The Sicilian busted?

About 30 years ago, FM Albert Chow told me that the Sicilian Defense was unsound, and that it was a matter of time before it was refuted. I laughed. He insisted that he was serious: while White's 1.e4 is an eminently logical move, 1...c5 was a silly move that does nothing for Black's development. Chow said that I had contributed to the ultimate refutation of the Sicilian with my win over David Sprenkle. I shook my head in disbelief. How could the venerable Sicilian, beloved by great players by Fischer and Kasparov, ever be busted?

Marc Esserman's book Mayhem in the Morra! features a newspaper headline on its cover: "Sicilian Refuted! Morphy and the Romantics Run Wild!" While I'm sure Esserman would admit that this is hyperbole intended to be funny and sell more books, he makes a much stronger case for the Smith-Morra Gambit than I could have imagined. As the following game illustrates, declining the gambit with 3...Nf6 (transposing to the Alapin Sicilian) is not a panacea. Was Albert right?
Black's resignation was premature, particularly given that this was a blitz game. The variation given at the end is Houdini 3's analysis of what might have happened.

The Deadly Isolani

Positions where White has an isolated pawn on d4 (IQP) arise in many openings, including the Queen's Gambit Accepted; Nimzo-Indian; Caro-Kann Defense, Panov-Botvinnik Variation; and Alapin Sicilian. In the game below, the IQP occurred in a Smith-Morra Gambit Declined, which transposed into an Alapin Sicilian. If Black wants to decline the Smith-Morra Gambit, 3...d5 is not the most effective way to do so; Black ends up in an Alapin Sicilian where he has exchanged on d4 prematurely. I recommend either accepting the gambit or playing 3...Nf6.

A lot of players are leery of taking on an IQP, fearing that it will be weak in an ending. However, as Tarrasch said, "Before the endgame, the gods have placed the middlegame." He also said, "He who fears an isolated queen's pawn should give up chess." The IQP supports a knight outpost on e5 and often results in a king-side attack for White.

Another advantage of the IQP is that a sudden liquidation of the center with d5 is sometimes dangerous for Black, as seen in the game below. Although Black's opening moves were very plausible, 12.d5! already left him tactically busted in view of his loose pieces on c6 and b4, and the unfortunate vis-à-vis of Black's queen and White's rook on the d-file. Houdini 3 gives Black's best line as 12...Na5 13.dxe6 (unleashing a discovered attack on the queen) Qe7 14.exf7+ Kh8. After 12...exd5 13.Nxd5 Nxd5 14.Bxd5, White threatened both 15.Bxc6 and 15.Bxf7+, winning Black's queen. Black tried to defend everything with 14...Qc7, but I unleashed a whirlwind attack on his king with 15.Qe4! Bb7 16.Ng5! g6 17.Qh4!, forcing the ugly 17...h5. Houdini says that I should have continued with 18.Qe4! (threatening Qxg6+) Kh8 (even worse is 18...Kg7 19.Bxf7! Rxf7? 20.Ne6+, winning the queen) 19.Bf4! (not 19.Bxc6? Qxc6! 20.Qxb4?? Qxg2#) Qe7 20.Bxc6, winning a piece. My 18.Bf4?! was less accurate, when Black could have played on with 18...Qe7. After 18...Bd6??, Black resigned before I could play 19.Bxd6 Qxd6 20.Bxf7+! Rxf7 21.Rxd6.

More Morra Mayhem

Marc Esserman has demonstrated both in his book Mayhem in the Morra! and in tournament practice that piece sacrifices on d5 can be very strong in the Smith-Morra Gambit (1.e4 c5 2.d4 cxd4 3.c3). In both Esserman-Van Wely, 2011 and Esserman-Sarkar, 2008 he successfully sacrificed a knight on d5, annihilating a GM and an IM in 26 and 16 moves, respectively. In the following game I tried to "be like Marc," but maybe my 10.Nd5!? was premature. The silicon monster thinks that Black is better if he declines the knight with 10...Na5! My opponent made the mistake of accepting it instead and was swiftly dispatched.

A trap in the Smith-Morra

Probably the best-known trap in the Smith-Morra Gambit occurs after 3...dxc3 4.Nxc3 Nc6 5.Nf3 d6 6.Bc4 Nf6?! 7.e5! (see diagram). After accepting the pawn Black has played three eminently reasonable-looking developing moves, but is suddenly in trouble! In the game below, he actually stumbles into checkmate - after trading queens, no less. In the final position, Black resigns in light of 10...Ke8 11.Nc7#! Marc Esserman writes, "I've lost count how many times I have delivered this comedic finish." (Mayhem in the Morra!, p. 205)

This trap isn't actually as fearsome as its reputation. After 7.e5!, Black certainly must avoid (a) 7...Nxe5?? 8.Nxe5 dxe5? 9.Bxf7+! Kxf7 10.Qxd8. Esserman considers his best line to be (b) 7...Ng4! 8.exd6 exd6! 9.O-O Be7 10.h3 Nge5 11.Nxe5 dxe5 12.Qh5 O-O 13.Rd1 Qa5 14.Be3, when "White's full range of motion more than compensates for Black's extra e5-pawn." Unfortunately the attractive 8.e6!? has, he says, been refuted by Rybka: 8...fxe6! 9.Ng5 Nge5 10.Nxe6 Qa5! 11.Bb3 Bxe6 12.Bxe6 Qa6! with a small advantage to Black. After (c) 7...dxe5 8.Qxd8+, Esserman says that Black's best is the surprising (c1) 8...Kxd8! 9.Ng5 Na5! when the obvious 10.Nxf7+? Ke8 11.Nxh8 Nxc4 will leave Black up material after he wins the beast on h8. Instead, he recommends 10.Bb5! Be6! 11.Nxe6+ fxe6, when Black is two pawns up but White is slightly better in light of his bishop pair, lead in development, and Black's tripled e-pawns. After the game continuation (c2) 8...Nxd8? 9.Nb5!, Black's best is 9...Rb8! (instead of 9...Kd7??) 10.Nxe5 (threatening Nc7#!) e6 11.Bf4! (Rybka) Nh5 12.Be3 Bb4+ 13.Kf1 O-O 14.Be2 a6 15.a3 Be7 16.Na7! Nf6 17.Rc1 Bd7 18.Nxd7 Nxd7 19.Rc7 Nf6 20.Nc8! and White wins. For more details, see pages 204-07 and 219-21 of Mayhem in the Morra!

Typical Smith-Morra craziness

Black's 5...Bg4!? is an unusual move not mentioned in the Smith-Morra Bible (Marc Esserman's Mayhem in the Morra!). It may be a decent move, possibly transposing to the important line 4...d6 5.Nf3 Nc6 6.Bc4 a6! 7.O-O Nf6 8.Qe2 Bg4!, which has scored extremely well for Black. If 5...Bg4!? is any good, 5.Bc4 (rather than my 5.Nf3) might be a more accurate move order. The game later descended into typical Smith-Morra mayhem. Yes, Virginia, 20.Bd5+ was more accurate than the needless piece sacrifice 20.Bb5+?

Back to Siberia

Many players, faced with the Smith-Morra Gambit (1.e4 c5 2.d4 cxd4 3.c3), try for a quick win with the Siberian Trap. A successful example of the trap is seen in the below game. After 9.h3?? Nd4! White gets mated after 10.Nxd4? Qh2# or 10.Qd3? Nxf3+ 11.Qxf3 Qh2#, or loses the queen for two knights after 10.hxg4 Nxe2+ 11.Bxe2.



Sicilian players like me love to ridicule the Smith-Morra. When IM Mario Campos-Lopez played the French Defense against Ken Smith at San Antonio 1972, Bent Larsen gave 1...e6 a question mark, noting that 1...c5 wins a pawn against Smith. Smith played his beloved gambit thrice in that tournament, losing to GMs Larry Evans and Henrique Mecking, and IM Donald Byrne.

However, IM Marc Esserman in his brilliant and entertaining new book Mayhem in the Morra! makes a strong case that the gambit is sound! He also plays it himself with great results, including a crushing win against GM Loek Van Wely.

Against the Siberian Trap, he extensively analyzes 8.Nb5! (improving on 8.Qe2?!) Qb8 9.e5! After 9...Nxe5?!, he analyzes 10.Nxe5 Qxe5 11.Re1! to a forced win for White. One line is 11...Qb8 12.Qd4! d6 13.Bf4! e5 14.Rxe5+! dxe5 (14...Be7 15.Rxe7+!; 14...Be6 15.Bxe6! dxe5 16.Bxe5 Qd8 17.Nc7+) 15.Bxe5 and Black's queen is trapped. After the alternative 9...Ng4 10.Bf4 a6 (he also analyzes 10...Ngxe5? 11.Nxe5 Nxe5 12.Bxe6! dxe6 (12...fxe6 13.Qh5+) 13.Rc1!) 11.Nd6+ Bxd6 12.exd6 b5 13.Bd5!! is Esserman's TN, which he analyzes as leading to at least a large advantage for White. The main line is acceptance of the sacrifice with 13...exd5 14.Re1+, which Esserman analyzes to a forced win.

I played 13.Bd5!! in two blitz games today, but both of my opponents declined the bishop. One game went 13...Bb7 14.Bxc6! Bxc6 15.Nd4! (another line given by Esserman), when Black could already resign in light of 15...Nf6 16.Nxc6 dxc6? 17.d7+ winning the queen. Here is the other game. Note that 15...Qb6!, leaving Black "only" a piece down, would have been a slight improvement.

In case you haven't gotten the idea, I highly recommend Esserman's book for anyone who plays 1.e4 as White or the Sicilian as Black, or just wants to play over some great tactical games.

Board 4: Eric Rosen crushes the Smith-Morra Gambit

If you play the Black side of the Sicilian, you need to have something prepared against the Smith-Morra.  In this game, we get a glimpse of Eric's preparation. 

But I suspect that White's move order was suboptimal: why not play 7.O-O and see how Black chooses to develop?  7.Bf4 is unnecessarily committal.

It's nice to get the first point on the board!
