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.

Midwest Class this weekend in Wheeling

Don't miss this Illinois Tour event!  Details on the ICA website.  The prize fund is guaranteed to be $16,000, and if the 250 paid entry quota is hit, the prize fund will be $20,000. Not bad for a weekend event!

I won't be there to play (I make my living as a tax accountant, and the procrastinator's deadline is October 15th), but hope to stop by on Sunday to kibitz and see friends.

Out of the frying pan . . .

In the following game, my 12.Ng5! made it surprisingly hard for my opponent to defend his f-pawn. He did find a way, it's true - but it allowed me to pull off Boden's Mate. Instead of the ugly 13.b3, why didn't I play 13.Be2! with the same idea? You got me.

When the pin doesn't pin

In the following game, Black forgets that a pin against the queen is only a relative pin. Thus, unlike an absolute pin (a pin against the king), the pinned player can ignore the pin if it is advantageous to do so. Compare the Légal Trap and Imbaud-Strumilo, corr. 1922.

Quads

Published USCF Regular Rating (or tournament director's estimate, if the player is not USCF-rated) determines player seeding. Players will be grouped into 4-player quads starting with the top-seeded player. If the bottom group has between 5 and 7 players, the bottom group will be paired as a Swiss section. No byes. Please come planning to play three rounds.

Three rounds. Digital clocks are required and will be set to G/26 plus 3 seconds delay. Some club clocks are available for use by players who do not own clocks. Sets are supplied.

Schedule: Registration from 9:00 to 9:30 am. Registration/sign-in for pre-registered players will close and quads will be formed at 9:30 a.m. sharp. First Round 9:45 am, rest of rounds ASAP (estimated ending time 12:30 p.m.).
No byes, no lunch break. Out of consideration for your quad-mates, please plan on playing all three rounds.

Mate me, maybe


So Carly Rae Jepsen is around musicians all day long and can't find chess competition?  She needs to hang out with better musicians: Philidor and Ray Charles are dead, but Flea, Sting, Bono, and RZA come to mind. As the previous examples suggest, having a talent and an ego big enough to assume one's name seems to help: Madonna has been known to push wood.

Both music and chess produce prodigies. Hmm.

I'll Take You There: Illinois Class Championships at Concordia University

Concordia University's Koehneke Community Center
Last year's Illinois Class Championships were held at the Orland Park Cultural Center, an attractive location with a lot of pluses. But for me, at least, it had one severe drawback: I couldn't get there except by bumming a ride. The nearest transit access was a Metra station a mile away, on a route that doesn't serve Orland Park on Saturdays until 1:30 in the afternoon and has no service at all on Sundays.

Life can be tough for the car-free chess player in Chicago; suburban organizers often don't take us into account. At all. So when I was asked to take over the organization of this year's Illinois Class Championships, I decided to make it a priority to find a location that would be easily reachable by transit-dependent city dwellers as well as suburban and downstate motorists. I found that location in River Forest's Concordia University. Just outside the city, it's close enough to make a transit commute feasible, yet it also offers free garage parking.

Despite its streetcar-suburb location, Concordia is still a hike from the nearest 'L' or Metra station. So I'm conducting an experiment: From 9 to 9:50 AM on Saturday and Sunday, Nov. 17 and 18, Illinois Class players and their guests will be able to hop a free shuttle van from the Harlem Green Line station in Oak Park, which sits adjacent to the Oak Park Metra station, to the Concordia campus. The van will leave the train station every 10 minutes. If you're a transit-dependent city resident, like me, I hope this will give you one more reason to attend the Illinois Chess Association's "other championship," which also happens to be the final event in this year's Illinois Chess Tour. (If your pride prevents you from accepting a handout -- or if you find yourself running late -- you can still get to Concordia from the Harlem 'L'/Oak Park Metra station via the 307 Harlem Pace bus.)

Another difference this year is that the event has been moved back to the weekend before Thanksgiving, to coincide with the ICA's annual meeting. The meeting will take place at the event site on Saturday, Nov. 17, at 1:30 PM. It's an open meeting, and ICA members are encouraged to attend. In place of the traditional banquet, there will be a catered luncheon buffet, with service starting at 1. Place your order in advance, and we guarantee there'll be food left for you even if your round 1 game runs long.

As for the main event, the Master/Expert section offers $1,000 in guaranteed place prizes, plus $100 prizes for the top players rated under 2200 and under 2100. Early entry (before Nov. 3) is $50, and FIDE-titled players with Illinois residency who register early play free. (ICA membership is required for this state championship event.) NTD Wayne Clark will be the ringmaster, with help from the Evanston Chess Club's Maret Thorpe and the St. Charles Chess Club's Gary Janssen.

And for players just starting out in tournament chess, we're offering a side event that, in my opinion, this area doesn't see enough of: a rated beginners' open. This G/30 Swiss is open to players without ratings or with ratings under 1200; the one-day, five-round schedule is designed to move you as efficiently as possible toward ditching that provisional rating. Early entry for the RBO is just $25 before Nov. 3.

Visit www.illinoisclass.com to read all the details, and get your registration squared away: after Nov. 3, the entry fee goes up to $60 ($30 for the RBO), and it's $70 ($35 for the RBO) if you register onsite.

Jeremy Silman profile on chess.com


Here's a funny profile of the former Games Editor of the Illinois Chess Bulletin (thirty years or so seems like only yesterday).

A trap in the Rubinstein French

The Rubinstein French (1.e4 e6 2.d4 d5 3.Nc3 (or 3.Nd2) dxe4) is a solid if somewhat passive line for Black. White is theoretically better because of his spatial advantage, but in practice this is not always so easy to prove. In my mind the following trap in the Rubinstein will always be associated with NM (and ICCM) Steve Tennant, who I saw pull it off in a tournament game about 35 years ago.

Unlike some other traps, such as the optically similar Caro-Kann trap 1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nd7 5.Qe2?! (hoping for 5...Ngf6?? 6.Nd6#!), 6.Qe2 against the Rubinstein is a good move even if Black avoids the trap. White gets his queen off the back rank and prepares a future O-O-O. The move has been played by the likes of world #1 Magnus Carlsen (in the game below) and World Champion Viswanathan Anand. After the natural 6...Nxe4 7.Bxe4(!) Nf6?, White wins a pawn with 8.Bxb7! Bxb7 9.Qb5+. The databases show that the trap is very successful: in 365chess.com's database, the position after 7.Bxe4 was seen exactly 100 times. Black fell into the trap with 7...Nf6? 60% of the time! I was astonished to see that victims included chess legends GM Ratmir Kholmov and former Women's World Champion Nona Gaprindashvili!

A great game to lose

IM Angelo Young grinds nine-year-old FM Awonder Liang in a bishop ending. Better to get painful losses out of the way early!

Student Overtakes Coach

Cross posted at Prospect Chess.

I knew it would happen eventually and this weekend Robert Moskwa upped his rating to 2017 to overtake my 2011 by going 5-1 at the North Shore Chess Center G60 tournament including a final round win over 2086 rated 7th grader Alex Bian.  The turning point came in the following position.


Playing the White pieces, Alex made the perfectly understandable decision to give his king a little breathing room with 22.h3?!  Unfortunately, this gave Black the opportunity to take the intiative with 22...Rf2 whereupon White allowed Black to activate his bishop with tempo by 23.Qd3? Bf5.  Ten moves later, White found himself in the following untenable position.


Technically material is even, but Black's active pieces and connected passed pawns give him an overwhelming position.  The funny thing about bishops of opposite colors is that they are extremely drawish when there are no other pieces on the board, but when you add rooks, they can become a huge advantage for the player with the initiative, almost as if he was playing with an extra piece since he can attack on squares that his opponent cannot adequately defend.

The Poisoned b-pawn

Tarrasch wrote in his famous treatise The Game of Chess, "It is very dangerous to make a raid with the queen early on in the game. In particular, the capture of the queen's knight's pawn with the queen often brings its own revenge." Irving Chernev facetiously observed in his 1000 Best Short Games of Chess, "Alvin Cass used to say, “My grandmother, when she was a little girl, told me never to capture the queen knight pawn with my queen.'" The miniature Botvinnik-Spielmann, Moscow 1935 is one famous debacle by a great player who disregarded Cass's granny's advice.

Modern theory is less dogmatic, as evidenced by the popularity of the so-called Poisoned Pawn Variation in the Najdorf Sicilian (1.e4 c5 2.Nf2 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 e6 7.f4 Qb6, intending 8.Qd2 Qxb2, a favorite of Bobby Fischer, and later played by the likes of Kasparov, Anand, and even Karpov. According to Larry Evans in New Ideas in Chess, James Sherwin, in capturing Bisguier's b-pawn in Bisguier-Sherwin, New York 1955, observed, "Why should I labor under antediluvian prejudices?" He won in 58 moves.

All of that said, one should not chase after the b-pawn without careful consideration. My opponent in this game joined the millions of players who've done so and later regretted it.

A note on the opening: 3...Qd6 in the Center Counter or Scandinavian Defense is a popular line these days. My 6.Ne5 was nothing special, and is usually met by 6...Nc6. After that, 7.Bf4!? Nxd4 (inferior is 7...Qxd4?! 8.Nxc6, especially if followed up with 8...Qxf4?? 9.Qd8# Mataoussi-Al Khelaifi, Women's Olympiad 2008) 8.Ng6!? Qe6+ 9.Ne5 Qb6 10.Nc4 Qe6+ 11.Ne5 Qd6 12.Ng6 Qe6+ 13.Ne5 led to an amusing draw by repetition in Smith-Serpek, New Zealand Championship 2000.

"Teacher overslept!" answers, part 1


I'm glad the strike ended relatively quickly: otherwise, I'd have been posting delinquent answers well into 2013.  These examples were lifted from Irving Chernev and ChessBase 2012.

Experienced players often resign against masters when they've lost a minor piece.  Beginners should keep playing until they understand why the position is hopelessly lost.

Youth vs. Experience

IM Angelo Young won the Young Masters vs. Experienced Masters, a Scheveningen System event held at the North Shore Chess Center on Sept. 15-16, with an impressive 3 1/2-1/2 score. NM Sam Schamkel was the top scorer among the youngsters, scoring 2-2.

 I'll be posting several games from this match after I work through the backlog of interesting games from the Illinois Open.

In the meantime, crosstable here (broken link fixed).

First game won for the franchise

Chopper Trading lost its first match to Rogue Squadron in the Chicago Industrial Chess League 4½-1½, but Reza Gholidzadeh had the honor of the team's first individual win...against yours truly.

The Hobbit, or There and Back Again

David Franklin annotates a game from the first round of the CICL season. With the center locked, the White king wanders out of the shire and wanders back with a win in its pocketses.

Steinitz was famous for king walks under fire, but Petrosian lifted the idea of the prophlyactic king walk (evacuating His Majesty from the kingside prior to a kingside break) from Nimzowitsch.
