A Repertoire against the Queen's Gambit Declined with 4.Bg5 by Iniyan Panneerselvam

The Queen’s Gambit Declined (QGD), is a highly popular opening for players of all levels, from absolute beginners to World Champions. Known for giving a solid position, many play this opening from the Black side, however, things aren’t as simple as they seem to be. With an emphasis on 4.Bg5, which was the old mainline played at the highest levels since the World Championship match of the 1920s, we uncover a lot of new ideas.
