Who'd have thunk it? Armenia defeated Russia 2 today (three draws and a Pashikian win on board 4) while Hungary defeated a Kramnik-less Russia 1 (three draws and a Leko grind-out over Grischuk). None of the five Russian teams lead now, but with six rounds left it's way too early to count them out.
The third leading team is Georgia, who walloped the upstart Vietnamese 3.5-.5. As for the other co-leaders entering the round, Poland and the Netherlands, they drew their match 2-2 (Wojtaszek beat van Wely on board 1, but Giri beat Bartel on board 4).
Other important matches that finished with a decisive result: Ukraine beat Bosnia & Herzegovina 3-1, Azerbaijan beat Sweden 2.5-1.5, the Czechs crushed the Mexicans 4-0, the US cruised over Argentina 3-1, Russia 3 beat Israel 2.5-1.5 and India dispatched Bulgaria 3-1. (And they didn't even need Anand!)

A note and a reminder. The reminder is that the scoring is 2-1-0, so the leaders can have 10 points after just five rounds. The note is that tomorrow (Sunday) is a rest day, so round 6 takes place on Monday.
On now to games. I've annotated five from today's round. First, there's Alekseev-Akopian, a crazy draw from the board 1 match. Next is Sokolov-Ivanchuk, an impressive rout by the great Ukranian, putting an end to Sokolov's impressive run (he had been 4-0 with two wins against 2700s). Third was Nakamura-Flores. This wasn't a very impressive game, but the ending gave me the excuse to engage in a little story-telling. Carlsen-Vallejo Pons wasn't so interesting either, once I took a closer look, but it caught my eye at first so it's included too. Finally, Short-Fressinet was a very entertaining game featuring the archaic Max Lange Attack, and it definitely belongs in the list of the day's notable games.
