FM Kyron Griffith wins rematch of epic Addison Memorial battle against FM Ezra Chambers to take share of the SummerTNM lead.

Griffith and Chambers gave commentator FM Paul Whitehead a break in the broadcast as they broke down their game for the audience

The best have risen to the top, and FM Kyron Griffith has shown he has not lost form since his Addison Memorial victory, defeating FM Ezra Chambers to take a share of the Championship section lead with 5.5/7. 

FM Andy Lee is the other player sharing the lead with Griffith after he claimed a forfeit win against NM Conrado Diaz on board 2. Although this was an unfortunate way to score a point, the public did benefit from the result as he sat in with Paul Whitehead and partnered with him for the evenings commentary. 

This sets up a championship battle next Tuesday night as Griffith and Lee will square off for the summer TNM title. FM Chambers, IM Elliott Winslow and Kevin Kuczek are at 5/7 and can still catch up for a share of the championship. Next week is championship Tuesday and we will bring you the action as always, live from downtown San Francisco!

In the A/B section, Mansoor Mohammed tightened his grip on the lead with a victory over Gaziz Makhanov. He is the sole leader at 6/7 and in control of his destiny.


Mansoor Mohammed (left) can win the A/B title next week after a great performance against Makhanov

Right behind him is Ella Papanek and Alexander Huberts at 5.5/7. 

In the under 1600 section, Gregory Rousso and Romeo Barreyro are tied at 6/7 for the lead. They played each other to a draw in round 6, so they will each be watching each other’s game next week. John Chan is only a half point behind at 5.5, with many players at 5. It will be a wild finish in that section with lots of action.

Tournament Director's Corner
by Abel Talamantez

During the 7thround of the Summer TNM, two players in the championship section had not yet showed up for their game. We had not received word that either was not going to make it, and they were both players that we would never think would be no shows. After 20 minutes, the first player showed up. The 2ndplayer showed up 10 minutes after that. How did the TD handle the time?

USCF Rule 16K states:

16K. Both players late. If both players arrive late, the first to arrive must split the elapsed time before starting the opponent’s clock. For example, if the first player to arrive is 40 minutes late, the clocks should be set to reflect 20 minutes of elapsed time on each side. See also 13F, Late arrival by both players; and 13D, Late arrival for game.

I had started whites clock at 6:30 and the first player arrived at 6:50. What I did was I used the clock to figure the elapsed time, then reset the clocks, deducting 10 minutes from each side (20 minutes total late) and the player made his move and started the clock. The other player arrived approximately 10 minutes later and they played their game.
​


Good Luck Rui!!

TNM player Rui Yang Yan requested a bye for rounds 7 and 8 of the TNM for a better reason than most. She is currently playing in the 2019 U.S. Junior Girls Championship! At age 12, she is one of the youngest competitors in the field, and currently ranked #1 in the country for her age. I took the picture below after her final round victory in the 2018 ChessKid.com National Online Championship, which clinched her the championship in her age group. It is one of my favorite pictures. We wish her the best of luck in St. Louis!!

Also competing in this event is Bay Area phenom Rochelle Wu, who also just recently competed in the U.S. Cadet Invitational as the only girl in the field. 

We are honored and happy to support and promote our local talent, and these two girls will be the ones many others will look up to over the next few years and beyond. Best of luck to our homegrown players and we thank them for representing our community.

Friendly Rivalries, Part 13

Familiar Rivals and Unfamiliar Strangers

By FM Paul Whitehead
 

The late 1970’s were a crucial time in my development as a chess player, and I finally became a master at the age of 16 in 1977.  I had one published rating of 2260, and then went over 2300 - never to return, it seems. I had finally figured a few things out, the foremost being: always play aggressively, and always play to win. I was lucky to have strong players to knock heads with in the San Francisco Bay Area, and playing in the U.S. Junior Closed twice, in 1977 and 1978, and at Lone Pine twice, in 1978 and 1979, were invaluable experiences for me, important testing grounds for my skill and talent.

I’ve already shown a bunch of games in past articles from those days, and here’s a few more: some memorable wins over familiar rivals and unfamiliar strangers from those days, but tough players all!
 

(1) Tisdall,Jonathan D (2375) - Whitehead,Paul A [E94]
USA-ch Juniors Denver (6), 1977

Jonathan Tisdall became a Grandmaster in 1993, and this was our only encounter. Black saddled White with a weak pawn with 25...Nxa4, then won it fair and square a few moves later. A long struggle ensued, and eventually White cracked after Black's King joined in.  1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Be2 0-0 6.Nf3 e5 7.0-0 Nbd7 8.Be3 Ng4 9.Bg5 f6 10.Bh4 Nh6

11.Qd2 Nf7 12.Rad1 c6 13.h3 a5 14.Qc2 Qe8 15.Rfe1 Nh6 16.dxe5 dxe5 17.a3 Qe7 18.Bf1 Nf7 19.Na4 Nc5 20.Nb6 Ra7

21.b3 Na6 22.Ra1 Be6 23.Qd2 Nc5 24.Qe3 Ra6 25.Na4 Nxa4 26.bxa4 c5 27.Rab1 b6 28.Rb2 Bd7 29.Reb1 Rb8 30.Ne1 Nd6

31.Qd2 Bxa4 32.f3 Qc7 33.Bf2 Rd8 34.Qc3 Nc8 35.Rd2 Rxd2 36.Qxd2 Ne7 37.Be2 Ra8 38.Qb2 Rb8 39.Nd3 Nc6 40.Bd1 Bxd1

41.Rxd1 Rd8 42.Qb3 Nd4 43.Bxd4 Rxd4 44.Nf2 h5 45.Rb1 Qd6 46.Rd1 Bh6 47.Rxd4 Qxd4 48.Kf1 Be3 49.Nd1 Bc1 50.Nf2 Kg7 

51.a4 Be3 52.Nd3 Qa1+ 53.Ke2 Bd4 54.Ne1 Qc1 55.Qd3 Kf7 56.Qb3 f5 57.Qd3 Kf6 58.Qb3 Kg5 59.g3 h4 60.gxh4+ Kxh4

0-1

 

(2) Whitehead,Paul A (2332) - Watson,John L (2319) [A04]
Berkeley May Day, 1977

John Watson is a well known International Master and author. I believe this is our only game. Black makes some risky moves (8...Bf6 and 13...g5) in an attempt to mix it up, but White plays positively, and when he uncorks 24.Rxe6! gaining a pawn and the 2 bishops the end is not far off. Black then blunders a piece in time-trouble. 1.e4 c5 2.Nf3 e6 3.d3 Nc6 4.g3 g6 5.Bg2 Bg7

6.0-0 Nge7 7.c3 e5 8.Nh4 Bf6 9.f4 exf4 10.Bxf4 d6

11.Nd2 Be6 12.Ndf3 h6 13.Be3 g5 14.Nd2 gxh4 15.Rxf6 hxg3

16.hxg3 Qd7 17.d4 cxd4 18.cxd4 d5 19.Rc1 Rg8 20.Bf2 0-0-0

21.Qa4 Kb8 22.Nb3 dxe4 23.Nc5 Qc7 24.Rxe6 fxe6 25.Nxe6 Qb6

26.Nxd8 Rxd8 27.Bxe4 Nd5 28.Rc5 Nce7 29.Qc2 Qe6 30.a3 Qg4

31.Bg2 Ka8 32.Qe4 Qd1+ 33.Qe1 Qh5 34.Qxe7

1-0

 

(3) Cleghorn,Peter (2330) - Whitehead,Paul A (2355) [B44]
San Francisco Bagby San Francisco (6), 1978

Peter Cleghorn came down from Alaska and became a fixture in the S.F. Bay Area chess scene for years, playing once at Lone Pine and in several Northern California State Championships. We played a few times, with the honors more or less split if I recall. Here Peter doesn't seem to understand the nuances of the opening and becomes too weak on the dark squares. Finally he collapses on the 40th move, but it was all over anyway. 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 e6 5.Nb5 d6 6.c4 Nf6 7.N1c3 a6 8.Na3 Be7 9.Be2 0-0 10.Be3 b6

11.0-0 Bb7 12.f3 Re8 13.Na4 Nd7 14.Nc2 Rc8 15.Bf2 Nce5 16.Ne3 Qc7 17.Rc1 Qb8 18.Nc3 Ba8 19.Qd2 Nf6 20.Rfd1 Red8

21.b3 Ng6 22.Bf1 Rc7 23.Qb2 Rcd7 24.Rc2 h5 25.Rcd2 h4 26.h3 Nh5 27.Ng4 Bg5 28.Be3 Bxe3+ 29.Nxe3 Qa7 30.Kf2 Qc7

31.Ne2 Bc6 32.Qc3 Rb8 33.Qb4 a5 34.Qa3 Rbd8 35.Nd4 Ng3 36.Nxc6 Qxc6 37.Nc2 d5 38.cxd5 exd5 39.Nd4 Qf6 40.Kg1 dxe4

0-1

 

(4) Whitehead,Paul A (2320) - Verduga Zavala,Denis (2355) [B96]
Lone Pine op Lone Pine (9), 1978

At Lone Pine in 1978 I scored 4-5 against some tough players, but it was on the whole a disapointing result. However, this last round win against Denis Verduga, an International Master from Ecuador, did a lot to lift my spirits. In a topical (at the time) variation of the Najdorf both players err, but Black erred last, and was soon knocked out. 1.e4 c5 2.Nf3 d6 3.d4 Nf6 4.Nc3 cxd4 5.Nxd4 a6

6.Bg5 e6 7.f4 b5 8.e5 dxe5 9.fxe5 Qc7 10.Qe2 Nfd7

26.Rd2 Qf7 27.Qe5 Kc8 28.Qxg5 Rxc3!? 29.bxc3 Qxa2-/+ 30.Rde2 Nb6?

In time-trouble Black drops a rook.  [30...Nc6 was the way to go. Now it's all over.] 31.Qc5+ Kb7 32.Qxf8 N8d7 33.Re7 Qa3+ 34.Kd1

1-0

 

(5) Harari,Zaki - Whitehead,Paul A (2365) [E97]
Cal Masters Berkeley (6), 1979

Zaki Harari lived in the S.F. Bay Area for awhile, and was a dangerous opponent. White's 10.f4?! was super aggressive if not neccessarily good, and the game remained very sharp to the very end. Black finally went on a long King-Hunt, culminating in the brilliant and quiet 43...Kf7!!  1.d4 Nf6 2.c4 g6 3.Nf3 Bg7 4.Nc3 0-0 5.e4 d6 6.Be2 e5 7.0-0 Nc6 8.d5 Ne7 9.Nd2 c5 10.f4 exf4

41.Kf4 Qh6+ 42.Ke5 Re2+ 43.Ne4 Kf7

0-1

 

(6) Blocker,Calvin (2435) - Whitehead,Paul A (2365) [A26]
Lone Pine op Lone Pine (8), 1979

Calvin Blocker is an International Master (1981) from Cleveland. This is our only game, a tough fight from Lone Pine 1979, where I scored a very disappointing 3-6. Calvin might have won this game if he'd found 35.Nd5! instead of 35.Ra3?? which lost on the spot. 1.c4 g6 2.Nc3 Bg7 3.g3 d6 4.Bg2 e5 5.d3 Nc6

6.Nf3 f5 7.0-0 Nf6 8.Rb1 a5 9.a3 0-0 10.b4 axb4

Nick de Firmian's Column: Learn from the World Champions

This week: Anatoly Karpov
 

Karpov was born on May 23, 1951, in Zlatoust in the Urals region of the Russian, He learned to play chess at the age of 4 and was a great talent from an early age. A product of the Soviet School of Chess, he was accepted to Botvinnik’s prestigious chess school, though famously Botvinnik said, "The boy does not have a clue about chess, and there's no future at all for him in this profession.” Nonetheless Karpov became World Junior Champion at 18 years old, then next year won an international tournament in Stockholm with 10/11 followed by a great victory at the Alekhine Memorial in Moscow. He qualified for the Candidates Tournament in 1973 and upset the old guard by winning three matches to challenge for the World Championship. Bobby Fischer refused to defend his title in 1975, making Karpov the official World Champion. Karpov silenced any doubters over the next ten years by winning almost every tournament (and every match) he played in. 

Karpov’s style is principled positional chess, accented by an underlying aggression that many observers  miss. Karpov would maneuver in small ways, then suddenly his opponent has nowhere to go. He was famous for taking the important squares on the board and for his superb endgame skill.

A quote from Karpov explains his chess philosophy - “Let us say that a game may be continued in two ways: one of them is a beautiful tactical blow that gives rise to variations that don't yield to precise calculations; the other is clear positional pressure that leads to an endgame with microscopic chances of victory. I would choose the latter without thinking twice. If the opponent offers keen play I don't object; but in such cases I get less satisfaction, even if I win, than from a game conducted according to all the rules of strategy with its ruthless logic.”

His performance Linares 1994, a super tournament of all the world’s elite, is often called the best performance of all time as he scored 11/13.  Karpov visited the Mechanics’ Institute club in 2000. The above picture is him in the club with trustee Mark Pinto and Ewelina Krubnik (who is now grown up and teaches the women’s chess class on Sundays).

 

(1) Karpov,Anatoly - Korchnoi,Victor
Candidates Final, 1974

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6

Korchnoi chooses the aggressive Dragon Variation against his young opponent, anticipating a sharp tactical middle game. 6.Be3 Bg7 7.f3 Nc6 8.Qd2 0-0 9.Bc4

Karpov doesn't back down and plays the challenging Yugoslav Attack with castling on opposite wings. 9...Bd7 10.h4 Rc8 11.Bb3 Ne5 12.0-0-0

12...Nc4 Nowadays the theorectically preferred line is 12...h5 - the Soltis Variation (named after New York grandmaster Andy Soltis. That move slightly slows the white attack on the kingside. 13.Bxc4 Rxc4 14.h5 Nxh5 15.g4 Nf6

16.Nde2! Karpov's "safe" move holds the queenside. It is better than the older line 16. Bh6 Bxh6 17. Qxh6 Rxc3! when black gains good counterplay against the white king. 16...Qa5 17.Bh6 Bxh6 18.Qxh6 Rfc8 19.Rd3 Another typical Karpov move, paying close attention to defense before proceeding with the attack. 19...R4c5?! 

20.g5! Rxg5 21.Rd5!

Suddenly White has a ferocious attack for the two pawns. Korchnoi, a great defender, tries his best to escape. 21...Rxd5 22.Nxd5 Re8 23.Nef4 Bc6

24.e5!! The scintillating blow is crushing. 24...dxe5 25. Nxf6+ exf6 26. Nh5 is soon mate. 24...Bxd5 25.exf6 exf6 26.Qxh7+ Kf8 27.Qh8+

Korchnoi resigned as 27...Ke7 28. Nxd5+ Qxd5+ 29. Re1+ wins. 1-0

 

(3) Karpov,Anatoly - Shirov,Alexey
Biel, 1992

1.d4 "I like 1. e4 best, but my results have been slightly better with 1. d4." - Karpov 1...d5 2.c4 c6 3.Nc3 Nf6 4.e3 e6 5.Nf3 Nbd7 6.Qc2 Bd6 7.Be2 0-0 8.0-0

A typical queen's pawn, Slav opening. Karpov has always relied on his middle game skills rather than the super openings that Kasparov or Fischer would produce. 8...dxc4 9.Bxc4 b5 10.Be2 Re8 11.Rd1 Qc7 12.b3 e5 13.h3 Bb7 14.Bb2 a6 15.dxe5 Nxe5 16.a4

White has just a modest edge from the opening, but the position is full of possibilites. 16...Rad8?! (16...b4) 17.Ng5! Qe7 18.Nce4 Nxe4 19.Nxe4 Bb4 20.Ng3 f6?!

21.Bxe5! This is a classic Karpov move. It is unorthodox in that it gives up the two bishops, but it has a venomous point that Black becomes weak on the kingside light squares. 21...Qxe5 22.Bd3 h6 23.Bg6 Rf8 24.Nf5

One starts to feel the strong grip of white square control. Black is in trouble. 24...c5?! Good advice is hard to find here, but this allows White to invade. 24...Kh8 would limit the damage. 25.axb5 axb5 26.Ra7! Qc7 27.Nh4

Black cannot defend anymore. Note how the black bishop on b4 is out of play at this critical moment. 27...Rxd1+ 28.Qxd1 Ra8

29.Qg4! Qc6 30.Rxb7! Qxb7 31.Qe6+ Kh8 32.Be4

Shirov resigned as Ng6+ will be a killer. In this game Karpov showed fantastic control of the squares. 1-0

 

(2) Karpov,Anatoly - Spassky,Boris
Canditates Semifinal, 1974

1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 d6 6.Be2

This simple move was always Karpov's preference against the Sicilian. 6...Be7 7.0-0 0-0 8.f4 Nc6 9.Be3 Bd7 10.Nb3!

This retreat keeps Black cramped. 10...a5?! 11.a4 Nb4 12.Bf3 Bc6 13.Nd4 g6 14.Rf2! e5?! 15.Nxc6 bxc6 16.fxe5 dxe5 17.Qf1 Qc8

Black's position is a little lose, but could become active if White is not careful. 18.h3 Nd7 19.Bg4 h5 20.Bxd7 Qxd7 21.Qc4 Bh4 22.Rd2 Qe7 23.Rf1 Rfd8

At first site this looks like a normal position between two great players. Both sides are completely developed and seem to control equal amounts of the board. Now follows a classic, very deep Karpov move which highlights the flaws of the black set-up. 24.Nb1!! Qb7 25.Kh2 Kg7 26.c3 Na6 27.Re2

This fantastic manuever has left White in control. The black knight has been driven from its great outpost of b4. The white knight is calmly headed to the kingside after which all the white pieces have their ideal spots. 27...Rf8 28.Nd2 Bd8 29.Nf3 f6 30.Rd2

White's set-up is a picture of harmony now. Black cannot stop the coming invasion. 30...Be7 31.Qe6 Rad8 32.Rxd8 Bxd8 On 32...Rxd8 33. Nxe5! 33.Rd1 Nb8 34.Bc5 Rh8

35.Rxd8!

Spassky resigned as 35...Rxd8 36. Be7 finishes things. 1-0

2019 Summer TNM Games Round 7

Annotations by GM Nick de Firmian and IM Elliott Winslow

And after more or less deciding on 5...d5, if 6.a3, which bishop move was I going to play? I determined, and promptly reached out and grabbed -- the bishop! So now I had to move it. After quite a bit of thought, I played. [5...d5 6.a3 Be7 (6...Bxc3+) ; 5...Re8 6.a3 Bf8; 5...b6; 5...c6!?] 6.Ng3?! Now he's under a sort of psychological pressure. He "has" to show (1) my move is bad (2) he can "get by" without a2-a3 (or else we have just transposed into some line where I was merely retreating my bishop from attack). Meanwhile, he's in a position I rather doubt he'd prepared for! But objectively he should be able to achieve an opening plus. [I was sure that advantage would be found in either 6.d5; or 6.e4] 6...d5 7.cxd5 Nxd5 8.Bd3 c5 9.0-0 Nc6 10.Nxd5 Qxd5 11.Be4 Qd6 12.Qc2 cxd4 13.Rd1 f5 14.Bxc6 Qxc6 15.Qxc6 bxc6 16.exd4 g5 17.Bd2 Rd8 18.Bc3 Ba6 19.Re1 Kf7 20.Nf1 Bf6 21.Rad1 Rd5 22.Ne3 Rd7 23.Nc2 Rad8 24.Ba5 Rc8 25.Bb4 Rb8 26.b3 f4 27.Bc5 Rbd8 28.Nb4 Bb7 29.Nd3 Bxd4 30.Bxd4 Rxd4 31.Ne5+ Kf6 32.Rc1 R8d6 [32...R4d5! 33.Ng4+ (33.Nxc6 R8d6 34.Nb4 (34.Nb8 a5) ) ] 33.h3 [33.h4 gxh4 34.Ng4+ Ke7 35.Ne5 h5 36.Nf3 R4d5] 33...R4d5 [33...h5!] 34.Nc4?! [34.Ng4+ Ke7 35.Ne5 h5 36.h4 gxh4 37.Ng6+ Kf6 38.Nxf4 Rf5=/+] 34...Rd7 35.b4 Ba6 [35...c5! 36.b5 Rc7 37.a4 (37.Na5 Ba8 38.a4 Re5! 39.Red1 Re4) 37...Rd4 38.a5 Bd5 39.b6 axb6 40.Nxb6 Bb7-/+] 36.Na5 [36.a4!?] 36...Bb5 37.Nxc6 [37.a3] 37...a6 [37...h5; 37...Rc7 38.Na5 Rxc1 39.Rxc1 Rd2] 38.Na5 Rd2 39.Ra1 Rb2 [39...Ba4!-/+ 40.Nb3 Bxb3 41.axb3 R7d6 42.Ra5 Rb6] 40.Nb3 Bc4 41.Nc5 Rd4 42.a3 Aha!
