With one round to go, Gata Kamsky is the sole leader again at the Grand Prix in Thessaloniki, Greece. The American grandmaster celebrated his 39th birthday on Sunday with a quick win against Alexander Morozevich, who thus lost his fourth game in a row. Fabiano Caruana defeated Veselin Topalov to get back to half a point behind Dominguez while Ruslan Ponomariov won a good game against Etienne Bacrot. Tomorrow the last round starts two hours earlier than usual.
