Big Announcement from Wisconsin Chess Association President Mike Nietman

To all:

Earlier this evening I received a phone call from USCF Executive Director Bill Hall and National Event Director Pat Knight Smith who told me that Bill had just signed a contract with the Madison Marriott West in Middleton (just off the Beltline at Greenway Blvd.) to host the 2013 US Open Chess Championships!!

The event will be held Saturday, July 27 – Sunday, August 4 and is a nine round event.  Traditionally there have been at least three schedules to choose from.  The Traditional schedule is one round per night at 7 or 7:30 pm for nine days except the last round which is usually at 3 pm on the last Sunday.  The Six Day schedule starts Tuesday and plays two rounds Wednesday, Thursday and Friday to catch up.  Both the Traditional and Six Day time controls are 40/120 SD/1.  The third schedule is the Four Day which starts on Thursday and plays six rounds of G/60.  All sections merge Friday night for the last three rounds at 40/120 SD/60.

In addition to the main event, there are day tournaments, the US Open Blitz Championship, a Fischer 960 (Random) tournament, USCF Sales bookstore, workshops and lots more!  Two very prestigious invitational events take place at the US Open as well.   They are the Grandmaster Arnold Denker Tournament of High School State Champions and the Dewain Barber Tournament of K-8 State Champions.  As the host state, we will be allowed to enter a second participant in these events in the event there is an uneven number. 

Room rates at the Marriott will be $99 but you may have up to four in a room.  About a dozen restaurants in all price ranges are within a ten minute walk as Greenway Station is renowned for its eating and shopping culture.

The US Open was last held in Wisconsin in 1953 or 1954 in Milwaukee.

In 2006 the Wisconsin scholastic chess community turned out in large numbers for the National High School Championships.  Now it is everyone’s turn to show the national chess crowd that we can support a large open, national event!

Much more later!

Championship Summary/Chess in the Fall

Area Chess Club Finishes 1st Annual Club Championship

The River Valley Community Chess Association (RVCCA) finished up their first annual club championship recently. The club, formed three summers ago by high school friends looking to bring chess into the local community, has grown greatly since its initiation. The club championship was divided into two levels: Scholastic (16 and under) and Regular. The championship was open to all chess players in the lower WI river valley area that were members of the club. The format was a double round robin played over several weeks, allowing all participants to play each other twice, once as each color. 1st prize for the scholastic champion was a laser engraved crystal trophy, while the 1st prize for the regular club champion was a walnut decade traveling trophy.

Tentative schedules for those meetings call for skittles (fun) games, lessons, puzzles, and competitive games. With a beginner/refresher lecture at the same time September 17th.

August 17th, 2011
Time Control: G/60 +5
[English opening (A13) |>| Nimzo-Indian: Leningrad Variation (E30)]

English opening (A13)

1…e6 2.Nc3 Nf6 3.d4 d5
What started out as an English Opening transposed into a Queen's Gambit Declined.

4.Bg5 h6 5.Bh4
Possibly better was Bxf6.  If Black recaptured with his queen, White could win the d-pawn; if Black recaptured with the g-pawn, then he'd have doubled pawns (although this may not be too bad for Black, especially if he were to castle queenside vs White castling kingside).

Transposes into a variation of E30: Nimzo-Indian: Leningrad Variation

e3 protecting the c-pawn is stronger; White would be OK trading his knight for bishop, even though doubling his pawns.

6…c5=/+ 7.e4?
[Better is: 7.e3=/+ and White could well hope to play on]
Loses a pawn...

7...g5-+ 8.e5??
[shortens the misery for White]
[Better is: 8.exd5 gxh4 9.a3 cxd4 10.Qxd4 Bxc3+ 11.Qxc3 exd5 12.Nf3-+ ]
Now loses a piece...

[8...gxh4?! is clearly worse 9.exf6 cxd4 10.Qxd4-+ ]

[9.Qc2 does not save the day 9...Qa5 10.0-0-0 Bxc3-+ (10...gxh4?! is no comparison 11.Nxe4 dxe4 12.a3 Bxa3 13.bxa3-+ ) ]
Allows trading of queens & loss of a pawn (or 2?), in addition to losing a piece.
White resigns to the fact that the bishop is gone and tries for a startling move and damage control.

[Better is: 9...Nxc3 and Black can celebrate victory 10.a3 Ba5 (10...gxf4?! is easily refuted 11.Bxd8 Nc6 12.axb4 Nxb4 13.bxc3 Nc2+ 14.Kd1 Nxa1 15.Bf6-/+ ; 10...gxh4?! is a bad alternative 11.axb4 Ne4 12.f3-+) 11.bxc3 Bxc3+ 12.Ke2 Bxa1-+ ]

10.a3 Bxc3+
[10...Ba5!? makes it even easier for Black 11.b4 cxb4 12.Nxe4 dxe4 13.Qxe4 bxa3+ 14.Kd1-+ ]

11.bxc3 Nxc3
[11...Qa5 and Black can already relax 12.Ne2 cxd4 13.cxd5 exd5 14.f3-+ ]

12.dxc5 Qa5 13.Nf3
[13.Qd2 doesn't change the outcome of the game 13...d4-+ ]

If Black wanted to attack White's king, he'd be better off developing his queenside pieces prior to embarking on checks that are easily parried.

14.Nd2 Qc3
[Better is: 14...Nc6 might be the shorter path 15.Rd1 Nc3 16.cxd5 exd5-+ ]
The previous check would have made more sense if Black intended to trade queens & knights (which he could enforce and would be a good idea, since he's ahead a piece).

[15.Rd1-+ otherwise it's curtains at once]
This move loses the rook via Qc1+ 16. Ke2 Nd3+ forking king & rook.  Better was Rd1, protecting the knight and keeping Black from trading off pieces.

[Better is: 15...Qc1+ keeps an even firmer grip 16.Ke2 Nc3+ 17.Kf3 Qd1+ 18.Ke3 Nc6-+ ]
Black missed the tactic & settled for grabbing a pawn.  He still had a winning position though.

[16.Qf3 cannot change what is in store for ? 16...Qxe5+ 17.Qe3 Qxe3+ 18.fxe3 b6 19.cxd5 exd5-+ ]
This move loses the queen via Qc1+ 17. Bd1 Nd3+ forking king & queen.
[Better is: 16...Qc1+ makes sure everything is clear 17.Bd1 Nd3+ 18.Ke2 Nxf4+ 19.Ke1 Nc6-+ ]
Black again missed a knight fork, but trading pieces retained his winning edge.

17.Bxd3 Qxd3
[17...Qc1+ makes it even easier for Black 18.Ke2 Qxh1 19.Rc2-+ ]

[18.cxd5 does not improve anything 18...exd5 19.Qxh4 Rg8 20.Qxh6 Nc6-+ ]

[Better is: 18...Nc6-+ seems even better]

[19.Qxc4 what else? 19...Qxc4 20.Nxc4-+ ]

19...Rf8 20.Qxh6 c3 21.Qg5
[21.Qxh4 is no salvation 21...Nc6 22.Qg3 cxd2+ 23.Rxd2 Qe4+ 24.Kf1 Qb1+ 25.Ke2 Qb5+ 26.Qd3 Qxe5+ 27.Qe3 Qh5+ 28.Qf3 Qh4-+ ]
White sets a desperation trap...
Black's greed loses his queen, since Rxd2 pins the queen to d8, a checkmate square.

22.Rxd2 Qc3???
[Better is: 22...Qe4+ and Black has prevailed 23.Qe3 Qxg2-+ ]
Loses instantly.  Black would still have been in the game with a +2 material advantage if he had traded queen for rook, instead of moving the queen out of the way.
White Mates

Black outplayed White for most of the game, but committed a few vital sins (notably leaving his king exposed and not developing his queenside pieces) & then made a couple of major blunders that allowed White to swindle the win.

[Dutch (A80)]

1.d4 f5
[Dutch (A80)]
The Dutch Defense surprised White, who was expecting the Queen's Gambit Accepted from Black.  White had never faced this defense before & neither had he studied it.  Kudos to Black for coming up with an unexpected opening; throwing White off his game.

2.e3 e6 3.c4 Nf6 4.Nc3 Be7 5.Bd3 b6 6.Qf3 Nc6= 7.d5
[White threatens to win material: d5xc6 {7.Qd1 Bb7 8.Nf3 Nb4=}]
Not a strong move, and not in line with the style White usually plays.  Although it seems to be aggressive, it actually leads White into a passive position.

[Black threatens to win material: Nb4xd3 {7...Ne5 8.Qe2=/+}]

8.Bb1= Bb7 9.a3
[White threatens to win material: a3xb4 ]

9...Na6 10.Qe2
[10.b4= ]
White was looking at a potential tactic on the knight on a6, but it would have been better to simply develop.

[10...Nc5!? might be a viable alternative 11.Qd1 0-0=/+ ]

[11.Nf3 exd5 12.Bxf5 Nc7+/= ]

11...Bxc6= 12.Nf3 0-0 13.0-0 Nc5 14.Bc2 Nfe4 15.Nxe4 Nxe4 16.Ne5
Nd4 may have been the better square to attack the bishop from.

The bishop was a strong piece, so Black likely would have been better off moving at back rather than allow White to exchange it.

17.Nxc6 Rxc6 [White has the pair of bishops]

[18.Ba4!? Rc7 19.Bb3= ]
White goes into a funk and plays several inferior moves over the next sequence.  f3 driving away the knight is stronger and keeps the game relatively even.

 18...Rxc4 19.b3??
[Better is: 19.Bd3 is the best chance 19...Ng5 20.Qe2=/+ ]
Blundering a piece.  Qe2, protecting the bishop; attacking the rook was a better move here.  As stated above, White should never have moved the queen from e2 in the first place.

19...Rxc2-+ 20.Qd1 Bf6
[Better is: 20...Qc7 and Black can already relax 21.f3 Nf6 22.Bd2-+ ]

[21.Qxc2 cannot change what is in store for ? 21...Bxa1 22.f3 Nc3-+ ]

[Better is: 21...Ra2 might be the shorter path 22.Qd3 Be5 23.f4-+ ]
Being down in material, White did not want to trade off pieces, but that was a mistake in this situation.

[22.Bb2-+ what else?]
Another blunder, as this allows a knight fork; black the loss of the exchange (rook for knight). 

22...Nc3 23.Qc2
[23.Qd3 doesn't change the outcome of the game 23...Nxb1 24.b5 Rc5 25.Qxb1 Qb8-+ ]

23...Nxb1 24.Qxb1 Be5
[24...Qc7 keeps an even firmer grip 25.Bd2 Rc2 26.Be1-+ ]

[25.Bb2 is no salvation 25...Bxb2 26.Qxb2 Qc7-+ ]
Although White does not want to exchange pieces, he should again strongly consider Bb2, since his dark squared bishop is a weak piece, and Black's counterpart is stronger.

[Better is: 25...Qc7!? seems even better 26.Bd2 Bxh2+ 27.Kf1-+ ]

26.g3 Qh3
The next several moves feature a lot maneuvering - Black looks to bring an attack on White's king & White first tries to set up defense; then tries to create counterplay.

[27.Bb2 doesn't get the cat off the tree 27...Bxb2 28.Qxb2 Rfc8-+ ]

[Better is: 27...Rfc8 secures the point 28.Qd1 Rxc1 29.Qxc1 Rxc1 30.Rxc1-+ ]

[28.Bd2 doesn't change anything anymore 28...Rfc8-+ ]

28...Bc3 29.Rf1

30.Qe2 d4 31.Qb5
[31.b5 doesn't do any good 31...Rc5-+ ]

31...Rh6 32.Rf2 Rc8 33.Qd7
[33.Rc2 a fruitless try to alter the course of the game 33...Qh5 34.Qf1 Rd8-+ ]

White has successfully achieved getting his queen to a threatening position.  Black still has a lot of pieces around White's king, but White is secure for the time being.

[34.Qc6 cannot change destiny 34...Qh5 35.h4 Rg6-+ ]

34...Be1 35.Rg2 Bxg3!
[Decoy: g3 ]

[36.Rxg3 Qxh2+ Decoy Double attack; 36.hxg3 Qh1+ Skewer; With the idea: 36.-- Bxh2+ Wins material]
White sets a desperation trap and prays for a major oversight.

[36...Qh5 37.hxg3 Qh1+ 38.Kf2 Qxc1 39.Kf3 Qc3+ 40.Kf2 Rc8 41.Qxc8+ Qxc8 42.d5 Rh1 43.Rg1 Qc2+ 44.Ke3 Rxg1 45.Kd4 Rd1+ 46.Ke5 Rxd5+ 47.Kxe6 Qe4# ]
White's prayers are answered... Black was up by +8 (by tChess analysis) before this move & appeared to have the game well in hand.

White Mates
Black had significantly outplayed White for most of this game, but his only blunder lost the game instantly.

[not a good decision, because now the opponent is right back in the game {Better is: 20.g4!? hxg4 21.Rxg4+}]

[Black gains space {20...Qg4 21.Qxg4 hxg4 22.h5=}]

21. a4
[21.axb4 cxb4 22.g4 hxg4 23.Rxg4+- ]
[Better is: 21...Qg4= and Black can hope to survive]

22. g4 Rh8?
Black should trade pawns with hxg4, as the move played simply loses the h-pawn (or worse) because of the pin on the g-pawn.
[Better is: 22...hxg4 23.Rxg4 Qe7+- ]

23. gxh5 Rxh5??
Black doesn't realize the g-pawn is pinned and thus the rook has no guard and is hung.
[23...Qe7+- is the last straw]

24. Qxh5 Rh8 25. Qg4
[25.Qf3 seems even better 25...Rxh4 26.Rxh4 Bxh4+- ]

25...Qe8 26. Kb2
[26.h5 seems even better 26...Qd8+- ]

26...Qe5 27. f4
[27.h5 Kf8 28.hxg6 Rxh1 29.gxf7 Rxg1 30.Qc8+ Kg7 31.f8Q+ Kg6 32.Qh3 Bh4 33.Qxh4 Rb1+ 34.Kxb1 Qh5 35.Qff6+ Kh7 36.Qxh5# ]
27...Qe8 28. f5
[28.h5 might be the shorter path 28...Rh6 29.Qf5 Qe7+- ]
Removes an important defender of the g-pawn that allows White to win that pawn and set up a devastating attack on the king.

29. h5?? 
White loses the opportunity to win the g-pawn, and allows black to lock up the position on the kingside.  White still retains a significant material advantage, but the position is much tougher to crack now.

29... g5! 
Locks up the pawn structure and thus makes life harder for White.  Drawing chances have increased considerably...

30. Qh3 
[30.h6+ makes it even easier for White 30...Kf8+- ]

Hangs the f-pawn.
31. Bxf7 Rh7 32. Be6
[32.Bg6 keeps an even firmer grip 32...Rh8+- ]

32...Qf8 33. Rg4 Rg7 34. Rhg1 Qe7
Having locked up his side, Black starts the process of waiting.

35. Qh2 Qf8 36. Qd2 Qe7 37. Qc1 Qf8 38. Rxg5?? [!]?
White tries to break open the position, but this move just loses a rook.
[Mate threat]?

38... Bxg5 
[38...Bxg5 39.Qf1 Combination; 38...Rxg5 39.Qf4 Combination; With the idea: 38...-- 39.Rg6+ Mate threat]

39. Rxg5??
Loses the exchange.  This series of exchanges changed the evaluation from a winning position for white, to a nearly equal position.
[Better is: 39.Qd1+- secures the point]

40... Rxg5 40. Qf1??
[White lets it slip away {Better is: 40.Qf4!?+- }]

[40...Qe7!?+/= ] 

41. Qh3 Kh6 42. Qh4 Rxh5 43. Qf4+
White can salvage a draw with perpetual checks by his queen.
(There was a win for White even after 43.Rg5....but it took over 40 moves for a computer to find)

43...Rg5 44. Qxd6???
White simply gives the queen (and the game) away...

[an unfortunate move that relinquishes the win {44.f6+/- }]

White Resigns

Game of the Week

RVCCA Ladder Match
Arcadia Books and Café, Spring Green, WI.
July 14th, 2011
Time Control: G/45 +5
[Queen's Gambit Accepted (D20)]

1. d4 d5 2. c4 dxc4
Queen's gambit accepted (D20)

3. e3 Nf6 4. Bxc4 e6 5. Nf3 Bd6 6. O-O O-O 7. Nc3 Nc6 8. Re1 e5 9. dxe5
d5 is slightly better for White.

9... Bxe5
Nxe5 is slightly better for Black.

10. Nxe5 Nxe5 11. Be2 Qe7 12. a3 a6 13. b4 b5 14. Bb2 Be6? 15. Rc1?
White could win a pawn with Nb5 (if axb5 Bxe5 wins a knight).

15... Nc4 16. Bxc4
Probably not the best trade for White, giving away the advantage of the two bishops.

16... Bxc4 17. Ne2
Another less than stellar move for White.

17... Qe4?
This move gives White the opportunity to create a pawn weakness in front of Black's king, with Bxf6.

18. Qd4?
White decides to go for an exchange of Queens instead, but he could have waited for this on the next move.

18... Rfd8 19. Qxe4 Nxe4 20. Nd4 Nd2?
White: This move is risky & doesn't really accomplish anything.
Black: After 20. Nd4, Black is worried about the development of the Knight to the center. Knowing White won't appreciate the unwanted intruder and will move to attack as such (21. Red1), the next move 21...Nb3 trades the Knights regardless of play(barring a dropped piece).

 21. Red1 Nb3 22. Rc3?
Nxb3 is better for White, as it does not lead to an isolated pawn.

22... Nxd4 23. Rxd4 Rxd4 24. exd4 Rd8 25. Rc1 h6 26. Re1 Ra8 27. h3
White should probably take this opportunity to infiltrate Black's position with Re7, but instead plays it a bit too conservatively.

27... a5 28. Bc3 axb4 29. Bxb4 Rd8 30. Rd1
Ba5 generates some initiative.

30... Bb3 31. Rd2 Be6 32. f3
Ba5 is still called for...

32... g5 33. Kf2 h534. Ke3 Bd5 35. Rc2 c6 36. Bc5 Kg7 37. Rc1 Re8+ 38. Kd2
White is better off moving the king back to f2, in order to defend his kingside pawns.

39... f6 39. Ra1 g4 40. hxg4 hxg4 41. f4??
White played this move too quickly & hung a pawn.

41... Bxg2 42. Re1
White could try to create some counterplay with a5, but decides to offer a rook trade, thinking a draw would be the most likely result due to having opposite colored bishops.
Note: Analysis has the game in Black's favor: -3.01 

42... Rxe1 43. Kxe1 Kg6
g3 gives Black the best chance for a win.

44. Kf2 Bd5 45. Kg3 f5
With White controlling the dark squares, and Black controlling the dark squares, the position looks hopelessly drawn.

46. Bb4 *
Draw Agreed
1/2 - 1/2
