The games of round one were played on June 19 and June 20, with tie-breaks on the evening of June 20. Four of the sixty-four scheduled round one matches games did not take place at all: Morozevich, Milov, Shulman and Hjartarson all failed to appear for their first game; their opponents (Elarbi, Neelotpal, Tkachiev and Kudrin) progressed into round two by default. Top seed Topalov had problems with his flight into Libya, and the start of his first game had to be postponed until 5 pm. The seeding system in operation, whereby the top seed plays the bottom seed, the number 2 plays number 127, number 3 plays number 126 and so on, meant that serious round one upsets were unlikely, and indeed there were few surprises. Several of the top players, among them Ye (seeded 12), Azmaiparashvili (14) and Rublevsky (17) required the first pair of tie-break games to advance, and Vallejo Pons (21) only went through after the two five-minute games, but in the end, all progressed as expected. The biggest first-round upset in terms of rating difference was Kritz (rated 2534 and seeded 105) knocking out Sasikiran (2659 / 24) by winning both standard games. Apart from the defaults, he and Hamdouchi (who beat Motylev) were the only players to overcome a rating difference of more than 100 points to advance to round two.
