Evans-Gambit

When Evans Gambit or Captain Evans Gambit is an opening of the chess game, which is divided into several variants. The Evans Gambit is one of the open-ended games.

Each of its main variants begin with the following moves: 1.e2 -e4 e7 - e5 -f3 2.Sg1 Sb8 - c6 - c4 3.Lf1 Bf8 - c5 4.b2 - b4

The Evans Gambit develops from the Italian game. A famous example is the so-called Evergreen game between Adolf Anderssen and Jean Dufresne.

Background and idea of ​​Gambit

This opening is named after its inventor, the ship Captain William Davies Evans. He applied for the first time in 1824 at a game between the ports of Milford and Dunmore.

Should the black players accept the gambit, so gets some white lead in development and for the time being a so-called full center because he can still make another after d4 by the time gain to the farmer on e4. An example of this the following variant:

1.e2 -e4 e7 - e5 -f3 2.Sg1 Sb8 - c6 - c4 3.Lf1 Bf8 - c5 4.b2 - b4 - c3 Lc5xb4 5.c2 Bb4 - a5 6.d2 -d4 d7 - d6

Another possibility is a rejection of Gambit by the train 4 ... LB6, after which the white player wins space on the queenside.

Practice at grandmaster level

Although the rejection of the gambits last brought good results for black at the level of the Grand Master, the pawn sacrifice is usually assumed. The results here are very different, but generally, these variants are considered sufficient for black.

It is noteworthy that both Bobby Fischer and Garry Kasparov, otherwise both staunch supporters of the Ruy Lopez with white, this Gambit inserting deemed playable and in the course of her career a few times. As Kasparov in 1995 for the first time then almost completely disappeared from the tournament practice opening successfully used against Viswanathan Anand, there was a resurgence of the Evans Gambit. Since it is rare, but later on at regular intervals in the grandmaster practice. A large contribution to the ongoing maintenance at this level has mainly the British grandmaster Nigel Short, who continues to find new and improved features in lesser known play Gambit.

Typical opening error

A common mistake is the assumption of further " sacrificed " farmers on c3 after 4 ... Bc5 5.c3 Lxb4? 6.d4 exd4 7.0-0 dxc3? After 8.Lxf7 Kxf7 9.Dd5 White wins back the rotor and is connected to lead in development in the face of open black 's king position much better.

First short game

The following game was played between 1826 and 1827 Captain Evans and Alexander McDonnell in London. It is the original version, the diverter from 5.b2 - b4 on the fourth train took place only at a later time. 4.0-0 d6 d7 - 5.b2 - b4 - c3 Lc5xb4 6.c2 Bb4 - a5 7.d2 -d4 Bc8 - g4 8.Dd1 -b3 Qd8 - d7 ( 8 ... Lg4xf3 was even stronger! . ) 9.Sf3 - g5 (Better was 9.Lc4xf7 ! Dd7xf7 10.Db3xb7! Ta8 - b8 11.Db7xc6 ±) Nc6 -d8 10.d4xe5 d6xe5 11.Lc1 -a3 Ng8 - h6 12.f2 -f3 La5 - b6 13.Kg1 -h1 Bg4 - h5 14.Tf1 -d1! Qd7 - c8 15.Td1xd8 ? Do not use with this train his advantage and allows Black to free himself from his predicament. Bringing victory here was the train 15.Db3 - b5 ! , Because black thereafter can no longer defend itself against the attack of white. There follows either 15 ... SD8- c6 -d5 16.Lc4! Dc8 - d7 17.Ld5xc6! b7xc6 18.Db5xe5 Ke8 -d8 19.De5 - e7 ! Kd8 - c8 20.Td1xd7 - or 15 ... c7 - c6 16.Db5xe5 ! SD8- e6 17.Sg5xe6 f7xe6 18.Lc4xe6! Dc8 - c7 - d7 19.Le6 and Matt in the next train. 15 ... Dc8xd8 16.Sg5xf7 Qd8 - h4? This unmotivated and senseless trip the lady still allows White to win after he awarded the first chance. This would be after 16 ... Qd8 - f6! 17.Sf7xh8 0-0-0! = The position offset and have been a draw for black problem. 17.Db3 - b5 c7 - c6 18.Db5xe5 Ke8 - d7 - e6 19.De5 Kd7 - c7 - d6 20.La3 #

Second short game

This game was played in 1862 between Wilhelm Steinitz and Pilhal in Vienna. Particular attention should be paid to three times pawn, which White sent the castling of black and inhibits its mating attack thus makes it all possible. 4 ... Lc5xb4 5.c2 - c3 Bb4 - a5 6.0-0 f6 7.d2 -d4 - Ng8 The second pawn sacrifice. 7 ... e5xd4 8.Lc1 -a3 - d6 d7 9.e4 e5 - The third pawn. (But was also 9.c3xd4! Sf6xe4 10.d4 -d5 Nc6 - e7 11 Dd1 -a4 c7 - c6 12.d5xc6 0-0 13 Bc4 a6 = a good continuation. ) 9 ... d6xe5 10.Dd1 -b3 Qd8 - d7 11.Tf1 - e1 Qd7 - f5? ( A much stronger defense here was 11 ... e5 -e4! ) 12.Lc4 - b5! Nf6 - d7? ( Here promised 12 ... Bc8 - e6! Charged with assault on white lady at the most, but possessed White even better position. ) 13.Db3 -d5 La5 - b6? A useless train, initiates his defeat with the black. Right here would be 13 ... Qf5 - e6! been with forciertem exchange of queens. 14.Sf3xe5! Nc6 - e7? This facilitates Black his opponent the winning plan, but the better defenses would have been the loss of the lady consequence. 15.Se5xd7! Df5xd5? Although the defeat was not anyway to avert, there were a number of serious defenses. After this robbery Ladies Black is now dull. 16.Sd7 - f6 ! Ke8 -d8 17.La3xe7 #

Third short game

In this third example game that was played in 1942 in New York between Helms and Tenner, Black dispensed with the beating of the farmers on b4 and 4 ... Bc5 - b6 5.a2 -a4 - a7 a6? This may not stop the black pawn storm. Was significantly better 5 ... Sc6xb4 here! 6.a4 a5 7.b4 LB6 - a7 - b5 a6xb5 8.Lc4xb5 Ng8 - f6 9.Lc1 -a3? Not a good continuation. Although delayed castling white from black, but obtained no benefit is seen. Rather, he gives his opponent a pawn to own without adequate compensation for it. In addition, there was by the ideal 9.Lb5xc6! also more suitable development features, such as the short castling or Lc1 -b2. 9 ... Sf6xe4 This Pawn does not pose any risk for black. 10.Dd1 - e2 Se4xf2? The idea is to capture the rook on h1. However, the Springer sprayed on f2 no acute threat, why this train was a crucial mistake. Since his king is still uncertain, Black could not think of material gain here. Correct the beating with the rotor, because this gives the white king chess. By train the white king Black gained the extra pace that he needs in his own defense: 10 ... La7xf2 ! 11.Ke1 -f1 - f7 f5! 12.c2 - c3 ( necessary to avoid Nc6 -d4, as this train would cement the advantage of Black) Ta8xa5 13.d2 -d3 Ta5xb5 14.d3xe4 Tb5xb1 15 Ta1xb1 Lf2 - a7 16.e4xf5 Qd8 - f6 17 kf1 - e1 Df6xe5 ∓ [ The attempt to defend the pawn on f5, everything would make it worse: 17.g2 - g4? h7 - h5! 18.Sf3 -d2 d7 -d5 b5 19.Tb1 h5xg4 20.Tb5xd5 Df6xf5 21.Kf1 g2 and Black has an even greater positional advantage. ] With correct play Black gained so for a tower a runner and three extra pawn and the better position and would have a good chance of winning. But since he has beaten the farmers f2 with the wrong figure, he gets instead at a disadvantage. 11.Sf3xe5! This very strong clearance is only possible because the black knight is no longer in the e-file! The scope of the error in the tenth train is obviously now. 11 ... Nc6 -d4? Black seems to have still not noticed that he is close to Matt. Once again it is fixed solely on profit figure and therefore not relevant to the lady, which allows a two brisk Matt White. Here, nothing was lost, 11 ... Nc6 - e7! would eliminate the risk and introduced a completely balanced game. 12.Se5xd7 ! Sd4xe2 13.Sd7 - f6 #
