Round 1 of the Bilbao Chess Masters Final will start momentarily, with the following pairings:
Caruana - Carlsen
Aronian - Karjakin
Anand - Vallejo
I'll have more to say about round 4 of London later today; in brief, the two decisive games were Grischuk beating Mamedyarov in a lively game and Gelfand beating Wang Hao when the latter blundered into mate in a rook ending. Gelfand is in clear first with 3/4, half a point ahead of Grischuk and Leko.
