Round 2 of TNM Showed Upsets and Action on Broadcast Boards!
Round 2 of the TNM saw many tricks from the underdogs, and viewers were treated to some amazing games. The most action was delivered on board 1, as NM Michael Walder upset FM Kyron Griffith in a very sharp game that left even the players on board 2 (yours truly and Kristian Clemens), at times abandoning our own game to jointly view the bombs lobbed. In the end, Michael Walder was able to close the show and pull off an amazing upset of a previous TNM champion.
NM Michael Walder won a brilliant fight on board 1 against FM Kyron Griffith
With Gianluca Pane calling in for his game against NM Eric Li, and Li electing to take the forfeit win to stay home and work on school work, I took the opportunity to lay it all out on the line in full public view and play an extra rated game against Kristian Clemens, who just recently won the A section in Reno. While I regret I did not play more creatively and dynamic, I also did not hang my face and kept my position to hold a draw. It was fun to play however, and am glad I had that opportunity.
Another exciting game that went down to the wire was between Ethan Boldi and IM Elliott Winslow. It was one of the final games of the evening, and viewers got to see the finale. During the time scramble, Winslow made an error in holding an already difficult position and Boldi came up with the upset win.

Board 9 from the AB section saw an amazing performance from MI regular Jerry Mays, who played a fantastic game to upset Ashik Uzzaman, one of the section favorites to win. It was a terrific perfomance by Mays, who stepped up and perfomed with the world watching.
On Board 10 in the under 1600 section, Mateo Hansen withstood the all out attack from the always entertaining Jerry Simpkins and cruised to an early win.
Many players returned for round 2, and we had well over 100 people at the club in games or playing skittles in the Annex. It was a great evening of chess, made even better by the special guest appearance of former MI Chess Director Jim Eade. He joined Paul in the broadcast and talked about the games. It was an entertaining broadcast and evening, and we wish him well, as he is now working to help suport players with disabilities playing and learning the game, and organizing chess events and ways to promote the game within that community.

Inaugural CalChess Rapid and Blitz Championships a Monumental Success!
The newly created CalChess Rapid and Blitz Championships, which will be organized by the Mechanics' Institute for 3 years, was held over the weekend of October 26-27 in what we dubbed Action Weekend. In all, 80 players played the Rapid on Saturday and 60 players the Blitz on Sunday, crowning its first ever state champions in this category.
2019 CalChess Rapid Championship
18 titled players were among the 80 competing to be the state rapid champion, which was formed in 3 sections. The rapid championship, which was G/15 +2, was won by IM Prasanna Rao, who took clear first with 6/7 over GM Daniel Naroditsky and IM Teddy Coleman at 5.5/7. The tournament was exciting, as it brought out our very own 3-time U.S. Champion GM in Residence Nick de Firmian, who tied for 6th at 4.5/7 and former MI chess Director IM John Donaldson. This 7 round championship tested nerves, as for many their sense of time management came under serious stress as there are not that many live G/15 +2 events in the Bay Area. Players adjusted quickly, but ultimately, their ability to play fast in the final few minutes often made the difference. In this event, IM Prasanna Rao showed everyone he is a force to be reckoned with. He had victories over GM Steven Zierk, IM Teddy Coleman and IM Michael Song. His ability to close the show against these players made the difference, as he drew GM Daniel Naroditsky and secured a final round draw against GM Nick de Firmian.
Anika Rajaram and Niko Pompe played an epic time scramble to the excitement of the audience.
In the 1500-1999 section, Rohan Rajaram showed the power of youth as he took sole first and was the new champion of the section with 6/7. Devanshi Rathi took clear second with 5.5/7, and Alan Finkelstein and Jacob Chiang tied for third with 5/7.
GM Prasanna Rao (left) drew GM Nick de Firmian in the final round, securing 1st place. GM Daniel Naroditsky defeated GM Steven Zierk on board 2 to tie for 2nd place.

2019 CalChess Blitz Championship
The CalChess Blitz Championship brought 60 players to fight for the title of first ever blitz state champion in one of 3 sections. The open section was ultra competitive, drawing 4 Grandmasters, 6 International Masters and 12 other masters. It was an electrifying event, with high drama in games and some of the most insane blunders that are typical of such a fast time control. When the smoke cleared, GM Daniel Naroditsky came out on top, taking clear first after a final round victory over NM Beilin Li with 7.5/9. Tied for 2nd-3rd place were GM Zviad Izoria and GM Conrad Holt with 7/9. The event was broadcast on our 10 DGT boards with live commentary by FM Paul Whitehead.

50-move rule - What to do under 5 minutes?
I certainly had a super fast game to count this past Sunday, so I opted counting in head and noting every 10 moves on my hand due to lack of paper around me :)

Wednesday Night Blitz Update
A Comedy of Errors at the 2019 CalChess Blitz Championships.
By FM Paul Whitehead
The 2019 CalChess Blitz Championship, hosted by the Mechanics’ Institute Chess Club last Sunday, was won narrowly, if not unsurprisingly, by GM Daniel Naroditsky with 7.5 out of nine. His play was more consistent than his rivals, but he had a nasty scare in the 4th Round vs. IM Christopher Yoo:
Here 26…g3! Would have broken through. Instead the young prodigy chose 26…Nf5?! And after 27.Rxe4 Rxe4 28.Nxe4, White was back in the game and went on to win.
However, this column is dedicated to the all-too-human capacity to err, blunder, hang one’s face – whatever you want to call it. It makes for interesting chess, and gives some solace: we all fall down.
IM Prasanna Rao was returning to the MI after winning the CalChess Rapid Championship the previous day. Maybe he didn’t get enough sleep: in the very 1st round he blundered into a mate in one against Expert Jamal El Chamieh:
Here Black played the “sneaky” 34…c5! White repositioned his Queen with 35.Qf4?? and was mated on the spot with 35…Qxg2#!
A very similar “idea” occurred in the last round game between Expert Adrian Kondakov and IM Ladia Jirasek:
Young Adrian has been on the ropes the entire game, but kept making moves. Here Ladia can wind up the game (eventually) with 29…Nf6! And if 30.Qxb4 Ne4+ 31. Kb3 Rb8 wins. Instead Black played 29…Rb8?? and was stunned by 30.Qxg7#!
Expert Jamal El Chamieh continued his giant-killing ways in the second round when FM Kyron Griffith went for broke in this position:
White is 2 pawns down, but it’s bishops of opposite colors and very drawish after the safe 38.Qf3. Instead there was a quick flurry of horrendous mistakes: 38.Rc1?? Qf2+? (38…Qb2+! Wins the rook) 39.Kh3?? (Kyron can still hang on with 39.Kh1) Qxg3 mate!
“Every Russian Schoolboy Knows.”
Onlookers were amused (and some quite aghast) by this situation, reached between the two Blitz Mavens, Experts Arthur Ismakov and Jules Jelinek in round 3:
“Every Russian schoolboy knows…” is an old as the hills chess saying, but I guess Arthur’s schooldays are long forgotten, and he uncorks the awful 65.Rc4?? (65.Rb3, the well-known 3rd-line defense, is correct). After 65…Kh3 Jules soon pulled out a win on time – before he could “forget” how to win the upcoming Lucena Position!
Back to tournament winner GM Daniel Naroditsky, who enjoyed showing me this miniature victory over IM Vladimir Mezentsev from Round 2:
Black is already on the ropes: he’s behind in development and a piece down for only 2 pawns. But at least he could make a fight of it with 14…b5. Instead he had to resign after 14…d6? 15.Nb6. Oops!
In the 8th Round GM Conrad Holt as White was enjoying a nice advantage after 26 moves over GM Steven Zierk in the following position:
Holt just couldn’t bring himself to make a move, and was brought out of his trance only when Zierk called “Time!”
By the end of the tournament I felt I was watching a series of fast-motion train wrecks. Here is an incredible (but true!) turn-around between IM Vladimir Mezentsev as White vs Oleg Shakhnazarov in Round 9:
White has just played 31.Qh6. Black “naturally” defends against the threatened Qg7 mate by replying with 31…Qf8. Now White avoids the exchange of Queens with 32.Qh4?? This not only overlooked Black’s reply 32…Rxh4, forcing White’s resignation, it overlooked the fact that he could have played 32.Qh8 mate!
It might be true, as Alexander Pope said, that “To err is human, to forgive divine.”
But after seeing some of these moves I’m not so sure.

GM Nick de Firmian's Column
Great Women Chess Players: Week 2- Irina Krush
This week we investigate the games and life of the strongest American woman player in history, Irina Krush. Irina was born in the Ukraine but moved to Brooklyn at 5 years old, so she is very much an American chess product. She learned chess the same year she came to America and progressed rapidly. At 14 years old she became the youngest ever US Women’s Champion. That championship was in 1998 in Denver Colorado, where coincidentally your author was the men’s champion. Irina has won the Women’s championship a record 7 times! She is also one of the women who has gained the title of (men’s) Grandmaster and has participated on the US Women’s Olympic teams regularly since 1998. In 2016 she appeared on the Steve Harvey show with Hillary Clinton, where she answered questions regarding her chess career.
Irina plays straightforward, aggressive, classical chess. She has won so many women’s events around the world, and recently a notable event in Berkeley, just across the bay. We give three of her games against very strong grandmasters in which she shows she is not of the weaker sex! Her game against Victor the Terrible involved a bit of luck, but the other two were simply tours de force.

This, P.Negi's "alternate" system against the main line Najdorf Sicilian, can be quite annoying for Black. Another advantage is White can also play this with ...h6 and Bh4 tossed in (with some differences). Walder prepared well and caught Griffith out. 10...e5 [10...Ne5 is the other try, but White has sharp pressure on e6 after 11.Qh3] 11.Nde2! White "has plan" (Boris Badenov). [11.Nb3 has been played a fair amount with less than success.] 11...b5 12.Bxf6 Nxf6 13.Nd5 Nxd5 14.exd5! Bb7 [Somebody won a game with 14...e4 15.Qxe4 0-0 but White was all but winning.] 15.Ng3 Rc8 16.Bd3 Qc5 17.Be4 All according to Negi. 17...b4 [who gives only 17...Bg5+ 18.Kb1 Qe3 19.Qh5+/=; Stockfish gives 17...f6 as "0.00" after 18.Qh5+ Kf8 19.Rhf1 b4 20.Rf3; but 17...f6 18.Nh5 0-0 White has a nice slow buildup with Kb1/h4/g4/Rdg1 or Rhg1 and eventually g4-g5.] 18.Kb1 Bg5?! Just gives White a free move towards the attack. [18...f6 19.Nh5 (19.Qh5+) 19...0-0 20.h4] 19.h4 Bd8?! 20.Nh5 Now the computer makes White winning. 20...Kf8 21.g4 [21.f6 g6 22.Ng7] 21...Bb6 22.g5 Qe3 23.Qg4 Definitely no queen trade here! 23...Rc7 24.Rhe1 Qc5 25.f6 g6 26.Ng7 Bc8
