The heat is on at the 2011 World Chess Cup in Khanty-Mansiysk, as the 16 survivors battle for a place in the quarter-finals.

Of the eight games on the first day in round four, six ended decisively, leaving just two draws!

In the biggest match-up so far, #9 seed Peter Svidler took the lead against #8 seed Gata Kamsky. Another major clash saw Teimour Radjabov draw first blood against Dmitry Jakovenko.

However, not all the ratings favourites got their own way. Alexander Grischuk lost to Vladimir Potkin, and Judit Polgar lost with white against Leinier Dominguez, leaving herself needing a win with black tomorrow to keep her hopes alive.

The results of day 1, round 4 in full:

Judit Polgar (33)	0 v 1	Leinier Perez Dominguez (16)
Peter Svidler (9)	1 v 0	Gata Kamsky (8)
Lazaro Bruzon (52)	½ v ½	Ruslan Ponomariov (4)
Vugar Gashimov (5)	1 v 0	Peter Heine Nielsen (44)
Bu Xiangzhi (50)	½ v ½	Vassily Ivanchuk (2)
Teimour Radjabov (7)	1 v 0	Dmitry Jakovenko (10)
Yaroslav Zherebukh (94)	0 v 1	David Navara (14)
Vladimir Potkin (43)	1 v 0	Alexander Grischuk (6)
