In St. Louis, both matches' games ended in draws. Ponomariov seemed to equalize without any real trouble with Black in a Berlin sideline, while Robson-Finegold was a Philidor that ended in a perpetual check after 29 moves. Thus Ponomariov and Robson lead their respective matches with 1.5-.5 scores.
In Havana, Andreikin-Le Quang Liem and Dominguez-Ivanchuk were drawn, while Navara ground down poor Bruzon in 82 to win with Black and move into a tie for first. Le, Navara and Andreikin share first with 4.5/7, putting them a point ahead of Ivanchuk, two points ahead of Dominguez and three points ahead of Bruzon with three rounds to go.
Finally, I was unaware of the 3rd Lublin Union Memorial tournament until "Andrey" wrote me about Alexei Shirov's performance there, but do have a look: he's playing some spectacular chess. Shirov leads this 8-player round-robin with 3.5/4, a point ahead of Grachev, Roiz, Zhigalko and Sasikiran and a full two and a half points ahead of top seed Radoslaw Wojtaszek.
