The Vienna Game is a chess opening characterised by the moves

1. e4 e5

2. Nc3

giving the position shown to the right.

White's second move is less common than 2.Nf3, which can lead to the Ruy Lopez, Giuoco Piano, Scotch Game and other openings. It is also of more recent vintage; a book reviewer wrote in the New York Times in 1888 that "since Morphy only one new opening has been introduced, the 'Vienna' ".^[1] The original idea behind 2.Nc3 was to play a type of delayed King's Gambit with an eventual f4, but in modern play White often plays more quietly, for example by fianchettoing his king bishop with g3 and Bg2. Black most often continues with 2...Nf6, but 2...Nc6 is also quite playable, as is the unusual 2...Bc5 3.Nf3 d6!

Weaver W. Adams, whom Grandmaster Larry Evans described as having an "all or nothing" mentality, famously claimed that the Vienna Game led to a forced win for White.^[2] However, Grandmaster Nick de Firmian, in the 15th edition of Modern Chess Openings (MCO-15), concludes that the opening leads to equality with best play by both sides.^[3]

[edit] 2...Nf6

White has three major options: 3.f4, 3.Bc4 and 3.g3. Also possible, but usually without independent significance, is 3.Nf3, when 3...Nc6 transposes to the Four Knights Game.

[edit] 3.f4

3.f4, the Vienna Gambit, is best met by 3...d5, striking back in the centre, since 3...exf4 4.e5 Qe7 5.Qe2 forces Black's knight to retreat. After 4.fxe5 Nxe4, 5.Qf3 is well met by 5....Nc6, with the point 6.Nxe4 Nd4. 5.d3 is also possible, but the normal continuation is 5.Nf3. White obtains open lines and attacking chances, but Black can usually hold the balance with correct play.

[edit] 3.Bc4

3.Bc4 leads to a position which can also be reached from the Bishop's Opening (1.e4 e5 2.Bc4). Black has several choices here; 3...Bc5 can transpose to the King's Gambit Declined after 4.d3 d6 5.f4 Nc6 6.Nf3; after 3...Nc6 4.d3, 4...Na5, 4...Bc5 or 4...d6 are all playable; 3...Bb4 4.f4 Nxe4 5.Qh5 0-0 leads to wild but probably equal play, according to de Firmian in MCO-15.^[4] Also possible is 3...Nxe4, when 4.Nxe4 d5, forking bishop and knight, is fine for Black.^[5] The attractive-looking 4.Bxf7+ is weak; after 4...Kxf7 5.Nxe4 d5! (inferior is 5...Nc6 6.Qf3+, when Black cannot play 6...Kg8?? because of 7.Ng5! 1-0 Davids-Diggle, London Banks League 1949, while 6...Ke8 leaves the king awkwardly placed in the center)^[6][7] 6.Qf3+ (6.Qh5+ g6 7.Qxe5? Bh6! wins for Black)^[8] Kg8 7.Ng5!? (hoping for 7...Qxg5?? 8.Qxd5+ and mate next move, Schottlaender-Ed. Lasker, simultaneous exhibition, Breslau c. 1902) Qd7!, with a large advantage for Black in view of his bishop pair and pawn center.^[9][10] After 3...Nxe4, White usually continues instead 4.Qh5 (threatening Qxf7#) 4...Nd6 5.Bb3 when Black can either go for the relatively quiet waters of 5...Be7 6.Nf3 Nc6 7.Nxe5 g6 8.Qe2 (or 8.Nxc6 dxc6 9.Qe5 0-0) Nd4 9.Qd3 Nxb3 10.axb3 Nf5 11.0-0 d6, which led to equality in Anand-Ivanchuk, Roquebrune 1992.^[11] or the complexities of 5...Nc6 6.Nb5 g6 7.Qf3 f5 8.Qd5 Qe7 9.Nxc7+ Kd8 10.Nxa8 b6, which the Irish correspondence chess player and theorist Tim Harding extravagantly dubbed "the Frankenstein-Dracula Variation."^[12]

[edit] 3.g3

3.g3 is a quiet continuation in which White fianchettoes his king's bishop, a line played by Vasily Smyslov on a few occasions, most notably in a win over Lev Polugaevsky in the 1961 USSR Championship. That game continued 3...d5 4.exd5 Nxd5 5.Bg2 Be6 6.Nf3 Nc6 7.O-O Be7 8.Re1 Bf6 9.Ne4 O-O 10.d3 Be7 11.a3 Nb6 12.b4, resulting in a position which the Encyclopaedia of Chess Openings assesses as slightly better for White. The main line today, however, is considered to be 5...Nxc3 6.bxc3 Bd6 7.Nf3 O-O 8.O-O. A major alternative for Black is 3...Bc5 (3...Nc6 normally transposes into one of the other lines).

[edit] 3.a3

In addition to these lines, the late American master Ariel Mengarini advocated the whimsical 3.a3, sometimes called Mengarini's Opening. It is not a serious try for advantage, but is essentially a useful waiting move that gives White an improved version of Black's position after 1.e4 e5 2.Nf3 Nc6. First, the "Reversed Ruy Lopez" with 3...Bb4 is ruled out. Second, after 3...d5, 4.exd5 Nxd5 5.Qh5!? gives White an improved version of the Steinitz Variation of the Scotch Game, since Black can never play ...Nb4, an important idea for White in the mirror-image position. Third, after 3...Bc5, 4.Nf3 gives a reversed Two Knights Defense. Then the typical 4...Ng4 may be met by 5.d4 exd4 6.Na4, when 6...Bb4+, White's usual move in the mirror-image position, is impossible. After 4...Ng4, White may also play improved versions of the Ulvestad Variation (6.b4 in the above line) and Fritz Variation (6.Nd5 c6 7.b4), since when White plays b4 his pawn is protected, unlike in the mirror-image position. If Black plays more quietly with 3...Bc5 4.Nf3 Nc6, then 5.Nxe5! Nxe5 6.d4 gives White some advantage. The best line for Black may be 3...Bc5 4.Nf3 d5 5.exd5 0-0 (better than 5...e4 6.d4, when the normal 6...Bb4 is impossible), and if 6.Nxe5, 6...Re8 7.d4 Bxd4! 8.Qxd4 Nc6, as in the mirror-image line. Also possible is 3...Bc5 4.Nf3 d6, when Black stands well after 5.Bc4 Be6, while 5.d4 cxd4 6.Nxd4 gives White little or no advantage.

[edit] 2...Nc6

White again has the possibility of 3.f4, with a type of King's Gambit, or 3.g3. Most often, White plays 3.Bc4, when the solid 3...Nf6 transposes to the 2...Nf6 3.Bc4 Nc6 line. Weaker is 3.Bc4 Bc5, when 4.Qg4! is awkward to meet. 4...Kf8 and 4...g6 are thought the best moves, but neither is too appealing for Black. The natural 4...Qf6?? loses to 5.Nd5! Qxf2+ 6.Kd1, when White's king is in no real danger, and White has multiple threats: 7.Qxg7; 7.Nxc7+; and 7.Rf1 Qd4 8.d3 threatening to trap Black's queen with 9.c3.^[13]

[edit] Hamppe-Muzio Gambit

The Hamppe-Muzio Gambit (or Vienna Hamppe-Muzio Gambit) is characterised by the moves

1.e4 e5

2.Nc3 Nc6

3.f4 exf4

4.Nf3 g5

5.Bc4 g4

6.0-0 gxf3

7.Qxf3

As with its close relative, the sharp Muzio Gambit, White sacrifices the knight on f3 in return for a powerful attack against the black king. It is named after Austrian theoretician Carl Hamppe and classified under ECO code C25.

The Dubois variation continues 7...Ne5 8.Qxf4 Qf6.

[edit] Steinitz Gambit

The Steinitz Gambit, 1.e4 e5 2.Nc3 Nc6 3.f4 exf4 4.d4, was a favorite of Wilhelm Steinitz, the first World Champion. White allows Black to misplace White's king with 4...Qh4+ 5.Ke2, hoping to prove that White's pawn center and the exposed position of Black's queen are more significant factors. Unlike Steinitz, who famously opined that, "The King is a fighting piece!", few modern players are willing to expose their king this way. The Steinitz Gambit is thus rarely seen today.

[edit] 2...Bc5

This is an offbeat but playable alternative, as played (for example) by former world champion Capablanca against Ilya Kan at Moscow 1936.^[14] Now 3.f4 d6 leads to the King's Gambit Declined.^[15] Weak is 3.Qg4 Nf6! 4.Qxg7 Rg8 5.Qh6 Bxf2+ when Black had a large advantage in Tsikhelashvili-Karpov, USSR 1968, since 6.Kxf2?? Ng4+ would win White's queen.^[15] Another offbeat possibility is 3.Na4, when 3...Bxf2+!? 4.Kxf2 Qh4+ 5.Ke3 Qf4+ 6.Kd3 d5 leads to wild complications, as in the famous game Hammpe-Meitner, Vienna 1872. However, the quiet 3...Be7 leaves Black with a good game.^[16]

Instead of these third moves, White usually continues with 3.Nf3, when 3...Nc6?! (transposing to the Three Knights Game) 4.Nxe5! Nxe5 5.d4 Bd6 6.dxe5 Bxe5 7.Bd3 leads to a large advantage for White.^[17] Stronger is 3...d6! Then 4.Na4 Nd7 5.d3 Ngf6 6.Be2 0-0 7.0-0 c6 8.Nxc5 Nxc5 9.Ne1 Ne6 10.c3 d5 is about even.^[15] The main line runs 4.d4 exd4 5.Nxd4 Nf6 6.Bg5 (6.Be2 d5 7.e5 Ne4 8.0-0 Nxc3 leads to equality^[15] h6 7.Bh4 0-0 8.Nb3 and now de Firmian in MCO-15 gives 8...Bb4 9.Bd3 Re8 10.0-0 Bxc3 11.bxc3 g5! 12.Bg3 Nxe4, when Black's "chances are at least equal".^[15]
