5 g6 - 12.Dc4 - c5 Kf7 -f8 and White has survived the worst. Instead of 9 ... Qd8 - c7, would have been in place though probably Dd8xd5, with the variant 10.Se2xd4 Re8 -d8 11.Sd4 - e2 Sb8 - a6? threatens Sa6 b4 12.a2 -a3 unclear position, White is to compensate for the farmer profit in a significant development disadvantage.

Variation: 3.d2 -d4?

3 ... e5xd4? 4.Dd1xd4 The lady is difficult to sell due to the current feigned field c6.

3 ... Ng8 - f6 with probable Transfer to Ponziani Gambit (see 1.e2 e5 -e4 e7 - 2.Lf1 - c4 Ng8 - f6 3.d2 -d4 e5xd4 4.Sg1 -f3 c7 - c6)

3 ... d7 -d5 4.e4xd5 c6xd5 5.Lc4 - b5 Bc8 - d7 6.Lb5xd7 Sb8xd7 7.d4xe5 Sd7xe5 after a rather quiet game, with black, however, have to live with the shortcoming of the d- ISOLANI developed. It is possible: 8.Sg1 - e2? Ng8 - f6 9.0-0 Bf8 - d6 10.Sb1 - c3 Bd6 - c7 11.Lc1 - g5 - g4 12.h2 Ne5 - h3 h7 - h6 h4 g7- g5 - 13.Lg5 14.h3xg4 g5xh4 15.Se2 -d4 T8 - g8 16.f2 -f3 - e5 LC7 17.Tf1 - e1 - e7 Qd8 18.f3 - f4 ( computer game 386/33 Rex 2 30 - Super C, 1991) Black comes under the wheels.

An interesting constellation in which the two players received exactly the same position with inverted colors, resulted in correspondence chess game Hoffmann - Nolte 2004: 1.c2 - c3? e7 - e5 2.d2 -d4 e5xd4 3.c3xd4 Bf8 - b4 4.Lc1 -d2 d7 -d5 Lb4xd2 5.Sb1xd2 6.e2 -e4

Variant: 3.Sg1 -f3 White d7 -d5 may also admit consciously to abzutauschen and find its strengths in character development. eg: 3 ... d7 -d5 4.e4xd5 c6xd5 5.Lc4 - b5 Bc8 - d7 6.Dd1 - e2 balanced position

2 ... g7- g6? the Königsfianchetto here is suboptimal: ( Fuellgrabe - Amiri Babaei, Berlin, 1996) 3.Sb1 - c3 Bf8 - g7 4.d2 -d3 Ng8 - f6 5.f2 - f4 Sb8 - c6 -f3 d7 - d6 6.Sg1 7.0 0 Bc8 - g4 - h3 8.h2 Lg4xf3 9.Dd1xf3 Nc6 -d4? 10.Df3 - c7 - c6 f2 11.f4xe5 d6xe5 12.Lc1 - g5 Qd8 - b6 13Lg5xf6 1-0

2 ... Sb8 - c6

This response often provides transitions into other openings: 3.Sg1 -f3 leads to the King Knight game 3.Sb1 - c3 leads in the Vienna Game, after 3.d2 -d3 Ng8 - f6 the game is also often in other openings: 4. Nb1 - c3 goes white to the Vienna Game, with 4.Sg1 -f3 in the Two Knights in Nachzuge. An exception, however, the variation 3.f2 - f4?

Variant: 3.f2 - f4

This pawn is very similar to the King's Gambit. White has good chances to get enough compensation for the pawn and space advantage.

3 ... e5xf4 4.Sg1 -f3 g7- g5 - g7 5.0-0 Bf8

(another possibility would be for Black 5 ... g5 - g4 6.Sf3 - e1 Bf8 - c5 7.Kg1 -h1 but after 7 ... Nc6 - a5? 8.Lc4xf7 ! Ke8xf7 9.Tf1xf4 Kf7 - e8 10.Dd1xg4 Qd8 - e7 11.Dg4 - h5 ( Morch - Hansen, Copenhagen, 1954) White got an irresistible attack).

6.d2 d6 d7 -d4 7.c2 - c3 h7 - h6 gives the Hanstein variant of the King Knight Gambit.

2 ... Ng8 - f6 ( Berlin Defence )

In addition to variants, which can lead to related openings such as the Two Knights in Nachzuge by 3.Sg1 -f3 Sb8 - c6 or by 3.Sb1 - c3 to Vienna Game and his Frankenstein - Dracula variation, there is still a very interesting, completely different continued: 3.d2 -d4. The Urusov Gambit or in the English language Ponziani 's Gambit called.

The Adopted Urusov Gambit with

3 d2 -d4 e5xd4 4 Sg1 -f3 Sf6xe4 5 Dd1xd4

And his three main variants - corresponding to the fifth part of Black - allows white despite loss of a central pawn a pace and be able to achieve space savings. Good interaction between the characters and the best possible use of their firepower give a slight advantage for white in logical sequel.

Try this Black play through 4 ... Sb8 - c6 to avoid it lands in the variation 4.d4 ed4 of Two Knights in Nachzuge.
