GM Ben Finegold delivers a very interesting lecture on the strategic ideas behind the Isolated Queen’s Pawn to advanced students at Chess Club and Scholastic Center of Saint Louis. He starts by exploring a game of his own. His lecture finishes with a classic game between Garry Kasparov and Anatoly Karpov, their White Key Symphony Game. (GM Finegold calls it the White Square Symphony Game.)
Kasparov loses, playing the Petrosian Variation of the QGD. First, he has an IQP. Then he doesn’t. Then, he has an IQP again.
I’ve included the PGN for the White Key Symphony Game after the video.
