After a couple of close calls and three winless rounds Sergei Tikiakov defeats Judit Polgar in Round 4.

Sergei Tiviakov won the first decisive game of the event. He had a bit of a space advantage against Polgar's Sicilian but her position went down hill fast after she gave up the exchange in what was rather a prosaic win in the end.

Tiviakov,Sergei - Polgar,Judit [B46]
Unive Crown Hoogeveen NED (4), 22.10.2009

1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nc6 5.Nc3 a6 6.g3 d6 7.Bg2 Bd7 8.0-0 Nf6 9.Nxc6 Bxc6 10.a4 Be7 11.Be3 0-0 12.a5 Nd7 13.Qd2

Maybe new.

[13.Qe2 1/2-1/2 Tiviakov,S (2635)-Quezada Perez,Y (2567)/Havana CUB 2008/The Week in Chess 709 (20); 13.Na4 0-1 Begun,S (2200)-Sveshnikov,E (2480)/Riga 1975 (52)]

Position after 29.Nd3

29...Qd4?!

[29...Ree8 looks best.]

30.R3e2 Rb8 31.Nxe5

Whatever Polgar is or was planning hasn't worked and now she's just the exchange down.

31...Qxe5 32.Qd3 h5 33.Rd2 Rb6 34.Qd4 Rxb3 35.Qxd6 Qxd6 36.Rxd6 Be6 37.c5 Ng4 38.c6 Rc3 39.e5 a4 40.Kg1 a3 41.Rd8+ Kh7 42.Rd3

Nicely done, eliminating black's only counterplay.

42...Rc5 43.Rxa3 Nxe5 44.Ra6 g6 45.c7 Bc8 46.Rd6 Ng4 47.Rc6 Ra5 48.h3 Ne5 49.Rd6 Rc5 50.Rd5 Rxd5

There is no hope.

1-0

Vassily Ivanchuk's choice of the Exchange Slav as white yielded him nothing, and indeed it might have been Anish Giri that innovated. Anyhow Ivanchuk had no real alternative but to accept the early repetition.

Not the most dynamic choice.

Vassily Ivanchuk

Position after 11...a6

Seems to be the novelty. Quite soon it is clear white doesn't have anything.

[11...Be7; 11...Rc8]

12.Rac1 Be7 13.f3 Bg6 14.Nxg6 hxg6 15.Bxc6 bxc6 16.Rc2 c5 17.Rfc1 c4 18.e4 Bd6 19.Bxd6 Qxd6 20.exd5

Allowing a capture on h2.

20...Qxh2+ 21.Kf1 Qh1+ 22.Kf2 Qh4+ 23.g3

[23.Ke2 exd5 24.Nxd5 0-0 25.Qxd7 Rfe8+ isn't the way forward either.]

23...Qh2+ 24.Ke3 Qh6+ 25.Kf2 Qh2+ 26.Ke3 Qh6+ 1/2-1/2
