GM Alejandro Ramirez continued his dominating performance at the 111th U.S. Open and Jerry Hanken Memorial in Irvine by beating GM Alexander Shabalov last night in a wildly tactical 8th round game.
With the victory, Ramirez has the best chance of winning the tournament. For a comprehensive report written before the 8th round, see "Ramirez & Shabalov Lead in Irvine" at the USCF site. Among the more interesting news it mentions: former Kenilworth Chess Club president and founding member Mike Wojcio won the golf tournament (which he also directs).
There are a number of bloggers reporting from the scene, including Dana MacKenzie, Mark Ginsburg, and Polly Wright. You can see today's final round online at Monroi.
