NM Hayk Manvelyan is the sole remaining perfect score after three rounds of the Dan Litowsky Tuesday Night Marathon. Uyanga Byambaa had NM Andy Lee on the ropes for much of the evening but poor endgame play enabled him to escape. The two join Experts James Jones, Todd Rumph, Steve Gaffagan and Peter Grey in a tie for second at 2.5 from 3.
Carlos D' Avila won the Wednesday Night Blitz on August 17th scoring 13 from 14.
Visiting Iowa master Tim McEntee shared second with Jules Jelinek with 10 1/2 points.
FM Robin Cunningham sends in detailed annotations to his tough last round battle with Uyanga Byambaa from the last round of the Summer Tuesday Night Marathon.
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!
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.
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.
Missing the point. White should take over the dark squares on the queenside with 19. Bb4
18...Na4 19.Bb4 Nb6 20.Ba5
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 f6³]
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.
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.
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.
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!
48.Be5 Raf3 49.Rxb4 Rf1 50.Rb2 Rxg1+ 51.Kxg1 Kg4
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.
2) Benko-Larsen Exhibition (San Diego 1958)
Over 150 participants and spectators were attracted to the exhibition staged by Chess, Inc., of San Diego, in which the star performers were Bent Larsen, international grandmaster from Denmark, and Pal Benko, former Hungarian Champion and freedom fighter.
The first act was a match game between Benko and Larsen in which the former played White in the San Diego variation of the Sicilian Defense. This opening was stipulated by John Alexander of San Diego, who is chiefly instrumental in arranging the event.
Larsen developed an attack by aggressive play, but Benko had ready answers and soon equalized. Larry Evans, former U.S. chess champion, discussed the game in another part of the playing room. The game was played at a time limit of 30 moves in 30 minutes.
Following the game the masters took on all comers in clock games with a fast time limit. This form of participation was thoroughly enjoyed though the masters, as expected, scored all the points.
