He then went on to beat GM Yury Shulman in a tricky rooks, knights and opposite bishops ending (with  his knight stranded, Shulman chose to yield the Exchange on move 34, but it didn't help).

  Ilya Smirin is fresh off as victory over young IM Marc Arnold, whose king was stuck in the center and lacked shelter in a Najdorf Sicilian.

5196

Smirin also took down yesterday's hero, IM Mackenzie Molner, in Round 4. 

Giorgi Kachieshvili defeated GM Alexandra Kosteniuk in Round 4, grabbing the b-pawn and living to tell the tale, as her King march in the ending yielded nothing. 

5192

Jiri Stocek beat IM Irina Krush and then drew with Kacheishvili.

 

At four points are GMs Alex Shabalov, Nikola Mitkov, and Dmitry Gurevich; IMs Molner, Siddharth Ravichandran, Jake Kleiman, and Vladimir Mezentsev; WIM Alisa Melekhina (who upset Krush). 

5194

2540-rated Yaacov Norowitz, whose international title possibilities have been constrained by his refusal to play on the Sabbath also has four points. He drew an interesting tactical game with Ravichandran.
