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.

And:

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: https://en.wikipedia.org/wiki/James_Eade

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 www.EadeFoundation.org

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

(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

(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

(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

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.

GM Nick de Firmian’s Column

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

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?
