The Queen’s Indian Defense is an extremely popular chess opening for black against 1. d4 because it retains a very solid foundation on key positional concepts. In the below chess video, Grandmaster Damian Lemos demonstrates several dangerous attacking ideas for white against the Queen’s Indian Defense by analyzing an impressive victory of Veselin Topalov over Ruslan Ponomariov. Topalov responded to Ponomariov’s play on the queenside by pushing forward to gain space in the center, and then going straight after black’s king with a rapid attack involving a few risky sacrifices. This chess video is an excerpt from the full chess DVD ¨Grandmaster Secrets: Veselin Topalov¨
