TNM Round 7

Gaffagan Sits Alone At Top Of Championship Section With Two Rounds Remaining, Alexander Perlov Pulls To Within A Point of Jonah Busch In A/B, Venugopal Mani In Control Of U/1600.

In one of the more competetive championship section TNM's, Steve Gaffagan continues his strong play to remain the sole leader with 5.5/7 after securing a hard fought draw against one of the pre-tournament favorites, NM Eric Li. There was a glitch on the DGT for that game, which was unfortunate because it was an exciting game in which it appeared Gaffagan had a strong attack and needed great defensive technique from Eric to hold the draw. We will publish the correct full game in next week's newsletter from the scoresheet. This result keeps Eric in contention with 5/7, tying him for second place with WFM Natalya Tsodikova, who defeated NM Russell Wong. It will be a very exciting final two rounds!

Steve Gaffagan (red) drew NM Eric Li, and WFM Natalya Tsodikova took advantage of a tactical shot opportunity to score a big win against NM Russell Wong

In the A/B section, Jonah Busch (6.5/7) had a half point bye, so Alexander Perlov and Gagik Babayan were playing to try to move a half point closer to him. The result was a win for Perlov, who now sits in sole second place with 5.5/7, a full point behind. It seems Busch and Perlov will face off against each other next week with lots on the line, and it should be an exciting game. Many tough opponents are at 5/7, including Sergey Khristoforov, Ashik Uzzaman, Guy Argo, and Gagik Babayan. If Perlov can score a win against Busch, the door will be open for anyone to take first place in the section. 

Alexander Perlov (left) on board 9 moved to clear second in the A/B section while Venugopal Mani (right) defeated Mateo Hansen on board 10

In the U/1600 section, Venugopal Mani continued his dominance in the section with a win against Mateo Hansen. He now has 6.5/7, the only half point being the result of a half point bye. He is a half point ahead of Illia Gimelfarb, who already has lost to Mani. A whopping six players sit at 5/7, including Mateo Hansen, Albert Starr, Jerry Simpkins, Jon Cendejas, Eitan Neygut, and Valerie Jade. Will Mani pull completely away from the field? Or will one of these contenders take him down and open up the race in the final round? Tune in next week to find out!

Interview with FM James Eade

By FM Paul Whitehead

I don’t believe I had ever met James “Jim” Eade before quite recently – his tenure as Mechanics’ Institute Chess Club Director from 1996 to 1998 coincided with the time of my leaving for Virginia for 15 years.  I missed a lot, chess-wise, in the San Francisco Bay Area during that time.

I originally planned this article as a straight interview, and I asked Jim a few softballs, like:

Q.  How old are you and where are you from?

A.  I was born in 1957.  New Haven, Connecticut.


Q.  What’s your favorite food?

A.  Candied ginger

I don’t know if Jim likes softball, but I do know he loves baseball.

The author of Remember the MacCutcheon, as well as bestsellers Chess for Dummies and Chess Openings for Dummies – books I certainly need to look at if I want to bring my game back up to speed - Jim is also the author of (the amazingly titled) Chess Player’s Bible.

On Jim’s resume -

Past editor of the California Chess Journal.  Served on the executive Board of the USCF.  Past President of Cal Chess.  Past President of the Chess Journalists of America.  American Zone President of FIDE, 2000 – 2002.  Past trustee of the U.S. Chess Trust.

Q.  Proudest achievement in chess?

A.  Organizing the 1995 Pan-Pacific GM Invitational in San Francisco.

(I’m not exactly sure if this was the question… or the answer to the question! But it’s close.  And it allows me to add the tournament book, won by GM Victor Korchnoi and with annotations by GM Nick de Firmian, to the list of books Jim has written.)

There’s more here on Jim’s Wikipedia page:

Besides being a World of Chess Knowledge unto himself and an accomplished FIDE Master, Jim is a friend and fellow traveler with many in the Chess World: the great and the unknown.

I’ve really enjoyed hanging out with Jim while doing commentary on the TNM -  it’s been 3 times now, and I’m looking forward to more.   He takes the pressure off me, and gently points out my mistakes.  We make plans for the future, and talk about the old times as though we’d known each other for years.

I asked Jim what he’s up to now:

Q.  What are you up to now?

A.  I am Chairman and CEO of

The Eade Foundation’s goals, as Jim explains, is “Building communities through chess for those who cannot otherwise easily access the chess community”.  I urge you to take a look at Jim’s work, as chess is being increasingly seen as a way to help empower people, to help bring community.

I think Jim likes hanging out at the Chess Club because he feels that kind of community here.  I know that I feel it all the more strongly when Jim’s in the room.

Finally, there’s Jim the chess player.  Here’s a few games that he’s found memorable.  I’ll try to remember what he said about them, and to give a smart preamble to each.

(1) Eade,Jim (2240) - De Firmian,Nick E (2560) [A47]
Labor Day Festival op California, 1993

It's not every day you get to play a strong Grandmaster, let alone draw with one. Jim shows great fighting spirit, matching Nick move-for-move. In the final position Black might be better, but John Grefe's declaration that "black is winning" seems far-fetched. Nick has the strong players uncanny sense of danger - there's danger for black here too, despite the possibility of making a passed pawn on the kings-side. 1.d4 Nf6 2.Nf3 e6 3.Bf4 b6 4.e3 Bb7 5.Bd3 Be7


6.h3 c5 7.0-0 Nc6 8.c3 0-0 9.Nbd2 cxd4 10.exd4 a6


11.Qe2 b5 12.a4 b4 13.c4 d6 14.Rfe1 Re8 15.Bh2 Bf8


16.Rad1 g6 17.Nf1 Qa5 18.Qd2 Rad8 19.b3 e5 20.d5 Nb8


21.Bc2 Nbd7 22.g4 Nc5 23.Bg3 Bg7 24.Bh4 Rf8 25.Bg5 Rde8


26.Ng3 Kh8 27.Nh4 Bc8 28.Bh6 Bxh6 29.Qxh6 Ng8 30.Qd2 Qd8


31.Ng2 a5 32.f4 exf4 33.Qxf4 Qf6 34.Rf1 Qxf4 35.Rxf4 Kg7


36.Kf2 Nf6 37.Re1 Rxe1 38.Nxe1 Re8 39.Nf3 h6 40.Nd2 Bd7


41.Rd4 Re5 42.Nf3 Re7 43.Nd2 Bc8 44.Bd1 Re8 45.Bc2 Kf8


46.Rf4 Ke7 47.Nge4 Nfxe4+ 48.Bxe4 Rh8 49.Kg3 Rf8 50.Bc2 f5


51.Rf3 Kf6 52.Re3 Bd7 53.Nf3 fxg4




(2) Lobo,Richard (2270) - Eade,James V [E06]
Labor Day Festival op California, 1993

A really nice take-down of one of San Francisco's top Senior Masters. Despite the early exchange of queens white comes under a crushing attack. 14...Ng4! signals the end, and 21...Be3! is just the showy icing on the proverbial cake. 1.c4 e6 2.Nc3 d5 3.d4 Be7 4.Nf3 Nf6 5.g3 0-0


6.Bg2 dxc4 7.Ne5 c5 8.dxc5 Qxd1+ 9.Kxd1 Bxc5 10.f4 Nbd7


11.Nxc4 Rb8 12.e4 b5 13.Na5 Ba6 14.a3 Ng4 15.Kc2 Nf2


16.Re1 b4 17.axb4 Nd3 18.Rd1 Nxb4+ 19.Kb1 Bd3+ 20.Rxd3 Nxd3


21.e5 Be3 22.Kc2 Ne1+




(3) Eade,Jim (2335) - Au,Leslie [E72]
Hawaii op Hawaii, 1994

This is from another tournament organized by Jim, a futurity in Hawaii. This is a nice, powerful positional win over one of Hawaii's best. In the final position the bishop on c8 is lost. 1.d4 Nf6 2.g3 g6 3.Bg2 Bg7 4.e4 d6 5.Ne2 c6


6.0-0 Nbd7 7.c4 0-0 8.Nbc3 Qc7 9.h3 e5 10.Be3 b5


11.dxe5 dxe5 12.cxb5 cxb5 13.Nxb5 Qb8 14.a4 a6 15.Nd6 Qxb2


16.Qd3 Qb4 17.Rfb1 Qa5 18.Qc4 Qd8 19.a5 Ne8 20.Rd1 Nxd6


21.Rxd6 Qe7 22.Rc6 Bb7 23.Rc7 Rac8 24.Rb1 Rxc7 25.Qxc7 Bc8


26.Nc3 Re8 27.Nd5 Qa3 28.Nb6 Qxa5 29.Qc6 Qa2 30.Rc1




(4) Eade,Jim (2320) - Frias Pablaza,Victor J (2485) [A47]
USA-chT Amateur East Parsippany (1), 13.02.1999

Jim includes this game, saying IM Frias was the strongest player he beat, even though he was worse at one point. It's true: 17.cxd5?! was a positional mistake, and black was marginally better. However 20...Bxe5 gave up much: white straightened out his pawns, and black's feints on the kingside were nothing. A tactical oversight: 25...Qf5?? was brutally refuted. In the final position if 27...Ne7 28.Rxf8+ Kxf8 29.Ba3 Qg5 is met by Qc8 mate! 1.d4 Nf6 2.Nf3 c5 3.e3 b6 4.Bd3 Bb7 5.Nbd2 e6


6.0-0 Be7 7.b3 0-0 8.Bb2 cxd4 9.exd4 d6 10.Re1 a6


11.c4 Nbd7 12.h3 Re8 13.Re3 Bf8 14.Ne4 Nxe4 15.Bxe4 Bxe4


16.Rxe4 d5 17.cxd5 Nf6 18.Re2 Nxd5 19.Rc1 Bd6 20.Ne5 Bxe5


21.dxe5 Qg5 22.Re4 Rac8 23.Rec4 Rxc4 24.Rxc4 b5 25.Qc1 Qf5??

Kenn Fong on Guthrie "Mac" McClain

Below is an email sent to us by Kenn Fong on Guthrie "Mac" McClain, published with his permission. We thought it would be fitting given the McClain Memorial coming this weekend

William Guthrie "Mac" McClain (1910-1991)
"Mac" [nobody called him anything else] was a master chess player in the age when very few could make a living at chess. Instead he turned his analytical mind to business. His California Municipal Statistics" was the foremost bond rating company in California. 
Instead of making a living FROM chess, he made it possible for chess to thrive in Northern California. Besides George Koltanowski, Mac was probably the greatest benefactor of chess in this area. Although he did not trumpet his largesse, we have him to thank for many great events in the Bay Area, including two US Junior Championships; the most notable of which was Bobby Fischer's 1957 Triumph.
[After that tournament, Mac lent his car to some of the players to drive to the U.S. Open in Cleveland. Driving through some long stretches of desert, the players tried to teach Bobby how to drive. At some point, the car broke down with some simple malfunction and Mac laughed that the boys were swindled by a small town repair shop and had to call him to wire $200 to replace a fan belt.]
He published The California Chess Reporter for decades out of his office at 244 Kearney Street. (I have no doubt he chose the location because it was minutes away from the Mechanics.)
Mac was famous for concocting work for chessplayers who were broke. If one were to drive by his home on a summer afternoon, one might see a chessmaster mowing his lawn or painting his garage. It didn't matter if the chessmaster knew how to mow the lawn; what mattered was the chessmaster needed twenty bucks.
Mac was not only a supporter of chess; he was a strong competitor. He participated in many of the legendary "North-South" tournaments. [Two of the other participants were novelists Walter Tevis and Fritz Leiber. Tevis wrote "The Hustler," "The Color of Money" and a novel about a teenaged female prodigy, "The Queen's Gambit." Fritz Leiber was known for his fantasy and science fiction including "Farhfed and the Grey Mouser."]
Guthrie McClain also was a long time member of the Mechanics Board of Directors. After a long career in business, he retired to a Pulgas, a tiny town upstate but he made frequent trips back to the Bay Area to see family and friends.
On the final trip, he had dinner one night with his oldest and dearest friend, another longtime supporter of Bay Area chess, senior master Bob Burger.
Bob was a prolific writer and famed oeniphile. After the two had a sumptuous dinner of prime rib with several bottles of excellent red, they retired to the chess table with snifters of brandy.
The two must have played thousands of games during their long friendship. They had a habit of hurling caustic commentary at each other.
Mac played his move, then clutched his chest, and in the most dramatic way, lunged forward into the board. He was dead as a carp.
He'd died the perfect chessplayer's death. After a gourmet meal with several bottles of wine in the company of his dearest friend, then playing a game against that friend, dying right there at the board.
It's been over thirty years, but I miss him still.

Great Women Chess Players:  Week 7 – Alexandra Kosteniuk

This week we investigate the play of a modern Women’s World Champion. One who comes from the great Russian tradition of chess, but who embraces modern western culture. There have been great Russian and Soviet teams in both the men’s and women’s Chess Olympiad in the last century. The men are very famous names – Tal, Botvinnik, Karpov, Kasparov, etc. Yet the Russians have had great women players too, and two-time Women’s World Champion Alexandra Kosteniuk deserves her place in chess history.

Alexandra became Women’s World Champion in 2008 and won gold medals on the Olympic Teams in 2010, 2012 and 2014. Though she has earned her fame by chess ability, it is also her efforts off the chessboard that gets notice. She advanced chess by her attention to marketing and fashion. She was one of the first to have her own website and she pursued commercial opportunities, much like her countrywoman, tennis stars Maria Sharapova and Anna Kournikova.  Alexandra also lived in Miami for some years, following the trend of Sharapova and other Russian stars who live an international life and choose the US as one of their home bases.

Korchoi has chosen the French Defense, as he often did throughout his career. This line of the Rubenstein Variation gives Black the two bishops at the cost of slightly weakened pawn structure and a little less space. 7.Nf3 b6 8.Bc4 Bb7 9.Qe2 c6 10.a4!? Alexandra simply restrains Black on the queenside instead of 10. 0-0-0. 10...Nd7 11.Ng3 Qc7 12.0-0 Nf8?! [12...0-0-0 would be preparing for an all out battle.] 13.Nh5 Rg8 14.a5 b5 Diagram
15.a6! Bc8 This is not so pleasant, but neither is 15...bxc4 16. axb7. 16.Bd3 Rb8 17.b3 Rb6 18.c4 bxc4 19.Bxc4 c5 20.Rfc1! Bd7 21.Qe3 White has developed with great precision so Black is under pressure. The black king must stay in the center and the black rooks cannot get connected. 21...Rg6?! 22.dxc5 Bxc5 Diagram
23.Bd3! Rc6 24.Rxc5 Rxc5 25.Bxg6 hxg6 26.Nxf6+ Diagram
Alexandra has an extra pawn, a safe king and the attack. She brings home the point with forceful play. 26...Ke7 27.b4! Rf5 28.Rc1 Qb8 29.Ng8+ Ke8 30.h3 Nh7 31.Qc3 Qf4 32.Rd1 f6 33.Rd4 Qb8 34.Qd2 Nf8 Diagram
Black has been pushed back. The finish is near. 35.Qh6 Kf7 36.Qh8 Rf4 37.Nh6+ Ke8 38.Qg7 Diagram
Korchnoi resigned. He is losing more material and his king has no safe place. If 38...Rxd4 39. Qf7+ etc. 1-0

A classic closed Ruy Lopez position has arisen. Black has equalized here. 14.d5 c4 15.Nbd2 Nb7 16.Nf1 Nc5 17.g4?! This aggressive move has a downside that the dark squares are weakened on the white kingside. 17...h5! 18.N3h2 hxg4 19.hxg4 Qc8 20.f3 Nh7 Starting the maneuvers that give Black control of the kingside dark squares. 21.Ng3 Bg5 22.Nf5 Qd8 23.Kg2 [23.Nxd6?

Alexandra has met the Center Counter Defense with classic play and straightforward development. She has a nice edge from the opening. 10...Be7 11.Qg3 0-0 12.Ne2!? b5?! It was better to be solid with 12...Re8 or 12...g6. 13.Bh6 Ne8 14.Bf4 Ndf6 15.Be5 Bd6 16.a4 White has more space on the kingside and now the Black queenside becomes weak. 16...b4 17.a5 Qc7 18.f4 c5 19.c3 cxd4 20.Nxd4 Bxe5 21.fxe5 Nd7 22.Be4 Rc8 23.Nc6 bxc3?
