Girls Nationals Games

So (first of all) hats off to a few students:

1. Jasmine Fermin (tied for first in the 14 and Under section), who managed two rook sacs in one tournament. Notice Angelica behind her, cracking up.

Jasmine Fermin - Nymisha Rao
1.Rxg7 [1.Qg6! is "better" according to computer-- black must defend with Qg8 and then Be4 wins the Nc6-- whatever]

1...Kxg7 [1...Rxg7 2.Qxh6+ Kg8 3.Qxe6+ Kh8 4.Qxc6]

2.Qg6+ Kf8

3.Qxe6 Qxd3

4.Qxh6+ Ke7

5.Qxc6 +-

Tara Lamberti - Jasmine Fermin

White unwisely took on d6 (20. Qxd6) , and Jasmine unleashed
20.... Rxb2+!

21.Ka1 [21.Kxb2 Qc2+ 22.Ka1 (22.Ka3 Nb5+ 23.Kb4 Nxd6) 22...Qxd1+]

21...Rxa2+! -+

2. Rochelle Ballantyne, winner of the 14 and Under Section, for this spectacular queen trapping:



27. Rec1! (although I should say that 27. Rf1 looks very good also-- if black ignores it white will double or triple on the f-file; if black takes on f1, white recaptures with the rook and threatens 29. Bxg6 hxg6 30. Qxg6 and 31. Rf7, winning. Thanks to Mr. Andrei Zaremba for that insight.)

27... Ng7 [I suggested 27...a6, but it doesn't help after 28.Bc2 Qb5 29.Bc5 Rf7 30.a4 Qc4 31.Bxg6-- point is that if black trades queens, white throws in the zwischenzug 32. Bxf7+]

28.Bc2 Qb5 [28...Qa6! is much better: 29.a4 Bd7]

29.Bc5 Rf7

30.a4 Qa6

31.b5 Qa5

32.bxc6 +-

3. And the big hero, Angelica Berrios, winner of the 16 and Under section (she's 14):

Robinson,Darrian - Berrios,Angelica [C02] Girls Nationals, 29.04.2008

1.e4 e6
2.d4 d5
3.e5 c5
4.c3 Nc6
5.Nf3 Qb6
6.Be2 Black's basic plan in this line is to take on d4, play Ng8-h6-f5, Be7, 0–0, f6 and get some attack going on the f file. Angelica's play is logical and thematic.

6...cxd4
7.cxd4 Nh6
8.b3 Nf5
9.Bb2 Bb4+
10.Kf1 Bd7 [10...Be7 maybe it's a more popular move-- the idea is that on g4 black can play Nh4]

11.Nc3 [11.g4 Nh6 12.Rg1]
11...Qd8 [11...Ncxd4 12.Nxd5 exd5 13.Nxd4 Nxd4 14.Bxd4 Bc5 Angelica saw this and thought (correctly) that it was equal. ]
12.a3 Be7
13. g3 f6

14.Kg2 a6
15.Qd2 fxe5
16.dxe5 0–0

17.Rad1 White is playing planlessly here. She needed either to attack with g4 and Rg1 earlier, or maybe now still she can play b4-b5.

17...Be8
18.h3 Bc5 stage one: hitting f2. She says to me at this point (at this point in analysis, obviously), "Here I thought she would play Bd3, but I had calculated it lost." My response-- "Huh? Seriously?"
19.Na4 Ba7
20.Bd3 Bh5
21.Be2 [21.g4 Nh4+ 22.Nxh4 Qxh4 23.Rdf1 Bxg4 24.hxg4 Qxg4+ 25.Kh2 Rf3]
21...Bxf3+
22.Bxf3 Nfd4
23.Bxd4 Nxd4

24.Bg4 Nxb3

25.Bxe6+ Kh8

26.Qe1 Rxf2+

27.Qxf2 Bxf2

28.Rxd5 Qe7 they played a few more moves but 0-1



Reuder,Emma - Berrios,Angelica [A84]
Girls Nationals, 29.04.2008
1.d4 e6

2.c4 f5

3.Nc3 Nf6

4.Nf3 d5 After the game Angelica said she thought she was supposed to play Bb4, but it seems like everyone else plays 4...d5 too.

5.Bg5 c6

6.e3 Bd6

7.cxd5 exd5

8.Bd3

8... 0–0
9.Qc2 h6
10.Bh4 Qe8
11.Bxf5 Bxf5
12.Qxf5

12... Ne4 In the game and afterwards, we both thought Angelica had somehow messed up in losing the pawn, (she suggested moving the queen somewhere instead of castling) but she's making Rybka's first choice each time. [in analysis we (ok, mostly Angelica) found the following hilarious line: 12...Nh5 13.Qg4 (better is 13.Qc2) 13...Rf4 14.Qh3 g5 15.Bg3 (15.g4!) 15...g4 16.Qh4 Be7]
13.Qh3 Nd7
14.Nxe4 dxe4
15.Nd2 Bb4
16.a3? [16.0–0–0; 16.Rd1]
16...Bxd2+
17.Kxd2 Nb6 [17...c5 Angelica rejected this because of 18.d5 Ne5 19.Qe6+]
18.Ke2 [18.Rac1!]
18...c5
19.Rhd1 cxd4
20.Rxd4 Rc8 [20...Qb5+ 21.Ke1 Qxb2 22.Qe6+ Kh8 23.Rad1=]
21.Qg4 [probably white should run with her king: 21.Kf1 Rc2 22.Kg1 Qf7 23.Rf1 Nd5 24.Rxe4 Rxb2]
21...Qb5+
22.Ke1 Qxb2
23.Qe6+ Kh8
24.Qa2
24...Rc1+
25.Rd1 Rxd1+
26.Kxd1 Qb5
27.Qe2 Qa4+ [27...Qe5]
28.Qc2 Qd7+
29.Qd2?? Qg4+ 0-1

both of which are good.

Lots of Nationals and I'm So Tired

Sorry I haven't posted in ages, I've been busy attempting the quadrathalon of scholastic chess nationals--just got back from Dallas 1 hour ago (girls'). Last weekend was Atlanta (high school), and two weeks from now is elementary (Pittsburgh). I doubt I can string together a coherent thought, but here's some pictures for you. Sometime soon I'll post some games, positions, and a story or two. Caroline Zhu, under 12 winner
Amanda Mateer and Emily Francis -- High School bughouse champions
Courtney Jamison, who will play in the US Women's Championship next month. She came second in the Girls 18 and Under section last weekend.

Medina Parrilla, winner of the 18 and Under
Darrian Robinson, Jasmine Fermin, and Angelica Berrios. It may not look likely, but their average rating is 1700.
Jasmine and Angelica

My Afterschool Game With Darrian

So in afterschool today we played a G/60, in preparation for High School Nationals, Girls Nationals, Elementary Nationals, etc. I had felt like one of the problems at Junior High Nationals was that the kids are just too used to G/30. Note to coaches out there: you can buy a USCF affiliate thing for $30 and it allows you to rate the games played in club. This makes the kids take it super-seriously. So Darrian doesn't usually come to afterschool, but she did today so we celebrated by playing each other.

(194) Robinson,Darrian - Vicary,Elizabeth [B34]
afterschool 14.04.2008
1.e4 c5
2.Nf3 g6

I just started playing this-- not sure if I'm going to stick with it, but I figured why not. Darrian just started playing the Open Sicilian, so I wanted to play something less weird than the Sveshnikov, in order to get a better feel for how well she understood things. The Svesh is just so bizarre that no one can play against it decently without some specific knowledge.

3.d4 cxd4
4.Nxd4 Nc6
5.Nc3 Nf6

Already I couldn't remember anything, but whatever, I was getting paid money to play a game of chess, so what do I care?

6.Be3 d5

Obviously I knew this was an incorrect move, but I couldn't see an immediate refutation, and I was curious what she would play.

7.Bb5 Bd7

This is the best move: anything else and white will take on c6 with the knight first:

7...dxe4 8.Nxc6 bxc6 9.Bxc6+ Bd7 10.Bxa8 Qxa8;
7...Nxe4 8.Nxc6 bxc6 9.Bxc6+ Bd7 10.Qxd5

8.exd5 Nb4
I can trade stuff, but I thought I would just be down a pawn for nothing after something like

8...Nxd4 9.Bxd7+ Qxd7 10.Qxd4 Bg7 11.0–0–0

She thought for a long time and played

9.d6

I had expected 9.Bc4 when I was planning 9....Rc8 10.Bb3 Bg7 (I'm going to take on c3 as soon as she played a3, but not before) 11.a3 Rxc3 12.bxc3 Nbxd5. I missed, however, that she should take the knight with 12.axb4! since my a7 pawn will be hanging after I retreat the rook. Fritz likes white but suggests 12... Bg4 13.Nf3 Rxb3 14.cxb3 a6

9...exd6
10.Qe2 Be7

This move is very bad-- I missed how strong Bh6 would be. I should just play 10...Bg7 11.Bg5+ Qe7.

11.Bh6

11...Rg8
12.0–0 I was happy to see this. 12.0–0–0 puts mroe pressure on me.
12...a6
13.Bc4 Nc6

Fritz wants to play 13...d5, and I considered it, I just thought defending this pawn all game would be more of a drag than defending the light squares.

14.Rad1 Ne5
15.Bb3

Probably unnecessary. My knight on e5 is one of my few active pieces, so while her bishop is good, something like 15.Rfe1 is better. Fritz line: 15... Nxc4 16.Qxc4 Rc8 17.Qb3 g5 18.Rd3 Rg6 19.f4 gxf4 20.Bxf4+/-

15...g5

16.Ne4

So I was expecting 16.Bxg5 Rxg5 17.f4 when I wasn't sure how 17....Bg4 would turn out. Seems like it's good for me after 18.Qe3 Rh5 19.fxe5 Rxe5.

Fritz wants to play 16.h3! with the idea of going into the above line, but preventing ....Bg4: 16...Rg6 17.Bxg5 Rxg5 18.f4 Rg6 19.fxe5 dxe5 20.Nf3 Qb6+ 21.Kh1 Bc6 (21...Be6 22.Nxe5) 22.Bxf7+ Kxf7 23.Nxe5+.

16...Bc6?

I didn't know what to do. A hilarious computer line: 16...Rg6 17.Bxg5 Nxe4 18.Bxe7 Qxe7 19.Qxe4 Bg4 20.Rde1 (20.f3? Nxf3+) 20...Bh3 21.Ba4+

Now here's the big question: which way should the king go? Turns out that 21...Kd8 is better because we can take on g2 with the bishop and nxg6 won't be check later so black will have time to play Nf3+ and pick up another exchange. See:

21...Kf8 22.Nf5 Bxf5 (22...Rxg2+ 23.Qxg2 Bxg2 24.Nxe7 Bxf1 25.Kxf1 Kxe7 26.f4!; 22...Bxg2 23.Nxe7 Bxe4+ 24.Nxg6+ Bxg6) 23.Qxf5 Kg7±)

21... Kd8 22.Nf5 (better is 22. g3) Bxg2 23.Nxe7 Bxe4+ 24.Nxg6 Nf3+!

17.Nxc6? [17.Nxg5 Bxg2 18.Qxe5 (18.Kxg2 Nfg4 19.Bxf7+ Nxf7 20.Qxg4) 18...dxe5 19.Bxf7+ Kd7 20.Nde6+ Kc8 21.Rxd8+ Rxd8 22.Kxg2+-]

17...bxc6

18.Bxg5 Better is 18.f4 gxf4 19.Bxf4

18...Nxe4

19.Bxe7 Qxe7

20.Qxe4 d5

21.Qxh7 0–0–0

I was feeling much better here. Fritz still likes white as much as ever (1.3), but I'm not suffering in the same way and I felt I had some initiative. Also she had 5 minutes to my 25.

22.Qf5+ Kb7

23.Rde1 Dunno why she didn't play the other rook.

23...Rg5

24.Rxe5?!?! After the game she called this a sacrifice-- at the time I thought she hung it but I guess I believe her. 24.Qf4 is obviously better.

24...Qxe5

25.Qxf7+ Kb8

26.Qf3 Rdg8

27.g3 Rh8

28.Ba4 Rg6

29.Qd3 Rgh6?? [29...Qh5 mates immediately. I'm an idiot.]

30.Qxa6

I had a long think here.

30...Rxh2 is bad because of 31.Qb6+ Kc8 32.Qxc6+ and the best I can do is repeat with 32...Kb8= (32...Qc7? 33.Qa8+ Qb8 34.Qxb8+ Kxb8+-; 32...Kd8?? 33.Qd7#) ;

30...Qe4 was my other choice, but it loses to 31.Qb6+ Kc8 32.Bxc6+-

30...Qc7 Nice and safe.

31.Qe2

I dismissed 31.h4 in the game because of 31...Rxh4, but white can not take back and run with the king instead: 32.Bxc6 Rh1+ 33.Kg2 R8h2+ 34.Kf3 Qf7+ 35.Ke2 Qe7+ 36.Kd1 Rxf1+ 37.Qxf1±

31...Rxh2

32.Qf3 Qh7

32...Qd7 is better: 33.Bb3 (33.Qb3+ Kc7; 33.Re1 Qh3 34.Qf4+ Kc8) 33...Qh3 34.Qf4+ Kc8.

33.Qf4+ Kc8

34.Qg4+ Qd7

35.Qxd7+ Kxd7

36.f4 Rd2

37.Rf2 Rd4

38.Bb3 Ke6

39.Kg2 Kf5

Ooops-luckily she had 10 seconds left and so didn't see it, but I'm ashamed of myself.

40.Kf3 [40.c3!]

40...Rg8

41.Re2 Re4

42.Rf2 Re1

43.Re2 Rxg3+ 0–1

answers

Position 1: Abadel (under 1000!)

So at first I thought Abadel's move: 1. Be7 was brilliant. the idea is 1... Bc1 2. Bd6+ Kxd6 3. e7! But it turns out this only draws after 1.... Bxe7 2. Kxe7 b4! (2... d4 is less good, since white can take and push the d pawn to attack the black king: 3. cxd4 c3 4. d5 c2 4. d6+ Kb7 6.d7 c1=Q 7. d8=Q Qg5+ 8. Ke8 Qh5+ 9. Kd7 Qd5+ 10. Ke7 Qg5+ and because of the advanced e pawn, black is only drawing)

So back to 2...b4! 3. cxb4 c3 4. Kf7 c2 5. e7 c1=Q 6. e8=Q and black is winning, at least according to Fritzy.

The best move is definitely 1. Bh6, simply intending 2. Bf8. Black gets nowhere with 1...d4 2. cxd4 c3 3. d5 c2 4. e7 Bxe7 5. Kxe7 c1=Q 6. d6+, since the bishop guards c1.

Position 2: (Rawn) Black had been defending this position for ages, and he made the psychologically classic mistake of 1... c5. The problem is that once the rooks are all traded, white can take on f6 and play h5, making a passed pawn. Nice teachable moment for resisting the urge to simplify! Instead, ....Rb1, intending ...Rh1, or ... f5, forcing white to fix the pawn structure, are both holding without too much trouble.



Position 3 At first I thought 1... h5 was the best, with the variation 2. Qxh5 Rh6 3. Qxh6 gxh6, but the truth is that 1.... Qxf1 is simple and obviously better.



Position 4 Najeebah's move 1. g3 is a horrible blunder, allowing 1... g4, making a passed h pawn.

Junior High Nationals-- At Least My Predictions Were Right

So the results were something of a let-down: third in open, 3rd or 4th in under 750, and I don't even know what in the other unders. I guess I'm disappointed, although not as much as I expected to be. Seems kinda stupid to let yourself truly be emotionally depressed about the results of children playing a board game. A couple of them played stupidly, and that bugs me, but one or two played well and worked hard, so I guess that evens things out. Angelica was the big star, to me at least-- she beat Vincent Zhang Saturday night in an exquisite good knight vs bad bishop ending. Sunday she played two experts and lost both but played for four hours each game and fought hard in each one.

OK, here are a few quiz positions for you from kids' games. Answers tomorrow-- I'm too lazy tonight.

White to move-- what's the best move and what's the evaluation? (Abadel, round 6)

Black to move-- what's the best move and what's the evaluation? (Rawn, rd 6)

Black to move-- best move? (Milo Pan- Davon)

White plays 1. g3. Why is this losing? (Najeebah - Caleb Deal)

Danger: Keep All Children Away From Carousel.

MORE CHESS!!!!

I absolutely cannot bear to spend any more class periods reviewing openings (nationals in 2 days) and I'm lazy, so tonight I'm thumbing through books for randomly interesting puzzles that I can mash together and call a "lesson." I came across four so beautiful that I felt the need to share with you guys. Weirdly, they were all on the same 2 pages of the book. Or maybe that's not so coincidental and I'm just in an easily impressed frame of mind.

Novelty of the Century

After so many years in chess,when you think you have seen everything, it is still amazes you in a way you can never imagine. Small wonder that it was “Vassily,” who did it again, one of two most creative geniuses of modern chess. Just him and Morozevich.

Fisher’s favorite method of treating Najdorf. Recently it was on a spike of popularity again, thanks mainly to the efforts of Rublevsky and Volokitin.

6…e6
7. Bb3 b5

For years 7…b5 was considered the most reliable way of equalizing for black. The alternative 7…Nbd7 (7…Be7 8.g4 is way too passive for black) 8.Bg5! (much more aggressive than an old move 8.f4) Qa5 is now under heavy fire after both 9.Bxf6 Nxf6 10.0-0 (with the idea of f4-f5) or simple 9.Qd2, followed by 0-0-0.

What happens next in the featured game can only be compared to the feeling, when whatever you’re dropping to the ground, defies gravity and flies to the outer space.




14. Qxe6+!! fxe6
15. Nxe6

Gregory Kaidanov teaches that whatever happens on a chess board you should try to put in words, before proceeding to calculations and variations. So let’s do just this. "White sacrificed his queen (worth 9 pawns,by the way) for 2 pawns(!) then continues to play as if nothing happens (just making quiet moves)”


Same description,using Larry Christiansen’s method, will be looking much more laconic: “Sickening.”

15… Qe5

Facing the novelty of the century in a rapid game(!!), Karyakin makes a practical decision – to return the queen for a rook…….and forcedly ends up in a hopeless endgame!

Let’s try to figure out if there’s more than just a “shocking value” to 14.Qxe6.
First of all ,black cannot decline the offer by playing 14…Kf8. After 15.Bxf6 Bxd4 (15…Nxd4 16.Bxg7+ Kxg7 17.Qg4+ Kf8 18.Rxd4)16.Nd5! fxe6 (16…Bxf6 17.Qxf6)17.Nxc7 Bxf6 18.Nxe6 Ke8 19.Rhe1 Rb8 20. Nxg7+ Kf8 21.Ne6+ Ke8 22.Nd8+ Kf8 23.Nxb7 Rxb7 24.Re6 Bg5+ 25.f4 Nd8 26.fxg5 Nxe6 27.Bxe6 we getting our magical 3 pawns for the exchange with an easy winning position.

Then, since 15…Qe5 allows white to win a third pawn on g7 and therefore makes a queen sac for a knight in return kinda senseless, because white is already better materially – the only realistic possibility by black (and Fritz/Rybka confirms) is to sac queen back for a knight on e6 by playing 15…Qe7.

White has two ways to continue his spectacular play, the most obvious 16.Rhe1 and very interesting 16.Nd5. Incredibly black’s only defence after 16.Nd5 is “the answer in kind” 16…Nd4!! (the endgame after 16…Nxd5 17.Bxe7 Ncxe7 18.Nxc5 0-0-0 19.Rhe1 Bc6 20.Nxa6 Kb7 21.Nb4! Kb6 22.Nxc6 Kxc6 23.a4 is very bad for black). After 16…Nxd4!!,white avoids the danger after 17.Nxe7 Nxe6 18.Bxf6 Bxe7 19.Bxe7 Kxe7 20.Rhe1 Bc8 21.Rxe6 Bxe6 22.Re1 Rhe8 23.Rxe6+ Kd7 24.Rxe8 Rxe8 25.Kd2, but he certainly can’t win.

After 16.Rhe1 Qxe6(the only one) 17.Rxe6+ Ne7 18.Rde1 (less challenging is 18.Bxf6 gxf6 18.Bd5 Bxd5 20.Nxd5 Rd8!21.Nxe7 (white is also hardly in a danger of losing after 21.b4 or 21.Nxf6+) Kf7 22.Rde1 Rde8 23.Rxa6 Rxe7 24.Rxe7 Bxe7 25 Ra7 b4 26.Kd2 and draw is the most appropriate result), black has few choices, namely 18...Rd8, 18…0-0-0 and 18…Kd7. First two lead to a very pleasant endgame for white after 19.a4 b4 20.Bxf6 gxf6 21.Ne4 Bxe4 22.R1xe4. White is going to get third pawn for a piece and the question only remains if his technique would be enough for conversion. So it looks like 18…Kd7 is the only defensive option for black and white has a choice between repeating the position after 19.Rd1+ Ke8 20.Rde1 and continuing to play for a domination in the center of the board with 19.f3!?


16. Nxg7+ Kf8
17. Ne6+ Kf7
18. Rhe1 Qxe1
19. Nxc5+ Kg6
20. Rxe1 Kxg5
21. Nxb7 +-

Three pawns for the exchange is too much and Vassily finishes in style,using his impeccable technique.
