WHITE: Nigel Short
Position after 22.Ne3g4


22...Rxf1+!!

  • The exchange sacrifice gives Black a commanding advasntage on space and freedom.
  • Also good is 22...Rxg4 23.Nxg4 Qxg4 24.Qc1 e5.

23.Nxf1 Qxg4 24.Ne3 Qg6 25.Kf2?!

  • White's position has already been pounded and this move may be an attempt to shorten the agony.
  • If 25.Qa2 Qf7 then:
    • 26.0-0-0 Bd7 27.Qd2 Bb5 28.Qd4 Qc7 gives Black an overwhelming edge.
    • 26.Rh1 Qc7 27.Qd2 Bd7 28.h5 Rc8 29.Rc1 Bb5 gives Black a commanding advantage in space.

25...e5

  • For all intents and purposes, White is busted.
  • Just as good, if not a shade better, is 25...Bd7! 26.Qe1 d4 then:
    • 27.Nf1 e5 28.Rg3 Qf6+ 29.Kg1 Bc6 30.cxd4 exd4 gives Black a passer duo in the center for White to worry about.
    • If 27.cxd4? then after 27...e5 28.Rg3 Qf6+ 29.Kg1 exd4 Black is winning.

26.Rg3 Qf6+ 27.Kg1 Be6 28.Qe1 Rf8 29.Rd1 Kh8

  • Black might win quicker after29...Rd8 30.Rd2 d4 31.Rf2 Qe7 32.cxd4 exd4.

30.h5?

  • This moves the pawn beyond where it can be easily protected.
  • Although 30.Rg5 h6 31.Rh5 Nd7 32.Qe2 d4 33.Rf1 Qd8 leaves Black with a firm upper hand, it's still better than the text.


BLACK: Paco Vallejo



WHITE: Nigel Short
Position after 30.h4h5


30...Qh4!

  • White cannot cover his h-pawn.

31.c4

  • White is losing hopelessly, but chess etiquette requires that he fight on until it is obvious to everyone.
  • If 31.Nf1 Rf4 then:
    • 32.Qe3 Qxh5 33.Re1 Nc4 wins for Black.
    • If 32.Rb1 then Black wins after 32...Qxh5 33.Qe3 Nc4 34.Qa7 Qe2.
  • 31.Rh3 drops the exchange to 31...Qxe1+ 32.Rxe1 Bxh3 33.gxh3 Rf3, leaving Black two pawns to the good.

31...d4! 32.c5

  • If 32.Nd5 then 32...Nxc4! 33.Nc7 Bf5 34.Rc1 Nb2 35.Nb5 Nd3! is cruching.

32...Nc4 33.Nf1

  • If 33.Nxc4 then Black wins after 33...Bxc4 34.h6 g5 35.Rh3 Qxe1+ 36.Rxe1 e3.

33...Qxh5 34.Rc1 e3 35.b5

  • If 35.Ra1 then Black wins after 35...Rf6 36.Qd1 Qxd1 37.Rxd1 e2.

35...e4 36.Qb4 e2 37.Nh2 Qf5

  • Black wins quicker after 37...d3! 38.c6 Qe8 39.Qc3 Qe7.

38.Nf3 Qf4 39.Qe1 Qe3+ 0-1

  • If 40.Kh2 exf3 41.gxf3 Nd2 then:
    • 42.Qg1 Nxf3+ wins even more material.
    • 42.Kg2 Nxf3 43.Qg1 Nh4+ 44.Kh2 Rf2+ forces mate.
  • Mr. Short resigns.

Arkadij Naiditsch - Sergey Volkov
40th Rilton Cup, Round 7
Stockholm, 3 January 2011

Closed French Game: MacCutcheon Defense


1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5

  • The MacCutcheon Defense is rarely seen these days. White usually plays the Steinitz Opening 4.e5 followed by 6.f4. See Karjakin-Carlsen, IT A, Wijk aan Zee, 2010.

4...Bb4 5.e5 h6 6.Be3 Ne4 7.Qg4

  • So far, this is SOP.

7...Kf8

  • If 7...g6 8.a3 Bxc3+ 9.bxc3 then:
    • If 9...Nxc3 10.Bd3 Nc6 11.h4 then:
      • If 11...Ne7 12.h5 g5 then:
        • 13.Ne2 Nxe2 14.Qxe2 Nf5 15.g4 Nxe3 16.fxe3 c5 17.c3 gives Black an extra pawn, but White is better developed and holds more space (Vuckovic-Nepomniachtchi, Euro Ch, Plovdiv, 2008).
        • 13.f3 c5 14.dxc5 Nc6 15.f4 d4 16.Bd2 Qd5(Amonatov-Nepomniachtchi, Aeroflot Op, Moscow, 2008).
      • 11...Qe7 12.Nh3 Bd7 13.h5 g5 14.f4 gxf4 15.Bf2 Qf8 16.Qxf4 0-0-0 17.0-0 Ne4 18.Bh4 gives White a comfortable advantage in space and the initiative, which makes it very easy to live a pawn down (Fressinet-Vysochin, Op, Brussels, 2000).
    • If 9...c5 10.Bd3 then:
      • If 10...h5 11.Qf4 g5 12.Qf3 Nxc3 13.dxc5 d4 14.Bd2 Nc6 then:
        • If 15.Qf6 Qxf6 16.exf6 then:
          • If 16...Na4 17.Bxg5 Nxc5 18.Nf3 Nxd3+ 19.cxd3 b6 20.Rc1 Bb7 then:
            • 21.Kd2 Rd8 22.Rc2 Rd5 23.Rhc1 Kd7 is equal (Areshchenko-Smerdon, Op, Isle of Man, 2007).
            • 21.h4 Rd8 22.Ke2 Rd5 23.Rc4 Kd7 24.Rhc1 Rc8 gives Black a small advantage in space (Erdogdu-Kindermann, Euro ChT, Novi Sad, 2009).
          • 16...g4 17.Bxc3 dxc3 18.Ne2 Ne5 19.Be4 Rb8 20.h3 Kd8 21.Nxc3 gives White an extra pawn and more space (Jakovenko-Vitiugov, Russian Ch, Moscow, 2007).
        • 15.Qg3 Qd5 16.f4 gxf4 17.Bxf4 Bd7 18.Nf3 draw (Felgaer-Cubas, Ol, Calvia, 2004).
      • 10...Nxc3 11.dxc5 Nc6 12.Nf3 Qa5 13.0-0 Qa4 14.Qxa4 Nxa4 15.Bb5 Nc3 16.a4 Bd7 gives White a small advantage in space (Hracek-Vaisser, EU ChT, Pula, 1997).

8.a3 Bxc3+ 9.bxc3 Nxc3

  • Black has won a pawn, but it is not terribly significant given the closed center that give White a lasting advantage in space.

10.Bd3 Nc6

  • If 10...c5 11.dxc5 Nc6 12.Nf3 then:
    • 12...f5 13.exf6 Qxf6 14.Qh5 e5 15.Bg6 Kg8 16.0-0 Be6 17.Rae1 Bf7 gives Black the advantage in space (Klovans-Ashby, Op, Bad Zweishenahn, 2008).
    • 12...Qa5 13.0-0 Bd7 14.Rfe1 Qa4 15.Qh3 Kg8 16.Bd2 gives White the edge in space (Fressinet-Vallin, French ChT, Port Bacares, 2005).

11.Nf3

  • 11.h4 f5 12.Qf4 Ne7 13.h5 Qe8 14.g4 Qf7 15.g5 hxg5 16.Qxg5 gives White a slight advantage in space (Zhukova-Groffen, Op, Gibraltar, 2006).

11...Na4 (N)

  • 11...Ne7 12.0-0 Bd7 13.Bd2 Na4 14.Rab1 Nb6 15.h4 gives White a slight advantage in space (T. L. Petrosian-Vallejo, Euro Club Cup, Crete, 2008).

12.0-0

  • White has a good advantage in space, more than compensating for Black's extra pawn.
  • 12.Nd2 Nb2 13.Be2 Na5 14.Qg3 Nac4 15.0-0 also gives White the advantage in space.

12...Nb2 13.Be2!?

  • White retreats his good Bishop to a less effective square.
  • Better is to activate the Bishop on the queeside before Black closes that diagonal: After 13.Bb5 Nc4 14.Nd2 Nxe3 15.fxe3 Qg5 16.Qf3 White continues to enjoy enough space to enjoy and advantage in spite of Black's extra pawn.

13...Nc4! 14.Nd2

  • White does not want Black's Knight meddling in his center.
  • If 14.Bf4 Qe7 15.Bxc4 dxc4 then:
    • 16.Rfb1 Qd7 17.c3 Ne7 is equal.
    • 16.Be3 b6 17.Nd2 Bb7 18.Rfe1 Na5 19.Ne4 h5 is equal

14...Nxd2 15.Bxd2 f5

  • The game is equal.

16.exf6

  • If 16.Qf4 then:
    • If 16...Qg5! then:
      • 17.Qxg5 hxg5 18.Rfd1 g4 19.c4 dxc4 20.Bxc4 remains equal.
      • 17.Rad1 Qxf4 18.Bxf4 g5 19.Be3 f4 20.Bc1 remains equal.
    • 16...g5?! 17.Qe3! Qd7 18.Rfb1 Ke8 19.Rb3 b6 20.Qc3 gives White the advantage in space.

16...Qxf6 17.c3!?

  • 17.Bc3 Kg8 18.Bd3 e5 19.dxe5 Qxf2+ 20.Rxf2 Bxg4 remains equal.

17...e5!

  • Black assumes a slight advantage.

18.Qg3 Bf5?!

  • Black grabs some space, but his immeduate cncern should be the pawn exchange.
  • If 18...exd4 19.Rac1 then:
    • 19...dxc3 20.Bxc3 d4 21.Bd2 Bf5 22.Qxc7 is again equal.
    • 19...Qd6?! 20.Bf4! Qxa3 21.Qf3 Ke7 22.Rfe1 leaves an attack brewing around Black's King out in the open.

19.Rae1?!

  • White should play the pawn exchnange, giving his Bishop more scop in an open center.
  • If 19.dxe5 Nxe5 20.Be3 Re8 21.Bd4 Qd6 22.Rfe1 gives White much more freedom; Black centralized Knight is under heavy fire.

19...exd4 20.c4

  • 20.cxd4 then:
    • 20...Rc8 21.Bf3 Qf7 22.Bc3 Kg8 remains equal.
    • The pyrotechnical display 20...Nxd4!? 21.Qxc7! Kg8 22.Qxb7 Rd8 23.Bd1! Bd3! 24.Ba5!! gives White the advantage in space.


BLACK: Sergey Volkov



WHITE: Arkadij Naiditsch
Position after 20.c3c4


20...d3!?

  • Black destroys White's proud Bishop pair, but his gets into some difficulty in the process.
  • 20...dxc4 21.Bxc4 Rc8 22.Bd5 Rd8 23.Bxc6 Qxc6 24.Qf4 is equal.

21.Bxd3 Bxd3 22.Qxd3 d4

  • White has the advantage thanks to his developed Rooks.
  • 22...dxc4!? 23.Qxc4 Qf7 24.Qc2 Kg8 25.Bc3 h5 26.Re3 gives White the active game.

23.Re4 Kg8 24.Rf4

  • White attacks the Queen (not bad), but stronger is 24.Rb1! Rb8 25.Bf4 Qf7 26.c5 h5 27.h4 giving White a better center and more piece activity.

24...Qd6 25.Re1 Rd8

  • Black can equalize the game only be developing his Rooks. With White's Queen on d3, denying the Black King the use of h7, that isn't possible for the King's Rook.


BLACK: Sergey Volkov



WHITE: Arkadij Naiditsch
Position after 25...Ra8d8


26.c5!

  • White sacrifices a pawn for attack.
  • 26.Rfe4!? Qg6 27.Bf4 Rf8 28.Bxc7 Kh7 29.c5 Rf7! is equal.

26...Qxc5?

  • Now Black should lose.
  • If 26...Qd7 27.Qb3+ then:
    • If 27...Qd5 then:
      • 28.Re8+ Kh7 29.Qd3+ g6 30.Rf6 paints Black into a corner.
      • 28.Qxb7!? Kh7 29.Rfe4 Rhf8! 30.Qxc7 Rd7 31.Qg3 gives White only a small advantage as Black's piece protect each other.
    • 27...Kh7 28.Rf7 Qd5 29.Qd3+ wins for White.

27.Qg6 Qg5 28.Rf8+?!

  • Black misses the winning line.
  • 28.Re8+ Rxe8 29.Qxe8+ Kh7 30.Qxh8+!! Kxh8 31.Rf8+ wins for White.

28...Kxf8 29.Bxg5 hxg5 30.Qf5+

  • White's two pieces, especialy the Queen, are still more active than Black's three.
  • 30.Re6 Rh6 31.Qf5+ Kg8 32.Rxh6 gxh6 33.Qg6+ gives White a vastly superior game, but in order tom win he still needs a passed pawn.

30...Kg8 31.f4!

  • Also good is 31.Qb5! Rh6 32.Qxb7 d3 33.Rd1 d2 34.f3 gives White a great advantage.
  • Not as good is 31.Qxg5?! Rh6! 32.Qb5 b6 33.Qc4+ Kf8 34.Qd3 Rf6 with equality.

31...g4

  • No better is taking the pawn.
  • If 31...gxf4!? then:
    • 32.Qxf4 Rh5 33.Qxc7 Rb5 34.a4! Rf5 35.Re7 gives White a great advantage.
    • 32.Qe6+ Kf8 33.Re4 Rh6 34.Rxf4+ forces Black to play the Rook to f6, after which White wins a pawn.

32.Qe6+!?

  • White misses another chance to put the game away.
  • 32.Qb5! Rb8 33.Qd5+ Kf8 34.Qd7 Rh5 35.Qxc7 leaves White on the verge of winning.

32...Kf8 33.Qf5+ Kg8 34.Rb1!?

  • White goes pawn hunting, but the only pawn he should worry about is the one at d4.
  • 34.Qb5 Rb8 35.Qd5+ Kf8 36.Qf5+ Kg8 37.Qxg4 maintains White's superior position.


BLACK: Sergey Volkov



WHITE: Arkadij Naiditsch
Position after 34.Rd1b1


34...d3!

  • This is an example of a Rook, Knight and pawn are equal to a Queen in the endgame. White's Rook is compelled to return to d1 and blockade duty.

35.Rd1 Nd4 36.Qe4

  • 36.Qxd3!? Nf3+ 37.Qxf3 gxf3 38.Rxd8+ Kh7 39.Rd7 Rc8 nets Black an extra pawn, but White has more freedom.

36...Ne2+ 37.Kf2 Nxf4 38.Qc4+ Kh7 39.g3 Nh3+!?

  • This move is not the strongest Black can make here. After the King sidessteps the check, he will consolidate his position.
  • If 39...b5! then:
    • 40.Qxb5! Rd5 41.Qc4 Nh3+ remains equal.
    • If 40.Qe4+?! results in a sudden reversal by 40...Ng6! 41.Qxg4 Kh6 42.Rc1 Rd5 when:
      • 43.Rc6 Rf8+ 44.Kg1 Rf6 45.Qh3+ Kg5! gives Black the advantage in space.
      • 43.Rxc7? Rf8+ 44.Kg2 d2! wins for Black.

40.Kg2 Rhf8

  • If 40...Rde8?! 41.Qxd3+! then:
    • 41...Kh6 42.Qc4 Ng5 43.Rd5 leaves White enjoying a strong initiative.
    • 41...Kg8?? allows mate: 42.Qd5+ Kh7 43.Qh5+ Kg8 44.Qxe8+ Kh7 45.Qh5+ Kg8 46.Rd8#.

41.Qxg4!

  • White keeps the advantage, for now.
  • 41.Qe4+ Kh6 42.Qxg4 Ng5 43.Qh4+ Kg6 44.Qc4 Rfe8 is equal.

41...Nf2 42.Qh4+ Kg8 43.Qc4+!

  • Well played by White.
  • If 43.Rd2!? (the "obvious" move) 43...Rd5! 44.Qb4 c6 then:
    • 45.Qb1! Ne4 46.Rxd3 Rf2+ 47.Kg1 Nd2 48.Qa2 is equal.
    • 45.Qxb7!? Ng4! 46.Qxa7 c5 47.Kg1 Ne3! leave Black with the advantage thanks to his command of the f-file cobines with the Knight attacking f1.

43...Kh8 44.Rd2!

  • A passed pawn is a criminal who must be kept under lock and key. --Nimzovich.

44...Rd7

BLACK: Sergey Volkov



WHITE: Arkadij Naiditsch
Position after 44...Rd8d7


45.Qb4!?

  • The attempt by White to win a piece with 45.Rxf2?? loses the game to 45...Rxf2+ 46.Kxf2 d2! when ther is nothing to stop the pawn.
  • Nevertheless, the correct move is 45.Qh4+! Kg8 46.Qb4 Rdf7 47.Qxb7 when White continues to hold a small advantage in space.

45...Rdf7

  • The game is equal.

46.Qxb7 c5 47.Qd5

  • More accurate is 47.Qc6 (putting the Queen behind the weaker c-pawn) 47...Rf5 48.h3 R8f7 49.g4 Rf4 50.Qxc5 when the game remans equal.

47...Rf5 48.Qc4 R8f6 49.Rb2 Kh7 50.Rb8?

  • By this time, Grandelius had long since won his game from Maceija, meaning that Herr Naiditsch would have to win in order to remain tied for first. Unfortunately, the position is about as dead a draw as there can be given the number of pieces still left on the board and does not justify aggression by either side. White should play to blockade and capture the d-pawn.
  • If 50.Rd2 g5 51.h3 Rf7 52.Qe6 Kg7 53.Qe3 remains equal.


BLACK: Sergey Volkov



WHITE: Arkadij Naiditsch
Position after 50.Rb2b8


50...d2!

  • White can no longer blockade the d-pawn.

51.Qg8+

  • It's already too late to go after the d-pawn.
  • If 51.Rd8 then Black wins after 51...d1Q 52.Rxd1 Nxd1 53.Qh4+ Kg8 54.Qe4 Nf2.

51...Kg6 52.Qe8+ Rf7 53.g4

  • 53.Rd8 d1Q 54.Rxd1 still fails against 54...Nxd1 55.Qe1 when:
    • Black wins easily after 55...Rf2+! 56.Kg1 Rf1+ 57.Qxf1 Rxf1+ 58.Kxf1 Nb2.
    • 55...Rf1?! 56.Qe4+! R7f5 57.g4 Ne3+ 58.Qxe3 puts White back in the fight for a draw.

53...R5f6 54.Qe5 Nxg4 55.Qe4+

  • White is under the illusion -- or the spell of a false hope -- that he can draw with perpetual check.

55...Rf5 56.Rd8 Nf2 57.Rd6+ R7f6 58.Rxf6+

  • White can no longer prevent the d-pawn from queening.
  • If 58.Qe8+ Kh7 59.Rxd2 Rg5+ 60.Kf1 then:
    • 60...Nd3+ 61.Ke2 Re5+ 62.Qxe5 Nxe5 leaves Black winning with an extra piece.
    • 60...Ne4+ 61.Ke2 Rg2+ 62.Ke3 Nxd2 isn't as good, but it's still good enough.


BLACK: Sergey Volkov



WHITE: Arkadij Naiditsch
Position after 58.Rd6f6+:R


58...Kxf6 59.Qc6+ Kg5 60.Kg3 d1Q 61.h4+ Kh5 62.Qe8+ Kh6 0-1

  • If 63.Qh8+ Kg6 then White is out of checks.
  • Herr Naiditsch resigns.

BLACK: Aleksandr Shimanov



WHITE: Nils Grandelius
Position after 16...Qd8c8


17.d5!

    • 25.Be2 Ra5 26.Rd2 Rca8 27.Ne6 remains equal.

23.Bb2 Na6?!

  • Black does not appear ready to exchange Knights, although the Black Knight is unimportant and White's Knight rests on an outpost in the center.
  • If 23...Nc6 24.Nxc6 Rxc6 25.Rxd5 Rc2 26.Bd4 Be8 is equal.

24.Bb5 Be8

  • As a result of his strategic inaccuracy on the previous move, Black continues to suffer.
  • If 24...Bf7 25.Bc6 Rab8 26.Bxd5 Bxd5 then:
    • 27.Nf5! Bf8 28.Rxd5 Rc2 29.Bd4 Kf7 30.Rd7+ Ke8 gives White a splendid initiative.

25.Nf5 Bf8

  • White controls the dark squares on the Bishop's diagonal except for c5, where the Bishop blocks the Rook's command of the c-file. All of that considered, the retreat is best.
  • 25...Bc5!? 26.Bxe8! Rxe8 then:
    • 27.Rxd5 g6 28.Nd4! leaves White with all of his vital points covered.
    • 27.Rd2? Bf8! 28.Ne2 Bc6 29.f5 Nc5 30.Nf4 Nd3 wins for Black.

26.Bxe8 Rxe8 27.Rxd5

  • White has an extra pawn.

27...Nc5

  • The text is better than 27...Nc7 28.Rd4 Ra5 29.Kf2 when:
    • 29...h5 30.h3 Rea8 31.Rd2 Ne6 32.Bd4 hxg4 33.hxg4 gives White the advantage in space.
    • 29...Na6 30.Ng3 Nc5 31.Rd2 Nd3+ 32.Ke2 Nxb2 33.Rxb2 gives White the advantage in space

28.Bd4

BLACK: Aleksandr Shimanov



WHITE: Nils Grandelius
Position after 28.Bb2d4


28...Nd3!?

  • The battle begins in earnest. This move is a shade too aggressive.
  • Better is the more restrained 28...Ne6! 29.Kf1 Rac8 30.h4 Rc2 31.h5 Ra8 32.Rd7 with equality.

29.Rd7!?

  • While this looks impressive, Black is already holding on to the g7 square. Consequently, the move weakens White's defenses without giving him any real possibility of attack.
  • 29.Ng3! Rac8 30.Rd1 Nc1 31.Rd2 Ra8 32.Rd7 gives White acres of space.
  • 29.Rb5?! Rac8 30.Rb7 Rc2! 31.h4 g6 32.Ng3 is equal.

29...Rac8 30.Rf1?

  • White leaves the a-pawn unguarded. This is not recommended.
  • Much better is 30.h4! Rc6 31.Kg2 Rc2+ 32.Kh3 Ra8 when White still has the advantage in space.

30...Rc2 31.g5

  • This advance is premature; a White3 pawn at g5 will need another defender.
  • Better is 31.Ra7! Rd8 32.h4 Rd5 when:
    • 33.Rxg7+!! Bxg7 34.Ne7+ Kf7 35.Nxd5 leaves White two pawns to the good.
    • 33.Ra8 Kf7 34.h5 Rd7 35.Ra6 Kg8 36.Ng3 gives White nothing more than a slight.

31...hxg5!

  • Black deals with the g-pawn directly. The alternative is not as good.
  • If 31...Ra8!? 32.a4 bxa3 33.gxh6 gxh6 then:
    • 34.Kh1 Nf2+ 35.Kg2 Ng4+ 36.Kg3 Nxh2 is equal.
    • 34.Ng3? takes pressure off the g7 square and allows Black to play 34...Bc5! and now if 35.Nxe4 then Black wins after 35...Bxd4 36.exd4 Ra6 .

32.fxg5 Ra8!

  • Black takes advantage of the White Rook's absence from a1 to double team White's a-pawn.

33.Ra1?

  • White closes the barn door after the cows have escaped.
  • If 33.a4 bxa3 34.gxf6 gxf6 then:
    • 35.Kh1 Nf2+ 36.Kg2 Ra5 37.Rxf2 Rxf2+ 38.Kxf2 Rxf5+ leaves Black enjoying an enormous initiative.
    • 35.Ng3? Ne5! 36.Bxe5 fxe5 37.Nxe4 Bg7 38.Kh1 a2 it will cost White a Rook to stop Blackl's a-pawn.


BLACK: Aleksandr Shimanov



WHITE: Nils Grandelius
Position after 33.Rf1a1


33...Ra5!

  • Black wins by sending White's pieces to inefective squares.
  • If 33...fxg5? then 34.Bxg7! Nc5 35.Rc7 Bxg7 36.Rxg7+ gives White the edge in space.
34.Ng3 Rxg5 35.Rf1 Rg4

    35...Rxa2 36.Kh1 Rg4 37.Rg1 Nf2+ 38.Kg2 Rh4 wins for Black.

36.Kh1

    36.Ra1 the Black wins by 36...f5 37.Kh1 Rh4 38.Nf1 g5 39.Rd5 Nf2+ when the end is slow and painful.

36...Rh4

  • Upon seing this move, White could have resigned.

37.Kg1

  • White cannot prevent mate.
  • If 37.Nxe4 then 37...Rhxh2+ 38.Kg1 Rcg2# .

37...Rhxh2 38.Nxe4 Rcg2# 0-1

    • 12...Qa5 13.Kb1 Bb7 14.a3 0-0-0 15.Be2 Kb8 16.Bh5 Rhf8 17.Bg4 gives White a good advantage in space (Wunnick-Sayed, Op, Amsterdam, 2005).

12...d5 13.Be2

  • 13.Kb1 Bd7 14.Qe3 f5 15.Ne2 Qc7 16.Ng3 Rc8 17.Bd3 is equal (Berg-Dreev, Euro Ch, Budva, 2009).

13...Bb7 (N)

  • 13...Rg8 14.Kb1 b4 15.exf6 Bxf6 16.Qxb4 Bd7 17.Nxd5 exd5 18.Rhe1 Be7 gives Black a small advantage in space (Barreto-Diamante, Brazilian Ch, Porto Alegre, 2008).

14.f5

  • The game is equal.
  • 14.Bh5! Qc7 15.Rhe1 f5 16.Ne2 Rg8 17.Bf3 Rc8 is equal.

14...fxe5 15.Qxe5 Bf6 16.Qg3 Qb8 17.Qh3!?

  • The Queen is more effective at g3, where it prevents Black from castling or moving his Rook to g8, than it is at its new post.
  • 17.fxe6 Qxg3 18.exf7+ Kxf7 19.hxg3 Bxc3 20.bxc3 Rac8 is equal.
  • If 17.Qf3 0-0 18.Rhe1 Kh8 then:
    • 19.g3 Qc7 20.Qd3 Bxc3 21.Qxc3+ Qxc3 22.bxc3 e5 gives Black the advantage with a strong central pawn duo.
    • If 19.Qg4 then:

      • If 19...Qxh2?? then 20.Rh1! leaves Black defenseless on the h-file.

17...d4?!

  • Black weaken his center.
  • If 17...b4 18.Na4 then:
    • If 18...Bc6 19.Nc5 then:
      • 19...e5! 20.Qh6 Ke7 21.g4 e4 22.Nb3 Qg8 is equal.
      • 19...Qd6 20.fxe6 Qxc5 21.exf7+ Kxf7 22.Rhf1 Ba4 23.b3 gives White better King safety, the initiative and more space.

    • 18...Qc7?! 19.fxe6 0-0 20.Rhf1 fxe6 21.Qxe6+ Kg7 22.Bd3 gives White an extra pawn and a clear advantage in space.

18.fxe6?

  • This is the logical follow up of White's 17th move, but he assumes Black would play 18...dxc3and leaves White with insufficient command of the center.
  • If 18.Nb1 Qe5 19.Bf3 d3 20.c3 then:
    • 20...Qf4+ 21.Nd2 Bxf3 22.Qxf3 Qxf3 23.Nxf3 0-0-0 gives Black a small advantage in space.

BLACK: Romain Edouard



WHITE: Deep Sengupta
Position after 18.fe6:p


18...Qf4+!!

  • That nature abhors a vacuum applies to chess as much as to astrophysics. Black takes over the center that White has vacated. The consequences of failing to fill the vacuum are dire.
  • If 18...dxc3? 19.exf7+! then:
    • If 19...Kf8 20.Qh6+ Bg7 21.Qb6 Qf4+ 22.Kb1 then:
      • If 22...Bf6 23.Qxb7 Qb4 then:
        • If 24.b3!! Qa3 25.Qxa8+ then:
          • If 25...Kg7 26.Qxh8+ Kxh8 27.f8Q+ Qxf8 28.Ka1 gives Whit two Rook and a pawn over a Queen.
          • 25...Kxf7? gets really ugly after 26.Rd7+! when:
            • If 26...Qe7 then White wins after 27.Rxe7+ Bxe7 28.Qxh8.
            • 26...Kg6 27.Qe4+ Kh6 28.Qe3+ Kg6 29.Bd3+ Kh5 30.Rd5+ Kh4 31.Qg3#.
        • 24.Qxa8+ Kg7 25.f8Q+ Rxf8 26.Rd7+ Kh8 gives Black the advantage; he can mate White befgore White can mate Black.
      • 22...Qb4? 23.Rd8+! Rxd8 24.Qxd8+ Kxf7 25.Bh5+ Ke6 26.Qb6+.
    • 19...Kxf7 20.Rd7+ Kf8 21.Qh6+ Ke8 22.Rhd1 leaves the Black King in a mating net.

19.Kb1 dxc3 20.exf7+

  • Black has a piece for two pawns.

20...Kf8 21.a3

  • If 21.b3 Qg5 22.Rhe1 then:
    • 22...Bxg2 23.Qe6 Qe5 24.Qxe5 Bxe5 25.Bh5 Bxh2 is equal.
    • If 22...Kg7 23.f8Q+ Raxf8 24.Rd7+ wins for White.

21...h5!?

  • Black takes some of the wind out of his own sails.
  • If 21...Qg5 22.Rhe1 Bc8 23.Qf3 Ra7 24.Rd5 Qh4 25.g3 Qh6 is equal.
  • 22.Bf3 Bc8! (Attacking the Queen so that the Rook is safe and to take advantage of the Queen's momentary lack of freedom) 23.g4 Ra7 24.Rd5 Qf4 gives Black a strong position and a material advantage.

22.Rhf1 Qe5 23.Bd3

  • White apparently intends to move the Bishop to g6, but never gets the opportunity. White probably underestimates the strength of Black's reply.
  • If 23.Rde1 Rd8 24.Bf3 Bc8 then:
    • 25.Rxe5 Bxh3 26.Re8+ Rxe8 27.fxe8Q+ Kxe8 28.gxh3 cxb2 is equal.
    • If 25.Qg3? then Black wins after 25...Qxg3! 26.hxg3 Kxf7.


BLACK: Romain Edouard



WHITE: Deep Sengupta
Position after 23.Be2d3


23...Qg5!

  • Black wins a pawn and prevents 24.Bg6.

24.Qd7 Bxg2 25.Rde1 Be7

  • No better is 25...Be5 26.Rf5 Qd8 27.Qxd8+ Rxd8 28.Rexe5.

26.Rf5 Qh4 27.Rfe5 Rd8

  • Black skewers the Bishop through the Queen, but all this accomplishes is the return of sacrificed material before resignation.

28.Qc7 Rxd3 29.cxd3 1-0

  • M. Edouard resigns.

9.b3

  • The game is equal.

9...Nc6!?

  • Of course, Black must not neglect his queenside development, but the masked attack on the c-pawn from the Bishop at f4 makes this a somewhat poor move at this point.
  • 9...b5 10.h3 a5 11.e3 f6 12.Ng4 h5 13.Nh2 remains equal.


BLACK: Sundar Shyam



WHITE: Mark Hebden
Position after 9...Nb8c6


10.Nxc6!?

  • White fails to pick up on the opportunity, although this is the right idea.
  • If 10.Qc3! (attacking the Knight and skewering the c-pawn) 10...Qd6! (covering the c-pawn and attacking White's e-pawn) then:

      • 11...Nb4 12.Qb2 Nd5 13.Bg3 Qe6 14.h4 h5 15.c4 gives White the advantage in space.
  • 11.Nxc6?! is still premature as after 11...Qxf4+! 12.e3 when:
    • 12...Qf6! 13.Ne5 Qxf2 it's Black who wins a pawn.
    • 12...Qxf2?! 13.Nxe7+! Kh8 14.Nxc8 Raxc8 is equal.

10...Qxc6

  • The game is equal.

11.e3

  • 16.fxe4 a4 17.b4 Qxe4 18.Qxb5 e5 remains equal.

  • This is played with the idea of blocking Black' heavy pioeces from using the c-file, but it allows Black to creat a target in White's e-pawn.

    • 19.Be5 Bxe5 20.dxe5 exf3 21.gxf3 a4 is equal.
    • 19.Bg3?! exf3 20.Qxf3 Qxf3 21.gxf3 Rxe3 gives Black a clear advantange.

17...exf3!

  • Black takes advantage of the Bishop being on a bad square and breaks up White's kingside pawns.
