Good stuff on ChessBase. Don't miss the endgame between GMs Shabalov and Sargissian, beginning at move 75. (It's hard to win clear first in the Chicago Open unless you win at least one drawn ending!)
I'd just happened to see GM Yermolinsky's instructive comments on the Shabalov-Sargissian game on ICC this past Sunday. It's the June 3rd entry in Yermo's "Every Russian Schoolboy Knows" series, "Bishop vs. Knight - Part 1."
