FM Stearman Takes Control of Championship Section of TNM
On Board 1, FM Josiah Stearman was apparently in full preparation in his match against CM Sriram Krishnakumar
The 5th round of the Steve Brandwein TNM created some separation at the top of the leaderboards, with two of the hottest young players facing each other on the top board of the championship section. When the smoke cleared, it was FM Josiah Stearman with the black pieces that came out on top over CM Sriram Krishnakumar. Stearman delivered a beautiful final tactical shot worthy of any puzzle book, and the game and its ending can be found at the end of this newsletter. NM Eric Li had a strong result against NM Tenzing Shaw to continue playing solidly in the top section. FM Kyron Griffith also moved up the leaderboard with a win against Sergey Ostrovsky. NM Jeevan Karamsetty also returns after a bye week next week to battle it out. It appears these three players pose the biggest challenge to Stearman, who is looking in top form in thos tournament.
In the A/B section, Mansoor Mohammed survived a scare and had a bit of luck in pulling out the win against Rafik Robeal. More is written about this game in a column below, but it was one of the more dramatic games of the ournament and it was all caught on live video. Mohammad is a perfect 5/5 so far. With 4/5, Robert Drane drew with Lex Huberts, setting up a potential board 9 matchup next week against Mohammed, since the other 4/5 score in the section is Teodoro Porlares, who already played Mohammad.
In the under 1600 section, Sterling Albury put a stop to the Jerry Simpkins train, defeating him on board 10. Albury is now the sole leader of the section at 5/5, with 4 players at 4/5, including Jerry Simpkins, Lucas Radaelli, John Bielic and Jahaan Ansari.

Tournament Director's Corner
The TNM produces great fodder for TD's, always keeping us on our toes and providing situational content that is very instructive for tournament players. We had another such occurrence in round 5, involving the final game of the day on broadcast board 9 between section leaders Rafik Robeal and Mansoor Mohammed.
The drama was captured on our live broadcast, here is the link:
https://www.youtube.com/watch?v=CyWTtmXvAcw&t=10990s
Coverage of the end began at the 3:05:00 mark of the video. With both players racing against time, Mohammed (black) was trying to make progress in the game. At the 3:09:00 mark, that is when the real fireworks began. He had a rook and 4 pawns against Robeal's Bishop and 6 pawns. Paul, Judit and I were following the game on the broadcast, when suddenly we noticed the players discussing something over the board at the 3:10:15 mark, which is when we went into the playing area. When I went to the board, play had resumed and then an illegal move was made at the 3:10:35 mark. At that point, since white made the illegal move, black was awarded two additional minutes of time, and I replaced the clock on the board with a DGT North American clock as it was faster for me to immediately set the time so play could resume. At the point of play resuming, black now had 2:27 left, and white had 1 second. In the play that followed, white blundered into mate, in what was otherwise a drawn game.
What made this situation instructive were two things. First, there appeared to be a claim by white that the game should have been drawn be repetition. However, notation had stopped already since players were under 5 minutes and blitzing moves, so a claim cannot be made by the scoresheet. Players always have the right to stop the clock and get an arbiter to supervise a game where they suspect that a draw claim may be made by 50 moves or possible repetition. In fact, Robeal's time would have expired and he would have lost the match had not Mohammed stopped the clock for him with one second left to claim an illegal move! Second, players should be aware that stopping the clock to get an arbiter to make a claim or supervise play in their specific game is always something they can do. We have seen this in other games during the TNM in which I was called to count moves.
Always make any offers of a draw clearly and wait for an agreement. They should be done on the time of the player offering the draw. They should make their move, offer the draw, and THEN hit the clock. Robeal appeared to have made a draw claim or offer of a draw, it was clearly not scknoledged or accepted by Mohammed, but Robeal did not hit his clock after the offer, or pause the clock to get a TD. It almost cost him the game on time had Mohammed not stopped the clock for him, not realizing there was 1 second left.
An exciting, dramatic, and very instructive situation at round 5 of the 2019 Brandwein TNM.

Labor of Love at CalChess State Championship
annotated game by Michael Walder
The CalChess Labor Day State Championship concluded in Santa Clara this past weekend, and Mechanics' regular Michael Walder scored 5/6 to win outright the expert section of the tournament. He took home the biggest cash prize of the tournament, since there was a 5-way tie for first in the open section! Below is one of his games from that tournament, annotated by the champion himself.

Addison's novelty. While it combines the dual threats of targeting the pawn on h6 and the queen invasion on b6, it takes pressure off of f7.

How blind people play chess
By Lucas Radaelli
The one big thing that attracts me in chess is the possibility of blind people to play with sighted people, deaf people, even aliens, if they were here already here. It is the only sport I believe the competion is fair and equal for all. Chess is a game that exists on the board, but really happens in the mind. Then, a natural question arises: how do blind people play chess?
We use a special chess set, where the pieces can be touched without leaving their square. This is possible because each square has a small hole, and each piece can be fixed in the hole thanks to a small nail under it. Talking about squares, black ones are raised compared to the white ones, so also by touch, it is possible to immediately distinguish them. Finally, black pieces have a pin on the top, where white pieces do not.
When playing a blind person, two boards will be used. The regular one and the special set. This is to make sure that the blind person can explore its own board without disturbing the other player, which may want to look at the board at all times. A piece is considered "touched" in this case when the blind player removes the piece out of its hole, by raising the nail under the piece from the board. Note from editor, Judit Sztaray: It is important that at this point it's emphasized that BOTH players are playing under USCF rules.
Moves are communicated using algebraic notation. When one of the players say a move, the other is responsible for making the move in its own board and annotating. So, for example, if I have the black pieces and my opponent says: e4. He would move e4 in his own board, I would move e4 on my special set, and the game would continue. My move I would say my move, he would move the piece for me on his board as well.
In tournaments only for the blind, we normally use special letter names to avoid any ambiguity. So, instead of using regular letter names, we use a = ana, b = bela, c = caesar, d = david, e = eco, f = felix, g = gustav and h = hector. This is not required, just makes easier the process of communicating moves. Example: eco 4, knight felix 3, queen david 5.
Blind people annotate either using braille or a voice recorder. Voice recorders are more portable then braille writing equipement, so they are preferable. Annotating is important. If, for some reason, the two positions on the players's board differ at some point, they shall be returned to a point where the two scores match. Note from editor, Judit Sztaray: It's not only important, but it's also the USCF rule to notate your game if you have more than 5 minutes on your clock. With the voice recorder, Lucas is following this USCF rule, and not getting any special, preferencial statement.

2. Cartoons.
I like to have a good laugh, and chess provides much fertile ground for humor. The cartoon panel is like the snappy mate in three shown by Tony in the club; or maybe just a respite from the spite-check before resignation…
Addams is as gentle as his snow; Steinberg burns with his toaster.
Direct and surreal, the cartoon is a Zen slap to the funny bone, and a powerful reminder:
It’s only a game.

GM Nick de Firmian's Column
Magnificent Magnus #5 – Defense 2: The Counterpunch
We return to that topic of defense, where things are not going how you like it and you must attend to your opponent’s evil plans to ruin your position or just checkmate you with a nice finishing combination. It is more fun to be the aggressor and dictate the flow of the game, trying out your ideas of how to break through. When you are under attack or down material you have no choice but to carefully check through the possible plans your opponent will throw at you and do your best to stop them from coming to reality. All this is very necessary and good, but in defense it’s also very useful (and fun) to sometimes throw in a counterpunch. Not only does that do damage to your opponent, it also keeps him/her honest so that the attack against you doesn’t come with full force. I refer one more time to Mohammed Ali, this time when he was defending on the ropes against George Foreman. Foreman was attacking furiously while Ali was in a defensive posture on the ropes. Yet Ali’s jab and counterpunches took enough of Foreman’s attention that he could not push through with a winning barrage. After his own attacks sapped Foreman’s energy Ali finished him off.
Magnus seems to defend less than any other chess player as his positions are generally very pleasant. Once in a while it goes wrong for him and he must suffer like the rest of us. There are also the games when his opponent is like George Forman and comes right at him with everything – Magnus may have a good position but needs to defend his king. We give two examples below of Magnus defending. In the first game he screws up and blunders a piece, when he has to scramble and make use of whatever opportunities present themselves to save the game. In the second example Magnus has a good situation with his attackt and material, but finds himself in dire straights to stave off checkmate. Both of these games see Magnus ready to lash out when given a chance. He uses the counterpunch as effectively as anyone in the game.
(1) Magnus Carlsen (2834) - Gawain Jones (2640) [B76]
Tata Steel Masters Wijk aan Zee NED (8), 21.01.2018
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.Be3 Bg7 7.f3 Nc6 8.Qd2 0-0 9.0-0-0
 |
We have an exciting Yugoslav Attack in the Dragon Variation. Jones is an expert in the Dragon, having written two books on it. Usually Magnus and his team are well prepared, but this day the opening goes a bit wrong. 9...d5 10.Qe1!? e5 11.Nxc6 bxc6 12.exd5 Nxd5 13.Bc4 Be6 14.Kb1 Re8 15.Ne4 f5 16.Ng5 Bc8!
 |
Jones retreats the bishop to avoid be traded for the white knight. Now 17. h4 would be a reasonable move with about even chances, but Magnus goes wrong. 17.g4?? f4!
 |
Magnus has just lost a piece! Both his bishop and knight are attacked so one will be lost. This is a real knockdown blow, and at grandmaster level usually a knockout blow. Yet Magnus steadies himself and plays on. 18.h4 fxe3 19.Qxe3 h6 20.Qc5 What to do when you are busted? One thing is to pretend you are not so that your opponent becomes a little worried. Did Magnus blunder or was it some Tal like sacrifice? Here Magnus starts to make a little trouble, threatening Qxc6 and Jones uses some clock. 20...Bb7 21.Ne4 Re6 22.h5 Qb6?
 |
Eager to trade queens and go into a piece up ending, Jones rushes with this move. If he had locked up the kingside with 22...g5 he would have kept a winning advantage. 23.g5! Now Jones realizes he should not trade queens do the the knight fork on c5. Meanwhile Magnus has been able to open the kingside. 23...hxg5?! 24.Qa3!
 |
Suddenly Magnus has full value for his lost piece. This positon is one Tal would have gladly played from the White side. The strange change of fortune seems to have rattled Jones. 24...Rb8 25.b3 Qd8? Magnus has been careful to keep a very solid postion, leaving Jones to worry which of his weakeness to defend. He underestimates the power of White's next move. 26.Qxa7!
 |
Magnus grabs another pawn, but the real power of the move is that the white queen is well placed at this strange outpost. 26...gxh5 27.Rxh5 Rg6 28.Rxg5! White now has a large advantage. The black queen must guard the rook on b8. 28...Rxg5 29.Nxg5 Qc8 30.Rg1 Ra8 31.Qb6 Ra6 32.Qc5 Qd7 33.Ne4 Kh8 34.Qf2 Qe7 35.Bxa6 Bxa6 36.Qh2+ Kg8 37.Qh6 Qa7?! 38.Qe6+ Kf8 39.Rg5 Ne3 40.Qd6+ Kf7 41.Nc5 Bc8
 |
42.Rxg7+ Jones resigned as 42....Kxg7 43. Qxe5+ picks up the knight on e3. Cool yet energetic play from Magnus after putting himself in a terrible situation. 1-0
(2) Magnus Carlsen (2834) - Li Chao (2750) [D70]
Qatar Masters Doha QAT (5.1), 24.12.2015
This is a game of violent attacks. Magnus does well on the attacking side, netting a huge material advantage. He then is left with the task of defending his king against an army of pieces that look to have the white monarch in a hopeless situation. 1.d4 Nf6 2.c4 g6 3.f3!? d5 4.cxd5 Nxd5 5.e4 Nb6 6.Nc3 Bg7 7.Be3 0-0 8.Qd2 Nc6
 |
The opening is an interesting Grunfeld where White has his usual pawn center and Black has piece pressure against d4 and queenside play. 9.0-0-0!? This unusal queenside castling makes for a super sharp game. 9...f5 10.e5 Nb4 11.Nh3 Qe8 12.Kb1 a5 13.Be2 c6 14.Rc1 Kh8?! 15.Ka1
 |
This king move by Magnus is helpful defensively as this is the best square to hide from the coming invasion of black pieces. Note how Li Chao's similar king move does not help against the white attack. 15...Be6 16.Nf4 Qf7 17.h4! This is a clever move for both attack and defense. It wastes no time for attack and defensively Magnus decides that he can live without the a-pawn. 17...Bxa2 18.h5 Kg8 19.hxg6 hxg6 20.g4 Bb3 21.Bd1 a4
 |
Both sides are breaking though to the enemy kings. 22.Qh2 Rfd8 23.Qh7+ Kf8
 |
24.d5! One should always remember to take care of the center as that has a big influence on the success of the wing attacks. White now threatens to take the knight on b6. 24...Nc4!? 25.Nxg6+ Ke8 26.e6
 |
26...a3! 27.exf7+ Kd7
 |
An amazing position. White's attack has been so successful that he has won a whole queen, yet he is in terrible danger. Black has two knights, two bishops one (or two) rooks and a deadly advanced pawn ready to deliver mate. The threat of axb2+ is horrific. White cannot take the a-pawn as 28. bxa3 Rxa3+ wins (one line is 29. Kb1 Ba2+ 30 Nxa2 Rb3+ 31. Bxb3 Na3 mate). Magnus keys in on the biggest trouble maker of the black army - the knight on c4. 28.Ne5+! Bxe5 29.Qxf5+ Kc7 30.Qxe5+!
 |
It is this move that takes the black knight away from c4. Black must take the queen. 30...Nxe5 31.Bxb3 axb2+ 32.Kxb2 Nbd3+ 33.Kb1 Nxc1 34.Rxc1 The black attack is over. White had to give back almost his entire material advantage, but is left with a winning postion due to his advanced pawn on f7. 34...Kc8 35.dxc6 bxc6 36.f4
 |
Li Chao resigned as he cannot take the pawn on g4 (Be6+) and the white minor pieces control the board. Heart stopping action! 1-0
