Welcome to this Blog post :-)
I upload 3 videos of blitz chess games every day, free on Youtube to watch. Once in a while I also add a rapid game (15 Min per player), all with live comments of course.
Black sets up a Hedgehog fortress. This games shows one of the tools availabe to white to battle this setup.
White offers the c4 pawn, as usual in the Queen's Gambit. Here it's not so easy to get it back.
Here I am fighting my own line against the Kings Indian, the Makagonov Variation. White plays the most critical line to start a fine struggle for the center.
