Subject: Polgar,Ju - Anand,V Why 13. a4 ?
Hello,

Does anybody have a clue why 13.a4 in the following game ?
( The comments are from theweekinchess.com )

Polgar,Ju (2735) - Anand,V (2788) [B17]
FIDE World Championship San Luis, Argentina (1), 28.09.2005

1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nd7 5.Bd3 Ngf6 6.Nf3 Nxe4 7.Bxe4 Nf6
8.Bd3 Bg4 9.Be3 e6 10.c3 [10.h3 Bh5 11.0-0 Bd6 12.c4 0-0 13.Re1 1/2-1/2
Tamin,U-Mai Thi Thanh Houng/Yerevan ARM 1996] 10...Bd6 [10...Be7 11.Qe2
Rc8 12.0-0 Qc7 13.Rfe1 Bd6 14.h3 Bh5 15.Bg5 Be7 16.g3 Nd5 17.Bxe7 Qxe7
18.Kg2 Qf6 19.Be4 a6 20.Qd3 Bxf3+ 21.Qxf3 Qxf3+ 22.Kxf3 0-0 23.Bxd5
cxd5 24.Ke3 Rc6 25.Kd3 Rfc8 26.a4 Kf8 27.f4 g6 28.Ra3 Rc4 29.Rb3 R8c7
30.Ra1 Ke7 31.Rb6 R4c6 32.Rxc6 Rxc6 33.g4 1/2-1/2
Goergen-Huenemeyer,D/Germany 1993/EXT 2002] 11.h3 Bh5 12.Qe2 Qa5 13.a4
0-0 14.Qc2?! An aggressive attempt which doesn't work out too well.
14...Bxf3 15.gxf3 Qh5 16.0-0-0 Nd5 17.Kb1 b5 With the opposite coloured
castling its a race to decide who arrives first. 18.Rdg1 [18.axb5 cxb5
19.Bxb5 Nxe3 20.fxe3 Qxb5 wins.] 18...f6! Prevents Rg5 19.axb5 cxb5
20.Bc1 Rab8 21.Qe2 Rfe8 22.Qe4 Kh8 23.h4 f5! Black is already looking
quite a bit better. 24.Qe2 Qf7 25.Rg2 Bf4 [25...e5 Is an interesting
alternative.] 26.Rhg1 Rg8 27.Be3 Qd7 28.Qd2 Bd6 29.Bc2?! White drifts
over the next few moves. But its not clear to me what her plan should
be. 29...Qb7 30.Bg5? Things worsen fast now. 30...b4 31.c4 b3! 32.Bd3?



Now white is clearly lost and its simply Anand mopping up. 32...Bb4
33.Qe2 Qa6 34.Bh6 [34.cxd5 Qa2+ 35.Kc1 Rgc8+ 36.Kd1 Qa1+] 34...Nc3+
35.bxc3 Bxc3 36.Kc1 Qa3+ [36...b2+ Is much quicker.] 37.Kd1 Qa1+ 38.Bc1
b2 39.Qe3 Bxd4 40.Qd2 bxc1Q+ 41.Qxc1 Qa2 0-1

I remember going through that game and after 13. a4 I thought that
this is a standard move to keep the Black Queen from going to a4 and
stopping White from castling long (as Judit did in this game).

The best Chess Tiger (14.9) sees at this point is 13. O-O O-O 14. c4
Bc7 15. g3 Qb6 16. Rab1 Qb4 which it rates as 0.20 in Black's favour.
I'll have to run this through Fritz and Shredder to see what they
think.

I must confess I have been watching Judit's games closely and am
disappointed because I was really hoping she would put it to the boys.
Now it seems nothing will stop Topalov.

It seems to me to be a preparation for b4. b4 directly isn't possible
because of Qa3! A possible continuation could be 13.a4 0-0 14.b4 Qd5 15.a5
with a space advantage for white. The Knight on f3 is weak however 15. -
bxf3 16.Qxf3 Qxf3 17.gxf3 and not much attack left, maybe that's why she
chose Qc2?!

Yours Sincerely

Anders Lang

Why do I get the idea that Tamin-Fritz or Fritz-Mai Thi Thanh would have
ended differently?
