The JR Chess Report (January 31): Magnus Wins in Wijk
Magnus Survives Loss to Kramnik, Wins Wijk



Norwegian grandmaster Magnus Carlsen survived a ninth-round defeat at the hands of former world champion Vladimir Kramnik of Russia to win the Group A competition at the Dutch North Sea resort of Wijk ann Zee, which completed earlier today.

The result put Kramnik in first place after nine rounds, where he remained until reigning world champion Vishy Anand defeated him in yesterday's twelfth round. Meanwhile, Magnus, showing the character of a champion, simply dusted himself off and won his next two games to recapture first place yesterday.

Most games in Group A were drawn today, with the only decisive outcome being reigning US national champion Hikaru Nakamura over two-time Dutch national champion Sergei Tiviakov. By winning the game, Nakamura finished tied for fourth with Anand.

To win the event, Magnus scored 8½ points (+5 -1 =7) to finsish a half-point ahead of Kramnik and Latvian-born Spanish grandmaster Alexei Shirov, who began the tournament by winning five games in a row but made little impact afterward.

Group B was won by Dutch national champion Anish Giri, 15, with 9 points, a half-point point over Latvian-born German grandmaster Arkadij Naiditsch.

Chinese grandmaster Li Chao won Group C handily with 10 points, a point and a half ahead of former world junior champion Abhijeet Gupta of India. Fifteen-year-old American GM Ray Robson, who lead in the early going, finished tied for fifth with 7½ points.



Gibraltar Underway; Four-Way Tie for First after Six



The eighth annual Gibtelecom Masters' Open began in Gibraltar Tuesday at the Caleta Hotel on The Rock.

After six rounds, four players are tied for first place with 5 points each. They are: grandmaster Mickey Adams of Britain; German GM Jan Gustafsson; Chandra Sandipan of India; and Ukrainian WGM Natalia Zhukova, the wife of reigning Russian national champion Alexander Grischuk.

In tomorrow's pairings, Ms. Zhukova will have White against Adams and Sandipan will play White against Gufstaffson.

The ten round tournament concludes Thursday. The games begin at 3 pm local time (6 am PST) and live games will be broadcast on the Official Tournament Website.



Moscow Open Begins



The annual Moscow open began yesterday with 187 participants in the main tournament and 140 in the women's tournament.

Neither the main nor the women's tournament feature last year's winners, US grandmaster Alex Onischuk and Russian WGM Natalia Pogonina. Natalia Andreevna started the Russian women's championship tournament in December and had to dop out after seven rounds due to illness.

After two rounds, 20 palyers have perfect scores including top seeded Russian GM Alexander Motylev and fifteen-year-old Chinese GM Hou Yifan, making her return to international chess after an absense of several weeks. In the women's tournament, 28 players have won both their games including the top seed, Chinese WGM Ju Wenjun and German IM Elisabeth Pähtz.

The Moscow Open is a nine-round Swiss System event running through next Sunday. The top boards of the main and women's tournament are broadast live at the official tournament website beginning at 4 pm local time (5 am PST).

Position after 17.c3c4


17...e3!?

  • The pawn sacrifice throws White's pieces into disorder.

18.Nd3!

  • Declining the proffered pawn, at least for now, keeps some semblance of order in White's game.
  • 18.Bxe3 f4 19.Bd2 Bf5 20.Nd3 Qc7 21.g4 Bg6 remains equal.

18...Nc6

  • Black sees he must develop his queenside.
  • 18...f4!? 19.Ba3 Rf5 20.g4 Rf7 21.Ne5 Rc7 22.Qg6 gives White the initiative and an impressive advantage in space in spite of being virtually a piece down due to the entombed light bound Bishop.

19.Bxe3!

  • White finally takes the pawn and assures himself of the advantage.

19...Nxd4 20.Bxd4 Bxd4+

  • Black has the momentary advantage in space.

21.Kh1

  • Space, however, is a fluid thing.
  • White can turn matters around with 21.Nf2! Be3 22.cxd5! (opening a line for the Queen) 22...f4 23.d6 giving White an extra pawn that is running up the board.

21...f4!?

  • Black drops the d-pawn.
  • If 21...dxc4 then:
    • 22.Ne5 Qf6 23.Rxd4 Qxe5 24.Rxc4 f4 25.g4 gives White the initiative, but Black has a queenside majority and can use that after weathering the present storm.
    • White stands better after 22.Nc5 Qf6 23.Qxc4 Bxc5 24.Qxc5 Re8 25.e4, but Black can use his queenside majority in an attempt to whip up counterplay.

22.Rb5!

  • White wins a pawn at least temporarily.

22...Qf6?

  • It will do Black little good to protect the pawn.
  • 22...Be6? 23.Nxf4!! gxf4 24.Rxd4 fxg3 25.cxd5 Qf6 26.Rxb7 wins for White.
  • 22...dxc4 23.Nxf4 gxf4 24.Qxc4 fxg3 25.Rxd4 Qf6 26.hxg3 gives White an extra pawn.
  • Black's best bet appears to be the path of least resistance: 22...fxg3 23.Rxd5 Qf6 24.hxg3 Be6 25.Rd6 Rad8 26.c5 gives White the active game, but Black can get his pawn back and gain some counterplay after 26...Rxd6 27.cxd6 Rd8 28.Qc7 Bb6

23...Be6

  • 23...fxg3 24.hxg3 Be6 25.Rd6 Rad8 26.c5 Rxd6 27.cxd6 White remains a pawn to the good.

24.Nxf4 gxf4 25.R5xd4 fxg3 26.hxg3

  • White emerges with two extra pawns.

26...Rg8 27.Rf4 Qg5 28.Rh4 Rg6 29.Qc3+ Kh7

  • Being two pawns down, it only makes matters worse to exchange Queens in order to relieve pressure.

WHITE: Robin Swinkels
Position after 18...Nd6f7


19.Nc4

19...Bf8!?

  • If Black's idea is to provoke White into allowing him greater activity, then this is a good way to go aboout it.
  • Objectively better is 19...Nxc4 20.dxc4 Rxd1+ 21.Rxd1 Bxa3 22.Nxa4 Nd6 when Black still has the initiative.

20.Nxb6

  • This is exactly what Black wanted.
  • 20.Be4 f5 21.Bg2 Bxc4 22.dxc4 Bxa3 gives Black an extra pawn.

20...cxb6!

  • White's pawn structure is spoiled, but Black's heavy pieces now find themselves on open files.

21.Qc1 Bg4 22.f3 Bf5 23.e4!?

  • White throws the Black Bishop in the briar patch by forcing him to go to an open diagonal.
  • 23.Bf1 Qe6 24.Bb2 Bc5 25.Kh1 Bg6 26.Ne4 Rac8 gives Black a small advantage in space.

  • The text move has the virtue for White of not letting his position get worse.
  • 27.f4 Nxb5 28.fxe5 Nxc3 29.Qxc3 Qxc3 30.Bxc3 Bxa3 gives Black an extra pawn.

27...Rac8 28.Qe1!?

  • White ignores the threat to his d-pawn.
  • 28.Bh3 Rc7 29.Kg2 Be7 30.Re2 g6 31.f4 then:
    • 31...Nf7 32.Qd2 Qd6 33.Rc1 Kg7 34.Bg4 Rc5 Black wins the pawn at d3.
    • 31.Nd5!? Bxd5 32.exd5 Qxc1 33.Bxc1 Nf5! Black wins the pawn at d5.

  • White tries to pressure Black's kingside, but the plan is already half-refuted by the proctection Black already affords the g-pawn.

7. Nakamura - Shirov, Round 7
Alexei Shirov started at Wijk aan Zee with five consecutive wins, but scored -2 the rest of the way. Still, this was good enough to tie for second place.

Reigning US national champion Hikaru Nakamura, making his debut at Wijk aan Zee, finished with 7½ points (+4 -2 =7) and demonstrated that he has earned the right to play in elite events.

In the following game, Naka knocked el señor Shirov out of first place. The two fiery competitors did not disappoint their fans, who were expecting a real fight.

18...Rg8!

  • Black is building a combination in the g-file.

  • This isn't the best way to meet the combination.
  • 19.Nd5 Nh3+ 20.gxh3 Be4+ 21.Bg4 Bxd5 22.Qxd5 remains equal.

19...Nh3+?!

  • Black has set up a discovered pin in the g-file, but can't find the best way to make use of it.
  • Better is 19...Bd3! 20.Nd5 Qxb2 21.Nxf4 Bxf1 when:
    • 22.Rb1 Bxg2 23.Bxg2 Qxa2 24.Nd5 Kf8 gives Black the material advantage, but White has some initiative in compensation.
    • 22.Nd5!? Bd3! 23.Nc7+ Ke7 24.Nxa8 Rxa8 gives Black an extra pawn.

20.Kh1

  • The Knight is taboo.

  • 22...Rd8? drops a pawn to 23.Qa4+! Kf8 24.Qh4 Rb8 25.Bxa6.

23.Re2 Qb6 24.Bd5!

  • White blocks the central pawns.
  • If 24.Bf3 f5 25.Qa4+ Kf8 26.Bd5 then:
    • 26...Rg7 27.Rf1 f4 28.Rd2 Bf7 29.Bxf7 Rxf7 30.Qe4 gives White the initiative against Black's pawn chain, but Black has defensive resources to keep the d-pawn protected and potential counterpaly in the b-file.
    • 26...Bf7 27.Bxf7 Kxf7 28.Qd7+ Kf6 29.Rf1 f4 30.Ref2 gives White a clear advantage; the Black King isn't "stalemated," but if it had to move it would be to the inhospitable g-file.

24...Rg7

  • The Rook doesn't look very happy at g7.
  • If 24...Bh5 then White easily breaks the pin by 25.Qf1 Rf8 26.Rd2.

25.Qd2 f5

  • The pawn advance makes sense of Black's claustrophobic Rook move.

26.Rf1 Kd7 27.b4 f4!?

  • Black has a pawn chain, but White has already rendered it immobile.
  • 27...a5 28.Rb1 then:
    • If

        • If 33...Qxb5 then after 34.Qxd6+ Kb7 35.Rxe5 Black is crushed.
      • 31...Qxb5 32.Bf3 Qc5 33.Bxh5 Rb3 34.Qd3 Kc7 35.Qf5 White has an extra piece.
    • If 28...f4 then after 29.Rb3 axb4 30.Rxb4 Qa7 31.Bf3 Rxb4 32.cxb4 White has restrained Black's pawn chain.

28.a4 a5?

  • It seems a little harsh to award this move a query, but Black never recovers from the effects of this inaccuracy, which allows White a passed pawn.
  • If 28...Re7 29.a5 Qb5 30.Rd1 then:
    • If 30...e4 31.Bc4 Qe5 32.Bxa6 e3 33.Qd4 then:
      • 33...Qxd4 34.Rxd4 Bh5 35.Rxf4 Bxe2 36.Bxe2 d5 37.Rd4 when each side must stop the other's pawn mass. White has the advantage with a larger pawn mass, which is more difficult to stop, and a pawn majority on the kingside.
      • 33...Bh5? 34.Qa7+! Ke6 35.Qxb8 Bxe2 36.Bxe2 leaves White up by a piece.
    • 30...Kc7 31.Be4 Re6 32.Bf3 Rf6 33.Ree1 gives White a stronger blaockade of White's central pawns than Black has against White's queenside.

Position after 28...a6a5


29.b5!

  • White passes his b-pawn, forcing Black to expend energy blocking it.

29...Rd8

  • Black's plan is to use the King as the blockader on the queenside; the Rook will cover the base of the pawn chanin for now.
  • If 29...Kc8 30.c4 Rc7 31.Bc6 Qc5 32.Qc3 then:
    • 32...Rxc6!? 33.bxc6 Qxc6 34.c5 Rb4 35.Qh3+ Kd8 36.cxd6 gives White the exchange.
    • If 32...Qb4 33.Qh3+ Kd8 34.Qh4+ Kc8 then the exchange sacrifice 35.Rxf4!! assures that White will put a Rook on Black's back rank.

30.g3

  • White nibbles at Black's pawn chain.
  • Perhaps White would do better to strengthen his b-pawn and paly on the queenside: 30.c4 Bh5 31.Ree1 Bg4 32.Qc3 Rf8 33.Bc6+.

30...fxg3 31.hxg3 Kc8 32.c4 Kb8 33.Rf6!

  • White directly attacks the base of Black's pawn chain and threatens to win a pawn by 34,Rxe5!.

    • 34...Kc8 35.Rf6 Re7 36.Rb2 Qb6 37.Rd2 threatens the powerful 38.c5!.
    • 34...Re8? 35.b6! Qc5 36.Rb2 Qd4 37.Qxa5 is an easy win for White.

33...Re7 34.Kh2 e4

  • If 34...Bh5 35.c5 Qc7 36.Ref2 then:
    • 36...e4 37.cxd6 Rxd6 38.Rxd6 Qxd6 39.Qxa5 Qxd5 40.Rd2 is lights out.
    • If 36...dxc5 then White casts a mating net around the Black King with 37.Ra6! Qc8 38.Ra8+ Kc7 39.b6+ Kd7 40.Bc4+.

8.Nc3 e6

  • This resembles an Open Sicilian with the Moroczy Opening opposed to the Scheveningen-Najdorf Defense, except that BLack has activated his Queen's Bishop.

9.Be3 Nf6 10.Nd2 Be7 11.h3 e5

  • 11...Bh5 12.f4 Bg6 13.0-0 Qc7 14.f5 gives White the advantage in space and more activity.

  • 13...Bh5 14.Rc1 Rc8 15.0-0 Rc6 16.Be3 Bd8 is equal.

15.cxd5 Bd8 16.Bxd8 Kxd8 17.Rc1

  • The palyers have competed development with White having the more active game.

17...b5 18.Ke2

  • Better is 21...h6 22.b3 Nh5 23.g3 f5 24.a3 g6 25.h4 with equality.

28.Nd3!?

  • White should restrain Black's kingside before taking further action in the center. The text allows Black to equalize.
  • If 28.g4 g6 29.Nd3 then:
    • 29...Ne7 30.Rc3 f5 31.gxf5 gxf5 32.f3 h5 33.Nb4 White still has the advantage in space.
    • 29...f5?! 30.gxf5 gxf5 31.Nb4 Ne7 32.Rxa6 White has an extra pawn.

28...Ne7 29.Rc3 f5

  • This is the better of two ways to advance Black's kingside; this also undermines White's center.
  • 29...h5 30.Nb4 Ra8 31.g4 then:
    • 31...h4 32.Kd2 Ng6 33.Nd3 Rc8 34.Rxc8 Kxc8 35.b4 puts Black under restraint, but White's is also limited.
    • Not quite the same and not quite as good is 31...g6!? 32.Rf3 hxg4 33.hxg4 Rc8 34.b3 gives White a clear advantage with pressure on the f-pawn.

30.f3 f4 31.Kf2!?

  • The game is now equal.
  • White wants to restrain Black's entire position (.e., give him a few pawn moves as possible). She has the right moves but puts them in the wrong order.
  • Correct is 31.Nb4 Ra8 32.h4 h6 33.Kf2 g5 34.h5 when Black's only unblocked pawn is the g-pawn, which would be taken if it were to advance.

31...Ra8 32.h4 g6 33.g3 fxg3+ 34.Kxg3 g5?

  • Black's kingside pawns were fine as they were. It will take White two move to bring his Rook to the kingside to support any advance by the White pawns, giving Black time for something else.
  • If 34...Rb8 then White continues to enjoy the advantage in space after 35.Nb4 Ra8 36.f4 exf4+ 37.Kxf4.

36...h6 37.gxh6 Rg1 38.Rc1 Rg6

  • If 38...Ng6+ 39.Kh5 then:
    • 39...Rg3 40.h7 Nh8 41.Rc6 White passes his a-pawn, snapping Black's defense in half.
    • 39...Nf4+ drops a piece to 40.Nxf4 exf4 41.Rxg1.

39.f4 Rxh6+ 40.Kg3 exf4+ 41.Nxf4 Ng6

  • 41...Rh8 42.Ne6 Rg8+ 43.Kf4 Ng6+ 44.Kf5 leaves Black little hope.

42.Ne6 Ke7 43.Nd4 Kf6 44.Nf5 Rh5 45.Rc8

  • A little better is 45.Rc6 Rg5+ 46.Kf2 Nf4 47.Rxa6.

      • 15.Qd2 Bb5 16.Rfb1 Ba6 leaves Black a pawn to the good.
    • 10.Nxc6 bxc6 11.Bxe4 dxe4 12.Qxd8+ Kxd8 13.Re1 f6 14.Rxe4 Kc7 15.Be3 e5 gives Black healthier pawns (Gutiérrez-Jussupow, Capablanca Mem, Cienfuegos, 1979).

11.Qd3

  • The game is equal.

11...Qc7!?

    • 14...Qf6 15.Bxf8 Kxf8 16.d6 Ke8 17.Rd1 Kd7 18.Qxh7 gives White a clear advantage.

      • 20.Rfe1?! Nxf3+ 21.Qxf3 Bb7 gives Black the initiative and an attakck on the long diagonal and g-file.
    • 18.Qf3? Bb7! 19.Qh3 Rxg2+ 20.Qxg2 Bxg2 21.Kxg2 Nxc2 wins the exchange for Black.

  • 20...Ne5 21.Bf4 Bb7 22.Bxh7 Nf3+ 23.gxf3 Rxh7 24.Qxf6+ gives White two extra pawns, but otherwise his pawn structure is a disaster and Black has plenty of chances to play on the pawn weaknesses..

21.f4!

  • Of course, with his Rooks ready to roll, White opens the center.

21...Bb7

  • 21...Ba6 22.fxe5 fxe5 23.Bg5! Raf8 24.Bf6+ also wins for White.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5

  • 4.d3 Bc5 (the Guicco Pianisimo) is the way the Italian Royal Game is usually handled nowadays.

  • If 6.d3 h6 7.Nf3 e4 8.Qe2 Nxc4 9.dxc4 Bc5 then:
    • If 10.Nfd2 0-0 11.Nb3 then:
      • 11...Bg4 12.Qf1 Bb4+ 13.c3 Be7 14.h3 Bh5 15.g4 Bg6 16.Be3 Nd7 17.N1d2 Ne5 18.0-0-0 Nd3+ 19.Kb1 Bg5 20.Nd4 Qf6 gives White an extra pawn and Black the advantage in space (Bogolyubov-Elikases, Match, Munich, 1939).
      • 11...Bd6 12.Nc3 Re8 13.h3 Bb4 14.0-0 Bxc3 15.bxc3 c6 16.dxc6 bxc6 17.Be3 Nh7 18.Rad1 Qh4 19.f4 Bxh3 20.Rd6 Bg4 21.Qf2 Qxf2+ 22.Kxf2 is equal (Chigorin-Teichmann, IT, Nuremberg, 1896).

6...c6 7.dxc6 bxc6 8.Qf3

  • The text move was first played after World War II.
  • The old main line, which is just a lot of good fun, is 8.Be2 h6 when:
    • If 9.Nf3 e4 10.Ne5 Bd6 11.f4 then:
      • If 11...exf3 12.Nxf3 0-0 then:

            • If 16...Re8 17.d5 Rb8 18.a3 then:

              • 18...Ng4 19.h3 Ne3 20.Bxe3 Rxe3 21.Rb1 Qe7 22.Qd2 Bf4 23.Qd1 is equal (Estrin-Levenfish, Soviet Ch ½-final, Leningrad, 1949).

          • 14.Nc3 Nc6 15.Kh1 Re8 16.d3 Rb8 17.Qe1 Nd4 18.Nxd4 cxd4 19.Ne4 Nxe4 20.dxe4 Rxe4 gives Black the advantage in space and a more active game (Paoli-Bisguier, Norristown, 1973).
      • If 11...Qc7 then:
        • If 12.0-0 0-0 13.Nc3 Bxe5 14.fxe5 Qxe5 15.d4 exd3 16.Qxd3 then:

    • If 9.Nh3 Bc5 10.d3 0-0 11.0-0 then:
      • 11...Nb7 12.Nc3 Bb6 13.Kh1 Nc5 14.f4 e4 15.Nf2 exd3 16.Nxd3 Bf5 gives White an extra pawn and Black more space (Hamann-Geller, Kislovodsk, 1966).

8...Be7

  • If 8...Rb8 9.Bd3 h6 10.Ne4 Nd5 then:
    • If 11.b3 g6 12.Qg3 Bg7 13.Bb2 Nf4 14.Qxf4!! exf4 15.Bxg7 Kd7 16.Bf6 Qe8 17.0-0 then:

      • 17...Qf8 18.Be2 Qb4 19.Bg4+ Kc7 20.Be5+ Kd8 21.Nd6 gives White more than enough compensation of the Queen.
    • 11.Ng3 g6 12.b3 h5 13.0-0 Bg7 14.Ba3 Bg4 15.Qe4 f5 16.Qe1 gives White an extra pawn and Black more space (Honfi-Zagorovsky, Budapest, 1964).

9.Bd3

  • The obvious problem with this move is that it blocks the advance of White's d-pawn, which in turn makes it difficult to develop White's queenside. However, the Bishop at d3 can come in useful, as one can tell from a judicious study of the notes to Black's ninth move.
  • If 9.Bxc6+ Nxc6 10.Qxc6+ Bd7 then:
    • 11.Qf3 0-0 12.Nc3 Rc8 13.d3 Bc6 14.Qh3 Bd7 15.Qg3 Nh5 16.Qxe5 Bf6 17.Qd5 gives White the advantage in space and three extra pawns (Mamedyarov-Tomashevsky, Aeroflot Op, Moscow, 2009).
    • 11.Qc4 0-0 12.Nc3 Rc8 13.Qe2 Bg4 14.f3 Nh5 15.Nge4 Nf4 16.Qf1 gives White two extra pawns (Burn-von Bardeleben, IT, London, 1895).

9...h6

  • 9...0-0 10.0-0 h6 11.Ne4 Nd5 12.Ng3 Nb4 13.Nf5 Bg5 14.Re1 Nxd3 15.cxd3 Qf6 16.Ng3 Qxf3 17.gxf3 gives Black fewer pawn weaknesses (although neither side's pawn structure is anything to write home about) and White is still badly underdeveloped (Kaidanov-Onischuk, US Ch, Tulsa, 2008).

10.Ne4 Nd5 11.c3!?

  • 11.Ng3 0-0 12.Bf5 Bg5 13.0-0 Bb7 14.Ne4 g6 15.Nxg5 hxg5 16.Be4 f5 and we have a split decision: Fritz says "+/- 1.19"; JR says "Black has the advantage in space and, although he has an extra pawn, White lags in development" (Tayer-Ni Hua, Op, Edmonton, 2009).

11...0-0!?

  • The game is equal.
  • 11...h5! 12.b4 Bxb4 13.Qg3 0-0 14.0-0 Be7 15.Qxe5 gives White an extra pawn, but she is still having difficulties developing her queenside.

12.Ng3 f5!?

  • Black, with the advantage in space, proffers a pawn to take advantage of White's lack of development.

13.Bxf5?!

  • White misses a continuation that would put her in full command.
  • 13.Nxf5! Bg5 14.Be4 Bxf5 15.Bxf5 g6 16.Be6+ gives White two extra pawns.

13...Nf4?!

  • Black, in his turn, misses a chance to equalize.
  • 13...Bh4! 14.b4 Bxg3 15.Qxg3 Bxf5 16.bxa5 Nf4 White's two extra pawns don't count for much with when the Queen is her only developed piece.

14.Bc2!

  • Now the d-pawn may advance and White may continue her development normally.
  • The immediate 14.d4? proves premature after 14...Bxf5 15.Nxf5 Rxf5 16.g3 Qd5 17.Qxd5+ Nxd5 when White has only two pawns for a Knight.

14...Ba6

  • If 14...Bg5 then after 15.b3 Bb7 16.Ba3 c5 17.Ne4 Rf7 18.h4 White can use her initiative to scatter Black's pieces to the four winds.

15.Nf5 Rxf5 16.Bxf5 Nd3+?

  • This move looks strong, but is woefully inadequate.
  • Better is 16...Be2! 17.Qxe2 Nxe2 18.Kxe2 Qd5 19.f3 giving White a material advantage equivalent to a pawn, but Black can fight on with reasonable chances.

17.Kd1!

  • The text move is good, but better is 17.Bxd3! Bxd3 18.b4 e4 19.Qg4 Nc4 20.Qe6+ when White continues to hold an impressive material advantage.

17...Qd6 18.b4 e4 19.Bxe4 Rf8

  • 19...Nc4 20.Bxd3 Ne5 21.Bh7+ Kxh7 22.Qe4+ wins easily for White.

Position after 19...Ra8f8


20.Bxd3!!

  • White has a material advantage equivalent to a Rook and, in spite of her neglected development, feels she can sacrifice her Queen.

20...Rxf3 21.Bxa6 Rxf2 22.bxa5

  • In spite of surrendering her Queen, White still has a huge material advantage.

22...Qd5 23.Re1 Bd6 24.Kc2!?

  • White wins faster after 24.Re8+! Kh7 25.g4 Rxh2 26.Kc2 g6 27.Bd3.

24...Rxg2 25.Bd3 Rxh2 26.Re8+

  • 26.a6 Rf2 27.Re4 Qa5 28.Bb2 Rf4 29.Re8+ may be better.

26...Kf7 27.Re4 Qxa5 28.Na3

  • At last, White gets her queenside pieces out.
  • Better is 28.Bc4+ Kf8 29.Re6 Qf5+ 30.Kb3 Rh1 31.Na3 when White remains active.

28...Bxa3

  • Black might consider 28...Rh1 which might present White with more problems.
  • If 28...Rh1 then:
    • If 29.Nc4! Qa4+ 30.Kb1 then:
      • 30...Ba3 31.Nxa3 Qxa3 32.Kc2 Rxc1+ 33.Rxc1 Qxa2+ 34.Kd1 White should win.
      • If 30...Qb5+ 31.Nb2 Qg5 32.Kc2 Rh4 33.Nc4 White still has a material advantage and a more active game.
    • If 29.Bc4+!? Kf8 30.Re6 Be7 31.Bb3 Qf5+ 32.Kb2 puts Black back in the game with counterplay.

29.Bxa3 g5??

  • Black now loses quickly.
