2020 Max Wilkerson Memorial TNM Round 2!
Top Players Hold Court in Round 2, "A" Player Nicholas Weng Making Moves In Championship Section of TNM
Round 2 of the TNM concluded, and the top players mostly held on to victory in the championship section to set up a very competitive round 3. FM Josiah Stearman defeated the always dangerous NM Aleksandr Ivanov and FM Kyron Griffith defeated NM Michael Walder. IM Elliott Winslow fought back to beat Ethan Boldi and NM Rui Yang Yan defeated Steve Gaffagan. The biggest surprise was 12 year old Nicholas Weng (1854), who last week defeated expert Jason Childress and this week got a big win against WFM Natalya Tsodikova.
In this game, Tsodikova (black) lost on time, and was clearly losing the game. However, right before her time expired, she arrived to this position with black to move:
White is threateing mate in 1 with Rg7#, and with seconds left, she missed a beautiful move that draws on the spot with Rh5+!! Black sacrifices the rook and white must capture it. In doing so, a stalemate is on the board, resulting in a draw. Too bad she missed this manueuver, which goes to show that even the best players miss tactical shots when the seconds are ticking on the clock.
The top 2 boards do battle: Stearman - Ivanov and Griffith - Walder
In the A/B section, only 3 players are at 2/2 and there are 28 players in the section! On top are Bruce Ricard, Robert Drane, and Gagik Babayan. However, there are still 5 rounds to go, and plenty of strong players sit at 1.5/2 including the always dangerous Erika Malykin, Rudolph Breedt, Renjish Abraham, Anthony Acosta, Adam Mercado, Nicholas Latourette, and Michael Baer.

In the under 1600 section, 9 people are at the top with 2/2 in a 49-player section. Thos eplayers with perfect scores are Ivan Rothman, Jahaan Ansari, Ilia Gimelfarb, Albert Starr, Valerie Jade, Eitan Neugut, Jerry Simpkins, Charles James, and Julian Sachs-Weintraub.
Tune in next week for round 3 coverage. We will have very special guest commentator IM Kostya Kavutskiy in with FM Paul Whitehead. Kostya is a professional player, coach and streamer who also writes extensively for USChess and last year was the commentator for the stream at the US Open.

Tournament Director's Corner
Proper Castling
A player informed me after a game had ended that early on in the game, his opponent (white) had castled by first touching the rook, moving it to f1, then releasing the rook. Then the player picked up the king and moved it to g1 and completed the castling maneuver. The question I was asked was if this is an illegal move?
The USCF rule book states:
10I2. Rook touched first. If a player intending to castle touches the rook first, castling is not allowed and the player must move the rook as required by rule 10B.
The king must be moved first, then the rook. If the above scenario had happened, the player attempting to castle would have had to leave the rook on f1 and that would have been the completed move, thus losing the right to castle and leaving the king at e1. Additionally, the player making the claim would get an additional two minutes added to their time per the standard penalty:
1C2a. Standard penalty. Except where specifically noted in the rules, the standard penalty assessed by the director is to add two minutes to the remaining time of the opponent of the player not following the rules of chess.
A very important point to add here is that it is important for players to come see a TD whenever there is a question of a rule violation in a game. It has been my exprience that if a player inquires about a rule or calls a TD to enforce a rule, it is very rarely frowned upon by an opponent, and often times, ends up being a learning experience for all. As tournament directors, we can only intervene and help if something is brought to our attention, most things cannot be remedied after the game is over. So please be proactive and advocate for yourself and the rules of chess, please see a TD whenever something questionable happens, and you may always pause the clock if you legitimately need an Arbiter.
Brilliancy Prize Update
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!

Famous Chess Games You Should Know.
The “Miniature” - World Champion Examples, Part 2.
By FM Paul Whitehead
The first move is valuable! White wins all 5 of these games. As usual the common themes apply: rapid development and early mistakes.
Not to mention near-divine inspiration.
Petrosian is here twice, as winner and loser. Last week in this column we saw Lasker and Fischer crushed. Even the greats fall, though it will take exceptional play and an exceptional player to take the point from them. And maybe some luck and good fortune.
My favorite game here is the lesser-known: with all this chess, good and bad, Mikhail Tal’s cheeky win in a simultaneous exhibition is surely other-worldly!
Next week: Fischer to Carlsen.
(1) Mikhail Botvinnik - Lajos Portisch [A22]
Monte Carlo Monte Carlo MNC, 1968
Botvinnik became World Champion in 1948, losing the crown and winning it back in rematches against Smyslov and Tal until Petrosian removed it permanently in 1963. Not to mention a tied match with Bronstein in 1951. This brilliancy was played in the twilight years of Botvinnik's career, his last tournament game coming in 1970. 1.c4 e5 2.Nc3 Nf6 3.g3 d5 4.cxd5 Nxd5 5.Bg2 Be6
(2) Vasily Smyslov - Cenek Kottnauer [B84]
Groningen Groningen NED, 1946
Over the course of three World Championship matches with Botvinnik, Smyslov won 18 games to Botvinnik's 17 (with 34 draws). Yet he only held the title for 1 year after winning the title in 1957. 1.e4 This is a game from Smyslov's youth. In later years he rarely opened with 1.e4. 1...c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be2
(3) Mikhail Tal - Sviridov [B75]
Simul Stuttgart FRG, 1969
This charming game was played in a simultaneous exhibition. Tal could never resist a beautiful idea, move, or combination. And he created many. 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6
(4) Tigran Petrosian - Ludek Pachman [A07]
Bled Bled YUG, 1961
Petrosian took the title from Botvinnik in 1963 and then warded off Spassky once before losing the title in 1969. Known as perhaps the greatest defensive player ever, Petrosian was also a feared blitz player and a master tactician. 1.Nf3 c5 2.g3 Nc6 3.Bg2 g6 4.0-0 Bg7 5.d3 e6 6.e4
(5) Boris Spassky - Tigran Petrosian [B94]
Petrosian - Spassky World Championship Moscow URS, 1969
An attacking masterpiece from the 1969 World Championship match. 1.e4 c5 Petrosian played the Sicilian more frequently than one would have thought, although the French and Caro-Kann better suited his style. 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5
Black resigns. If 24...hxg5 25.Qxh5+ Kg8 26.Qf7+ Kh8 27.Rf3. And all other tries lose as well, as you can find out for yourself. A single-minded attack! 1-0

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Qe2!? Just one of the "Odds & Ends" moves, which Kyron has shown some interest in. Vigorito (in his "Playing the Najdorf" 2020 book) notes that this move does have the highest scoring percentage! This game just made it worse. (Note: I prefer the Najdorf.) Essentially White can play (and has played) anything here: [6.Nb3 Kyron played this last year.; 6.Qf3; 6.Qd3; 6.a3; 6.Rg1; 6.Bd3; 6.-- But I think Black is still more likely to see one of these:; 6.Bg5; 6.Be2; 6.Be3; 6.Bc4; 6.f4; 6.a4; 6.h3; 6.-- Did I leave anyone out? I'm pretty sure I did. So the question is: is the Najdorf so good that White has to try something different all the time to look further and further afield for anything? Or is it so **bad** that White can play almost anything?] 6...e5 7.Nf5 d5! 8.Bg5 d4 9.0-0-0
