Nigel Short In Sole First So Far At Corus (Group B)

The 71st Corus Tournament is presently going on. It is usually divided into three groups. In Group B, at the time of this post, Nigel Short is thus far solely in first place. Here is one of his wins from the tournament:

Dimitri Reinderman vs Nigel Short
Corus (Group B) 2009
Spanish Game: Exchange. Gligoric Variation

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Bxc6 dxc6 5. O-O f6 6. d4 Bg4 7. c3 Bd6 8. Be3 Ne7 9. dxe5 fxe5 10. c4 c5 11. b4 b6 12. bxc5 bxc5 13. Nbd2 O-O 14. Qa4 Ng6 15. Kh1 Qe7 16. Ne1 Nf4 17. f3 Bd7 18. Qa5 Rf6 19. Rf2 Rh6 20. Nf1 g5 21. g4 Rh3 22. Ng3 h5 23. gxh5 Rf8 24. Qd2 Qf7 25. Rc1 Be6 26. Bxf4 exf4 27. Nf5 Bxf5 28. exf5 Qxf5 29. Nd3 g4 30. Qe2 g3 31. Rg2 Qxh5 32. Qe6+ Kg7 33. Rcc2


Position after White's 33rd move



The actual game continued: 33 ... Re8 34. Qd5 Qxd5 35. cxd5 Re3 36. Nf2 Re1+ 37. Rg1 Rxh2+ 0-1. A stronger 33rd move for Black is 33...Qxf3 and play could then go 34.Ne1 Rxh2+ 35.Kg1 Rh1+ 36.Kxh1 Qf1+ 37.Rg1 Rh8+ and mate to follow.

From A Game I Played

A game I played, playing White, against a program, set at one of the lower levels, went: 1. e4 c6 2. d4 d5 3. e5 Bf5 4. c4 e6 5. Nc3 Ne7 6. Nf3 Bg4 7. h3 Bxf3 8. Qxf3 dxc4 9. Be3 Nd5 10. Bxc4 Bb4 11. 0-0 Nxc3 12. bxc3 Bxc3 13. Rab1 Qc7 14. Rfc1 Ba5 15. Qg4 Kf8 16. Rb2 Nd7 17. Rcb1 Bb6 18. Bd2 Rd8 19. a4 Rb8 20. a5 Bxa5 21. Bxa5 Qxa5 22. Rxb7 Rxb7 23. Rxb7

I think the resulting position is interesting. I am a pawn down, but have an advanatge in space and time. According to the computer evaluations, the position actually is winning for White:

Lopsided Opening Results Part Three

Some posts ago I presented two examples from the opening in which one side as a lopsided score against the other, that is, one side won twice as many games as the other side. Here is another example, arising from Alekhine's Defense:

1. e4 Nf6 2. e5 Nd5 3. d4 d6 4. c4 Nb6 5. exd6 exd6 6. Nc3 Be7 7. h3 Bf5 8. Nf3 0-0

The game database of chessbase.com has 116 games starting with the above line. From my manual count, which is fallible though, White won 50 times, and Black won 21 times.

Great Game by Aronian

Besides the Chess World Championship, the Euro Clup Cup is also going on, which has a large number of participants, including some of the top grandmasters. The following game, Aronian vs Volokitin, was played in Euro Clup Cup. It is probably one of Aronian's best games. It went:

1. d4 d5 2. c4 c6 3. Nc3 Nf6 4. e3 g6 5. Nf3 Bg7 6. h3 O-O 7. Bd3 Be6 8. Ng5 Bf5 9. Bxf5 gxf5 10. Qb3 Qb6 11. Qc2 e6 12. g4 h6 13. Nf3 fxg4 14. hxg4 Nxg4 15. e4 dxc4 16. e5 Nd7 17. Be3 f5 18. O-O-O c5 19. d5 f4 20. Ng5 hxg5 21. Qh7+ Kf7 22. Ne4 exd5 23. e6+ Kxe6 24. Qxg7 Ngf6 25. Bxc5 Nxc5 26. Nxc5+ Qxc5

Position after Black's 26th move


This position is like a chess problem: there is a mate to be had. The game continued: 27. Rde1+ Kf5 28. Rh5 Nxh5 29. Re5+ Kg4 30. Qxg5+ Kf3 31. Qxh5+ Kxf2 32. Qe2+ 1-0








World Championship Match Game 3

The third game of the Championship Match was brilliantly won by Anand, playing Black. The game started: 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 e6 5.e3 Nbd7 6.Bd3 dxc4 7.Bxc4 b5 8.Bd3 a6 9.e4 c5 10.e5 cxd4 11.Nxb5 axb5 12.exf6 gxf6 13.O-O Qb6 14.Qe2 Bb7 15.Bxb5 Bd6 16.Rd1 Rg8 17.g3 Rg4 18.Bf4 Bxf4 19.Nxd4 h5 20.Nxe6 fxe6 21.Rxd7 Kf8 22.Qd3 Rg7 23.Rxg7 Kxg7 24.gxf4

Position after White's 25th move


Notice at this point Anand is down two pawns. From what I have heard, computers gave Kramnik some advantage here, but this might be one of rare cases where computers mis-evaluated a position. Anand proceeded to win: Rd8 25.Qe2 Kh6 26.Kf1 Rg8 27.a4 Bg2+ 28.Ke1 Bh3 29.Ra3 Rg1+ 30.Kd2 Qd4+ 31.Kc2 Bg4 32.f3 Bf5+ 33.Bd3 Bh3 34.a5 Rg2 35.a6 Rxe2+ 36.Bxe2 Bf5+ 37.Kb3 Qe3+ 38.Ka2 Qxe2 39.a7 Qc4+ 40.Ka1 Qf1+ 41.Ka2 Bb1+ 0-1




World Championship Match 2nd Game

The second game of the championship match ended in a draw:

White: Anand Black: Kramnik
1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. f3 d5 5. a3 Bxc3+ 6. bxc3 c5 7. cxd5 Nxd5 8. dxc5 f5 9. Qc2 Nd7 10. e4 fxe4 11. fxe4 N5f6 12. c6 bxc6 13. Nf3 Qa5 14. Bd2 Ba6 15. c4 Qc5 16. Bd3 Ng4 17. Bb4 Qe3+ 18.

World Championship Match 1st Game

The first game in the World Championship Match 2008 between Anand and Kramnik ended in a draw. Kramnik played White, Anand played Black.


1.d4 d5 2.c4 c6 3.Nc3 Nf6 4.cxd5 cxd5 5.Bf4 Nc6 6.e3 Bf5 7.Nf3 e6 8.Qb3 Bb4 9.Bb5 O-O 10.Bxc6 Bxc3+ 11.Qxc3 Rc8 12.Ne5 Ng4 13.Nxg4 Bxg4 14.Qb4 Rxc6 15.Qxb7 Qc8 16.Qxc8 Rfxc8 17.O-O a5 18.f3 Bf5 19.Rfe1 Bg6 20.b3 f6 21.e4 dxe4 22.fxe4 Rd8 23.Rad1 Rc2 24.e5 fxe5 25.Bxe5 Rxa2 26.Ra1 Rxa1 27.Rxa1 Rd5 28.Rc1 Rd7 29.Rc5 Ra7 30.Rc7 Rxc7 31.Bxc7 Bc2 32.Bxa5 Bxb3 1/2-1/2

Svidler Still In First

Svidler is still in first place in the Russian Superfinal Tournament. However, he might not be if one of his opponents found a winning move. The game between Peter Svidler and Nikita Vitiugov went: 1. d4 d5 2. Nf3 Nf6 3. c4 c6 4. Nc3 a6 5. e3 e6 6. c5 b6 7. cxb6 Nbd7 8. Bd3 c5 9. b3 Nxb6 10. O-O Bb7 11. Bb2 cxd4 12. exd4 Be7 13. Rc1 O-O 14. Qe2 a5 15. a4 Nc8 16. Ne5 Na7 17. Nb5 Nxb5 18. Bxb5 Qb6 19. Rc2 Rfc8 20. Rfc1 Rxc2 21. Rxc2 Bd6 22. Qe1 Qd8 23. Qc1 Qe7 24. Bc3 h6 25. h3 Ne4 26. Be1 Qd8 27. Nd7 Ra7 28. Ne5 Ra8 29. Nd3 Qe7 30. f3 Ng3 31. Bxg3 Bxg3 32. f4 Ba6 33. Bxa6 Rxa6 34. Rc8+ Kh7 35. Rc7 Qf6 36. Qe3 Bh4 37. Ne5 Qf5 38. Rxf7 Qe4 39. Qc3

Position after White's 39th move


Here, Vitiugov missed the winning move 39. ... Rc6!. This was mentioned at chessgames.com--I cannot stop praising that site--see http://www.chessgames.com/perl/chessgame?gid=1508855 for analysis.




Zappa vs. Rybka Game

Here is a game between Zappa and Rybka, arguably the two strongest chess playing programs, which occurred this year.

The game started: 1. e4 c5 2. Nc3 Nc6 3. Nge2 Nf6 4. d4 cxd4 5. Nxd4 d6 6. Bg5 e6 7. Qd2 a6 8. O-O-O Bd7 9. f3 b5 10. Nxc6 Bxc6 11. Bd3 Be7 12. Kb1 O-O 13. h4 Rc8 14. a3 Ba8 15. Qe3 Re8 16. Qa7

Diagram after White's 16th move


And here Rybka sacrifices the rook 16. ... Rxc3, an idea seen in Sicilian games. The game continued: 17. bxc3 Qc8 18. a4 Qxc3 19. axb5 axb5 20. Bd2 Qc6 21. Ba5 d5 22. e5 Nd7 23. Qc7 Bc5 24.

Svidler In Lead

In the Russian Superfinals, Peter Svidler so far is in first place, with three wins in three games. One of his games, against Ernesto Inarkiev, went:

1. d4 d5 2. c4 c6 3. Nc3 Nf6 4. e3 e6 5. Nf3 Nbd7 6. Bd3 dxc4 7. Bxc4 b5 8. Bd3 Bd6 9. O-O O-O 10. e4 e5 11. Ne2 a6 12. b3 Re8 13. Bb2 Bb7 14. Rc1 exd4 15. Nexd4 c5 16. Nf5 Bf8 17. e5 Ng4 18. Nd6 Bxf3 19. Qxf3 Ngxe5

Position after Black's 19th move



Then Svidler played 20 Bxh7+ and the game went: Kxh7 21. Qf5+ Kg8 22. Nxe8 Qxe8 23. Rce1 g6 24. Qe4 Bg7 25. f4 Rb8 26. Qd5 Rb6 27. fxe5 Re6 28. Rd1 Nxe5 29. Qxc5 Nf3+ 30. Rxf3 Bxb2 31. Qd5 Bf6 32.

New England Masters Game

A game between Parker Bi Guang Zhao and Leonid Kritz in the New England Masters Tournamet went: 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 d6 6. Bg5 e6 7. Qd2 a6 8. O-O-O h6 9. Nxc6 bxc6 10. Bf4 d5 11. Qe3 Bb4 12. a3 Ba5 13. Be2 O-O 14. exd5 cxd5 15. Qg3 Kh8 16. Be5 Ne8 17. f4 Bc7 18. Bd3 Bxe5 19. fxe5 a5 20. h4 Qb6 21. Rdf1 Rb8

Position after Black's 21st move


And here Parker Bi Guang Zhao played 22. Qg6! In order to avoid mate, Black eventually has to give up material. The game went: 22. ... Qe3+ 23. Kd1 fxg6 24. Rxf8+ Kh7 25. h5 Qxd3+ 26. cxd3 Bd7 27. hxg6+ Kxg6 28. Kc2 Rc8 29. d4 Kg5 30. Rhf1 g6 31. R1f7 Bc6 32. Re7 1-0

Three Move Problem IV

This is problem XXXVIII from the book, composed by A. C. Challenger. White to mate in 3:



Solution: 1. Qb8 Kxd5 2. Nd4 exd2 3. Qb5 mate





Three Move Problem III

The chess problem here is number XXXVII from the book, and was composed by Dr. Lasker.



White moves 1. Qh1 There are various ways Black can play but they all lose. One example is 1 ... e4 2. Rxb7 Bb5 3. Qe1 mate





Three Move Problem II

This second problem is number XXXVI from the book, composed by W. F. von Holzhausen.



Computer checked solution: 1. Qa8 e4 2. Qa1 exf3 3. Qd4 mate




Three Move Problem I


The three move problem above is from the previously mentioned book "Three Move Problems." I've been to the Newberry Library a few times before. Some of their older works are dated in knowledge; for example I came across a book on astronomy written in the context of Newtonian physics; others works seem simply to be barking up the wrong tree, such as on witchcraft. But older books on chess positions seem to hold up well, perhaps because chess problems are more like mathematics. The problem above is number XXXV from the book, created by Sam Loyd.
Here is a computer checked solution: 1. Kd2 Qc4 2. Bg4+ Nxg4 3. Rh5 mate





Older Chess Books from the Newberry Library

This weekend I went to the Newberry Library in Chicago. The Newberry Library is a private, non-circulating library, but it is free and open to the public. It has a collection of older and rare materials, such as maps and books hundreds of years old.
I came across a book entitled "Three Move Problems" by F. Baird. It seems to have been published in 1913. In this post I will present an extract from the book; in other posts I plan to present chess problems from the book.

From Chapter II METHODS OF SOLVING:
"The following methods of solving three-move problems are the only ones which need to be considered:--
1. Perceiving the theme instantaneously, or determining the author's idea by deduction.
2. Allowing Black to make the first move, and then treating the problem as a two-mover, the final process being the finding of the key-move.
3. Allowing Black to make the first move, and then making two moves for White in succession, followed by another for Black, and a third for White.
4. Experimenting with various likely and plausible key-moves until the correct one is found. This method, although adopted by the majority of beginners, is not calculated to give the solver the same amount of satisfaction as the other methods, and it is not to be recommended except with some problems containing only a few pieces. For instance, when dealing with the Rex solus type of composition, such a course might yield quicker results.
5. The exhuastive process before mentioned, wherby every move that it is possible for White to make must be tried. This method, although lengthy, is the one which must be employed for solution tourneys which are other than continuous."

Lopsided Opening Results, Part II

Here is a line that can arise from the Slav: 1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. Nc3 a6 5. c5 g6 6. h3 Bg7 7. Bf4 O-O 8. e3



In chesslab's historical database of games from 1485-1990, only one game is given with this opening, and it ended in a draw. In its database from 1991-present, it gives 58 games, with White winning 56%, Black winning 12%, and Draws 32%




Lopsided Opening Results

In this post and perhaps others I will present opening lines which: 1) have been played at least in 20 games and 2) where one side had at least twice as many wins as losses.

Here is a position arising from the Grunfeld: 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. Nf3 Bg7 5. Bg5 Ne4 6. cxd5 Nxg5 7. Nxg5 e6 8. Nf3 exd5 9. e3 a5 10. Be2 O-O 11. O-O c6




Chesslabs.com says it has a database of 2 million games, and has the feature 'position stats.'
In its historical archive of games from 1485-1990, it gives: White won 0%, Black won 21%, Draw 79%. In the games played from 1991-present, it gives: White won 8%, Black won 43%, Draw 49%
