Biel, round 5: all games fully annotated!

[Javier]

Wang grabbed the lead with this, his fourth win. It's kind of sad because Bologan deserved better, the draw being at his reach had he not blundered on move 35. Let's not forget that he didn't have the time that the other players did to prepare against each other, that's an enourmous handicapp at this level...

Black wants to play ...Bf5 and if white goes e4, then the B can return to c8

usual move.} 11. Nd2 Bf5 12. e4 Bc8 13. O-O Ba6 14. Re1 {Was it worth the time

invested? well, white's N would like to get to c4, but with the black B on a6,

that's rather unlikely. This means that the d2 N isn't that useful on d2. In

hesitation from Wang! He's sending out a very clear message: in the Benko,
