Mechanics' Fall Tuesday Night Marathon (TNM) 2012


Mechanics Chess Room Stairway

The Tuesday Night Marathon

"The Mechanics' Tuesday Night Marathon has a rich tradition that dates back at least 30 years. The idea of playing serious chess one night a week has appealed to a broad range of players from Senior Master to beginner, who find the time commitment fits their schedule quite comfortably. Today we think of eight rounds as the normal duration for a TNM, but that has not always been the case. In 1975 they played 12 rounds per tournament. Recently the Marathon switched to having sudden death for the second time control. It was probably the last tournament in the world to still feature adjourned games, the rest of the chess community having given up the practice years ago due to the rise in playing strength of computers. The Mechanics' still has several hundred adjourned move envelopes, which will no doubt become collector's items.
The TNM not only provides strong competition for players ranging in strength from Master to beginner, it's also very affordable with an entry fee of $40 for eight/nine USCF rated games. The Marathon is a perfect fit for those who can't commit an entire weekend to chess. No matter what your strength, the Tuesday Night Marathon might be the right tournament for you!"

During break between rounds, Mechanics, SF
The last post in 2012, I decided to write about Mechanics Fall TNM 2012 in which I just finished 6.5 ouf of 9 rounds couple weeks ago. I went undefeated and clear 4th place, which qualified me to won the expert section. Before I talk about Fall TNM 2012, there are so many unforgettable histories and experiences I played in TNMs that I want to share and review over the last 2 years. In 2009, the very first time I played in rated tournament in USA, which was the Fall TNM. It started my victory over 17 hundred player. I still remember that time I was super excited to win my first game in the tournament.  On top of that , I even drew against 19 hundred player and lost an expert. It was pretty amazing performance for me, who was unrated and hadn't played a chess for a long time ever since I graduated my high school in Mongolia, 2007. During the college years,  in University of Mongolia, unfortunately, I had no time for chess at all. Frankly, my victory over 17 hundred player in Mechanics was a huge influence to get me back to chess again.

Here is the one of my games I defeated a master.

In Summer TNM 2010, even though I got 4 out of 8 including some win over experts, I still gained about 100 rating points. 
Fall TNM 2010 was another successful one. I finished 5.5 out of 9 without playing my last round and picked up about 100 rating points to get my rating 1973. (I remember the reason I couldn't make was the same day and  the same time my final exam was scheduled. ). 
"National Master Peter Zavadsky, Experts Hayk Manvelyan, Oleg Shakhnazarov and Igor Traub and Class A player Uyanga Byambaa are tied for first after three rounds of the Fall Tuesday Night Marathon with perfect scores. Byambaa, a 20-year-old Mongolian student, has been particularly impressive with wins over Expert Steven Gaffagan and National Master Russell Wong the last two rounds. 
Peter Zavadsky, Christophe Bambou and Demetrius Goins share the lead in the Fall Tuesday Night Marathon with 4.5 points from 5 rounds. A large group of players are tied at 4 including 20-year-old Mongolian student Uyanga Byambaa of Oakland who has score 200 point or more upsets in three of her last four games."

In Winter TNM 2011, I had an outstanding result, 6 out of 8. In last round, on board 1,  I faced against IM Walter Shipman and game ended with unfortunate draw by losing my winning chances blundering a pawn in time pressure. It cost me to miss the opportunity to tied for first.



"International Master Walter Shipman, who turns 82 on April 18th, has clinched at least a tie for first in the 2011 Mechanics' Institute Winter Marathon after defeating top-seed NM Peter Zavadsky last night. Shipman leads with 6.5 from 7 with NM Robin Cunningham and rapidly improving Uyanga Byambaa tied for second with 5.5 points. As Shipman drew Cunningham in round 4 he will face Byambaa in the last round."/Mechanics' Institute Chess Club News 526/ http:/ /chessclub.org/news.php?n=526
IM Walter Shipman made history last night by becoming the oldest ever winner of the Mechanics' Institute's Tuesday Night Marathon series which dates back to the early 1970s. Shipman almost had company at the top. Leading by a point going into the last round he saw one of his pursuers - NM Robin Cunningham - win quickly and the other - Uyanga Byambaa - quickly obtain a promising position against him. The rapidly-improving 20-year-old Mongolian student hoped to repeat the earlier TNM triumph of her fellow countrywomen Batchimeg Tuvshintugs, and for much of the game against Shipman it looked certain she would be victorious, but the wily veteran saved a difficult rook ending to emerge alone with 7 points from 8 games. NM Cunningham was second with 6.5 followed by Byambaa (who picked up 79 points to raise her rating to 2051) and Expert Igor Traub.

In Spring TNM 2011, I started off incredibly 5 wins in a row but ended up tough fighting 3 loses.

"Uyanga  Byambaa  is leading the Spring Tuesday Night Marathon with a perfect score after 5 rounds. Presently rated Rated 2050 - up over 200 points in the last six months - the 20-year-old Mongolian student has defeated three strong Experts and drawn with a National Master in this event to date. Should she win Byambaa will become only the second women champion in the close to forty year history of the TNM series. Countrywomen Batchimeg Tuvshintugs, recent winner of the 2011 Mongolian Womens Championship, tied for first in the Fall 2006 and Winter 2007 TNMs." /Mechanics' Institute Chess Club Newsletter 533/ http://chessclub.org/news.php?n=533

For example 12...axb5 13.Rxa8 Qxa8 14.Bxb5 Bxb5 15.Nxb5 Qa1+ 16.Qc1 Qa5+ 17.Nbc3 Rb8 offers some, but not enough compensation. Keep in mind both players are known for their aggressive styles and have a strong preference for the initiative.]

12...c5?!
[12...b4 was a more logical followup.]

[30...Qe2 or; 30...Qe1 , preparing to capture on e4 brings the Queen back into action and keeps an eye on White's dangerous e-pawn.]

31.Qxa5 Bxd7 32.e6
White is still down a rook but this powerful passed pawn balances the chances.

32...Bb5??
[The last mistake costs Black the game. He had to return material with 32...Qg4 33.exd7 Qxd7 intending moves like ...Bg7 and ...d3 keeps Black in the game.]

33.e7 Qg4
The right idea but a move too late.

34.Qd8+ Be8 35.Be5+ Bg7 36.Qxd4 h5 37.Bxg7+ Kh7 38.Bf8

Byambaa (2060) - Cunningham (2280)
Summer Marathon (8),2011


This was a tense game. For both players, a win would tie for first, a draw would likely tie for second, and a loss would get nothing. The main lesson of this game is: when facing a difficult position, keep looking for activity and concrete ideas. Both players rescued bad positions with resourceful play.

 1.e4 Nf6 2.Nc3 e5 3.Nf3 Nc6 4.d4 Bb4 5.d5

My opponent usually plays the 4-pawns attack against the Alekhine. It seemed very likely that she was following my game against Margulis earlier in the tournament, when I played the dubious 5. ... Ne4. This is a line I prepared long ago in pre-Fritz days. It is amazing what you could get away with in the opening before players had computers to tell them what to do!

5...Nb8

White has an edge in this line, but there will be plenty of play for both sides and we have avoided the kind of open game that Uyanga seems to play best.

6.Bd3 Bxc3+ 7.bxc3 d6 8.h3 c6 9.c4 0-0 10.0-0 cxd5

10...Na6 11.dxc6 Qc7 12.cxb7 Bxb7 13.Nd2 Nc5 unclear

11.cxd5 Nbd7 12.Ba3 Qc7 13.Nd2 Nc5 14.Re1 Bd7 15.Rb1 Rab8 16.Nb3 b5

 16. ... b6 is more solid, but feels passive. I had dreams of getting the pawn to b4 and expanding on the queenside, but really this idea is unlikely to work because of White's space advantage.

17.Qd2!?

I had assumed this wouldn't be good because of an exchange of my c5-knight followed by Nh5-f4. But the problem is that Nxd3 prepares the undermining d4 for white and Nxb3 just leaves my queenside too weak. Finally, I didn't want to play 17. ... Nh5 without doing a knight-capture first, because I need the knight ready to come to d6 in the event that White takes on c5. For the first time, I realized that White has a nice edge.

17...Rfc8 18.Re3?!

 Missing the point. White should take over the dark squares on the queenside with 19. Bb4

18...Ne8

18...Na4 19.Bb4 Nb6 20.Ba5

19.Rg3

Continuing a bad plan. Now I think Black is better.

19...Nxd3 20.cxd3 Qc2 21.Rb2 Qxd2 22.Rxd2 b4 23.Bb2 a5?

Throwing away a nice advantage. The most common mistake I see at the Mechanics' Marathons is mismanagement of the clock and I have been guilty of it in this game. Now is the time for Nf6-h5-f4 when I like Black's position. The problem with 23. ... a5 is that I leave my queenside weak and I lose my active Bishop. [23...Nf6!? 24.Re3 Nh5 25.Na5 Rb6 26.d4 f6�]

24.Nxa5 Ra8 25.Nc4 Rxa2 26.Nb6 Rd8 27.Nxd7 Rxd7 28.d4 Nf6 29.dxe5 dxe5?!

29...Nxe4! Unfortunately, the time control was at move 30 and I only had 3 minutes to analyze 30. Rg7+, which leads to a good position for Black. 30.Rxg7+ (30.Rc2� Rd8 31.Rb3 Nc5 32.Rxb4 Nd3 33.Rb3 Rxb2 34.Rbxb2 Nxb2 35.Rxb2 dxe5=) 30...Kxg7 31.e6+ Rxb2 32.exd7 Rxd2 33.d8Q b3.

30.Rc2 Kf8?

Black pays the price for mismanaging the clock.

31.Rc8+ Ke7 32.Bxe5 Nxe4 33.Re3 f5 34.f3 Rxd5

34...Nf6 is much safer. I was not thinking clearly here and was afraid of 35. d6. 34...Nf6 35.d6+ Kf7 36.Rc7 Ra7 37.Bxf6 Kxf6 I think I missed that c3 was not available for a rook here.

35.Bf4 Rd1+ 36.Kh2 Rdd2?!

36...Rf1 37.Bg3?? (37.Rc4 Kf7 38.Rxb4 Rff2 39.fxe4 Rxg2+ 40.Kh1 Rgf2 Same idea as my line but a better version for Black.)37...Raa1-+

37.fxe4 Rxg2+ 38.Kh1 Rgf2?

38...Rge2 39.Rc7+ Kd8 40.Rxe2 Rxe2 41.exf5 b3 Black may hold here, using the b-pawn and the bad position of the White king. 42.Rc1 b2 43.Rd1+ Ke8 44.Kg1 Kf7 45.Rb1 Rc2 46.Bg5 g6 47.f6 h6 48.Be3 (48.Bxh6 Kxf6 I don't see how White can win, but anything is possible.48...g5 49.Rf1� Black may hold here as long as he doesn't run out or Rook moves along the 2nd rank. It makes me a little nervous that I only have 2 of those currently!

39.exf5+ Kf7 40.Rc7+ Kf6 41.Be5+ Kxf5 42.Rf7+ Kg6 43.Rxg7+ Kh6+- 44.Rg1 Ra3

Most players give up in lost positions. You must keep looking for concrete ideas and sources of counterplay. My idea here is that I want to get the pawn to a2 when I think I can draw even after the last rooks come off as long as my pawn stays on h7 (see below). The right move here 45. Rg3 is a little hard to see since the rook just went to g1.

45.Bg7+?!

Pushing my king where it wants to go, Uyanga thought she had a mate here. Rgg3 should win comfortably. The key is to stop the b-pawn before it can be a source of counter play.


45...Kh5 46.Re5+?

It is possible that White cannot win after this careless move. White missed that 47. Bf6 was prevented by the rook on f2. 46.Rxa3 bxa3 47.Rg2 Rxg2 48.Kxg2. Can Black hold here? There is a stalemate trick that may prevent progress. 48...a2 49.Kg3 Kg6 50.Bc3 Kf5 51.h4 Kg6 52.Kg4 Kh6 How does White make progress? 53.h5 a1Q!=; 46.Rgg3 Rfa2.

46...Kh4 47.Re4+ Kxh3

I thought this position was a draw but I was very nervous. I hate positions where my opponent has 2 rooks and my King has no legal moves. At least I am threatening mate in one!

White offered a draw in this position. Although the position is a theoretical draw, White should play on since she has nothing to lose and can only win or draw. White's game is much easier to play also, which is useful in a sudden-death time control. This game had lots of errors, as money-round games often do. But I thought both players played well when they had to."

In Litowsky TNM 2011, I didn't do excellent, 5 out of 9 losing 20 rating points 2124 to 2104, but still played some tough games. Here is one them against FM Andy Lee. It was an another unforgettable and unfortunate draw from  completely winning endgame :(

Now, when i look back to my games, I wasn't that experienced and it seemed somewhat so raw. Having so little knowledge of the game and no studying, all i do was just attack with no fear.  it is possible to beat B or A players even experts with wild attacks  but not always works against masters or decent players who understand chess better... Eventually, I required to play the game more solid and more positional in order to improve the quality of my games. Fall TNM is the one of my very special tournaments because i didn't lost a single game and I drew five games.  it is so rare even I draw a game. In my tournament records, I can hardly find very few games that i drew because I always wanted to win instead of draw and it turns out to be a lost. GM Jesse Kraii mentioned to me once "You should learn how to draw. it's important." Finally, I realize that the only half point can make the all difference.  Start learning to draw is maybe a sign to improving one more step...


Fall TNM 2012
After skipping two marathons in a row, I was excited to come back to TNM, which has been always perfect tournament for me. Every Tuesday night only one game a week,  slow time control and John Donaldson't free lecture before the game and so on. I loved it.   
Round 1, October 16:

Sung,Kevin (1586) - Byambaa,Uyanga (2093)
Mechanics' Fall TNM; 30/90, SD/30 San Francisco (1.8), 16.10.2012

1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Be2 0-0 6.Nf3 e5 7.d5 Nbd7 8.Bg5 h6 9.Bh4 a5 10.0-0 Nc5 11.Nd2 Bd7 12.a3 a4 13.f3 b6 14.b4 axb3 15.Nxb3 Ba4? To be honest, I didn't see that the knight can take my bishop. Very shameful. Maybe because this was the first game after I haven't played chess for about two months and my eyes hasn't open up enough to see the whole chessboard yet I guess. 16.Nxa4 Nxa4 17.Bd3 Qd7 18.Nd2 Nh5 19.Bf2 Nf4 20.Qb3 Ra5 21.Qc2 Rfa8 22.Rfb1 Bf6 23.Rb3 Bg5 24.Nb1 Nc5 25.Bxc5 dxc5 26.Nc3 Kg7 27.Bf1 Nh5 28.Nb5 Nf6 29.Qb2 Ne8 30.Be2 Nd6 31.Rf1 Nxb5 32.cxb5 Bf6 33.Bc4 Qd6 34.Qc1 Bg5 35.Qb2 Ra4 36.Be2 f6 37.Rc3 Rd4 38.Rd1 Raa4 39.Rcd3 c4 40.Rc3 Qc5 41.Kf1 h5 42.Qc2 Rxa3 43.Rxa3 Qxa3 44.Rxd4 exd4 45.Qxc4 Qa1+ 46.Kf2 Be3+ 47.Kg3 Qe1+ 48.Kh3 Kh6 49.Bf1 Kg5 50.g3 Bg1 51.f4+ Kh6 52.Qe2 This tense e, in which the advantage has already gone back and forth, was eventually draw in another 20 moves of mutual time pressure. 1/2-1/2

It was pretty devastating start to drawing my first round with player who rated 500 points lower than me.  /usually first round supposed to be easy but I was wrong./


Round 2, October 23:

Byambaa,Uyanga (2093) - Solomonik,Edgar (1651)

I could take the b5 pawn and i saw that white leaves better at the end. However, i liked the attacking move better and decided to play g6. 18.g6 This is the critical moment of the game. I was pretty proud of myself to find that move. There were 3 different ways to capture the b6 pawn; however, none them is good and it helped me to open up the position for increasing my attacking chances.  Nxf3? Sac wasn't good. He was trying to mix up the position but it wasn't accurate and led him to lose the game. (18... fg hangs the e6 pawn. 18...hg or Nxg6 19. h5 leads to open the h file) 19.Nxf3 a4 20.gxf7+ Kh8 21.Bxe6 Qxe6 22.Ng5 Qc4 23.Qxd6 Nf6 24.Bd4 Nxe4 [24...Bxe4 25.Qxf6!

The game was drawn 50 moves after the f-pawn was captured.

72.Qxb2 Bxb2 73.Kh2 1/2-1/2


Another frustrating draw with lower rated player. The first time I've ever left with bishop and knight. Unfortunately, I had no idea how to do the mate either. Of course, I couldn't figure it out over the board when there was 2 mins left on the clock. At least, I wish I'd have studied it before.  I never thought the knight and bishop mate is gonna be a practical, so studying it would be a just waste of time. However, it wasn't as complicated as I thought when I learned the technique of it  later on.
Even though the game ended a draw, I wasn't feel so bad about it since I made a big mistake to exchange off my queen for the two minor pieces with no counterplay and I fought back hard enough to manage to reached the winning position with excellent piece play.
