Bulgaria enjoyed the clear lead after round 5 and remained tied for first after six rounds, but their dream of a title were blown up after a 3.5-.5 rout by the Azerbaijani team in round 7. So the Azeris were sure to win, right? After all, they had beaten Russia (in round 6) and Armenia before that, and outrated their eighth round opponents, the Germans, by a healthy margin. Not healthy enough! With three draws and a Naidtisch win over Radjabov on board one, the Germans took the lead.
Or rather, took a share of the lead. The other leaders - who have the better tiebreaks, it must be added - are the Armenians. They nipped Spain in round 6 and France in round 7 before winning more convincingly against the Dutch in round 8. So both Armenia and Germany have 13 team points (both teams are +6 -1 =1 - double the usual point values to get 13 points), and they'll face off in the last round. Azerbaijan and Bulgaria both have 12 points, but are not facing each other. In theory then, there could be a four-way tie for first in the event. The first tiebreak seems to be board points, and if the top match is drawn Armenia would have 23 board points and Germany 22. The most the Bulgarians could finish with is 22.5, if they somehow swept Hungary, and that would leave them behind Armenia. Azerbaijan enters the last round with 20, however, so if they beat Romania 3.5-.5 they could win the title. In fact, their second tiebreak score is better than both Armenia's and Germany's, so it seems that they could win the title even with a 3-1 victory (again, assuming an Armenia-Germany draw).
Other tidbits: the Russians are in a tie for 5th-7th place; on tiebreaks, they're currently 7th. Greece fell back from their earlier great start, but drew in round 8 against Poland. They're presently tied for 11th, and will have a good old-time matchup with Italy. (Send Caruana back - and before the match!)
I'll present some games tomorrow. Meanwhile, the event website, which is worth browsing, is here.
