After 5 games of the 2007 Candidates Matches, 3 players have made it through to Round 2. Peter Leko and Gata Kamsky had convincing 3.5-0.5 victories,over Mikhail Gurevich and Etienne Bacrot respectively, while Alexander Grischuk won 3.5-1.5 over Vladimir Malakhov.
In the remaining matches Rublevsky leads 3-2 over Ponomariov, Bareev is 3-2 against Polgar, as is Adams over Shirov. Kasimdzhanov is tied 2.5-2.5 with Gelfand (all games drawn), and in probably the most exciting match Aronian and Carlsen have had 2 wins each and are also tied 2.5-2.5.
Of my pre-tournament predictions, Ponomariov looks to be in the biggest trouble, while Aronian and Gelfand have 1 game in which to do something. Of course being behind doesn't rule out the remaining players, especially if you are Judith Polgar. Her round 5 demolition of Bareev has kept her alive, although she needs to do it again in round 6 just to force tie-breaks.
