The Game of the Century

The Game of the Century refers to a chess game played between chessmaster Donald Byrne and 13-year old Bobby Fischer in the Rosenwald Memorial Tournament in New York on October 17, 1956. It was nicknamed "The Game of the Century" by Hans Kmoch in Chess Review.

In this game, Fischer (playing black) demonstrates brilliance, innovation, improvisation and poetry. Byrne (playing white), after a standard opening, makes a minor mistake on move 11, moving the same piece twice (wasting time). Fischer pounces, with strong sacrificial play, culminating in an incredible queen sacrifice on move 17. Byrne captures the queen, but Fischer more than compensates by taking many other pieces. The ending is an excellent demonstration of pieces working together to achieve a checkmate.

Burgess suggests 3 lessons to be learned from this game, which can be summarized as follows:

* In general, don't waste time by moving the same piece twice in an opening; get your other pieces developed first.
* Material sacrifices are likely to be effective if your opponent's king is still in the middle and a central file is open.
* Even at 13, Fischer was a player to be reckoned with.

Donald Byrne (1930-1976), by the time of this game, had already obtained first place in the 1953 US Open Championship, and would eventually represent the United States in three Olympiads (1962, 1964, and 1968). Robert "Bobby" Fischer (1943-) eventually became world champion in 1972.

The game is given here in algebraic notation:



1. Nf3

A noncommittal move. From here, the game can develop into a number of different openings.

1. ... Nf6 2. c4 g6 3. Nc3 Bg7

Fischer has opted for a defense based on "hypermodern" principles: he's inviting Byrne to establish a classical pawn stronghold in the center, which Fischer hopes to undermine and transform into a target. Fischer has fianchettoed his bishop, so it can attack the a1-h8 diagonal including its center squares.

4. d4 O-O

Fischer castles, concentrating on protecting his king immediately.

5. Bf4 d5

This introduces the Gr?feld Defence, an opening usually brought about with the opening moves 1.d4 Nf6 2.c4 g6 3.Nc3 d5.

6. Qb3

The so-called Russian System, putting pressure on Fischer's central d5 pawn.

6. ...dxc4

Fischer relinquishes his centre, but draws Byrne's queen to a square where it is a little exposed and can be attacked.

7. Qxc4 c6 8. e4 Nbd7 9. Rd1 Nb6 10. Qc5 Bg4

At this point, Byrne's pieces are more developed, and he controls the center squares. However, Fischer's king is well-protected, while Byrne's king is not.

11. Bg5?

Here Byrne makes a mistake - he moves the same piece twice, losing time, instead of developing in some way. Both [Burgess, Nunn and Emms] and [Wade and O'Connell] suggest 11. Be2; this would protect the King and enable a later kingside castle. For example, the game Flear-Morris, Dublin 1991, continued 11. Be2 Nfd7 12. Qa3 Bxf3 13. Bxf3 e5 14. dxe5 Qe8 15. Be2 Nxe5 16. O-O and white is better.

11. ... Na4!!

Here Fischer cleverly offers up his Knight, but if Byrne takes it with Nxa4 Fischer will play Nxe4, and Byrne then suddenly has some terrible choices:

13. Qxe7 Qa5+ 14. b4 Qxa4 15. Qxe4 Rfe8 16. Be7 Bxf3 17. gxf3 Bf8 produces a terrible pin.
13. Bxe7 Nxc5 14. Bxd8 Nxa4 15. Bg5 Bxf3 16. gxf3 Nxb2 gives Fischer an extra pawn and ruin's Byrne's pawn structure.
13. Qc1 Qa5+ Nc3 Bxf3 15.gxf3 Nxg5 gives Fischer back his piece and a better position.

12. Qa3 Nxc3 13. bxc3 Nxe4!

Fischer offers to Byrne material, in exchange for a much better position that is especially dangerous to white: an open e-file, with white's king poorly protected.

14. Bxe7

Byrne wisely decides to decline the offered material.

14. ... Qb6 15. Bc4 Nxc3! 16. Bc5 Rfe8+ 17. Kf1 Be6!!

This is a very clever move by Fischer; this is the move that made this game famous. Instead of trying to protect his queen, Fischer viciously counter-attacks using his bishop and sacrifices his queen. Byrne cannot simply take the bishop, because that will lead to checkmate:
18. Bxe6 Qb5+ 19. Kg1 Ne2+ 20. Kf1 Ng3+ 21. Kg1 Qf1+ 22. Rxf1 Ne2#

18. Bxb6

Byrne takes Fischer's offered queen, which leads to a massive loss of material, but other moves are no better. For example, 18.Bxe6 leads to a forced smothered mate with 18...Qb5+ 19.Kg1 Ne2+ 20.Kf1 Ng3+ 21.Kg1 Qf1+ 22.Rxf1 Ne2#.

18. ... Bxc4+

Fischer now begins a series of discovered checks, picking up material.

19. Kg1 Ne2+ 20. Kf1 Nxd4+ 21. Kg1 Ne2+ 22. Kf1 Nc3+ 23. Kg1 axb6

This move by Fischer takes time out to capture a piece, but it doesn't waste time because it also threatens Byrne's queen. Byrne's queen cannot take the knight on c3, because it's protected by Fischer's bishop on g7.

24. Qb4 Ra4

Fischer uses his pieces together nicely in concert; the knight on c3 protects the rook on a4, which in turn protects the bishop on c4. This forces Byrne's queen away.

25. Qxb6

Byrne's queen picks up a pawn, but it's now poorly placed.

25. ... Nxd1

Fischer has taken a rook, 2 bishops, and a pawn as compensation for his queen; in short, Fischer has gained significantly more material than he's lost. In addition, Byrne's remaining rook is stuck on h1 and it will take precious time to free it, giving Fischer opportunity to set up another offensive. White has the only remaining queen, but this will not be enough.

26. h3 Rxa2 27. Kh2 Nxf2 28. Re1 Rxe1 29. Qd8+ Bf8 30. Nxe1 Bd5 31. Nf3 Ne4 32. Qb8 b5 33. h4 h5 34. Ne5 Kg7

Fischer breaks the pin, allowing the bishop to attack as well.

35. Kg1 Bc5+

Now Fischer "peels away" the white king from his last defender, and begins a series of checks that culminate in checkmate. This series of moves is extremely interesting in the way Fischer shows how to use various pieces together to force a checkmate.

36. Kf1 Ng3+

Adjacent bishops can, without opposition, simply move next to each other to force the king along. However, Fischer can't do this here and simply move his light-square bishop to c4, because Byrne's knight protects c4. However, the knight does the job, forcing Byrne's king along.

37. Ke1 Bb4+ 38. Kd1 Bb3+ 39. Kc1 Ne2+ 40. Kb1 Nc3+ 41. Kc1 Rc2# 0-1

Friendly Match between Kastam KL & XUIA

Setelah hampir dua tahun setengah aku tak main chess, baru-baru ni (17hb Jun 2009) kawan-kawan lama aku ajak aku untuk join diaorang dalam Friendly Match antara Kastam KL dan XUIA. Ketuan pemain Kastam KL adalah bekas coach kami di UIA dulu iaitu Rizal Ahmad Kamal.
Barisan pemain yang menjayakan Friendly Match tersebut ialah seperti berikut:
Team Kastam:
1. Rizal Ahmad Kamal
2. Rosli
3. Haji Idris
4. Azizan
Team XUIA:
1. Hanif Arkurni Abas
2. Fattah
3. Rezal
4. Termizi
Permainan diadakan di perkarangan surau Kompleks Kediaman Pegawai Kastam Kelana Jaya lebih kurang bermula pada pukul 9.45 malam. Setelah dibuat undian, pemain pertama bagi XUIA diundi untuk bermain buah hitam. Maknanya, sebagai pemain keempat, aku bermain buah putih.
Keputusan permainan adalah memihak kepada XUIA dengan kemenganan 3-1. Hanya Rizal Ahmad Kamal berjaya mempertahankan maruah Kastam dengan mencapai kemenangan ke atas Hanif Arkurni. Permainan Sicilian Dragon Rizal masih berbisa yang mana Hanif telah banyak kehilangan tempo bermain hitam. Analisis secara detail ada diberikan oleh Rizal dalam blognya di sini.
Walaupun dah hampir 2 tahun setengah aku tak pegang buah catur, aku cuba bermain sebaik mungkin. Di bawah adalah permainan aku dengan checkmate pada gerakan ke 16.

1. e4 g6 2.d4 Bg7 3.Nf3 d6 4.Nc3 Nf6 5.Bc4 0-0 6.0-0 Nbd7
Sekiranya 6.... Nxe4 untuk memerangkap putih dengan cara 'fork' apabila 7.Nxe4 d5, putih boleh sacrifice bishop terlebih dahulu sebelum makan kuda di petak e4 dengan cara 7.Bxf7+ Rxf7 8.Nxe4
7.Qe2
Untuk memberi ruang pada Rook untuk parking pada petak d1. Aku tak ada idea sangat pada masa ni, cuma susun buah ala-ala serangan Morra Gambit.
7..... h6
Untuk menghalang kuda putih daripada diletakkan pada petak g5 dan seterusnya menyerang petak f7. Gerakan ini telah sedikit sebanyak melemahkan pertahanan hitam dan perlu diingat pawn pada petak g6 sekarang sudah tidak dikawal kerana pawn pada petak f7 sudah lama dipin oleh bishop putih pada petak c4.
8.Rd1
Tanpa berfikir panjang, aku meneruskan agenda Rd1. Gerakan yang lebih baik ialah 8.e5 dan kemungkinan permainan akan diteruskan begini 8.... dxe5 9.dxe5 Ng4 10.e6 Nde5 11.Rd1 Qe8 12.exf7+ Nxf7 13.Nd5 mengancam untuk Nxc7 fork antara Rook dan Queen.
8..... Qe8 9.e5 dxe5
Sekiranya hitam menggerakkan kuda f6nya pada petak h7 atau h5, ini membolehkan putih menggerakkan kudanya pada petak d5 untuk mengancam fork pada petak c7.
10.dxe5 Ng4 11.e6
Gerakan alternatif bagi putih ialah 11.Bf4 bagi menjaga pawn e5 dan seterusnya attack kuda hitam pada petak g4 dengan 12.h3. Kuda hitam pada petak g4 dah tak ada tempat nak lari.
11..... Nde5 12.exf7+ Nxf7
Jika 12.... Rxf7, permainan mungkin diteruskan begini; 13.Bxf7+ Qxf7 14.Nxe5 Nxe5 15.Bxh6 Nf3+ 16.gxf3 Bxh6 17.Rd8+ Kh7 advantage pada putih.
13.Nh4
Serangan alternatif ialah 13.Nd5 target pada pawn c7. Jika hitam defence dengan 13..... Qc6, putih main 14.Nxe7+.
13..... Kh7
Untuk mengawal pawn g6, kononnya... Gerakan yang lebih baik bagi hitam ialah 13..... Bxc3 untuk menghapuskan kuda putih yang merupakan salah satu penyerang yang baik dalam posisi sekarang dan kemudian 14..... Kg7.




Aku yang memang sukakan gerakan sacrifice, tanpa berfikir panjang, aku telah membuat keputusan untuk sacrifice kuda pada petak g6.

14.Nxg6 Kxg6

Jika 14..... Kg8 15.Nd5, variation 1) 15..... Bf5 16.Ndxe7+ Kh7 17.Nxf8+ Qxf8+ 18.Nxf5. Variation 2) 15..... Kh7 16.Qd3 advantage pada putih.

15.Bd3+

Jangan 15.Qd3+ sebab hitam boleh defence 15..... Bf5

15..... Kf6??

Blunder dalam keadaan yang sukar. Gerakan yang lebih baik ialah 15..... Kh5 16.h3 Nfe5 advantage pastinya untuk putih.

16.Nd5# Checkmate. Jarang dapat checkmate lawan dalam mana-mana tournament.

1-0

The Grand Asian Chess Challenge V; Dalam Kenangan

Dalam membelek nota-nota lama, aku terjumpa nota permainan semasa Tournament Grand Asian Chess Challenge V pada tahun 2000 yang lalu. Ada satu game yang aku rasa agak menarik untuk dikongsi bersama.

Tidak sia-sia aku berlatih The Smith-Morra Gambit, rupa-rupanya ada juga 'mangsa' aku pada tournament tersebut. Berikut adalah game pada pusingan ke empat menggunakan Morra Gambit.



Pada gerakan ke 14, selepas hitam menggerakkan kuda pada petak ...Ne8, ada gerakan force mate in 7. Masa tournament manalah nampak benda-benda macam ni, tapi lepas analisis barulah jumpalah. Position selepas gerakan ke 14 adalah seperti berikut:



Nampak tak force mate in 7?

Jawapannya:

[15. Nd5+ Ke6 16.Nxe5 g6 (16...dxe5 17.Qh3+ Kd6 18.Nf6+ Ke7 19.Rxd7+ Kxf6 20.Qf5#; 16...Nxe5 17.Qh3+ Ng4 18.Qxg4+ Ke5 19.Bd4#) 17.Qh3+ f5 18.Qh4 fxe4 (18...g5 19.exf5+ Kxf5 20.Qg4+ Kxe5 21.Re1#) 19.Qh3+ Kxe5 20.f4+ exf3+ 21.Re1#]

Enjoy the game!
