GM Sam Shankland’s Live Commentary of TNM Highlighted Amazing Week at the Club!


GM Sam Shankland and Judit Sztaray provided some commentary of round 3 of the TNM

With our very own FM Paul Whitehead out on a well-deserved vacation, we needed to someone to fill the big shoes. Who other than our very own hometown hero and 2018 U.S. Champion GM Sam Shankland, who came on very short notice to deliver great commentary on the action on the first 10 boards.

The top board proved interesting for Shankland, as it showcased 2 of his students from the recently concluded U.S. Chess School held at Mechanics. In the end, FM Josiah Stearman provided a dominant performance in defeating NM Eric Yuhan Li. 

On board 1, UC Berkeley freshman FM Josiah Stearman playing white defeated NM Eric Yuhan Li. On Board 2, recent University of Virginia graduate and new Bay Area resident NM Jeevan Karamsetty (white) also showed strong play in defeating Ethan Boldi.

On Board 2, Jeevan Karamsetty, playing in his first TNM, remains perfect after his win over Ethan Boldi. With top seed FM Kyron Griffith taking a bye in round 3, it looks like the stage has been set for 2 players showing very strong play to face each other next week. 

Sriram Krishnakumar put on a technical clinic in his win over Winslow with the black pieces

Probably U.S. top 20 11-year old Sriram Krishnakumar, who defeated IM Elliott Winslow in impressive fashion, posted the most impressive win. I believe this is his first TNM and we hope he follows in the footsteps of Eric Li and Rui Yang Yan in Mechanics being a place to sharpen and hone the skills on Tuesday nights.

In the A/B section, Mansoor Mohammed continued his dominance of that section with a win over Adam Mercado. It was suggested by GM Shankland that we make a rule named the Mansoor Rule, which states that winners of the TNM must be promoted to the next higher section. While the USCF might have something to say about that, it may not be necessary, as he will be promoted by rating alone at the pace he is going. 

In the under 1600 section, we saw a broadcast match MI members loved to watch as MI regulars Jerry Simpkins and John Chan played an action packed battle that was eventually won by Simpkins. It was the chess equivalent of Hagler-Hearns, two middleweights trading blows and in full on attack. 

Jerry Simpkins and John Chan provided a board 10-fan favorite game that was enjoyable to watch.

It was a very fun evening. To watch the broadcast with GM Shankland’s commentary, please follow this link:

Tournament Director's Corner

I wanted to take this opportunity to address the issue of cell phones at the Mechanics Institute during tournament games. Although we have announced the rule prior to the round starts, I feel we need to elaborate exactly what the expectations are. When I started here, I could see that the rules regarding cell phone use were very liberally applied, as it was quite common for players to view texts, leave to take calls and have phones on at the table. As time has passed we have taken a firmer stand on enforcing the rule, and have on several occasions over the course of many tournaments, applied time penalties for those who had cell phones go off and have given warnings. We have seen the blatant use of phones during games go down, though it is a challenge to know of every single incident that occurs. We must rely on players to help us by both informing us of incidents of cell phones going off, and also of players taking a more active role in making sure they follow the rule of putting phones on silent, turning them off or turning them in to the TD. 

Here is the USCF rule regarding cell phone use:

20N. Electronic communication devices. Players are not allowed to leave the playing venue without permission from the arbiter. The playing venue is defined as the playing area, rest rooms, refreshment and smoking area, adjacent hallways and other places as designated by the arbiter/TD. Without the permission of the arbiter/TD a player is forbidden to have a mobile phone or other electronic means of communication in the playing venue, unless they are completely switched off. TD TIP: “Permission of the director” allows for maximum flexibility. No specific penalty is prescribed. In the absence of announced rules for a specific event, the standard penalties apply (see 20N1). Organizers are free to announce whatever penalty is appropriate for their event. In practice, the device ringing or making some other sound may be the only practical way to detect a cell phone—but this rule is not aimed at penalizing the noise; it is aimed at penalizing the possession of a communications device. 

20N1. Disturbing noise or disruption of games. Audible disruptive noises such as a cell phone ring tone, pager beep, alarms and other noises cause a disruption in the playing hall. These noises are often very loud and disturb the entire room. The following are guidelines for penalizing such disturbances: a. First offense standard penalty is to subtract 10 minutes or half the remaining time from a player’s clock, whichever is less. Variant: Depending on the importance of the event the standard penalty may be up to immediate loss of the game in progress. If a variant is used, it must be announced at the opening remarks for the event and posted prominently in the playing hall and at all entrances. b. Second (and subsequent) offense for the same player during the same event is loss of the game currently in progress. c. If the incident occurs in the playing hall, but after the offender’s game for the round is completed while other games are still in progress, then the above penalties apply to the subsequent round. In the case of a loss (e.g. second offense), that player is not paired for the next round. d. If the incident occurs after the game for the last round is complete while other games are still in progress, the offender is treated like a non-participating spectator and is ejected from the playing hall. Variant: Depending on the importance of the event and the disturbance created, the player may receive a ½ point total score penalty for prize distribution.

It is clear there is flexibility in assessing penalties for an infraction, but I think we have arrived at the time where all of us need to take a more active role in promoting a fair game and for protecting the integrity of the game, and this starts at the top. At the start of the event, I announced we are using USCF rules though it is FIDE rated. It is entirely possible to have both. We will announce before the start of every round that cell phones must be turned off and players are not allowed to have a cell phone on for the duration of their games. We will enforce the penalty of 10 minutes taken off their time or half the remaining time from their game, whichever is greater. 

I know this may sound excessive and/or uncomfortable, but this is quite standard in tournaments. We also have to all be part of the solution in making sure our club represents the highest in quality, and part of this is enforcement of the rules meant to protect all players. We as TD’s have the first responsibility in being more vigilant, and we will do more in this regard. But it will help us a great deal for players to follow the rules and to reach out to us whenever there is a problem in the game. We love our chess community and bringing exciting new things to the club, and it is an honor and privilege for us to be a part of all the great things in chess happening in San Francisco. 


Participants of the Berkeley Norm Event Visit Mechanics

The chess club had the honor of being paid a visit from several members of the Women’s IM norm event held at the Berkeley Chess School this past week. 

Players from the tournament stopped by our broadcast booth to record an interview before sight seeing around San Francisco

Special congratulations go to Uyanga Byambaa. She was the sole norm recipient of the event, obtaining her first WIM norm with her final round draw. Some of the best female players in North America were there, including IM Lisandra Ordaz Valdes from Cuba, IM Carolina Lujan from Argentina, WIM Agnieszka Matras-Clement from Canada, Saikhanchimeg Tsogtsaikhan and Uyanga Byambaa representing Mongolia, WGM Anjelina Belakovskaia, and WGM Carla Heredia, who organized the event. They enjoyed the visit and we think we may have many of them back for a future big event.

Wednesday Night Blitz starting up again!

Mark you calendar..... The Wednesday Night Blitz RESUMES at Mechanics’ Institute Chess Club next Wednesday Night (August 28th).
Sign-up starts around 6:30pm with round 1 starting at 6:45pm with the weekly event ending by 8pm (This is NOT the first Wednesday of the month!!!).
Also mark your calendars. The first Wednesday of each month will start 1 hour earlier at 5:45pm (entry 5:30-5:45) instead of 6:45pm  so that on the first Wednesdays of the month the Blitz can be the old double round format instead of the new single round format.  See attached flyer. Please note the new rule pertaining to how clock malfunctions will be dealt with.
Before summer break, the results of the last Wednesday Night Blitz were:
12 players
1st – Anna Matlin – 11pts $42
2nd – Arthur Ismakov - 9pts $25.20
3rd – Jules Jelinek – 8pts $16.80
Look forward to seeing everyone next week!

Nick de Firmian's Column - Magnificent Magnus

Week 3 – endgames

When one hears of a game in which some player ground down the opponent in an endgame it brings to mind a strong player who maneuvers and waits for his(her) lower rated opponent to make a mistake or two. It hardly seems like a noble way to win a game, and certainly sounds boring to watch. You understand it would be unprofessional for them to let the half points escape in a tournament or a match by not pressing, yet you think it’s not your favorite game to watch. However these games can be truly fascinating when the aggressor pushes to the limit until there is nothing left. Bobby Fischer would always play that way and his games had a stamp of purity and deep logic to them. Many times he would win those so called “drawn” endgames. Of course Magnus has done the same.

What happens though when the opponent is at the very top? Is it possible to grind down a 2800 player or a World Champion? The logical answer would seem to be no, such opponents are immune from that fate. Yet here we give two examples where that happens. How is that possible? One reason is the new approach Magnus has brought to chess – that these endgames are just chess positions and more complex than one would think. The other reason is that Magnus is at a level all by himself.


(1) Carlsen,Magnus - Aronian,Levon
London, 2012

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.d3 b5 6.Bb3 Bc5 7.Nc3 0-0 8.Nd5 Nxd5 9.Bxd5 Rb8 10.0-0 Ne7 11.Nxe5 Nxd5 12.exd5 Re8 13.d4 Bf8 14.b3 Bb7 15.c4 d6 16.Nf3 Qf6 17.Be3 Bc8 18.Qd2 Qg6 19.Kh1 h6 20.Rac1 Be7 21.Ng1 Bg5 22.Bxg5 Qxg5 23.Rfd1 bxc4 24.bxc4 Qxd2 25.Rxd2 a5

We have reached an endgame where Black is a pawn down but he has both rooks on the open files and bishop vs. knight. Additionally White's c-pawns are doubled. Hard to make progress against a strong opponent. 26.h3 Rb4 27.Nf3 Bf5 28.c5 Kf8 29.Nh2! Reb8 30.Ng4 Rb1 31.Rxb1 Rxb1+ 32.Kh2 a4

Black wants to set the white a-pawn as a target. There are losing chances for White too. 33.Ne3 Bg6 34.Kg3 Rb4 35.Kf3 Ke7 36.Ke2 Kd7

37.f3 We inserted a diagram to highlight the extreme patience Magnus has. It's very difficult to make progress so small moves and long maneuvers are required. 37...Rb5 38.Nd1 Rb4 39.c6+ Kc8 40.Nc3 f6 41.Ke3 Rc4 42.Ne2 a3 43.h4 Rb4 44.g4! Rb1 45.h5 Bh7 46.f4

Now White threatens f5, Nf4 and Ne6 with a winning outpost for the knight. Note Black cannot play 46...Bg8 47. f5 Bxd5? 48, Nc3 with a fork. Also note that Magnus stays aware to the danger of the Black a-pawn. 46...f5 47.g5 Rh1 48.Ng3 Rh3 49.Kf3

Magnus maintains control by mixing in tactical themes. Here 49. ..Bg8 50. Kg2 Rh4 51. Nxf5! will get a fork on e7. 49...hxg5 50.fxg5 g6 51.Re2 Kd8 52.hxg6 Bxg6 53.Re6 Bf7

54.g6! All the subtlety is over. Now White presses forward with the pawns. 54...Bxe6 55. fxe6 Rh8 56. Nxf5 would win. 54...Bg8 55.g7 f4 56.Kxf4 Rh2 57.Nf5 Rxa2 58.Rf6 Re2 59.Rf8+ The position looks dangerous for both sides, but here Aronian resigned. He saw 59...Re8 60. Nxd6! cxd6 61. c7+ is not difficult for Magnus. 1-0

(2) Carlsen,Magnus - Anand,Vishy [D31]
World Championship , 2013

1.c4 e6 2.d4 d5 3.Nc3 c6 4.e4 dxe4 5.Nxe4 Bb4+ 6.Nc3 c5 7.a3 Ba5 8.Nf3 Nf6 9.Be3 Nc6 10.Qd3 cxd4 11.Nxd4 Ng4 12.0-0-0 Nxe3 13.fxe3 Bc7 14.Nxc6 bxc6 15.Qxd8+ After an interesting opening the players have reached a level endgame. Most players in a World Championship match would be disappointed that their preparation didn't gain them anything. Magnus decides it's an endgame, so lets play. 15...Bxd8

16.Be2 Ke7 17.Bf3 Bd7 18.Ne4 Bb6 19.c5 f5! 20.cxb6 fxe4 21.b7! Rab8 22.Bxe4 Rxb7 23.Rhf1 Rb5 24.Rf4 g5 25.Rf3 h5 26.Rdf1

White has just a tiny edge due to the doubled rooks on the f-file. Nothing too much is happening. 26...Be8 27.Bc2 Rc5 28.Rf6 h4 29.e4 a5 30.Kd2 Rb5 31.b3 Bh5 32.Kc3 Rc5+ 33.Kb2 Rd8 34.R1f2 Rd4 35.Rh6 Bd1 36.Bb1!

Still the game is pretty level as Anand plays strong, active chess. Even so, Magnus keeps the game complicated with many posibilities. 36...Rb5 37.Kc3 c5?! More accurate was 37...e5, when White has to avoid some odd checkmates. Now Magnus has some edge to grind with. 38.Rb2! e5 39.Rg6 a4 40.Rxg5 Rxb3+ 41.Rxb3 Bxb3 42.Rxe5+ Kd6 43.Rh5 Rd1

White has an extra pawn, but all of Black's pieces are good. The question though is whether Black will draw or lose. 44.e5+! Kd5 45.Bh7 Rc1+?! [45...Ra1!] 46.Kb2 Rg1?! Now Anand needed to try the active 46...Re1! 47. Bg8+ Kd4 to stay in the game. His move is very natural, but is not enough against the Magnus press. 47.Bg8+ Kc6 48.Rh6+ Kd7 49.Bxb3 axb3 50.Kxb3 Rxg2 51.Rxh4 Ke6 52.a4! Kxe5 53.a5 Kd6

54.Rh7! The rook here will shepard the a-pawn to a7, when the rest is easy. Anand cannot defend against two rook pawns when one is so far advanced. 54...Kd5 55.a6 c4+ 56.Kc3 Ra2 57.a7 Kc5 58.h4 1-0
