FIDE Master Charles Galofre brings us an in-depth look at playing the Grand Prix Attack against the Sicilian. In particular, he provides excellent "follow up material" to Dzindzichashvili's incredible videos on the subject. He describes how to play against black's doubled c-pawns: Surrounding the pawns positionally; creating king-side attacking chances; using critical squares while keeping the position closed for the knights -- are all just some of the techniques you will learn from this video!
