Opening Basics #34: Dutch defense - Leningrad variation

I cover the most popular line (at least among grandmasters) in the Dutch defense today, the Leningrad variation. Here are the games that I use to illustrate the ideas of this opening: Keres vs. Korchnoi - http://www.chessgames.com/perl/chessg... Mamedyarov vs. Grischuk - http://www.chessgames.com/perl/chessg... Bublei vs. Nepomniachtchi - http://www.chessgames.com/perl/chessg... Gelfand vs. Nakamura - http://www.chessgames.com/perl/chessg...
