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.

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.

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.

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.]
