2020 Max Wilkerson Memorial TNM Round 3! 

Clear Leaders in Championship and A/B Sections After 2 Rounds. 5 players Remain Perfect in Stacked u/1600 Section

The third round of the Max Wilkerson Memorial Tuesday Night Marathon has clear leaders in the first two sections. However, it may only be for the moment, as many strong contenders have four more rounds to make moves for a share of the prize. In the u/1600 section, five players are 3-0 after the night's action. Even with 47 players in that section, it looks like we may have a clear prize winner when it is all over.

In the Championship section, it was a battle of some of the best kids in the bay as UC Berkeley freshman Josiah Stearman (Go Bears!) had white against 12-year old phenom Rui Yang Yan, the 2019 World Cadet u/12 girls bronze medalist. After a game where Stearman put a lot of pressure but Rui seemed to stabilize, a blunder on move 42..Rxf3 led to her losing the game and Stearman alone in clear first at 3/3. On board 2, FM Kyron Griffith and IM Elliott Winslow played to a draw after Kyron was able to hold what was a lost rook and pawn endgame. As with endgames, one single move can mean the difference between a win and a draw, and such was the case here after Winslow played 53. Rg1+. This draw puts both players at 2.5/3 for the tournament.

The other story we have been following in the Championship section is another 12-year old, Nicholas Weng. He had a terrific start to his TNM career with two big wins, but he finally got upended by veteran Mechanics' player David Askin in a very sharp game that included clever finishing technique. Askin also sits at 2.5/3 while Weng is at 2/3. 

These games can be viewed at the end of this newsletter and can also be viewed online by following the Chess24 link here:

In the A/B section, Bruce Ricard stands alone on top with 3/3 after his victory over Gagik Babayan. The position looked fairly harmless until Babayan blundered a pawn on move 20, then compounded the error the very next move by blundering the exchange. Four very tough players are close behind at 2.5/3 including Rudolph Breedt, Adam Mercado, Nicholas LaTourette, and Bob Drane.

In the u/1600 section, Ilia Gimelfarb used nice tactics to get a relatively quick win against Ivan Rothman and stary perfect with 3/3. Also winning and remaining perfect were Jahaan Ansari, Eitan Neugut, Charles James and Julian Sachs-Weintraub. 

We also had a very special guest for our commentary helping out Paul, IM Kostya Kavutskiy! The pair made a great commentary duo, and I think it would bode well for the chess community to see these two again in the future bringing the games to life over the internet.

IM Kostya Kavutskiy and FM Paul Whitehead provided amazing commentary for the third round

2019 FIDE Botvinik Award and 2019 Neil Falconer Award Presentation at Feb 4 Tuesday Night Marathon!

We will have a truly special evening of chess on Tuesday February 4th, 2020, as we will be honoring two important achievements, one for longevity and commitment to service in training and coaching, the other for the future of American chess in the beginning stages of great things to come. 

We will present the 2019 FIDE Botvinik Award trophy to IM John Donaldson, legendary Chess Director of the Mechanics' Institute and Captain of the U.S. Olympiad team. After that, we will present the 2019 Neil Falconer award to this years recepient IM Christopher Yoo! The Falconer award is given to the highest USCF rated player under 18 years old, which Christopher earned this year (at 13 years old) with a rating of 2531. He will be given a check for $2531 on that Tuesday. We plan to start the award presentations at 6pm, right before the start of round 5 of the TNM.

IM John Donaldson

Christopher Yoo has also agreed to join the broadcast as guest commentator that evening along with FM Paul Whitehead and FM Jim Eade, who will also be in attendance. It will be a terrific evening, and surely an entertaining broadcast. 

IM Christopher Yoo

Neil Falconer was a former Mechanics' Institute Trustee, Board President, and was influential in preserving the chess room as a part of the Mechanics' Institute. He was profoundly influential in promoting and supporting chess at the Mechanics' Institute, and he started this award in 1999, benefitting many top players of the future, including Sam Shankland, Daniel Naroditsky and many others.

Brilliancy Prize Reminder

We received many responses to the artile about brilliancy prizes, something that was a very common thing when I played competitive chess many years ago. We have thus decided to offer 2 monthly brilliancy prizes, and these can be games from any event in that month provided that it be a rated event and that there is a complete notation of the game. These prizes will come in the form of choice of book from our in office chess library and we will publish the games in our newsletter with annotations by GM Nick de Firmian. 

If you would like to submit a game for consideration, please turn in the scoresheet to us and mark "brilliancy" on top of the coresheet, that way we know it is submitted for consideration. Games from any rated tournament at Mechanics' in January will count for the January prize. We will also be making reminder announcements at upcoming events.

We hope this adds a fun element to playing games, and encourages bold and exciting action. Good luck!

Wednesday Night Blitz Report

Chess Titles - What to do with them?
Tournament Director's Corner
by Dr. Judit Sztaray

Many players are proud of their achieved chess titles, whether it’s norm based or not. As they should be!

As an organizer, it’s an interesting topic and decision to make: what titles to display in the tournament standings, and what titles we should omit?
There are some obvious ones of course: GM, WGM, IM, WIM – these are hard earned, norm-based, international titles that absolutely should always be displayed! I think we are all on the same page on this one.

Then there are two groups: the international, FIDE titles and the national, USCF titles. Both categories are not norm-based, but rating based titles, meaning if a player achieves a certain rating, the title automatically awarded him/her.

FIDE: Fide Master (FM) – min FIDE 2300, Candidate Master (CM) – min FIDE 2200, Women Fide Master (WFM), Women Candidate Master (WCM).

USCF: Senior Master (SM) – min USCF 2400, Life Master (OLM) – min USCF 2200, National Master/Master (NM) – min USCF 2200, Candidate Master (CM) – min USCF 2000.

The confusing title, as you can all probably see, is the CM title. If a player is listed as CM, it can mean two different things, as it’s used both in the FIDE and in the USCF categories, with very different criteria.

The big question is: should an organizer display these titles? and if the tournament begin USCF only, or both USCF and FIDE rated should change the answer to the first question at all?
I’ve posted this question to my fellow organizers across the country: and the main consensus is mostly that only those titles should be displayed that a player receives a certificate. Which is, to the best of my knowledge, for USCF is LM, SM, NM and for FIDE is GM, WGM, IM, WGM, FM.
We could also go with the only norm based titles of course, which is the official stand for the FIDE rated tournaments across the US and around the world.
From a parent/coach/player’s perspective however, every single title is an important achievement. So why leave it off? Does it hurt others if we display the titles?

What do you think? What shall we do here at Mechanics’? Any opinions or suggestions, email us to!

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be3 e6 7.f3 h5!? Here? I knew this is the big thing in the 6.h3 e5 7.Nde2 line, and 6.Be3 e5 7. Nb3 Be6 8.f3 h5 is a major line (when 9.Nd5 is the big thing in the big thing -- obviously not happening here!) 8.Qd2 Be7 9.0-0-0 b5 10.a3 Bb7 11.Kb1 Nbd7 Black's ounce of prevention is certainly looking worth it - White has trouble getting anything going. On the other hand, Black is now a bit loathe to castle. 12.Bd3 Rc8 13.h3 d5 [13...h4!?] 14.exd5 Nxd5 15.Nxd5 Bxd5 16.g4?!

[44...Rd2+ 45.Ke4 Re6+ 46.Kf3 (46.Kf5 Ra2) 46...Rh2 The only progress I'm making is on my clock towards 0:00:00. (I had 8 minutes to his 14).] 45.g5 Kg6 46.gxf6 Kxf6 47.c5 Re2 48.f5!?

37.a4? [37.h4!; and 37.g5! are both winning.

A confusion inducement: 16.Bxg6?? [16.hxg3+-] 16...Nxe2+ 17.Kf2 Nxc1 [17...Nxd4! is best (although all those captures win); 17...fxg6; 17...Bxd4+; 17...hxg6; 17...Rfe8] 18.Raxc1 Bxd4+ [18...hxg6 19.gxh3 Rfe8] 19.cxd4 Bxg2 20.Bxh7+ Kxh7 21.Kxg2 Black is still winning, although it could take a lot of work. 21...Rfe8 22.Kg3 Re2 23.Rf2 Rae8 24.b4 R8e6 25.Rxe2 Rxe2 26.a4 Rb2 27.b5 cxb5 28.Rc5 bxa4 29.Rxd5 [29.Ra5] 29...b5 30.Rd7 a3 31.Rxa7 b4 32.d5 Rd2 [32...a2 33.d6 Rd2] 33.Ra4
