Sicilian Defence, Smith–Morra Gambit
|Moves||1.e4 c5 2.d4 cxd4 3.c3|
|Named after||Kenneth Ray Smith
White sacrifices a pawn to develop quickly and create attacking chances. In exchange for the gambit pawn, White has a piece developed after 4.Nxc3 and a pawn in the center, while Black has nothing but an empty square at c7. The plan for White is straightforward and consists of placing his bishop on c4 to attack the f7-square, and controlling both the c- and d-files with rooks, taking advantage of the fact that Black can hardly find a suitable place to post his queen.

The Smith–Morra is named after two players, Pierre Morra from France (1900–69), and Kenneth Ray Smith of the Dallas Chess Club (1930–99). Hence in Europe the name Morra Gambit is preferred; names like Tartakower Gambit and Matulovic Gambit have disappeared.
Morra published a booklet and several articles about the Smith–Morra around 1950. Smith wrote a total of nine books and forty-nine articles about the gambit. When Smith participated in an international tournament against several top grandmasters in San Antonio in 1972, he essayed the Smith–Morra three times, against Donald Byrne, Larry Evans, and Henrique Mecking, but wound up losing all three games.
Black has a wide choice of reasonable defences after 1.e4 c5 2.d4 cxd4 3.c3. White sometimes plays 2.Nf3 and 3.c3, which depending on Black's response may rule out certain lines.
Morra Gambit Accepted: 3...dxc3 4.Nxc3
- Classical Mainline: 4...Nc6 5.Nf3 d6 6.Bc4 e6 7.0-0 Nf6 8.Qe2 Be7 9.Rd1 e5 10.h3 or 10.Be3
- Scheveningen setup: 4...Nc6 5.Nf3 d6 6.Bc4 e6 7.0-0 Nf6 (or Be7) 8.Qe2 a6 9.Rd1 Qc7 (probably inferior Qa5) 10.Bf4 (10.Bg5) Be7
- Siberian Variation: 4...Nc6 5.Nf3 e6 6.Bc4 Nf6 and 7...Qc7, with the idea being after 7.0-0 Qc7 8.Qe2 Ng4!, 9.h3?? loses to the famous "Siberian Trap" 9...Nd4!, winning the queen. If instead White plays 9.Rd1, preventing 9...Nd4, black can continue with 9...Bc5 with a clearly better game.
- Nge7 Variations: 4...Nc6 (or 4...e6) 5.Nf3 e6 6.Bc4 a6 (Nge7) 7.0-0 Nge7 (d6 8.Qe2 Nge7 9.Bg5 h6) 8.Bg5 f6 9.Be3
- 6...a6 Defence: 4...Nc6 5.Nf3 d6 6.Bc4 a6 eventually 7...Bg4
- Fianchetto: 4...g6 (4...Nc6 5.Nf3 g6 allows 6.h4!?) 5.Nf3 Bg7 6.Bc4 Nc6
- Chicago Defence: 4...e6 5.Bc4 a6 6.Nf3 b5 7.Bb3 d6 8.0-0 and Black plays ...Ra7 at some stage
- Early Queenside Fianchetto: 4...e6 5.Bc4 a6 6.Nf3 b5 7.Bb3 Bb7
Morra Gambit Accepted: 3...dxc3 4.Bc4 cxb2 5.Bxb2
This line is similar to the Danish Gambit.
Morra Gambit Declined
- Advance Variation: 3...d3
- First transposition to the Alapin: 3...Nf6 4.e5 Nd5
- Second transposition to the Alapin: 3...d5 4.exd5 Qxd5 (Nf6) 5.cxd4
The latter has a bad reputation, as square c3 is free for the knight. Still 5...Nf6 (5...e5; 5...Nc6 6.Nf3 e5) 6.Nf3 e6 7.Nc3 Qd6 is likely to transpose to a main line of the Alapin: 2.c3 d5 3.exd5 Qxd5 4.d4 e6 5.Nf3 Nf6 6.Bd3 Nc6 7.0-0 cxd4 8.cxd4 Be7 9.Nc3 Qd6.
- Another anti-Sicilian gambit is the Wing Gambit (1.e4 c5 2.b4).
