Tuesday Night Marathon Round One Report

by Abel Talamantez

The Tuesday Night Marathon has returned to its seven-round, three-section format with 66 players. While the limited BART service, with trains not yet running past 9pm PT, is keeping some folks away for the time being, things are returning to normal. We have an increased turnout from our last TNM, and we look forward to regular public commuting options returning to full strength soon, helping facilitate more players joining us at the Mechanics' Institute building for chess once again.

In the top section, board 1 featured a battle of seasoned Mechanics' Institute veterans IM Elliott Winslow and Kristian Clemens. The game went long, and it appeared as if Clemens was going to hold the position in an enedgame with rook, knight, and pawns. However, a miscalculation led to a trading of material with Winslow getting the opposition in a king and pawn endgame to seal the win. A tough break for Kristian in an otherwise very well played game. Also with first round wins were NM Siddharth Arun, NM Christophe Bambou, Abhi Penagalapati, and Chelsea Zhou. Chelsea received a full point bye and would be paired with Juan Cendejas in an extra rated game, which was beautifully played by Juan. He responded to Chelsea's Sicilian with 2 b4!? He got the win, showing even the DGT technical manager extraordinaire still has solid game left in his tank.

In the under 2000 section, nine players go into week 2 with one point. The standout in this round was Albert Starr, who played very well in his upset of Luiz Uribe. Also among the point scorers were Mechanics' regulars Marty Cortinas rising youth Kevin Sun, who upset Glenn Kaplan. In the under 1600 section, 13 players are with one point. Among them are Valerie Jade and David Olson, as well as the up and comin young players Sebby Suarez, Andrew Ballantyne, and Issac Sterling. With 7 rounds of play, there is still ample opportunity for big moves in the standings. Also a big shoutout to Tobias Rex, who came back from a lost position against Sammy Agdamag to win the game. 

It was a fun atmosphere at the chess club, as we had the Annex open for post game analysis and skittles. It was great to see players analyzing their games after and play recreational chess once again in that room.

1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.f3!? The Blackmar-Diemer Gambit (where Black is "committed" to ...c6). 4...exf3 5.Nxf3 Bg4 6.Bc4 e6 7.0-0 Nf6 8.Be3 This move is a little slow for a gambit line. It would be a good move in a normal game, but here White has something to prove for the pawn. 8...Bd6 9.h3 Bh5 10.Bg5 Be7 11.g4 Bg6 12.Ne5 Bxc2?!

Double attack! 17...Nxd6 but also 17...Nc3 and 18...Nxe2+ (16...Bb7 17.Bf4 is still a solid advantage for White,with both bishops and pretty good pawns in the center.) 17.Bb4 (17.Be5 Nc3 18.Qe1 Nxe2+ 19.Qxe2 Bb7 20.Qd1 Qc8! readies removing both minor pieces with a strong major piece game, what with White's weak pawns.) 17...a5 18.Qc2 Bb7 19.Ba3 Ng5 20.Nxg5 Qxg5 21.d5 White still has both bishops but the pawns are somewhat compromised; Black isn't much worse.] 16.Nxc8 White cashes in for some material.

1.b4 Albert entertains with complications from move one! 1...d5 2.e3 e5 3.Bb2 Nd7 4.b5 Ngf6 5.c4 Bd6 6.cxd5 Nxd5 7.Nc3 White has gotten queenside play with his favorite opening. 7...N7f6 8.g3?!

22...Nd7? [22...dxc3 23.Nxc5 Qb4-+ Is an extra pawn and full control for Black] 23.Nxc5?

1.c4 Nf6 2.Nc3 g6 3.g3 Bg7 4.Bg2 0-0 5.e4 d6 6.Nge2 e5 7.0-0 Nc6 8.d3 The Botvinnik System of the English. 8...Ne8 9.h3 f5 10.exf5 gxf5 11.f4 Nf6 12.Be3 Qe8 13.Qd2 Qg6 14.Nd5 Nxd5 15.Bxd5+ Kh8 16.Kh2 Ne7 17.Bg2 c6 18.d4 e4 19.Nc3 Rg8 20.Rae1 Bf6 21.Bf2 d5 22.c5?! Black gets an edge now. It was better to make an open file on the queenside with 22. cxd5. 22...Be6 23.Nd1 Rae8 24.Ne3 Qg7 25.Rd1 Bf7-/+

26.Nxf5?? Black is better but this is just a blunder. 26...Nxf5 27.g4 Nh4?! [27...e3! or; 27...h5! would pour on the pressure] 28.Bxh4 Bxh4 29.g5 h6 30.Rg1 e3 [30...Bh5] 31.Qe2 Bf2 32.Bf3 The best practical try. 32...Bxg1+ 33.Rxg1 hxg5 34.Qd3 Qf6 35.f5 Qh6 36.Rg3 Qh4 [36...g4!] 37.Bg4 Bh5 38.Kg2?! Bxg4 [38...e2] 39.hxg4 Kg7 [39...e2 Stockfish is already finding mate in 7 for Black...] 40.f6+ Kf7! 41.Qb3

41...Rh8?? Almost anything else just wins for Black, being a whole rook up. [41...e2! (well, the fastest mate); 41...b5; 41...b6; 41...Qxg3+ 42.Kxg3 e2] 42.Qxb7+ Amazingly Black is lost now. It is mate in 4 no matter what. 42...Ke6 43.Rxe3+ Kxf6 44.Rf3+ Kg6 45.Qf7+ Black resignes as 46. Rf6 will be mate. A tragic turnaround for Sam and a lucky escape for T. Rex 1-0

New Thursday Night Marathon Rounds 7&8 Report

by Abel Talamantez 

Broadcast setup from the Mechanics' Institute

The final two rounds of the Thursday Night Marathon produced the matchup everyone had been waiting for - the matchup in round 7 of the two GM's Gadir Guseinov and Alex Lenderman again showed that GM Guseinov is a standard of play above many. He put Lenderman in a very tough position right away, and although Lenderman found the right moves to continue on, the pressure eventually became insurmountable, with Guseinov winning material and the game. Guseinov would go on to defeat Austin Mei in the final round in a very interesting game to win the Thursday Night Marathon with a score of 7.5/8. IM Bala Chandra Dhulipalla defeated IM Elliott winslow in round 7 and then survived a great game played by Cailen Melville in round 8 to get a draw in a losing position. It was still enough for Dhulipalla to finish with 6.5/8 and clear 2nd place.

GM Guseinov and GM Lenderman doing battle with commentary by GM Nick de Firmian, FM Paul Whitehead and Chess Director Abel Talamantez

Perhaps the game of the round was the matchup in round 8 between FM Max Gedajlovic and GM Alex Lenderman. Max fought bravely and aggressively, obtaining an advantage positionally. After reaching the middle game in a worse position, Lenderman offered a draw which Gedajlovic, after some thinking, declined. He showed the mettle of a player looking to go next level in pressing on in a winning position despite the opposition. It is always a gamble, as the lower rated player is trying to maintain an advantage and fighting against the calculating abilities and expeirence of a seasoned GM. Lenderman pressed on, finding opportunities to complicate the position, and after putting Gedajlovic in time pressure, created enough chaos in the position to get the win desite being the exchange down for much of the endgame. It was a great game to watch, and we will have annotations for the final rounds of the ThNM in the next newsletter. Kudos to Max for going for the win, but kudos as well to Lenderman for staying cool when things got hot. 

Special shoutout to Mechanics' regulars Cailen Melville and Jonah Busch for an outstanding performance in this event, as well as Marina Xiao. She will be a force to bre reckoned with in the coming years.

Finishing Tactics from the World Championship Matches 20: Smyslov – Botvinnik 1958

After losing the title a year earlier, Botvinnik exercised his right to a rematch (under FIDE rules at the time) and came out slugging – he won the first three games and ultimately the contest by the score of +7 -5 =11. 

The players were not at their best: both came down with the flu, and both were prone to strange mistakes and lapses:

Smyslov – Botvinnik, 3rd Match Game 1958.  

Here the World Champion made the elementary blunder 1.Ne5? losing 2 pieces for a rook and ultimately the game after the simple 1…Rxc3! 2.cxb7+ Kxb7 3.Rxc3 Bxe5.

Even more surprising was what happened here:

Smyslov – Botvinnik, 15th Match Game 1958.

Black was enjoying his position so much (he’s very close to winning) he “forgot” about the clock and lost on time!


1. Botvinnik – Smyslov, 2nd Match Game 1958.

White moves.  Win a little something.


2. Smyslov – Botvinnik, 5th Match Game 1958.

White moves.  Surprise!


3. Smyslov – Botvinnik, 9th Match Game 1958.

Black moves.  What’s your defensive task?


4. Botvinnik – Smyslov, 14th Match Game 1958.

White moves.  Not difficult, but be accurate.

GM Nick de Firmian's Column

The Old Man and the Chessboard

In Hemingway’s famous novel about an aging fisherman, the protagonist battles for days to reel in a great marlin. Ultimately he wins the battle against the marlin, but fails when encountering too many sharks that eat the marlin tied to his boat and steal his hard-earned victory.

The Grand Croatian Chess Tour saw the return of the great Garry Kasparov to the chess board. He too ran into a bunch of sharks who stole all his points, and in eighteen rounds of blitz chess against the young top players of today Kasparov scored only two and a half points. This disappointing showing is usually done by an amateur who gets to play with the pros, and that player is often labeled the “fish” of the tournament. It was painful to see how a great champion can fall.

“The old get old and the young get stronger” sang Jim Morrison. So perhaps we must resign ourselves to playing worse chess as we age. Here we have some good news for those who wish to defy the march of time. Second place in this same tournament went not to one of the young sharks, but to 51 year old Vishy Anand. Anand is of course a former world champion and was a rival to Kasparov in the 1990’s. It was inspiring to see him vanquishing players half his age. The rest of us may take solace that excellence at chess isn’t just about age, but about staying motivated and dedicated to the game.

(1) GM Kasparov,Garry - GM Vachier-Lagrave,Maxim [A30]
Grand Chess Tour Croatia, 11.07.2021

This game was played in the second to last round, with MVL in first place. Despite having a terrible tournament Kasparov is determined to show the leader what championship chess is. 1.Nf3 c5 2.c4 Nf6 3.g3 b6 4.Bg2 Bb7 5.Nc3 g6 6.0-0 Bg7 7.d4 cxd4 8.Nxd4 Bxg2 9.Kxg2 This hedgehog position out of an English Opening is just a tad better for White. 9...Qc8 10.b3 Qb7+ 11.f3 d5 MVL makes the center break instead of sitting back on the first three ranks as most Hedgehog players do. This equalizes space in the center, but Black lags in development in the resulting open position. 12.cxd5 Nxd5 13.Nxd5 Qxd5 14.Be3 Nc6 15.Nxc6! Qxc6 16.Rc1

The pawn structure is symmetrical but White is first to sieze the open files. It's hard to make good use of this edge yet Kasparov does so. 16...Qe6 17.Qd3 0-0 18.Rfd1 h5 [18...Rfd8?? 19.Qxd8+ Rxd8 20.Rxd8+ Bf8 21.Bh6 leads to a quick mate] 19.Bf2 Bf6 20.Qc4 Qxc4 21.Rxc4 Rfd8 22.Rxd8+ Rxd8 23.Rc7 a5? Black could have tried a more active defense with [23...Rd2 24.Rxa7 Rxe2 25.Kf1 Rc2 26.Bxb6 Rxh2] 24.Be3! stopping infiltration of the black rook 24...Rd6 25.Rb7 Now White will win a pawn. 25...Bd4 26.Bxd4 Rxd4 27.Kf2 Accurate play. Now if 27...Rd2 28. a4 defends the white pawns and attacks two of the black ones. 27...a4 28.Rxb6 Rd2 29.bxa4 Rxa2
So Kasparov is a pawn ahead in a rook ending against the leader. In his championship days he would have converted this advantage, but now he runs into trouble against a stout defense. 30.Rb4?! [30.Ra6 Would be a better placement for the rook since it could help the a-pawn advance a couple of squares. Defending the pawn from b4 means the white king must come over to help before it marches further.] 30...Ra3!
This is an instructive move. MVL cuts off the path of the white king to come to the a-pawn. 31.h4 Kg7 32.Ke1 Ra2! I hope you guessed this move. It is the same reason as on move 30, to keep the white king out of the queenside battle. If the white king moves the queenside then the white e-pawn is undefended. 33.Kf2 Ra3 34.Re4 Kf6 35.Rf4+?! [Now is the time to try 35.Ke1! Ra2 36.Kd1 and head to the queenside] 35...Ke6 36.g4?! deciding to advance on the kindside, but this gives white poor pawn structure. 36...hxg4 37.fxg4 f6 38.h5?! This last impatient move throws away the remaining winning chances. 38. e3 would have cut off the black rook on the third rank. 38...gxh5 39.gxh5 Rh3 40.a5
This positon shows a very interesting point in the struggle, and helps explain the great result of MVL and bad result of his opponent. White has been pressing to win for 30 moves but now loses the dangerous a-pawn. (The h-pawn is closer to the black king and thus not such a danger to queen,) The position suddenly goes to even material and White is in danger of losing a second pawn when the black king and rook surround it. Kasparov spent all his time trying to win, yet suddenly he must defend. 40...Ra3! 41.h6 Rxa5 42.Rh4 Ra8 Just in time the black rook come back to stop the h-pawn. Kasparov was down to 7 seconds on the clock. 43.Ke3 Ke5
And here Kasparov lost on time. He can make a draw even when he loses the h-pawn, but his form was so bad that he couldn't make the good moves in time. A horrible and undeserved loss, but that's what happens. The winning player makes use of all the chances and the loser can't handle the "unfair" changes of fate. 0-1

(2) GM Anand,Vishy - GM Nepomniachtchi,Ian [B46]
Grand Chess Tour Croatia, 11.07.2021

Here Anand meets the current challenger to the chess throne, Nepomniachtchi, who will have the title match with Magnus in November. 1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nc6 5.Nc3 a6 6.Nxc6 bxc6 7.Qf3 d5 8.Qg3 f5!? As he often does, Nepo chooses an imbalanced position. 9.exf5 exf5 10.Bf4 Nf6 11.Be2 Ra7 12.0-0 Kf7 13.Rad1 h6 14.Be5 g5 15.Rfe1 Bg7 16.Bf1 Re7 17.Bd4 Rhe8

Despite the unorthodox treatment of this Sicilian Black has all the pieces out and equal chances. 18.Rxe7+ Qxe7 19.Qd3 f4 20.a3 a5 21.Na4 Bg4 22.f3 Bd7 23.Nc5 Bc8 24.Qc3 g4 25.Nd3 gxf3 26.gxf3 Nd7 playing for the attack on the g-file 27.Bxg7 Rg8? The pin gets the bishop back, but Black had to first play [27...Qe3+ 28.Nf2 then 28...Rg8] 28.Kh1 Rxg7 29.Qxc6! This looks risky but it's good. 29...Qg5 30.Bh3 Carefully defending against the mating threats, which is especially hard to do in blitz. 30...Nb6
31.Bg4! This makes use of the forking defense against the double capture on g4. White is now well ahead. 31...Bxg4 32.fxg4 Kg8 33.Nf2 Rg6 34.Qe8+ Kh7 35.Re1 Rg7 36.b3 Nd7 37.Qe6 Nf6 38.Re5 Qg6 39.Qf5 Rc7 40.Qxf4 Rxc2 41.Re7+ Kh8 42.Re6 Kg7 43.h3 Qf7

44.Qe5! leaving the white knight hanging allows Anand to press the attack. 44...Qf8 45.Re7+ Kg8 46.Qe6+ Kh8 47.Rf7 Qxf7 48.Qxf7 Rxf2 The white queen is too strong for the black rook and knight. Vishy wraps it up efficiently. 49.Kg1 Rf4 50.Qg6 Rf3 51.Qxh6+ Kg8 52.Qg6+ Kf8 53.Kg2 1-0

Solutions to FM Paul Whitehead's Column

1. Botvinnik – Smyslov, 2nd Match Game 1958.

1.Nc6! was a cute little move, and white won a pawn after 1…Bxc6 2.Qxc4+ d5 3.Qxc6. Black was faced with an impossible defensive task (3…Rxb4 4.Nxd5 wins) and succumbed quickly: 3…Rd8 4.Qb6 Qe7 5.Qd4 Qd6 6.Rfe1 Rfe8 7.Rxe5 Rxe5 8.b5 Ne6 9.Qa7 d4 10.Ne4! 1-0. If 10…Rxe4 11.Qa8+.


2. Smyslov – Botvinnik, 5th Match Game 1958.

1.Kd3!! 1-0. Threat: 2.b4# which black can only delay, but not stop.


3. Smyslov – Botvinnik, 9th Match Game 1958.

1…g5! Hiding the king behind the attacking h-pawn saves the day.  The game petered out to a draw after 2.Bxg5 Qd6 3.Rh4 Nf6 21.Bxf6 Qxf6 22.Rxg4+ Kh8 23.Kb1 Rg8 24.Rb4 a5 25.Rb6 Bxc3 26.bxc3 Rab8 27.Rxb8 Rxb8+ 28.Ka1 Rg8 29.Qe3 Rg4 30.a3 Re4 31.Qd3 Qe5 32.Kb2 Re3 33.Qd4 Qxd4 34.cxd4

Kg7 35.Rg1+ Kf7 36.h6 Rh3 37.Rg7+ Kf6 38.Rh7 Rh4 39.Kc3 Rh3+ 40.Kb2 Rh4 1/2-1/2


4. Botvinnik – Smyslov, 14th Match Game 1958.

1.f4! 1-0. But not 1.c8=Q? which only leads to a draw after 1…Rxc8 2.Kxc8 Kxf2. After 1.f4 white can simply push his f-pawn and sacrifice his rook if need be for the h-pawn.
