General remarks

The Evans Gambit is an aggressive variant of the Giuoco Piano

, which normally continues with the positional moves 4. c3 or 4. d3. The idea behind the move 4. b4 is to give up a pawn in order to secure a strong centre and bear down on Black's weak-point, f7. Ideas based on Ba3, preventing Black from castling
Castling
Castling is a special move in the game of chess involving the king and either of the original rooks of the same color. It is the only move in chess in which a player moves two pieces at the same time. Castling consists of moving the king two squares towards a rook on the player's first rank, then...

, the Evans poses a challenge for Black since the usual defenses (play ...d6 and/or give back the gambit pawn) are more difficult to pull off than with other gambits (Interestingly, Fine was beaten by this gambit in a friendly game against Bobby Fischer, in just 17 moves: Fischer-Fine 1963 1-0.)

The most obvious and most usual way for Black to meet the gambit is to accept it with 4... Bxb4, after which White plays 5. c3 and Black usually follows up with 5... Ba5 (5... Be7 and, less often 5... Bc5 and 5... Bd6, the Stone Ware Variation, are also played). White usually follows up with 6. d4. Emanuel Lasker

's line is 4... Bxb4 5. c3 Ba5 6. d4 d6 7.0-0 Bb6 8.dxe5 dxe5 9.Qxd8+ Nxd8 10.Nxe5 Be6. This variation takes the sting out of White's attack by returning the gambit pawn and exchanging queens, and according to Fine, the resulting simplified position "is psychologically depressing for the gambit player" whose intent is usually an aggressive attack. Chigorin did a lot of analysis on the alternative 9.Qb3 Qf6 10.Bg5 Qg6 11.Bd5 Nge7 12.Bxe7 Kxe7 13.Bxc6 Qxc6 14.Nxe5 Qe6, which avoids the exchange of queens, but reached no clear verdict. Instead White often avoids this line with 7.Qb3 Qd7 8.dxe5, when Black can return the pawn with 8...Bb6 or hold onto it with 8...dxe5, though White obtains sufficient compensation in this line.

Alternatively Black can meet 6.d4 with 6...exd4, when White can try 7.Qb3, a move often favoured by Nigel Short

. 7.0-0 is traditionally met by 7...Nge7 intending to meet 8.Ng5 or 8.cxd4 with 8...d5, returning the pawn in many lines, rather than the materalistic 7...dxc3 which is well met by 8.Qb3 with a very dangerous initiative for the sacrificed pawns. Alternatively 7...d6 8.cxd4 Bb6 is known as the Normal Position, in which Black is content to settle for a one-pawn advantage and White seeks compensation in the form of open lines and a strong centre.

Alternatively the gambit can be declined with 4... Bb6, when 5. a4 a6 is the normal continuation. But due to the loss of tempo involved, most commentators consider declining the Evans Gambit to be weaker than accepting it, then giving up the pawn at a later stage. Also, Black can play the rare Countergambit Variation (4... d5), but this is thought to be rather dubious.

Bishop retreats

After 4.b4 Bxb4 5.c3, the Bishop must move or be captured. The common retreats are listed here, with the good and bad sides of each:

5...Ba5

, this is Black's most popular retreat. It gets out of the way of White's central pawns, and pins the c3 pawn if White plays 6.d4, but it has the disadvantage of removing the a5 square for the black king's knight. Black usually subsequently retreats the bishop to b6 to facilitate ...Na5, which is particularly strong when White opts for the Bc4, Qb3 approach.

5...Bc5

, this is the second most popular retreat, with White scoring better than after 5...Ba5. This is often played by people unfamiliar with the Evans Gambit, but is arguably not as good as 5...Ba5, because 6.d4 attacks the bishop and narrows down Black's options as compared with 5...Ba5 6.d4.

5...Be7

This has often been considered one of the "safer" retreats, and has been played by Anand. After 6.d4 Na5, White can attempt to maintain an initiative with 7.Be2 as played by Kasparov, or immediately recapture the pawn with 7.Nxe5.

5...Bd6
