Shambavi shines at the English Chess Championships

Shambavi shines at the English Chess Championships

Oxford City’s Shambavi Hariharan competed in the women’s championship (10 players).

This was a tough 7-round affair featuring some of the best players in England, such as GMs Michael Adams, Gawain Maroroa Jones, Nikita Vitiugov, and WGM Elmira Mirzoeva. In such august company our fortunes were bound to be mixed but overall we did remarkably well.

The full results and games can be found here.

Shambavi was the undisputed star of the Oxford show, sharing first prize in the English Women’s Championship with Elmira Mirzoeva on 4½/7, defeating the reigning champion in their individual encounter.

In some events that result would have been sufficient to crown her as the new titleholder, but the tournament’s rules prescribed a play-off of two rapid games. In an exciting finish followed by thousands of online chess fans, Elmira just edged it 1½–½.

A remarkable performance by Shambavi who at only 14 will have plenty of opportunities to repeat her success. A naturally gifted positional player, she has worked hard to hone her calculating skills, to devastating effect in the Oxford League last season.

Elmira opened with the Réti system to reach this position which resembles a Benoni in reverse. She has just played 14.Bh3 to attack the rook.

14…exf4!

An instructive moment. Shambavi sees that for the price of the exchange she can dominate the white squares, consolidate her space advantage and target the weak d3-pawn.

15.Bxf5 Bxf5 16.Nfe1 Qd7 17.Bxf4 Bh3 18.Rf2 Rf8 19.Nf3

19…h6

A very practical move to gain space on the kingside by driving the bishop back. The computer insists that g5 can be played immediately, but it’s a hard line to calculate and the resulting position tricky to assess: 19…g5 20.Bxg5 Bxg5 21.Nxg5 Rxf2 22.Kxf2 Qf5+ 23.Qf3 Qxg5 24.Qd5+ Ne6 25.Qxg5+ Nxg5 with advantage to Black.

20.Qe2 Bg4 21.Nce1 g5 22.Bd2 Bd6 23.Rb1?

White has to try 23.Bxa5 Nxa5 24.b4 Re8 25.Qc2 Re3 26.bxc5 Bxc5 27.Nd2.

23…Re8 24.Qf1 Bh3 25.Ng2 Bf5 26.Nfe1 Rf8 27.Rd1 b6 28.Bc1 Ne5 29.Qe2 Re8

30.Rxf5?!

Understandably, Elmira returns the exchange hoping to relieve some of the pressure, but her pieces remain bottled up on the back ranks. Shambavi’s domination of the board gives her a decisive advantage.

30…Qxf5 31.Qh5 Rf8 32.Qe2 Ng4

33.b3

33.Rd2 was best but then Black breaks through with h4 and h3.

33…Nf2 34.Nc2 Nxd1 35.Qxd1? Qf2+

It’s mate next move.

0–1

Oxford's junior chess players
Before the play-off at Kenilworth (left to right): Shankari, Shambavi, Jan, Ola and Jon

Jan Murawski did well to finish on 4/7 given that his opponents included GM Jones and IM Brandon Clarke.

He considers this his best game, against another promising youngster. Excellent opening preparation and enterprising attacking play bring home the full point, with a few bumps along the way.

So far so theory, according to Jan. He has just played Rb1 with a view to opening the b-file to Black’s king.

19…Qf6

A new move from Lion. Ne6, Ng6 and Qb6 have all been tried before.

20.Bh3 Kb8 21.b4 axb4 22.Rxb4 Bd6 23.Qb1 Ka8 24.a5 Bc7

25.a6

Jan wants to clear another key path to the black king: the h1-a8 diagonal.

25…bxa6 26.Bg2 Rd8 27.Na4 Nxa4 28.Rxa4 Ka7 29.Nd4? Bb6?

Missing a trick: 29…Rxd4! 30.Rxd4 Nf3+ is level.

30.e3

31…Bxd4 31.exd4 Ng4 32.Qa2 c5

33.dxc5?

Giving Lion an opportunity to turn the tables. The best move is 33.Bf1 when Black has nothing better than 33…Rd6 34.dxc5 Re6 35.Rf4 Qe7 36.c6! winning for White.

33…Ne5?

33…Rd1+ 34.Bf1 Ra1!! (the rook cannot be taken because 35…Qxf2+ mates) 35.Rxa6+ Qxa6 36.Qxf7+ Qb7 and Black wins.

34.Qa1 Rd2

Threatening mate in two by 35…Qxf2+.

35.Rxa6+

A nice exchange sacrifice from Jan to expose Lion’s king and remove his own king from danger.

35…Qxa6 36.Qxe5 Rd1+ 37.Kh2 Qc8

37…Qb5 38.Qe4 Kb8 39.Bf3 Rd8 40.Qa8+ Kc7 41.Qa7+ Kc8 42.Qxf7 Qd7 43.Qxh5.

38.Qf4 Qd7

39.c6

39.Qb4! is the most precise when Black must give up his rook to avoid mate: 39…Rd5 40.Qb6+ Ka8 41.Qb3.

39…Qd6?! 40.Qxd6

A neat finish: 40…Rxd6 41 c7 and the pawn queens.

1–0

Juniors shine in Yichen’s simul

Juniors shine in Yichen’s simul

What better way to mark the start of the chess season than invite a strong master to give a simultaneous display?

Talented International Master Yichen Han has an Elo rating of 2429 and is still only 16 years old. Born in the Netherlands, he learned chess using the ‘Step Method’, improved rapidly and qualified for the IM title in 2022. Now a student at Oxford’s Magdalen College School, he is about to apply for a place at university to study mathematics and statistics.

“I’ll have no time to be bored!”

Yichen agreed to take on 17 of our members on Monday 14 October.

Most were facing a master over the board for the first time and played more in the hope than expectation of testing Yichen’s strength, but they were joined by a sprinkling of seasoned league players confident of snatching at least a half-point.

The addition of clocks (80 minutes + 10 seconds per move) upped the ante for the master. Yichen was relishing the challenge. “I prefer quick games and tend to get bored playing a classical time control. This way I’ll have no time to get bored!”.

In effect, Yichen would be playing 17 local league games at once against some of our strongest players, including junior stars Jan Murawski and Shambavi Hariharan. Jan had even beaten Yichen in a regular tournament game!

And how would Yichen fare against his 18th opponent, and arguably his strongest one: the clock?

Even our less experienced players were keen to put up a fight. There were no early baths even though the outcome of at least four or five games seemed decided out of the opening. That was by no means the end of the story though:  Yichen’s 18th opponent could do some heavy lifting for any defender able to stave off checkmate for a while.

Stewart defends as Jan looks on

Club regulars Stuart White and David Gubinelli were holding  their own; Cumnor’s Nigel Moyse seemed cruising comfortably to a draw; while Jan and Shambavi were starting to apply serious pressure and slowing Yichen down.

After an hour time began to tell. Yechu Zhang scored a surprise win on the clock, and Yichen rewarded David’s tough defence with a draw offer that was gratefully accepted.

Yichen took a draw from Jan who was beginning to build an advantage.

Shambavi offered the stiffest opposition and played a blinder, winning a pawn and frustrating Yichen’s attempts to muddy the waters. We’ll analyse her fine win in a future post.

Stuart also grabbed a pawn and made a well-timed draw offer in a position that was technically won for him.

Last man standing Nigel Moyse had a one-on-one blitz shootout with the master. He went astray in an even rook ending but Yichen sportingly made peace in a winning position.

Final score: 11½/17 (Won 9 Drawn 5 Lost 3)

Many thanks to Yichen for being such a good sport.  It was an enjoyable and instructive evening we are all keen to repeat.

Gambit style

Gambit style

Jan Murawski and Shambavi Hariharan played great games in our 6-0 defeat of Didcot 1 last week. Shambavi won a pawn in her favourite Caro-Kann and finished with a mating attack. Jan calmly cruised the complications of a dangerous gambit to expose his opponent’s king.

Jan Murawski – Nick Gough

Oxford City v Didcot 1, 20.03.2024

Albin Counter Gambit

1 d4 d5 2 c4 e5

Rarely seen in master chess these days, the gambit has a few strong grandmaster advocates including Alexander Morozevich.

3 dxe5 d4 4 Nf3 Nc6 5 g3 Be6 6 Nbd2 Qd7 7 a3 Nge7 8 Nb3

White usually plays 8 Bg2 here. One of the early games in this line went: 8…Ng6 9 Qa4 Be7 10 Nb3 0–0–0 11 Bg5 Kb8 12 Bxe7 Qxe7 13 0–0 Bd7 14 Na5 Nxa5 15 Qxa5 Bc6 16 Rfe1 d3 17 Qd2 Qc5 18 exd3 Bxf3 19 Bxf3 Nxe5 20 Re3 Rhe8 21 Rae1 Qd4 22 Bg2 f6 23 Re4 Qb6 24 d4 Rf8 25 Qc3 Nc6 26 d5 Ne5 27 c5 Qa6 28 Bf1 b5 29 cxb6 Qb7 30 bxc7+ Qxc7 31 Rb4+1–0 (Marshall-Janowski, Havana 1913).

8…Ng6 9 Nbxd4

9…Bxc4?!

9…0–0–0 is the best move and can lead to interesting complications: 10 Be3 Ngxe5 11 Nxe5 Nxe5 12 Bg2 Bxc4 13 Qc2 Bc5 14 Nf5 Bxe2 15 Bxc5 Ba6 16 Nd6+ Kb8 17 0–0–0 cxd6 18 Bxd6+ Qxd6 19 Rxd6 Rxd6= 20 Qa4 Rhd8 21 Kb1 Nc4 22 Rc1 Rd4 23 Ka1 f6 24 Qc2 Rd2 25 Qf5 Ne5 26 Bh3 b6 27 Qxh7 Bc4 28 b3 Bxb3 29 Qxg7 Nc4 30 Rxc4 Bxc4 31 Bg4 Re8 0–1 (Levitt-Speelman, British Championship, 1982).

10 Nxc6 Qxc6 11 Bg2 Qa6

This is Nick’s Idea – he’s lost a pawn but Jan will have trouble castling since it allows …Bxe2.
Note that 11…Nxe5?? would lose to 12 Nxe5 Qxg2 13 Qd7 mate. The computer prefers  11…Rd8 12 Qc2 Nxe5 13 Bf4 Be6 14 Qxc6+ Nxc6 15 Bxc7 Rd7 16 Bf4 Be7 17 0–0 Bf6 with some compensation for the pawn.

12 b3 Bb5

13 e6!?

Jan is happy to return his extra pawn to saddle Black with a weak pawn on e6 and open the a1-h8 diagonal for his bishop. A good alternative was 13 Bb2 Be7 14 Qc2 0–0 15 Nd4.

13…f6?

After the game Nick admitted this was a mistake because it allows Jan to castle quickly. 13…fxe6 14 Bb2 Bd6 15 Bxg7 Rg8 16 Bb2 0–0–0 gives Black play for the pawn.

14 0–0 Rd8

Not 14…Bxe2?? 15 Qd7 mate.

15 Qc2 Bd6 16 Nd4 0–0 17 Nxb5 Qxb5 18 a4 Qe5 19 Bb2 Qxe6 20 Bxb7

Jan has regained his pawn and kept the advantage of the two bishops. He is clearly better.

20…Rb8 21 Qe4

Now 21…Qxe4 22 Bxe4 Rxb3 loses to 23 Bd5+.

21…Qh3 22 Bd5+ Kh8 23 Qg2 Qh5 24 e3 Ne5 25 Bd4 a6 26 Rac1 Rfd8

27 Bxe5

Jan makes an excellent practical decision to remove Black’s knight, seeing that his domination of the white squares will keep Nick on the defensive. Also strong was 27 f4 Ng6 28 Ba7 Rb4 29 Bf7 Qg4 30 Rfd1 Ne7.

27…Qxe5 28 Rc4 a5

28…Rxb3 29 Re4 Qxd5 30 Re8+ wins.

29 Re4 Qc3 30 Rh4 h6 31 Qh3

When each player controls squares of opposite colour, the one holding the initiative often has a decisive advantage, especially here where the heavy pieces add force to White’s attack. Jan threatens to win immediately with 32 Rxh6+.

31…Bf8

31…Qc2 is a more active way to secure the kingside. Black can only hope to relieve the pressure by exchanging pieces or sacrificing the exchange on b3, but he is never given the chance..

32 Bc4 Rd6 33 Qg4

33…Rbd8?

The ugly 33…g5 was the only way to hang on.

34 Rxh6+

With mate next move.

1–0

Shambavi carefully guided her passed a-pawn up the board and then unsettled her opponent by switching to full attack mode.

Reed – Hariharan

White’s king looks a little vulnerable whereas Black’s is sitting pretty behind his brick of pawns. Shambavi takes direct action.

36…Qb1! 37 Qe8+ Kh7 38 Qxa4

38…Rh1! 39 f4??

39.Qc4 seems to be best but Black is winning after 39…Qg1+ 40.Kf3 Rxh3+41,Ke2 Qg2 and Qf3+.

39…Qf1+ 40 Kg3 Rxh3 mate

A brutal finish to a smooth positional game.

Shambavi and Jan with their county trophies

Shambavi and Jan are champions!

Congratulations to our new Oxfordshire county champions, Shambavi Hariharan and Jan Murawski.

Shambavi took the Girls’ Under-18 title on tiebreak from the talented Ukrainian Taisiia Kovalova.

Jan lifted the Boys’ Under-13 trophy ahead of Magdalen College School’s Yue Yue Sui (2nd) and Albert Hornsby (3rd).

Jan and Shambavi compete regularly for Oxford City in the First Division of the Oxford League and are gaining valuable experience playing weekend congresses.
