Half a point behind are Nic Croad and Bill Forster. Nic didn't have it all his own way against Alan Winfield, and was certainly in an uncomfortable position in the middle game, but recovered and won the endgame. Bill won a high quality game against Ross Jackson, here annotated by both players.
Anthony Ker had another minor lapse and only drew against Michael Sole. There were in fact a lot of upsets in this round, as there have been throughout the tournament. In board order:
Michael Sole (2008) drew with Anthony Ker (2451)
Al Nicholls (1844) beat Edgar Benitez (2040)
Matt Ross (1867) beat TE Tanoi (2016)
Lewis Carroll (1422) drew with Alan Aldridge (1922)
Samuel Darr (1567) drew with Wei Kai Chen (1965)
Lars Stannard (1417) beat Lawrence Farrington (1706)
Geoff Osborne (1287) beat Daniel Kibblewhite (1537)
